DESCRIPTION AND OPERATION
HOW TO USE THIS GROUP
The purpose of this group is to show the electrical
circuits in a clear, simple fashion and to make troubleshooting easier. Components that work together
are shown together. All electrical components used in
a specific system are shown on one diagram. The feed
for a system is shown at the top of the page. All
wires, connectors, splices, and components are shown
in the flow of current to the bottom of the page. Wiring which is not part of the circuit represented is referenced to another page/section, where the complete
circuit is shown. In addition, all switches, components, and modules are shown in the at rest position with the doors closed and the key removed
from the ignition.
If a component is part of several different circuits,
it is shown in the diagram for each. For example, the
headlamp switch is the main part of the exterior
lighting, but it also affects the interior lighting and
the chime warning system. It is important to realize that no attempt is made on the diagrams to
represent components and wiring as they
appear on the vehicle. For example, a short
piece of wire is treated the same as a long one.
In addition, switches and other components are
shown as simply as possible, with regard to
function only.

SECTION IDENTIFICATION
Sections in Group 8W are organized by sub-systems. The sections contain circuit operation descriptions, helpful information, and system diagrams. The
intention is to organize information by system, consistently from year to year.
CONNECTOR/GROUND LOCATIONS
Section 8W-90 contains connector/ground location
illustrations. The illustrations contain the connector
name (or number)/ground number and component
identification. Connector/ground location charts in
Section 8W-90 reference the illustration number for
components and connectors.
Section 8W-80 shows each connector and the circuits involved with that connector. The connectors
are identified using the name/number on the Diagram pages.
SPLICE LOCATIONS
Splice Location charts in Section 8W-70 show the
entire splice, and provide references to other sections
the splice serves.
Section 8W-95 contains illustrations that show the
general location of the splices in each harness. The
illustrations show the splice by number, and provide
a written location.

NOTES, CAUTIONS, and WARNINGS
WIRE CODE IDENTIFICATION
Throughout this group additional important information is presented in three ways; Notes, Cautions,
and Warnings.
NOTES are used to help describe how switches or
components operate to complete a particular circuit.
They are also used to indicate different conditions
that may appear on the vehicle. For example, an
up-to and after condition.
CAUTIONS are used to indicate information that
could prevent making an error that may damage the
vehicle.
WARNINGS provide information to prevent personal injury and vehicle damage. Below is a list of
general warnings that should be followed any time a
vehicle is being serviced.
Each wire shown in the diagrams contains a code
(Fig. 1) which identifies the main circuit, part of the
main circuit, gauge of wire, and color. The color is
shown as a two letter code which can be identified by
referring to the Wire Color Code Chart (Fig. 2)
WARNING: ALWAYS WEAR SAFETY GLASSES FOR
EYE PROTECTION.
WARNING: USE SAFETY STANDS ANYTIME A PROCEDURE REQUIRES BEING UNDER A VEHICLE.
Fig. 1 Wire Code Identification
WARNING: BE SURE THAT THE IGNITION SWITCH
ALWAYS IS IN THE OFF POSITION, UNLESS THE
PROCEDURE REQUIRES IT TO BE ON.
WARNING: SET THE PARKING BRAKE WHEN
WORKING ON ANY VEHICLE. AN AUTOMATIC
TRANSMISSION SHOULD BE IN PARK. A MANUAL
TRANSMISSION SHOULD BE IN NEUTRAL.
WARNING: OPERATE THE ENGINE ONLY IN A
WELL-VENTILATED AREA.
WARNING: KEEP AWAY FROM MOVING PARTS
WHEN THE ENGINE IS RUNNING, ESPECIALLY THE
FAN AND BELTS.
WARNING: TO PREVENT SERIOUS BURNS, AVOID
CONTACT WITH HOT PARTS SUCH AS THE RADIATOR, EXHAUST MANIFOLD(S), TAIL PIPE, CATALYTIC CONVERTER, AND MUFFLER.
WARNING: DO NOT ALLOW FLAME OR SPARKS

DESCRIPTION AND OPERATION (Continued)
CIRCUIT IDENTIFICATION
All circuits in the diagrams use an alpha/numeric
code to identify the wire and its function (Fig. 3). To
identify which circuit code applies to a system, refer
to the Circuit Identification Code Chart. This chart
shows the main circuits only and does not show the
secondary codes that may apply to some models.
For viewing connector pin outs, with two terminals
or greater, refer to section 8W-80. This section identifies in-line connectors by number, and component
connectors by name. If a component has two or more
connectors they will be identified as C1, C2, C3...etc.
This sections also provides terminal numbering, circuit identification, wire colors, and functions.
All connectors are viewed from the terminal end
unless otherwise specified. To find the connector location in the vehicle refer to section 8W-90. This section uses the connector identification number from
the wiring diagrams to provide a figure number reference.
TAKE OUTS
The abbreviation T/O is used in the component
location section to indicate a point in which the wiring harness branches out to a component.
CONNECTOR AND SPLICE IDENTIFICATION
Fig. 3 Circuit Identification
CONNECTORS
Connectors shown in the diagrams are identified
using the international standard arrows for male and
female terminals (Fig. 4). A connector identifier is
placed next to the arrows to indicate the connector
number (Fig. 4).
The connector and splice numbering used in this
service manual is different than the numbering used
in other service manuals. This numbering change is
due to the unique wiring harnesses used in this vehicle.
The connector and splice numbering for this vehicle has a letter prefix to identify what harness the
connector/splice is located in. A list of these letter
designations follows:
• B- Body or EDW harness
• C- Dome harness
• D- Door harness
• E- Engine harness
• F- Fuel rail harness
• J- Jumper harness
• L- Liftgate harness
• P- Instrument panel harness
• S- Seat harness
• T- Trailer tow harness
When looking at a splice reference the alpha code
for what harness the splice is located in will come
first, then an S to indicate a splice, and finally the
splice number. An example of this would be ES02.
• E- Indicates splice is in the engine harness
• S- Indicates a splice
• 02- Indicates what splice it is in the harness
SYMBOLS
Various symbols are used throughout the Wiring
Diagrams. These symbols can be identified by referring to the symbol identification chart (Fig. 5).
ELECTROSTATIC DISCHARGE (ESD) SENSITIVE
DEVICES
Fig. 4 Connector Identification
All ESD sensitive components are solid state and a
symbol (Fig. 6) is used to indicate this. When han-

dling any component with this symbol comply with
the following procedures to reduce the possibility of
electrostatic charge build up on the body and inadvertent discharge into the component. If it is not
known whether the part is ESD sensitive, assume
that it is.
(1) Always touch a known good ground before handling the part. This should be repeated while handling the part and more frequently after sliding
across a seat, sitting down from a standing position,
or walking a distance.
(2) Avoid touching electrical terminals of the part,
unless instructed to do so by a written procedure.
(3) When using a voltmeter, be sure to connect the
ground lead first.
(4) Do not remove the part from its protective
packing until it is time to install the part.
(5) Before removing the part from its package,
ground the package to a known good ground on the
vehicle.

door lock motors, power windows, and various engine
solenoids.
A special symbol is used to identify these in the
wiring diagrams (Fig. 8).
Fig. 6 Electrostatic Discharge Symbol
FASTENERS
CAUTION: At no time when servicing a vehicle, can
a sheet metal screw, bolt, or other metal fastener be
installed in the strut tower to take the place of an
original plastic clip. Also, NO holes can be drilled
into the front strut tower in the area shown in (Fig.
7) for the installation of any metal fasteners into the
strut tower. Because of the minimum clearance in
this area (Fig. 7) installation of metal fasteners
could damage the coil spring coating and lead to a
corrosion failure of the spring. If a plastic clip is
missing, or is lost or broken during servicing a
vehicle, replace only with the equivalent part listed
in the parts catalog.
POSITIVE TEMPERATURE COEFFICIENT
Positive Temperature Coefficient (PTC) devices are
being used for circuit protection. These PTC’s act like
a solid state fuse. They are located in the junction
block, and are used to protect such items as: power
Fig. 8 Positive Temperature Coefficient Symbol
DIAGNOSIS AND TESTING
TROUBLESHOOTING TOOLS
When diagnosing a problem in an electrical circuit
there are several common tools necessary. These tools
are listed and explained below.
• Jumper Wire - This is a test wire used to connect two points of a circuit. It can be used to bypass
an open in a circuit.
WARNING: NEVER USE A JUMPER WIRE ACROSS
A LOAD, SUCH AS A MOTOR, CONNECTED
BETWEEN A BATTERY FEED AND GROUND.
• Voltmeter - Used to check for voltage on a circuit. Always connect the black lead to a known good
ground and the red lead to the positive side of the
circuit.
8W - 01 - 6
8W - 01 GENERAL INFORMATION
NS/GS
DIAGNOSIS AND TESTING (Continued)
CAUTION: Most of the electrical components used
in today’s vehicle are solid state. When checking
voltages in these circuits use a meter with a 10-megohm or greater impedance.
• Ohmmeter - Used to check the resistance
between two points of a circuit. Low or no resistance
in a circuit means good continuity.
CAUTION: - Most of the electrical components used
in today’s vehicle are Solid State. When checking
resistance in these circuits use a meter with a
10-megohm or greater impedance. In addition, make
sure the power is disconnected from the circuit.
Circuits that are powered up by the vehicle electrical system can cause damage to the equipment and
provide false readings.
TROUBLESHOOTING TESTS
Before beginning any tests on a vehicles electrical
system use the Wiring Diagrams and study the circuit. Also refer to the Troubleshooting Wiring Problems section in this section.
TESTING FOR VOLTAGE
(1) Connect the ground lead of a voltmeter to a
known good ground (Fig. 10).
(2) Connect the other lead of the voltmeter to the
selected test point. The vehicle ignition may need to
be turned ON to check voltage. Refer to the appropriate test procedure.
• Probing Tools - These tools are used for probing
terminals in connectors (Fig. 9). Select the proper
size tool from Special Tool Package 6807, and insert
it into the terminal being tested. Use the other end
of the tool to insert the meter probe.
Fig. 9 Probing Tool
INTERMITTENT AND POOR CONNECTIONS
Most intermittent electrical problems are caused
by faulty electrical connections or wiring. It is also
possible for a sticking component or relay to cause a
problem. Before condemning a component or wiring
assembly check the following items.
• Connectors are fully seated
• Spread terminals, or terminal push out
• Terminals in the wiring assembly are fully
seated into the connector/component and locked in
position
• Dirt or corrosion on the terminals. Any amount
of corrosion or dirt could cause an intermittent problem
• Damaged connector/component casing exposing
the item to dirt and moisture
• Wire insulation that has rubbed through causing
a short to ground
• Wiring broke inside of the insulation
Fig. 10 Testing for Voltage
TESTING FOR CONTINUITY
(1) Remove the fuse for the circuit being checked
or, disconnect the battery.
(2) Connect one lead of the ohmmeter to one side
of the circuit being tested (Fig. 11).
(3) Connect the other lead to the other end of the
circuit being tested. Low or no resistance means good
continuity.
TESTING FOR A SHORT TO GROUND
(1) Remove the fuse and disconnect all items
involved with the fuse.
(2) Connect a test light or a voltmeter across the
terminals of the fuse.
(3) Starting at the fuse block, wiggle the wiring
harness about six to eight inches apart and watch
the voltmeter/test lamp.
(4) If the voltmeter registers voltage or the test
lamp glows, there is a short to ground in that general area of the wiring harness.

(1) Refer to the wiring diagrams and disconnect or
isolate all items on the fused circuit.
(2) Replace the blown fuse.
(3) Supply power to the fuse by turning ON the
ignition switch or re-connecting the battery.
(4) Start connecting the items in the fuse circuit
one at a time. When the fuse blows the circuit with
the short to ground has been isolated.
TESTING FOR A VOLTAGE DROP
(1) Connect the positive lead of the voltmeter to
the side of the circuit closest to the battery (Fig. 12).
(2) Connect the other lead of the voltmeter to the
other side of the switch or component.
(3) Operate the item.
(4) The voltmeter will show the difference in voltage between the two points.
Fig. 12 Testing for Voltage Drop
TROUBLESHOOTING WIRING PROBLEMS
When troubleshooting wiring problems there are
six steps which can aid in the procedure. The steps
are listed and explained below. Always check for nonfactory items added to the vehicle before doing any
diagnosis. If the vehicle is equipped with these items,
disconnect them to verify these add-on items are not
the cause of the problem.
(1) Verify the problem.
(2) Verify any related symptoms. Do this by performing operational checks on components that are
in the same circuit. Refer to the wiring diagrams.
(3) Analyze the symptoms. Use the wiring diagrams to determine what the circuit is doing, where
the problem most likely is occurring and where the
diagnosis will continue.
(4) Isolate the problem area.
(5) Repair the problem.
(6) Verify proper operation. For this step check for
proper operation of all items on the repaired circuit.
Refer to the wiring diagrams.

CHARGING SYSTEM . . . . . . . . . . . . . . . . . . . . . 4
DESCRIPTION AND OPERATION
CHARGING SYSTEM
The charging system is an integral part of the battery and starter systems. Since these systems work
together, any diagnosis and testing should be done in
conjunction.
The charging system is protected by a 10 gauge
fusible link located in the A11 circuit. The A11 circuit
is connected to the battery feed bus bar of the Power
Distribution Center (PDC) and the generator.
The generator is case-grounded through its attaching bracket. This generator uses a voltage regulator
internal to the Powertrain Control Module (PCM).
When the vehicle is running, battery voltage is
applied to the generator field terminal through the
A142 circuit, on all engine applications. This circuit
is controlled by the contact side of the Automatic
Shut-Down (ASD) relay. The ground, or voltage regulated side, of the generator field is controlled by the
K20 circuit. Circuit K20 connects to cavity 4 of the
PCM.
When there is current present in the field, and the
rotor is turning, the stator in the generator produces
a B+ voltage that is supplied to the battery through
the A11 and A0 circuits. The A11 circuit is connected
to the output terminal of the generator and the battery feed bus bar of the PDC. The A0 circuit is a
direct battery feed from the battery to the PDC.
Grounding for the system is accomplished at the
battery negative terminal. These grounds go to the
engine and body.
HELPFUL INFORMOATION
• Inspect for a blown fusible link in the A11 circuit between the generator and the PDC
• For additional information on charging system
diagnosis, refer to the appropriate group of the Service Manual

STARTING SYSTEM (DIESEL) . . . . . . . . . . . . . . 4
STARTING SYSTEM . . . . . . . . . . . . . . . . . . . . . . 4
DESCRIPTION AND OPERATION
STARTING SYSTEM
The Power Distribution Center (PDC) supplies battery voltage to the engine starter motor solenoid
through circuit T40 when the coil side of the engine
starter motor relay energizes. Circuit A1 contains a 40
amp fuse (cavity 5), and feeds the contact side of the
engine starter motor relay. Both the 40 amp fuse and
the engine starter motor relay are located in the PDC.
Power for the coil side of the relay is supplied on
circuit F45 when the ignition switch is moved to the
START position. Circuit F45 is protected by a 3 amp
Positive Temperature Coefficient (PTC) located in
PTC cavity 10 of the junction block. Power for the
PTC is supplied on circuit A41. This circuit connects
between the ignition switch and the PTC.
Circuit A1 supplies battery voltage for the A41 circuit when the ignition switch is in the START position. The A1 circuit is protected by a 40 amp fuse
located in cavity 5 of the PDC.
Ground for the engine starter motor relay is supplied
on circuit K90. This circuit connects from the relay to
the Powertrain Control Module (PCM), cavity 8.
The PCM monitors the engine RPM and will
remove the ground path for circuit K90 once the
RPM has reached a predetermined level. This prevents the operator from over cranking the engine or
attempting to crank the engine when it is running.
Circuit A0 (battery positive cable) supplies battery
voltage to the engine starter motor when the solenoid
energizes. Ground for the engine starter motor is
supplied through the starter motor case.
HELPFUL INFORMAITON
• Check for blown engine starter motor fuse in
cavity 5 of the PDC
• Check the PTC located in PTC cavity 10 of the
junction block
• With the gear selector in the PARK or NEUTRAL position, move the ignition key to the START
position and listen for the starter motor relay to
click. The engine starter motor relay is located in the
PDC.
• Check for a good ground at the engine starter
motor
• Refer to the appropriate section of the service
manual of the diagnostic test procedures manual

is supplied from three sources. One is a direct battery feed on circuit A5. This circuit is protected by a
20 amp fuse located in the Power Distribution Center
(PDC) cavity 14. This circuit is also spliced and supplies power for the transmission control relay.
Power is also supplied, to the TCM, on circuit F45.
This is the power supply is for the engine starter
relay, coil side, and is HOT in the START position
only. The F45 circuit is protected by a 3 amp Positive
Temperature Coefficient (PTC) located in PTC cavity
10 of the junction block.
Power for the PTC is supplied on circuit A41 from
the ignition switch. Battery voltage for the A41 circuit is supplied by circuit A1 when the ignition
switch is in the START position.
The A1 circuit originates in the Power Distribution
Center (PDC) and is protected by a 40 amp fuse
located in cavity 5.
Circuit F11 also supplies power to the TCM and is
HOT when the ignition switch is in the OFF/RUN/
START position. This circuit is protected by a 10 amp
fuse located in the cavity 2 of the junction block.
Power for the fuse is supplied on circuit A81. This
circuit, A81, is powered by circuit M1 from the PDC.
Circuit M1 is protected by a 10 amp fuse located in
cavity 10 of the PDC.

Ground for the TCM is supplied on the Z13 circuit,
which is a power ground, and circuit Z14, which is a
signal ground. These ground circuits are spliced in
with several other ground circuits and terminate at
the body ground under the battery tray and the
engine ground located on the engine block.
The CCD Data Bus is used to allow the controller
to communicate with other controllers and the universal data link connector. The circuits involved are,
D1 for CCD (+), and D2 for CCD (-).
Circuits D6 and D21 are also used to allow the
TCM to communicate with other controllers and the
universal data link connector.
TRANSMISSION CONTROL RELAY
The transmission control relay, located in the
Power Distribution Center (PDC), is used to power
the Transmission Solenoids and Pressure Switches.
Power for the coil side of the relay is supplied from
the TCM on circuit T15. Ground for the coil side is
provided on circuit Z1.
When the relay is energized, contacts inside the
relay CLOSE and connect circuits A5, which is a
direct battery feed, and circuit T16, which connects
to the solenoid and pressure switch assembly. Circuit
T16 is also spliced to the TCM and is used to control
the switched battery feed.
BACK-UP LAMPS (ETAX)
The operation of the back-up lamps is covered in
the Transmission Range Switch (TRS) circuit description in this section.

DESCRIPTION AND OPERATION (Continued)
BACK-UP LAMPS (MANUAL TRANSMISSION)
Power for the back-up lamp switch is supplied on
circuit F20. This circuit is protected by a 10 amp fuse
located in cavity 12 of the junction block.
When the operator places the vehicle in REVERSE
the back-up lamp switch is CLOSED connecting circuits F20 and L1. The L1 circuit connects from the
switch to the back-up lamps.
SOLENOIDS AND PRESSURE SWITCHES
The Solenoid and Pressure Switch assembly,
located on the transmission, is used to control the
shifting of the transmission. Power for the assembly
is provided on circuit T16 from the transmission control relay. The Transmission Control Module (TCM)
provides the ground path for the various solenoids
and pressure switches depending on operating conditions. This assembly is also case grounded to the
transmission.
The following circuits are controlled by the TCM
for the Solenoid and Pressure Switch assembly.
• T20- Low/Reverse solenoid
• T19- 2/4 solenoid
• T60- Overdrive solenoid
• T59- Underdrive pressure switch
• T50- Low/Reverse pressure switch
• T47- 2/4 pressure switch
• T9- Overdrive pressure switch
TRANSMISSION RANGE SWITCH
The Transmission Range Sensor (TRS) is located
internal to the transmission. This sensor provides the
Transmission Control Module (TCM) with information on shift lever position, contains the transmission
temperature sensor, and contains the switch for the
back-up lamps.
Operation of the transmission temperature sensor
and the back-up lamps is covered in this section.
Circuit T1 provides an input to the TCM when the

This circuit is also the ground circuit for the coil side
of the engine starter motor relay.
The TRS is case grounded to the transmission.
Power for the back-up lamp portion of the TRS is
supplied by circuit F20. This circuit is HOT in the
RUN position only, and protected by a 10 amp fuse
located in cavity 12 of the junction block.
When the operator places the vehicle in REVERSE
circuits F20 and L1 are connected. The L1 circuit is
connected to the back-up lamps, automatic day/night
mirror, and/or the All-Wheel Drive (AWD) solenoids,
if equipped.
TRANSMISSION TEMPERATURE SENSOR
The transmission temperature sensor is used to
monitor the temperature of the transmission fluid.
The sensor is a variable resistor and is part of the
Transmission Range Switch (TRS).

circuit connects to cavity 54 of the TCM connector.
Ground for the sensor is supplied on circuit T13.
This circuit is spliced with the turbine speed and output speed sensor. This circuit connects to cavity 13 of
the TCM connector.
TURBINE SPEED SENSOR
The Turbine Speed sensor is used to measure the
speed of the torque converter turbine. Power for the
sensor is provided from the Transmission Control
Module (TCM) to the sensor on circuit T52. Ground
for the sensor is provided on circuit T13. This ground
is spliced and shared with the Output Speed sensor.
OUTPUT SPEED SENSOR

VEHICLE SPEED CONTROL . . . . . . . . . . . . . . . . 6
DESCRIPTION AND OPERATION
VEHICLE SPEED CONTROL
The vehicle speed control system is powered by the
Powertrain Control Module (PCM). The vehicle speed
control switches, located in the steering wheel, use
resistors internal to the switch to send a signal to
the PCM indicating what the operator is requesting.
The V37 circuit, from cavity 41 of the PCM supplies
power for the switch. Circuit Z2 is the ground for the
switch.
The V37 and Z2 circuits are spliced internal to the
clockspring to provide power and ground for the
switches.
On vehicles equipped with an electronically controlled transaxle, when the system is turned ON, the
vehicle is moving forward, vehicle speed is above 35
mph (50km/hr), and the SET switch is pressed, the
PCM looks at the vehicle speed through the vehicle
speed input provided from the Transmission Control
Module (TCM) to the PCM on circuit G7. On vehicles
equipped not equipped with an electronically controlled transaxle, the PCM receives the vehicle speed
input from the Vehicle Speed Sensor (VSS).
With this information, the PCM sends a signal to
the vehicle speed control servo, on the V36 circuit,
and the servo applies vacuum to hold the desired
speed. Circuit V36 connects to cavity 78 of the PCM.
When the operator selects the COAST feature in
the system, the PCM measures the resistance on the
V37 circuit and uses this information to apply voltage on the V35 circuit, which is the vent side of the
vehicle speed control servo. Circuit V35 connects to
cavity 80 of the PCM.
Grounding for the vehicle speed control servo is
done on the Z1 circuit. An additional input to the
servo is provided by the stop lamp switch on the V30
circuit. When the operator presses on the brakes the
ground path for the V30 circuit is broken. This break
in the ground path causes the vehicle speed control
servo to vent and disengage the system.
Circuits V32 and K29 are used as inputs to the
PCM to indicate when the operator is applying the
brakes, as vehicle speed control is canceled when this
happens. Circuit V32 connects to cavity 5 of the
PCM. Circuit K29 connects to cavity 62 of the PCM.
CRUISE (VEHICLE SPEED CONTROL) ON LAMP
The cruise lamp is used to indicate to the operator
when the vehicle speed control is ON. The signal to
illuminate the lamp is carried over the CCD Bus
from the Body Control Module (BCM).
The BCM receives information on vehicle speed
control ON from the Powertrain Control Module
(PCM) over the CCD Bus. This lamp is also illuminated, for a few seconds, when the ignition switch is
moved from the OFF to RUN position as a bulb
check.

DESCRIPTION AND OPERATION
INSTRUMENT CLUSTER OPERATION
The Instrument Cluster, located on the left side of
the instrument panel, provides the operator with
gauges and warning lamps indicating vehicle operation. All gauges, regardless of engine type, are driven
by the CCD Bus from the Body Control Module
(BCM).
The indicator lamps for the Seat Belt, Charging
System, Cruise (Vehicle Speed Control), Low Fuel,
Low Washer Fluid, Door Ajar, and Liftgate Ajar are
also driven by the BCM.
Battery voltage for the instrument cluster is provided from two different sources. One is the F11 circuit, which supplies battery voltage for the cluster.
This circuit is protected by 10 amp fuse and located
in cavity 2 of the junction block. This fuse is HOT
when the ignition switch is in the UNLOCK/RUN/
START position.
Power for the fuse is supplied on circuit A81 from
the ignition switch. Circuit M1 supplies power for the
A81 circuit at the ignition switch.
The M1 circuit is the Ignition-Off Draw circuit, and
is protected by a 10 amp fuse located in cavity 10 of
the Power Distribution Center (PDC). This circuit is
also a constant battery feed for the instrument cluster.
Illumination lamps, internal to the cluster, receive
battery voltage on the E2 circuit. This circuit originates in the BCM and lamp intensity is controlled by
the BCM. Ground for the lamps is provided on the Z1
circuit.

CCD BUS
The CCD Bus is used to supply all of the communications between the Body Control Module (BCM),
other vehicle controllers, and the instrument cluster.
The bus wires are a twisted pair. There are two different circuits used for the bus.
The positive side of the bus wire is accomplished
on the D1 circuit, and the negative is on the D2 circuit.
GROUND CIRCUIT
Ground for the instrument cluster gauges and
warning lamps is supplied on circuit Z2. This circuit
terminates at the instrument panel ground.
Ground for the illumination lamps in the instrument cluster is supplied on circuit Z1.
SPEEDOMETER
The speedometer receives its information across
the CCD Bus from the Body Control Module (BCM).
Information on vehicle speed is transmitted from the
Powertrain Control Module (PCM) across the CCD
Bus to the BCM.
The PCM receives its information on vehicle speed
from the G7 circuit, for vehicles equipped electronic
automatic transaxle, from the Transmission Control
Module (TCM).
On vehicles equipped with the automatic transaxle,
vehicle speed is sent to the PCM on the G7 circuit
from the Vehicle Speed Sensor (VSS), which is
mounted in the transmission. For additional information on VSS operation refer to section 8W-30.
The BCM calculates the position of the speedometer pointer based on the input from the PCM and
adjusts the position of the gauge pointer as necessary. This signal is sent over the CCD Bus to the
instrument cluster.

DESCRIPTION AND OPERATION (Continued)
TACHOMETER
ODOMETER
The tachometer receives its information across the
CCD Bus from the Body Control Module (BCM).
Information on engine RPM is transmitted from the
Powertrain Control Module (PCM) across the CCD
Bus to the BCM. The BCM calculates the position of
the tachometer pointer based on the input from the
PCM and adjusts the position of the gauge pointer to
the necessary position. This signal is sent over the
CCD Bus to the instrument cluster.
The Odometer function of the instrument cluster is
controlled by the Body Control Module (BCM). To calculate the proper milage for the vehicle the BCM
receives information from the Powertrain Control
Module (PCM) and the Transmission Control Module
(TCM)(if equipped) over the CCD Bus. It then calculates this information and sends the proper signal
over the CCD Bus to the instrument cluster.
TRIP ODOMETER
ENGINE COOLANT TEMPERATURE GAUGE
The engine coolant temperature gauge receives its
information across the CCD Bus from the Body Control Module (BCM). The engine coolant temperature
sensor uses a variable resistor to send a signal to the
Powertrain Control Module (PCM) indicating coolant
temperature. The PCM then sends this information
to the BCM across the CCD Bus.
The BCM calculates the position of the engine coolant temperature gauge, and based on the information
received from the PCM it adjusts the position of the
gauge pointer. This signal is sent over the CCD Bus
to the instrument cluster.
FUEL GAUGE
The Body Control Module (BCM) calculates the
pointer position of the fuel gauge based on the input
of the fuel tank gauge level sending unit relative to
fuel tank ground. The G4 circuit sends the signal to
the BCM.
The fuel pump module, located in the fuel tank,
contains the fuel pump and the variable resistor for
the fuel gauge. As the position of the float arm
changes, the resistor changes the current flow
through the G4 circuit. The change in current flow is
then measured by the BCM and pointer position is
adjusted to reflect the fuel tank level. The signal is
sent over the CCD Bus to the instrument cluster.
PRNDL (ELECTRONIC)
On vehicles equipped with an automatic transmission an electronic PRNDL is used to indicate to the
operator gearshift position.
When the ignition switch is in the OFF (unlock),
RUN, or START position the Body Control Module
(BCM) transmits a message over the CCD Bus
instructing the instrument cluster to illuminate the
proper display.
The BCM receives its information over the CCD
Bus from the Transmission Control Module (TCM) on
gearshift position. When the ignition switch is moved
to the RUN position, the BCM instructs the instrument cluster to illuminate all segments of the
PRNDL as a check.
The Trip Odometer function of the instrument cluster is controlled by the Body Control Module (BCM).
All information is sent across the CCD Bus.
CRUISE (VEHICLE SPEED CONTROL) ON LAMP
The cruise lamp is used to indicate to the operator
when the vehicle speed control is ON. The signal to
illuminate the lamp is carried over the CCD Bus
from the Body Control Module (BCM).
The BCM receives information on vehicle speed
control ON from the Powertrain Control Module
(PCM) over the CCD Bus. This lamp is also illuminated, for a few seconds, when the ignition switch is
moved from the OFF to RUN position as a bulb
check.
SEAT BELT INDICATOR
The fasten seat belt indicator is used with the
warning chime to tell the operator to fasten the seat
belt. The seat belt switch is located in the left B-Pillar and is normally OPEN when the seat belt is
buckled.
If the seat belt is not buckled, the switch CLOSES,
and a ground path is completed on the G10 circuit to
the Z1 circuit. The G10 circuit is connected to the
Body Control Module (BCM). When the ground path
is complete a signal is sent over the CCD Bus to the
instrument cluster.
This illuminates the lamp in the instrument cluster. Ground for the seat belt switch is terminated at
the left side cowl.
When the ignition switch is moved to the START
position, the lamp is illuminated as a bulb check.
Logic internal to the BCM determines the length of
time the lamp remains illuminated.

DESCRIPTION AND OPERATION (Continued)
DOOR AJAR INDICATOR LAMP
CHARGING SYSTEM WARNING LAMP
The door ajar warning lamp is used to alert the
operator that a door is ajar. A chime tone is used
along with the lamp for an audible warning.
There are four door ajar switches used. The
switches for the right and left front doors are case
grounded. The switches for the passenger, and drivers, rear doors provide an input to the Body Control
Module (BCM) on the G76 and G77 circuit. When
any of the switches are grounded (door ajar), and the
vehicle is moving, the Body Control Module (BCM)
sends a signal over the CCD Bus to the instrument
cluster for lamp illumination.
The Charging System lamp is used to alert the
operator that the charging system voltage has fallen
below the normal operating range. When the Powertrain Control Module (PCM) determines a problem, a
message is sent across the CCD Bus to the Body
Control Module (BCM).
The BCM processes this message and sends a signal on the CCD Bus to the instrument cluster for
lamp illumination. This lamp also is illuminated, for
a few seconds, when the ignition switch is moved
from the OFF to the RUN position as a bulb check.
LOW WASHER FLUID LAMP
LIFTGATE AJAR INDICATOR LAMP
The liftgate ajar warning lamp is used to alert the
operator that a liftgate is ajar. A chime tone is used
along with the lamp for an audible warning.
Circuit G78 connects from the Body Control Module (BCM) to the liftgate ajar switch. The switch is
normally OPEN with the liftgate closed. When the
liftgate is opened the switch CLOSES completing a
path to ground on circuit Z1. This circuit terminates
at the liftgate ground.
When the BCM sees that the liftgate is ajar it
sends a message across the CCD Bus to the instrument cluster for lamp illumination.
The low washer fluid lamp is used to alert the
operator that the washer fluid level has fallen below
a pre-determined level.
The Body Control Module (BCM) controls the operation of the lamp based on the input from the low
washer fluid level switch located in the washer fluid
reservoir.
Circuit G29 connects from the BCM to the switch.
The switch is normally OPEN. When the fluid level
is below the pre-determined level the switch
CLOSES completing a path to ground on circuit Z1.
This circuit terminates at the right cowl panel.
HELPFUL INFORMATION
LOW FUEL LAMP
The illumination of the lamp is controlled by the
Body Control Module (BCM). When the BCM detects
a low fuel condition based on the input of the fuel
gauge level, circuit G4, it illuminates the lamp.
This is accomplished by the BCM sending a message over the CCD Bus to the instrument cluster for
lamp illumination.
• Check the 10 amp fuse located in cavity 10 of
the PDC
• Check the 10 amp fuse located in cavity 2 of the
junction block.
• Check for a good ground at the instrument panel
ground
• For additional diagnostic test, refer to the appropriate group of the Service Manual or the Diagnostic
Test Procedures Manual

DESCRIPTION AND OPERATION
INTRODUCTION
There are three levels of ventilation systems available on this vehicle. There is a heater only system, a
base A/C-Heater system, and a dual zone A/C-Heater
system. A optional rear A/C-Heater system is also
available.
Both the heater only and the two A/C-Heater systems share many of the same components. The circuit descriptions for all three are covered in this
section. Where one system is different in one aspect
or another it will be noted in the circuit descriptions,
and the wiring diagrams.
The HVAC controls all functions of the system by
measuring the resistance in circuits, supplying power
and ground to components, activating motors, and
controlling the ground path for the blower motor.
HVAC CONTROL
Battery voltage for the HVAC control is supplied
on circuit V23. This circuit is HOT in the START/
RUN position and connects from the ignition switch
to the HVAC control.
Circuit A1 supplies voltage to the ignition switch.
This circuit is protected by a 40 amp fuse located in
cavity 5 of the Power Distribution Center (PDC).
Ground for the HVAC control is supplied on circuit
Z1 and Z2. The Z2 circuit terminates at the instrument panel ground, and the Z1 circuit terminates at
the blower motor ground.
The Z2 circuit is spliced internal to the HVAC control and supplies the ground path for the other
switches and indicators in the switch pod, in addition
the Z2 circuit supplies ground for the temperature
control(s), and mode select switch.
The HVAC control uses resistors in the temperature control(s) and the mode switch to determine
operators request

spliced and provides a ground path for the other sensors.
A/C OPERATION
When the operator requests A/C operation by
pressing the A/C switch in the HVAC control, or by
turning the defrosters ON, a signal is sent to the
Powertrain Control Module (PCM) requesting A/C
operation, on circuit C103.
The PCM interprets this request and supplies a
ground path for the A/C compressor clutch relay (coil
side), providing the pressures and temperatures in
the A/C system are in the proper ranges. The PCM
looks at the engine coolant temperature and the
HVAC control reads the evaporator temperature sensor.
Circuit C13 connects from the relay coil, ground
side, to the PCM. Power for the coil side is supplied
on circuit F87 (A142 on diesel applications). This circuit is HOT in the START and RUN position only,
and protected by a 9 amp Positive Temperature Coefficient (PTC) located in PTC location 1.
Power for the PTC is supplied on circuit A21. This
circuit connects from the ignition switch to the PTC.
Power for the A21 circuit is supplied on circuit A1.
This circuit originates at the Power Distribution Center (PDC) and is protected by a 40 amp fuse located
in cavity 5.
When the relay is energized, contacts in the relay
CLOSE connecting circuit #10 and circuit C3. The
#10 circuit is protected by a 15 amp fuse located in
cavity 18 of the PDC. Circuit C3 connects from the
relay to the A/C compressor clutch.
The A/C compressor clutch receives this current
and creates a magnetic field, energizing the clutch.
The ground path for the A/C compressor clutch is on
circuit Z1.
The A/C compressor clutch has a diode located in
it. This diode is used to control the induced voltage
resulting from the magnetic field collapsing when the
clutch is disengaged.
The A/C compressor clutch relay is also used by the
PCM to disengage the compressor in a Wide-Open
Throttle (W.O.T.) condition.
To monitor the pressure in the system the PCM
looks at the A/C pressure transducer. Circuit K6 is
the 5 volt feed from the PCM to the sensor, and cir-

Power for the radiator fan solid state relay is supplied on circuit A16. This circuit is HOT at all times
and protected by a 40 amp fuse located in cavity 4 of
the Power Distribution Center (PDC).
Ground for the relay is supplied by the Powertrain
Control Module (PCM) on circuit K173. The PCM
determines the need for radiator fan operation, and
the speed at which it operates, by looking at several
items including engine coolant temperature and A/C
operation.
Circuit C23 connects from the relay to the radiator fan
motors. Ground for the fans is supplied on circuit Z1.
RADIATOR FAN (DIESEL)
The radiator fan system on this vehicle is controlled by the Powertrain Control Module (PCM) and
three (3) relays. The PCM controls the ground side of
the relay coil(s).
LOW SPEED
When LOW speed radiator fan operation is required
the PCM provides a ground path for circuit C24. This
causes the contacts in relay #2 to CLOSE connecting
circuits A16 and C25. The A16 circuit is protected by a
40 amp fuse located in cavity 4 of the Power Distribution Center (PDC). Circuit C25 connects from the relay
to the low speed radiator fan motor.
Power is passed through the motor to relay #1 and
through the CLOSED contacts to circuit C27. The
C27 circuit connects to the high speed fan motor then
to ground on circuit Z1.
HIGH SPEED
When HIGH speed radiator fan operation is
required the PCM provides a ground path for circuit
C137. This causes the contacts in relay #1 and #3 to
CLOSE connecting circuits A17 and C117. The A17
circuit is protected by a 40 amp fuse located in cavity
8 of the Power Distribution Center (PDC). Circuit
C116 connects from the relay to the high speed radiator fan motor.

When the operator selects the LOW speed position,
power is supplied on circuit C71 through the blower
motor to circuit C7. The C7 circuit connects from the
blower motor to the HVAC control, HIGH speed contact.
Voltage is passed through the HVAC control to circuit C107. The C107 circuit connects from the HVAC
control to the blower motor resistor.
The voltage is passed through the blower motor resistor to circuit C4 which connects from the resistor back
to the HVAC control and to ground on circuit Z1.
M1, M2, M3 SPEED OPERATION
Operation of the M1, M2, and M3 speeds is the
same as the LOW speed except circuit C5 is used for
M1, circuit C6 is used for M2, and circuit C104 is
used for M3.
HIGH SPEED OPERATION
In the HIGH speed mode the voltage is passed
through the blower motor to ground through the
CLOSED contacts in the blower motor switch. There
are no resistors used in the HIGH speed mode.
BLOWER MOTOR (REAR)
Power for the rear blower motor is supplied on circuit C40. This circuit is protected by a 20 amp fuse
located in cavity 11 of the junction block. At LOW
and MEDIUM speeds, ground for the rear blower
motor passes through the temperature sensor and
one or more resistors, depending on speed selection.
Two switches operate the rear blower motor by
supplying ground; the front control switch and the
rear control switch. The front control switch must be
in the ON position for the rear control switch to operate the rear blower motor.

and both resistors to circuit C60. Circuit C60 connects
to the front control switch. The front control switch
connects the blower motor to ground on circuit Z1.
When the front control switch is in the MEDIUM
position, ground passes through the temperature
switch, and one resistor to circuit C65. Circuit C65
connects to the front control switch. The front control
switch connects the blower motor to ground on circuit
Z1.
If the front control switch is in the HIGH position,
the ground path for the blower motor is on circuit C70
through the front blower switch to ground circuit Z1.
REAR CONTROL SWITCH
For the rear control switch to operate the rear
blower motor, the front control switch must be in the
ON position. Circuit C50 from the rear control switch
connects to the ON terminal of the front control
switch. In the ON position, the front control switch
connects circuit C50 to ground on circuit Z1.
When the rear control switch is in the LOW position and the front control switch is in the ON position, ground passes through the temperature switch,
and both resistors to circuit C60. Circuit C60 connects to the rear control switch. From the rear control switch, ground passes through circuit C50 and
the front control switch to circuit Z1.
When the rear control switch is in the MEDIUM
position and the front control switch is in the ON
position, ground passes through the temperature
switch, and one resistors to circuit C65. Circuit C65
connects to the rear control switch. From the rear
control switch, ground passes through circuit C50
and the front control switch to circuit Z1.
If the rear control switch is in the HIGH position
and the front control switch is in the ON position,
the ground path is on circuit C70 through the rear
control switch. From the rear control switch, ground
passes through circuit C50 and the front control
switch to circuit Z1. In the HIGH position, current
does not flow through the blower motor resistors.

DESCRIPTION AND OPERATION
AIRBAG SQUIB (AIRBAG IGNITER)
AIRBAG CONTROL MODULE (ACM)
DRIVER’S SIDE AIRBAG
Two circuits, R43 and R45, connect the ACM to the
driver’s side Airbag squib (igniter) after passing
through the clock spring connector. Circuit R43 from
cavity 3 of the ACM 4-way connector connects to the
squib. Circuit R45 from cavity 4 of the ACM 4-way
connector connects to the squib. R43 and R45 are a
twisted pair of wires.
Two different circuits supply battery voltage to the
Airbag Control Module (ACM), they are F14 and F23.
Different circuits from the Power Distribution Center
(PDC) and the ignition switch supply battery voltage
to the junction block bus bars.
The F23 circuit supplies battery voltage to the
ACM only when the ignition switch is in the RUN
position. The F14 circuit powers the ACM when the
ignition switch is in either the START or RUN position.
A bus bar internal to the ignition switch connects
the A2 circuit from the junction block to the A22 circuit when the switch is in the RUN position. The A22
circuit supplies battery voltage to the PDC fuse that
feeds the F23 circuit. A 10 amp fuse in the junction
block, cavity 27, protects the A2 and A22 circuits. A
10 amp fuse in cavity 28 of the PDC protects the F23
circuit.
When the ignition switch is in the START/RUN
position, it connects the A1 circuit from the PDC to
the F87 circuit. The F87 circuit supplies battery voltage to the junction block bus bar that feeds the F14
circuit. A 40 amp fuse in cavity 5 of the PDC protects
the A1 and F87 circuits. A 10 amp fuse in cavity 27
of the PDC protects the F23 circuit.
The ACM has a case ground, and an external dedicated ground, circuit Z2. The dedicated ground connects to the ACM bracket.
AIRBAG IMPACT SENSOR
The Airbag Control Module (ACM) uses sensors
internal to it to determine the angle and severity of
an impact.
PASSANGER’S SIDE AIRBAG
Two circuits, R42 and R44, connect the ACM to the
passenger’s side Airbag squib (igniter). Circuit R42
from cavity 1 of the ACM 4-way connector connects
to the squib. Circuit R44 from cavity 2 of the ACM
4-way connector connects to the squib. R42 and R44
are a twisted pair of wires.
AIRBAG WARNING LAMP
Illumination of the Airbag warning lamp is controlled by the Airbag Control Module (ACM). When
the ACM detects a problem in the system it grounds
the R41 circuit. This causes the lamp in the message
center to illuminate.
HELPFUL INFORMATION
• Check for blown fuses in the circuits that connect to the ignition switch and in those that connect
to the ACM
• While the bus bars in the junction block power
the ACM, they also feed additional components on
separate fuse-protected circuits
• The ACM has a case ground and an external
dedicated ground. The dedicated ground connects to
the ACM bracket

DESCRIPTION AND OPERATION
INTRODUCITON
The Body Control Module (BCM) used in this vehicle provides a communication interface with the
other controllers and modules. The BCM is also
responsible for controlling various functions in the
vehicle, for example Vehicle Theft Security System
(VTSS). Where the BCM is used for those items, the
operation is described in that section of the wiring
diagrams.
This section provides an overview of the functions
controlled by the BCM, and the other functions supported by the BCM.
BATTERY FEED
Battery feed for the Body Control Module (BCM) is
supplied on two circuits.
Circuit M1 supplied battery voltage to the BCM at
all times. This is the Ignition-Off Draw circuit, and is
protected by a 10 amp fuse located in cavity 10 of the
Power Distribution Center (PDC). This circuit is
HOT at all times. This fuse is removed during vehicle shipping to prevent excessive battery draw.
The F11 circuit also supplies voltage to the BCM.
This circuit is HOT when the ignition switch is in the
ON, RUN, and START positions. This circuit is protected by a 10 amp fuse located in cavity 2 of the
junction block.
CCD BUS
To allow the Body Control Module (BCM) to communicate and control various vehicle functions the
BCM uses the CCD bus. This is a twisted pair of
wires that connects to the other modules and controllers. Circuits D1 and D2 are used for the communication interface.
Circuit D1 is used for the CCD (+), and circuit D2
is used for CCD (-).

GROUND
Ground for the Body Control Module (BCM) is supplied on circuit Z2. This circuit connects to two pins
at the BCM. The grounding points for the Z2 are the
same, at the instrument panel ground.
ILLUMINATED ENTRY
On vehicles equipped with Remote Keyless Entry
(RKE) the Body Control Module (BCM) will turn ON
the interior lamps with a valid UNLOCK signal from
the RKE transmitter. For operation of the interior
lamps, refer to section 8W-44.
SEAT BELT CHIME
The seat belt chime is used to indicate to the operator that the seat belt is not buckled with the ignition switch in the ON position.
Circuit G10 is connected between the Body Control
Module (BCM) and the seat belt switch. The switch
is normally OPEN with the seat belt buckled. If the
seat belt is not buckled the switch is CLOSED completing a path to ground on circuit Z1. This ground
terminates at the left cowl panel.
The BCM reads that the switch is CLOSED and
activates the chime.
EXTERIOR LAMP ON CHIME
The exterior lamp ON chime is used to indicate to
the operator that the lamps have been left ON with
the key removed from the ignition, and the driver’s
door OPEN.
Circuit G75 is used for the input to the BCM from
the driver’s door ajar switch. This switch is case
grounded and normally OPEN with the door closed.
Circuit G26 is used for the key-in ignition switch.
This switch is normally OPEN with the key removed
from the ignition. When the key is in the ignition the
switch completes a path to ground on circuit Z1.

DESCRIPTION AND OPERATION (Continued)
TURN SIGNAL ON CHIME
WARNING LAMP ANNOUNCEMENT CHIME
The turn signal ON chime is used to alert the operator that the turn signals have been ON for an
extended distance.
The Body Control Module (BCM) uses inputs from
the turn signal switch and the CCD bus (vehicle distance) to determine if the chime should be sounded.
The warning lamp announcement chime is used to
indicate to the operator that a warning lamp is illuminated. The Body Control Module (BCM) monitors
the following items to determine if the chime should
be sounded.
• Volts low
• Low fuel level
• Low washer fluid level
• Door/Liftgate ajar
KEY-IN IGNITION ON CHIME
The key-in ignition chime is used to alert the operator that the key is in the ignition with the ignition
OFF and the driver’s door ajar.
Circuit G75 is used for the input to the BCM from
the driver’s door ajar switch. This switch is case
grounded and normally OPEN with the door closed.
Circuit G26 is used for the key-in ignition switch.
This switch is normally OPEN with the key removed
from the ignition. When the key is in the ignition the
switch completes a path to ground on circuit Z1.
DOME LAMP ON CHIME
The dome lamp ON chime is used to indicate to the
operator that the dome lamps are ON with the drivers door OPEN.
Circuit G75 is used for the input to the Body Control Module (BCM) that the driver’s door is ajar. This
switch is normally OPEN with the door closed. When
the door is OPEN a path to ground is completed
through the case grounded switch.
Circuit M32 is used for the dome lamp ON input to
the BCM. This circuit connects from the BCM to the
headlamp switch. When the dome lamps are ON a
ground path is completed through the switch to circuit Z1.
LOW OIL PRESSURE CHIME
The low oil pressure chime is used to indicate to
the operator that the oil pressure has fallen below a
pre-determined pressure.
Circuit G6 is used as the input to the Body Control
Module (BCM). This circuit connects from the low oil
pressure lamp in the instrument cluster and the oil
pressure switch.
The oil pressure switch is normally OPEN with
normal oil pressure. If the oil pressure is to low the
switch completes a path to ground. This illuminates
the lamp in the instrument cluster and the BCM
activates the chime.
ENGINE TEMPERATURE CRITICAL CHIME
The engine coolant temperature critical chime is
used to alert the operator that the coolant temperature has risen above a pre-determined level.
The Body Control Module (BCM) monitors coolant
temperature from information received across the
CCD bus from the PCM.
HELPFUL INFORMATION
• Check the 10 amp fuse located in cavity 10 of
the PDC
• Check the 10 amp fuse located in cavity 2 of the
junction block
• Check the grounding points at the instrument
panel ground
• Refer to the appropriate section of the Service
Manual or Diagnostic Test Procedures manual.

Circuit descriptions for the Vehicle Theft Security
System (VTSS), airbag, anti-lock, turn signal indicators, and high beam indicator lamps are described in
the appropriate sections. Refer to those sections for
circuit descriptions.
LOW OIL PRESSURE LAMP
The low oil pressure lamp is used to indicate to the
operator that the engine oil pressure has fallen below
a pre-determined level.
Power for the lamp is supplied on circuit V23. This
circuit is HOT in the START and RUN position only
and protected by a 20 amp fuse located in cavity 3 of
the junction block.
Circuit A21 connects from the ignition switch to
the fuse to supply power.
Battery voltage for the A21 circuit is supplied on
circuit A1. This circuit originates at the Power Distribution Center (PDC) and is protected by a 40 amp
fuse located in cavity 5.
Circuit G6 connects from the message center
through the Body Control Module (BCM) to the oil
pressure switch. The engine oil pressure switch is a
case grounded switch that is normally OPEN with

BRAKE WARNING LAMP
The brake warning lamp is used to alert the operator that the brake system pressure has fallen below
a pre-determined level. It is also used to indicate
when the parking brake is applied.
Power for the lamp is supplied on circuit V23. This
circuit is HOT in the START and RUN position only,
and protected by a 20 amp fuse located in cavity 3 of
the junction block.
Circuit A21 connects from the ignition switch to
the fuse to supply power.
Battery voltage for the A21 circuit is supplied on
circuit A1. This circuit originates at the Power Distribution Center (PDC) and is protected by a 40 amp
fuse located in cavity 5.
Ground for the lamp is supplied either by the
brake pressure switch or the park brake switch on
circuit G9. The parking brake switch is normally
OPEN. When the switch is CLOSED the ground path
is completed through the case grounded switch.
The brake pressure switch is normally OPEN.
When the system pressure is below the pre-determined level the switch CLOSES completing a path to
ground.
ENGINE COOLANT TEMPERATURE LAMP
When the ignition switch is in the START or RUN
position, it connects circuit A1 from fuse 5 in the
Power Distribution Center (PDC) to circuit A21. Circuit A21 powers circuit V23 through fuse 3 in the
junction block. Circuit V23 supplies power to the
message center for the engine coolant temperature
lamp. The Body Control Module (BCM) provides
ground for the engine coolant temperature lamp on
circuit G2.
SERVICE ENGINE SOON LAMP
The service engine soon lamp is used to indicate to
the operator a problem in the engine control system.
If a problem is detected, the Powertrain Control Module (PCM) sends a message over the CCD Bus to the
Body Control Module (BCM).
The BCM interprets this message and sends a signal to the message center to illuminate the lamp.

DESCRIPTION AND OPERATION
RADIO OPERATION
There are four audio systems offered on this vehicle. The base systems use four speakers. The optional
systems have eight speakers, power amplifiers at the
speakers, name brand speaker relay, and a radio
choke.
All of the audio systems are powered by a 10 amp
fuse located in cavity 8 of the junction block on circuit X12. This fuse is HOT when the ignition switch
is in the ACCESSORY or RUN position.
Circuit A31 supplies power to fuse 11. The A31 circuit, which receives it’s power from the ignition
switch, on circuit A1, is protected by a 40 amp fuse
located in cavity 5 of the Power Distribution Center
(PDC).
Both the standard and optional radios use an
external case ground. This case ground attaches to
the rear of the radio.
RADIO MEMORY
Both the base and premium systems use the M1
circuit to maintain radio memory. This circuit is connected to the battery through the Power Distribution
Center (PDC), and protected by a 10 amp IgnitionOff Draw (IOD) fuse located in cavity 10 of the PDC.
The M1 circuit is used to supply power to the Body
Control Module (BCM), Power Mirrors, and the
Power Door Locks. This fuse is also used in several
other circuits, refer to section 8W-12 for additional
information on the IOD fuse. The IOD fuse is
removed during vehicle shipping to prevent excessive
battery draw.
RADIO ILLUMINATION
When the parking lamps or the headlamps are ON,
circuits E2 and E17 are used to power the radio illumination lamps. Circuit E2 is controlled by the Body
Control Module (BCM). Circuit E17 is controlled by
the park lamp switch.

DESCRIPTION AND OPERATION
REAR WINDOW DEFOGGER
The rear window defogger system uses a relay
located in the junction block. This relay is protected
by two fuses and controlled by the HVAC control.
When the operator pushes the ON switch for the rear
window defogger, a signal is sent to the HVAC control and the control supplies a ground path for circuit
C14.
This causes the coil side of the relay to energize,
connecting circuit A4 to circuits C15, and C16. The
C16 circuit is protected by a 10 amp fuse located in
cavity 7 of the junction block, and used to supply
power for the power mirror heaters. Refer to section
8W-62 for circuit descriptions.
The F20 circuit that is used to power the coil side
of the relay is protected by a 10 amp fuse located in
cavity 12 of the junction block and is HOT in the
RUN position only.
The A4 circuit, which is used to supply power to
the contact side of the relay, is protected by a 40 amp
fuse located in cavity 1 of the Power Distribution
Center (PDC) and HOT at all times.
Circuit C15 connects from the relay to the rear
window defogger grid. Ground for the grid is supplied
on circuit Z1, and terminates at the liftgate ground.
The rear window defogger grid consists of two BUS
bars and grid lines that form a parallel circuit. When
current flows through the grid the grid lines heat up
and transfer the heat to the window.
When the system is in operation a Light Emitting
Diode (LED) located in the A/C-Heater control is illuminated.
HELPFUL INFORMATION
• Check the 10 amp fuse located in cavity 12 of
the junction block
• Check the 40 amp fuse located in cavity 1 of the
PDC
• Check for broken grid lines on the window
• Check for a broken bus bar or disconnected
leads at the window
• Check for a good ground
WIPER DEICER
The operation of the windshield wiper deicer is
controlled by HVAC control. When the operator
selects the DEFROST mode, the HVAC control supplies a ground path for circuit C66.

DESCRIPTION AND OPERATION
COMPASS MINI-TRIP COMPUTER . . . . . . . . . . . 4
DESCRIPTION AND OPERATION
COMPASS MINI-TRIP COMPUTER
The Compass Mini-Trip Computer (CMTC) is a display head used to provide the following information
to the vehicle occupants:
• Compass and outside air temperature
• Current fuel economy
• Average fuel economy
• Distance to empty
• Trip odometer
• Elapsed time
The CMTC receives all information across the CCD
Bus from various controllers and modules, except for
outside ambient air temperature.
Power for the CMTC is supplied by circuit F20.
This circuit connects from the ignition switch to the
CMTC and is HOT in the RUN position only.
Circuit A22 connects from the ignition switch to a
10 amp fuse located in cavity 10 of the junction
block.
Power for the A22 circuit, and fuse 10, is supplied
on circuit A2. This circuit is protected by a 40 amp
fuse located in cavity 2 of the Power Distribution
Center.
Ground for the CMTC is provided on circuit Z2.
This circuit terminates at the right cowl panel.
The outside air temperature sensor is located forward of the radiator, rear of the fascia. Circuits G31
and G32 are used to transmit the outside air temperature reading to the CMTC. These circuits are a
twisted pair.
HELPFUL INFORMATION
• Check the 40 amp fuse located in cavity 2 of the
PDC
• Check the 10 amp fuse located in cavity 10 of
the junction block
• Refer to the appropriate group of the Service
Manual or the Diagnostic Test Procedures manual

GENERAL INFORMATION
INTRODUCTION
The front end lighting system used in this vehicle
is controlled by the Body Control Module (BCM), the
headlamp switch, low beam relay, and high beam
relay.
The system has three modes of operation:
• Parking lamps
• Headlamps ON low beam
• Headlamps ON high beam
• Optical horn
On vehicle built for sale in Canada the headlamps
operate, at reduced intensity, when the ignition
switch is in the ON position.
DESCRIPTION AND OPERATION
PARKING LAMPS ON
When the operator turns the parking lamps ON, a
ground path is completed on circuit L308 from the
Body Control Module (BCM), through the CLOSED
contacts in the headlamp switch to ground on circuit
Z1.
Voltage for the L308 circuit is supplied from the
BCM.
The BCM interprets the operators request and supplies a ground path for circuit L97. This circuit connects from the BCM to the coil side of the park lamp
relay, located in the Power Distribution Center
(PDC).
Ground to the coil side of the relay causes the contacts in the relay to CLOSE connecting circuits A6
and L7. Circuit L7 supplies power to fuses 4 and 6.
Circuit A6 is a direct battery feed, HOT at all times,
and protected by a 40 amp fuse located in cavity 6 of
the PDC.
Circuit L77 connects from fuse 6, a 15 amp, to the
left front park/turn signal lamp. Ground for the lamp
is supplied on circuit Z1 and terminates at the left
cowl panel.

select switch in the multi-function switch. With the
beam select switch in the LOW position the ground
path is supplied through the CLOSED contacts in
the switch to circuit L94.
Circuit L94 connects from the switch to the coil
side of the LOW beam relay, located in the Power
Distribution Center (PDC).
The ground path on the coil side of the relay
causes the contacts in the relay to CLOSE connecting
a direct battery feed to fuse 22 and 23 in the PDC.
Circuit L43 connects from fuse 23, a 15 amp, to the
LOW beam side of the left headlamp. Ground for the
lamp is supplied on circuit Z1 and terminates at the

(PDC) feeds the stop lamp switch. A 20 amp fuse in
the PDC, cavity 16, protects circuit F32.
When the operator presses the brake pedal, the
stop lamp switch CLOSES and connects circuit F32
to circuit L50. Circuit L50 connects to the right and
left stop lamps. The L50 circuit is also spliced and
supplies power for the Center High Mounted Stop
Lamps (CHMSL).
Circuit Z1 provides ground for the stop lamps and
CHMSL lamps. The grounding point for the left and
right stop lamps terminates at the rear body ground.
The grounding point for the CHMSL terminates at
the liftgate ground.
BACK-UP LAMPS
Operation of the back-up lamps is covered in section 8W-31.

to the left front turn signal lamp. Ground for the
lamp is supplied on circuit Z1 and terminates at the
left cowl panel.
Circuit L63 connects from the combination flasher
to the left rear turn signal lamp and side repeater
lamp. This circuit is also spliced and provides an
input to the Body Control Module (BCM) to indicate
the turn signals are ON and to the indicator lamp in
the message center.
RIGHT TURN SIGNAL
When the operator selects the right turn signal circuit L302 is connected to the Z1 ground circuit
through the turn signal switch.
The combination flasher senses the position of the
switch and supplies power to the L60 and L62 circuits.
Circuit L60 connects from the combination flasher
to the right front turn signal lamp. Ground for the
lamp is supplied on circuit Z1 and terminates at the
right cowl panel.
Circuit L62 connects from the combination flasher
to the right rear turn signal lamp and side repeater
lamp. This circuit is also spliced and provides an
input to the Body Control Module (BCM) to indicate
the turn signals are ON and to the indicator lamp in
the message center.

DESCRIPTION AND OPERATION
WINDSHIELD WIPERS
The windshield wiper system is powered by a 30
amp fuse located in cavity 9 of the Power Distribution Center (PDC). This fuse is HOT at all times.
The BCM controls all functions of the wiper system. This is accomplished through a multi-plexed
input from the wiper switch to the BCM on circuit
V52. Circuit Z20 is the sensor return ground for the
wiper switch to the BCM.
INTERMITTENT WIPER OPERATION
When the operator selects intermittent wiper operation, a multi-plexed signal is sent to the Body Control Module (BCM) on the V52 circuit. The BCM then
grounds circuit V14, which is the coil side of the
wiper ON wiper relay. This causes the relay to switch
from its normally grounded position to its powered
position. This connects the output of fuse 9, a 30 amp
in the PDC to circuit V5.
The V5 circuit is connected to the HI/LOW Wiper
relay LOW speed side. Voltage is passed through the
relay to circuit V3, then to the LOW speed side of the
wiper motor. Ground for the wiper motor is provided
on circuit Z1.
When the wiper motor completes one cycle, the
BCM turns OFF the motor by deactivating the wiper
relays. The amount of delay between wipes is dependent on the voltage level being sent to the BCM from
the wiper switch.
As the windshield wiper motor turns, the park
switch internal to the motor moves from its grounded
position to the open RUN position. The BCM uses
input from the park switch, on circuit V7, for wiper
position and system operation.
The delay times are also compensated for vehicle
speed. If the vehicle is moving less than 10 mph, the
delay time is doubled. Once the vehicle speed exceeds
10 mph, the normal delay times are used.

WIPER AFTER WASH
When the wash button is pressed momentarily a
signal is sent to the Body Control Module (BCM) on
circuit V10. The BCM then turns the wipers ON low
speed for three consecutive wipes after the button is
released. The BCM then grounds circuit V14, which
is the coil side of the wiper ON wiper relay. This
causes the relay to switch from its normally
grounded position to its powered position. This connects the output of fuse 9, a 30 amp in the PDC to
circuit V5.
The V5 circuit is connected to the HI/LOW Wiper
relay LOW speed side. Voltage is passed through the
relay to circuit V3, then to the LOW speed side of the
wiper motor. Ground for the wiper motor is provided
on circuit Z1.
When the wiper motor completes one cycle, the
BCM turns OFF the motor by deactivating the wiper
relays.
As the windshield wiper motor turns, the park
switch internal to the motor moves from its grounded
position to the open RUN position. The BCM uses
input from the park switch, on circuit V7, for wiper
position and system operation.
LOW SPEED OPERATION
When the LOW speed switch is activated a multiplexed signal is sent to the Body Control Module
(BCM) on circuit V52. The BCM then turns the wipers ON low speed by providing a ground path for circuit V14. The BCM then grounds circuit V14, which
is the coil side of the wiper ON relay. This causes the
relay to switch from its normally grounded position
to its powered position. This connects the output of
fuse 9, a 30 amp in the PDC to circuit V5.
The V5 circuit is connected to the HI/LOW Wiper
relay LOW speed side. Voltage is passed through the
relay to circuit V3, then to the LOW speed side of the
wiper motor. Ground for the wiper motor is provided
on circuit Z1.
When the wiper motor completes one cycle, the
BCM turns OFF the motor by deactivating the wiper
relays.

DESCRIPTION AND OPERATION (Continued)
As the windshield wiper motor turns, the park
switch internal to the motor moves from its grounded
position to the open RUN position. The BCM uses
input from the park switch, on circuit V7, for wiper
position and system operation.
HI SPEED OPERATION
When HIGH speed operation is selected, a multiplexed signal is sent to the Body Control Module
(BCM) on circuit V52. The wiper switch also supplies
voltage to the HIGH/LOW wiper relay, coil side on
circuit V16. The BCM then turns the wipers ON by
grounding the V14 circuit.
When the BCM grounds circuit V14, which is the
coil side of the wiper ON relay the relay to switches
from its normally grounded position to its powered
position. This connects the output of fuse 9, a 30 amp
in the PDC to circuit V5.
When the V16 circuit is grounded the HIGH/LOW
relay switches, from its normal position of LOW
speed, to the HIGH speed contact. Ground for the
relay is supplied on circuit Z1 and terminates at the
engine ground.
Power for the windshield wiper motor is supplied
from the HIGH/LOW wiper relay to the motor on circuit V4. Ground for the wiper motor is provided on
circuit Z1.
ators request to a varying analog signal that is sent
to the Body Control Module (BCM) on the V26 circuit.
Each of the switches used in this system use a
Light Emitting Diode (LED) to indicate to the operator what mode the system is in. Power for the LED’s
is supplied from the HVAC control. Ground for the
LED’s is supplied on circuit Z2 and terminates at the
instrument panel ground.
This system is also vehicle speed sensitive.
Power for the rear wiper motor is supplied from
the BCM on circuit V13. The V7 circuit is connected
from the BCM to the motor and used for measuring
the dwell of the motor.
Ground for the wiper motor is supplied on circuit
Z1 and terminates at the liftgate ground.
When the rear washer motor is activated, the BCM
provides a ground path for the V20 circuit. This circuit connects from the pump motor to the BCM.
Power for the washer motor is supplied on circuit
F1. This circuit is protected by a 6 amp Positive Temperature Coefficient (PTC) in location 9 of the junction block.
LOW WASHER FLUID LAMP
Power for the front windshield washer pump is
supplied on circuit F1. This circuit is protected by a 6
amp PTC located in the junction block and HOT in
the ACCESSORY and RUN position only.
When the washer switch is pressed, circuit V10
from the BCM and junction block, is connected to the
Z1 ground circuit. This supplies the ground path for
the pump and allows the pump to run.
The low washer fluid lamp is used to alert the
operator that the washer fluid level has fallen below
a pre-determined level.
The Body Control Module (BCM) controls the operation of the lamp based on the input from the low
washer fluid level switch located in the washer fluid
reservoir.
Circuit G29 connects from the BCM to the switch.
The switch is normally OPEN. When the fluid level
is below the pre-determined level the switch
CLOSES completing a path to ground on circuit Z1.
This circuit terminates at the right cowl panel.

GENERAL INFORMATION
INTRODUCTION
This section of the wiring diagrams covers the
operation of the power windows and the power vent
windows.
DESCRIPTION AND OPERATION
POWER WINDOWS
The power window system is powered by two 9
amp Positive Temperature Coefficients (PTC’s). Both
of the PTC’s are located in the junction block, PTC
locations eight and nine.
The PTC’s receive there feed from the ignition
switch on the A31 circuit. The PTC’s are HOT when
the ignition switch is in the ACCESSORY or RUN
position only.
Circuit F21 is the feed circuit from PTC 8 to the
power window and vent switch that feeds the left
side windows. Circuit F55 is the feed circuit from
PTC 9 to the power window and vent switch that
feeds the right side windows.
The ground path for the power windows is on the
Z1 circuit and terminates at the instrument panel
left side cowl.
Both of the door switches have a Light Emitting
Diode (L.E.D.) located inside of the switch. This diode
allows the operator to see the switch when it is dark.
The diodes are powered by circuit E2. This circuit is
HOT when the headlamp switch is in the PARK or
ON position.
Resistors and diodes internal to the switches are
used for the L.E.D’s. No attempt should be made to
repair these items. If the L.E.D. is not working, the
switch should be replaced.
An express down module is used for the left windows. It allows the operator to latch the switch. Refer
to the power window section in this service manual
for additional information.
LEFT FRONT WINDOW OPERATION

GENERAL INFORMATION
INTRODUCTION
This section of the wiring diagrams is divided into
two sub- sections: power door locks without remote
keyless entry, and power door locks with remote keyless entry.
When referring to the circuit descriptions or wiring
diagrams, ensure you use the correct ones.
DESCRIPTION AND OPERATION
POWER DOOR LOCKS (W/O REMOTE KEYLESS
ENTRY)
The power door lock system is controlled by the
Body Control Module (BCM). The door lock switches,
located in the front doors, are supplied power on the
P96 circuit for the right door switch and the P97 circuit for the left door switch. These circuits are powered by the Body Control Module (BCM).
Both switches have a Light Emitting Diode (LED)
located internal to the switch for night illumination.
Power for the LED’s is supplied on circuit E2. The
E2 circuit is the illumination output from the BCM.
Ground for the switches is supplied on circuit Z2.
These grounds terminate at the instrument panel
right side cowl.
This power door lock system uses two relays
located in the junction block. Power for the coil and
contact sides of the relays is supplied by the A2 circuit.
Circuit A2 is HOT at all times and is protected by
a 40 amp fuse located in cavity 2 of the PDC.
Ground for the coil side of the relays is supplied by
the BCM.
DOOR LOCK/UNLOCK OPERATION
The door lock switches use resistors internal to the
switch. There are different resistors used for the
LOCK and UNLOCK functions. Both switches have
the same amount of resistance for the LOCK and
UNLOCK functions.
When the operator selects the UNLOCK function,
from either switch, voltage is passed through the
CLOSED contacts in the switch, through the appropriate resistor, to the Z2 ground circuit. Circuit P96
connects from the BCM to the right door switch, and
circuit P97 connects to the left door switch.
The BCM processes this request and supplies the
ground path for the coil side of the unlock relay. This
causes the contacts in the relay to switch from its
normally grounded position to connect circuit A2 to
circuits F131, F134, and F136.
Each of these circuits are protected by a different
Positive Temperature Coefficient (PTC) located in the
junction block, and connect to the unlock side of the
motors.
Circuit F131 connects to the left front door motor,
circuit F134 connects to the right front and right side
door motors, circuit F136 connects to the left side
door and the liftgate motor.
Ground for the motors is supplied on circuits F132
and F133. These circuits connect from the motors to
the junction block. At the junction block the ground
circuit is completed through the CLOSED contacts in
the lock relay to the Z1 circuit. The Z1 circuit terminates at the instrument panel left side cowl.
Circuit F132 supplies the ground path for the front
doors and circuit F133 supplies the ground path for
the side doors and the liftgate.
For the LOCK function the circuits are reversed.
Circuits F132 and F133 are the feeds to the motors,
and circuits F131, F134, and F136 are the ground
circuits through the CLOSED contacts in the
UNLOCK relay.
POWER DOOR LOCKS (WITH REMOTE KEYLESS
ENTRY)
The power door lock system is controlled by the
Body Control Module (BCM). The door lock switches,
located in the front doors, are supplied power on the
P96 circuit for the right door switch and the P97 circuit for the left door switch. These circuits are powered by the Body Control Module (BCM).

NS/GS
DESCRIPTION AND OPERATION (Continued)
Both switches have a Light Emitting Diode (LED)
located internal to the switch for night illumination.
Power for the LED’s is supplied on circuit E2. The
E2 circuit is the illumination output from the BCM.
Ground for the switches is supplied on circuit Z2.
These grounds terminate at the instrument panel
right side cowl.
This power door lock system uses three relays
located in the junction block. Power for the coil and
contact sides of the relays is supplied by the A2 circuit.
Circuit A2 is HOT at all times and is protected by
a 40 amp fuse located in cavity 2 of the PDC.
Ground for the coil side of the relays is supplied by
the BCM.
REMOTE KEYLESS ENTRY MODULE
Power for the Remote Keyless Entry (RKE) module
is supplied on circuit M1. This circuit is the IgnitionOff Draw (IOD) circuit and is protected by a 10 amp
fuse located in cavity 10 of the Power Distribution
Center (PDC). This circuit is HOT at all times.
Ground for the module is supplied on circuit Z2
and terminates at the instrument panel ground.
Circuit G96 is connected between the RKE module
and the Body Control Module (BCM). This circuit
supplies the BCM with information on the operators
request. The G96 circuit also supplied an input to the
memory seat module (if equipped).
Circuit D9 is connected from the RKE module to
the BCM and is used for programming the RKE module. Refer to the appropriate section of the Service
Manual or Diagnostic Test Procedure Manual for
RKE programming.
DOOR LOCK/UNLOCK OPERATION
The door lock switches use resistors internal to the
switch. There are different resistors used for the
LOCK and UNLOCK functions. Both switches have
the same amount of resistance for the LOCK and
UNLOCK functions.
When the operator selects the UNLOCK function,
from either switch, voltage is passed through the
CLOSED contacts in the switch, through the appropriate resistor, to the Z2 ground circuit. Circuit P96
connects from the BCM to the right door switch, and
circuit P97 connects to the left door switch.
The BCM processes this request and supplies the
ground path for the coil side of the unlock relay. This
causes the contacts in the relay to switch from its
normally grounded position to connect circuit A2 to
circuits F131, F134, and F136.
Each of these circuits are protected by a different
Positive Temperature Coefficient (PTC) located in the
junction block, and connect to the unlock side of the
motors.
Circuit F131 connects to the left front door motor,
circuit F134 connects to the right front and right side
door motors, circuit F136 connects to the left side
door and the liftgate motor.
Ground for the motors is supplied on circuits F132
and F133. These circuits connect from the motors to
the junction block. At the junction block the ground
circuit is completed through the CLOSED contacts in
the lock relay to the Z1 circuit. The Z1 circuit terminates at the instrument panel left side cowl.
Circuit F132 supplies the ground path for the front
doors and circuit F133 supplies the ground path for
the side doors and the liftgate.
For the LOCK function the circuits are reversed.
Circuits F132 and F133 are the feeds to the motors,
and circuits F131, F134, and F136 are the ground
circuits through the CLOSED contacts in the
UNLOCK, and left front UNLOCK relay.
SLIDING DOOR LOCK MEMORY
When the Body Control Module (BCM) receives a
LOCK request and one or both of the rear doors are
OPEN, and the key is not in the ignition, the BCM
will activate the lock relay again when it receives a
door closed signal from the side door ajar switches.
HELPFUL INFORMATION
• Check the PTC’s located in the junction block.
• Check the 40 amp fuse located in cavity 2 of the
PDC.
• Check the 10 amp fuse located in cavity 10 of
the PDC (RKE only)
• Check for a good door switch ground at the
instrument panel right side cowl
• Refer to the appropriate group of the Service
Manual or the Diagnostic Test Procedures Manual
for further diagnostic procedures

GENERAL INFORMATION
INTRODUCTION
This section of the wiring diagrams is divided into
two sub- sections: power mirrors, and power memory
mirrors. When using the circuit descriptions or the
wiring diagrams, ensure that you are using the correct ones for the system you are working on.
DESCRIPTION AND OPERATION
POWER MIRRORS
The power mirrors use a single switch located on
the left side of the instrument panel. The feed for the
system is supplied from the 15 amp fuse located in
the Power Distribution Center (PDC) cavity 11 (circuit F41). Grounding for the power mirrors is provided through the Z1 circuit, which terminates at the
instrument panel left side cowl.
The power mirror switch also has a Light Emitting
Diode (LED) located in it for night illumination. Power
for the LED is supplied on circuit E2. This is the illumination output from the Body Control Module (BCM).
SWITCH AND MIRROR OPERATION
The power mirror switch has a right and a left
position. Moving the switch to either of these positions changes the voltage path internal to the switch
(changes polarity at the motors).
When the switch is moved to the LEFT position
and mirror movement UP is selected, voltage is supplied through the P71 circuit and the ground path is
through circuit P73. When the DOWN movement is
selected, the power and ground are reversed.
If a LEFT door mirror movement LEFT is selected,
voltage is supplied through the P75 circuit and the
ground is passed through circuit P73. When the left
door mirror RIGHT movement is selected, the power
and ground are reversed.
When the switch is moved to the RIGHT position
and mirror movement UP is selected, voltage is supplied through the P72 circuit and the ground path is
through circuit P70. When the DOWN movement is
selected, the power and ground are reversed.
If a RIGHT door mirror movement LEFT is
selected, voltage is supplied through the P74 circuit
and the ground is passed through circuit P70. When
the left door mirror RIGHT movement is selected,
the power and ground are reversed.
HEATER OPERATION
The mirrors are also equipped with heating elements. These elements are activated when the operator has turned ON the heated rear window. Circuit
C16 provides power for the heaters.
The heated mirrors and heated rear window switch
are protected by a 10 amp fuse located in the junction block cavity 12. Grounding for the mirror heaters is provided on the Z1 circuit and terminates at
the instrument panel left side cowl.
HELPFUL INFORMATION
• Check the 15 amp fuse located in cavity 11 of
the PDC
• Move the switch to its various positions and listen for the motors to click or try to move. Some
movement or clicking indicates a poor connection or a
mechanical problem with a mirror
• Check the grounding location for the mirror
motors and switch
POWER MEMORY MIRRORS
The power memory mirror system used in this
vehicle uses a control module, power mirror switch,
power mirror motors, mirror potentiometers, and a
memory set switch. This control module is also
shared and used for the power memory seat. For
operation of that system, refer to section 8W- 63.
Power for the memory control module is supplied
on two circuits. Circuit F35 provides a constant battery feed. This circuit is protected by a 30 amp circuit breaker located under the drivers seat. Power for
the F35 circuit is supplied on circuit A2. The A2 circuit is HOT at all times and protected by a 40 amp
fuse located in cavity 2 of the Power Distribution
Center (PDC).
The M1 circuit also supplies battery voltage to the
control module. This circuit is the Ignition-Off Draw
(IOD) circuit, and protected by a 10 amp fuse located
in cavity 10 of the PDC.

8W - 62 POWER MIRRORS
NS/GS
DESCRIPTION AND OPERATION (Continued)
Ground for the control module is supplied on circuit Z1. This circuit terminates at the instrument
panel left side cowl.
Power for the mirror switch is supplied on circuit
F41. This circuit is protected by a 15 amp fuse
located in cavity 11 of the Power Distribution Center
(PDC). Grounding for the power mirrors is provided
through the Z1 circuit, which terminates at the
instrument panel left side cowl.
The power mirror switch also has a Light Emitting
Diode (LED) located in it for night illumination.
Power for the LED is supplied on circuit E2. This is
the illumination output from the Body Control Module (BCM).
To control the operation of the mirrors, the circuits
that supply power to the mirror motors are also connected to the control module. Operation of the motors
and ground circuit is the same.
SWITCH AND MIRROR OPERATION
The power mirror switch has a right and a left
position. Moving the switch to either of these positions changes the voltage path internal to the switch
(changes polarity at the motors).
When the switch is moved to the LEFT position
and mirror movement UP is selected, voltage is supplied through the P71 circuit and the ground path is
through circuit P73. When the DOWN movement is
selected, the power and ground are reversed.
If a LEFT door mirror movement LEFT is selected,
voltage is supplied through the P75 circuit and the
ground is passed through circuit P73. When the left
door mirror RIGHT movement is selected, the power
and ground are reversed.
When the switch is moved to the RIGHT position
and mirror movement UP is selected, voltage is supplied through the P72 circuit and the ground path is
through circuit P70. When the DOWN movement is
selected, the power and ground are reversed.
If a RIGHT door mirror movement LEFT is
selected, voltage is supplied through the P74 circuit
and the ground is passed through circuit P70. When
the left door mirror RIGHT movement is selected,
the power and ground are reversed.
HEATER OPERATION
The mirrors are also equipped with heating elements. These elements are activated when the operator has turned ON the heated rear window. Circuit
C16 provides power for the heaters.
The heated mirrors and heated rear window switch
are protected by a 10 amp fuse located in the junction block cavity 12. Grounding for the mirror heaters is provided on the Z1 circuit and terminates at
the instrument panel left side cowl.
MIRROR POTENTIOMETERS
The power mirror control module receives an input
on the mirror position from the potentiometers
located in the mirrors.
There are four potentiometers used in this system,
two in each mirror. Each supplies a different input to
the control module. Circuit P67 provides the input
for the right mirror vertical position. Circuit P68 is
used for the right mirror horizontal position. Circuit
P66 is used as the ground from the right mirror to
the control module.
Circuit P64 is used for the left vertical position.
Circuit P65 is used for left mirror horizontal position.
The P69 circuit is used as the ground from the left
mirror to the control module.
MEMORY SET SWITCH
The memory set switch is used for programming the
desired seat/mirror positions into the control modules
memory. There are three switches used, a set switch,
memory 1, and memory 2. Power for the switches is
supplied from the control module to the switches.
Ground for the switches is supplied on circuit Z1 and
terminates at the instrument panel left side cowl.
Circuit P22 is used for the SET switch. Circuit P23
is used for the memory switch 1, and circuit P24 is
used for the memory switch 2.
REMOTE KEYLESS ENTRY MODULE INPUT
The Remote Keyless Entry (RKE) module provides
an input to the control module to indicate when the
operator is unlocking the doors.
POWER FOLDING MIRRORS
Operation of the power folding mirrors is controlled
by the Body Control Module (BCM) and the power
mirror folding switch. Circuit P136 connects from the
BCM to the power folding mirror switch. In the normal state (mirrors unfolded) circuit P136 connects to
ground on circuit Z1.
When the operator selects FOLD the BCM provides
a ground path for circuit P171. This causes the contacts in the fold relay to CLOSE connecting circuits
F41 and P160. Circuit F41 is the power supply for
the coil and contact side of the relay.
Circuit P160 connects from the relay to the folding
motors. Ground for the motors is supplied on circuit
P159 to the normally CLOSED contacts in the unfold
relay and to ground on circuit Z1.
HELPFUL INFORMATION
• Check the 30 amp circuit breaker located under
the drivers seat
• Check the 40 amp fuse located in cavity 2 of the
PDC
• Check the ground at the instrument panel left
side cowl
• Refer to the appropriate section of the service
manual for additional diagnostic information

HELPFUL INFORMATION
• Check the 30 amp circuit breaker located under
the drivers seat
• Check the 40 amp fuse located in cavity 2 of the
PDC
• Check for a good ground at the instrument panel
left side cowl
POWER MEMORY SEAT
The power memory seat system used in this vehicle uses a control module, power seat switch, power
seat motors, seat potentiometers, and a memory set
switch. This control module is also shared and used
for the power memory mirrors. For operation of that
system, refer to section 8W-62.
Power for the memory control module is supplied on
two circuits. Circuit F35 provides a constant battery feed.
This circuit is protected by a 30 amp circuit breaker
located under the drivers seat. Power for the F35 circuit
is supplied on circuit A2. The A2 circuit is HOT at all
times and protected by a 40 amp fuse located in cavity 2
of the Power Distribution Center (PDC).
The M1 circuit also supplies battery voltage to the
control module. This circuit is the Ignition-Off Draw
(IOD) circuit, and protected by a 10 amp fuse located
in cavity 10 of the PDC.
Ground for the control module is supplied on circuit Z1. This circuit terminates at the instrument
panel left side cowl.
The control module supplies the power for the
power seat switch on circuit P9. This circuit feeds a
bus bar internal to the switch. Ground for the switch
is supplied on circuit Z1 and terminates at the
instrument panel left side cowl.
When the operator CLOSES a switch, contacts in
the switch CLOSE connecting the switch to the control module. The control module receives this input
and operates the proper seat motor.
The following is a list of the circuits that connect from
the switch to the control module and their functions:
• P40- Recliner forward
• P48- Recliner rearward
• P19- Front up
• P21- Front down
• P11- Rear up
• P13- Rear down
• P15- Seat forward
• P17- Seat rearward
To operate the seat motor(s), the control module
supplies the power and ground. The following is a list
of the circuits that connect from the control module
to the seat motors:
• P119, P121- Seat front up and down
• P111, P113- Rear up and down
• P115, P117- Seat forward and rearward
• P41, P43- Recliner forward and rearward
SEAT POTENTIOMETERS
The power seat control module receives an input
on the seat position from the potentiometers located
near the seat motors. The control module supplies 5
volts to the potentiometers on circuit P29. The control module also supplies a ground path for the
potentiometers on circuit P28.
There are four potentiometers used in this system
and each supplies a different input to the control
module. Circuit P26 provides the input for the front
up/down motor. Circuit P27 is used for the rear
up/down motor.
Circuit P25 is used for the horizontal forward/rearward
motor. Circuit P47 is used for the recliner motor.
MEMORY SET SWITCH
The memory set switch is used for programming
the desired seat positions into the control modules
memory. There are three switches used, a set switch,
memory 1, and memory 2. Power for the switches is
supplied from the control module to the switches.
Ground for the switches is supplied on circuit Z1 and
terminates at the instrument panel left side cowl.
Circuit P22 is used for the SET switch. Circuit P23
is used for the memory switch 1, and circuit P24 is
used for the memory switch 2.
REMOTE KEYLESS ENTRY MODULE INPUT
The Remote Keyless Entry (RKE) module provides
an input to the control module to indicate when the
operator is unlocking the doors.
HELPFUL INFORMATION
• Check the 30 amp circuit breaker located under
the drivers seat
• Check the 40 amp fuse located in cavity 2 of the PDC
• Check the ground at the instrument panel left
side cowl
