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. page DIAGNOSIS AND TESTING INTERMITTENT AND POOR CONNECTIONS . . .

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. 8W - 01 - 2 8W - 01 GENERAL INFORMATION NS/GS DESCRIPTION AND OPERATION (Continued) 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 NEAR THE BATTERY. GASES ARE ALWAYS PRESENT IN AND AROUND THE BATTERY. WARNING: ALWAYS REMOVE RINGS, WATCHES, LOOSE HANGING JEWELRY, AND LOOSE CLOTHING. Fig. 2 Wire Color Code Chart 8W - 01 GENERAL INFORMATION NS/GS 8W - 01 - 3 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- 8W - 01 - 4 8W - 01 GENERAL INFORMATION DESCRIPTION AND OPERATION (Continued) Fig. 5 Symbol Identification NS/GS NS/GS 8W - 01 GENERAL INFORMATION 8W - 01 - 5 DESCRIPTION AND OPERATION (Continued) 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. Fig. 7 Shock Tower to Spring Minimum Clearance Area 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. NS/GS 8W - 01 GENERAL INFORMATION 8W - 01 - 7 DIAGNOSIS AND TESTING (Continued) Fig. 11 Testing for Continuity TESTING FOR A SHORT TO GROUND ON FUSES POWERING SEVERAL LOADS (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. 8W - 01 - 8 8W - 01 GENERAL INFORMATION SERVICE PROCEDURES WIRING REPAIR When replacing or repairing a wire, it is important that the correct gauge be used as shown in the wiring diagrams.

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 CHARGING SYSTEM (DIESEL) The charging system is an integral part of the battery and starter systems.

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 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.

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. page INSTRUMENT CLUSTER OPERATION LIFTGATE AJAR INDICATOR LAMP . . . LOW FUEL LAMP . . . . . . . . . . . . . . . .

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. 8W - 40 - 14 8W - 40 INSTRUMENT CLUSTER NS/GS 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. NS/GS 8W - 40 INSTRUMENT CLUSTER 8W - 40 - 15 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 8W - 41 HORN/CIGAR LIGHTER/POWER OUTLET NS/GS 8W - 41 - 1 8W-41 HORN/CIGAR LIGHTER/POWER OUTLET INDEX page SCHEMATICS AND DIAGRAMS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 DESCRIPTION AND OPERATION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 Component Body Control Module .

The fuse is HOT at all times, on circuit F62, and supplies voltage to the coil and to the contact side of the horn relay. When the operator presses the horn switch, a ground path is completed on the coil side of the horn relay through the switch, on circuit X3. The horn relay, located in the PDC, then CLOSES the relay contacts. Voltage is passed through the CLOSED relay contacts on circuit X2 to the horns. Grounding for the horns is on the Z1 circuit to the right cowl panel. On vehicles equipped with Vehicle Theft Security System (VTSS), the X3 circuit is spliced to the Body Control Module (BCM). For operation of the VTSS, refer to section 8W-39. HELPFUL INFORMATION • Check the 20 amp fuse in cavity 20 of the PDC • Press the horn switch and listen for the horn relay to click. A clicking relay indicates voltage is present up to the switch • Check for a good ground at the right cowl panel. CIGAR LIGHTER/POWER OUTLET The cigar lighter and/or power outlet(s) are powered by a relay located in the Power Distribution Center (PDC). Power for the coil side of the relay is supplied on circuit F1. This circuit is HOT in the ACCESSORY and RUN positions only and protected by a 6 amp Positive Temperature Coefficient (PTC) located in PTC cavity 7 of the junction block. Circuit A31 is used to connect the PTC to the ignition switch. Battery voltage for the A31 circuit is supplied on circuit A1. This circuit is protected by a 40 amp fuse located in cavity 5 of the Power Distribution Center (PDC). Ground for the coil side of the relay is supplied on circuit Z1. This circuit terminated at the left cowl panel. When the ignition switch is in the ACCESSORY or RUN position, voltage flowing through the relay coil causes the contacts in the relay to CLOSE connecting circuits #6 and F30. Circuit #6 is protected by a 20 amp fuse located in cavity 21 of the PDC. Circuit F30 connects from the relay to the cigar lighter(s)/power outlet(s). Ground for the cigar lighter(s)/power outlet(s) is supplied on circuit Z1. CIGAR LIGHTER When the operator presses the lighter, the contacts inside of the lighter element CLOSE, and voltage flows through the heating element to ground. HELPFUL INFORMATION • Check the 40 amp fuse located in cavity 5 of the PDC • Check the 6 amp PTC located in PTC cavity 9 of the junction block. • Check the 25 amp fuse located in cavity 21 of the PDC • Check the cigar lighter element NS/GS 8W - 42 AIR CONDITIONING-HEATER 8W - 42 - 1 8W-42 AIR CONDITIONING-HEATER INDEX page SCHEMATICS AND DIAGRAMS . . . . . . . . . . . . . . . . . . . . . . . . . .

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.

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.

RADIATOR FAN OPERATION 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).

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 NS/GS 8W - 44 INTERIOR LIGHTING 8W - 44 - 1 8W-44 INTERIOR LIGHTING INDEX page SCHEMATICS AND DIAGRAMS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 1 DESCRIPTION AND OPERATION . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 Component Page A/C Heater Control . . . . . . . . . . . . . . . . . . . 8W-44-8 Ash Receiver Lamp . . . . . . . . . . . . . . . . . . . 8W-44-7 Automatic Day/Night Mirror . . . . . . . . . . . . 8W-44-6 Back-Up Lamp Switch . . . . . . . . . . . . . . . . 8W-44-6 Body Control Module . . . . . . 8W-44-2, 3, 4, 5, 7, 8, 9 Bs02 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-6 Bs10 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-2 Bs25 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-6 Compass/Mini-Trip Computer . . . . . . . . . 8W-44-6, 9 Courtesy Lamp Relay . . . . . . . . . . . . . 8W-44-2, 3, 4 Cs01 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-4 Cs02 . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-2, 3, 4 Cs03 . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-2, 3, 4 Cs04 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-6 Ds01 . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-3, 9 Front Blower Motor Relay . . . . . . . . . . . . . . 8W-44-6 Front Reading Lamp Defeat Switch . . . . . . 8W-44-2 Front Reading Lamps/Switch . . . . . . . . . 8W-44-2, 5 Fuse 1 (JB) . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-7 Fuse 4 (JB) . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-7 Fuse 6 (PDC) . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-7 Fuse 11 (PDC) . . . . . . . . . . . . . . . . . 8W-44-2, 3, 4, 5 Fuse 12 (JB) . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-6 G201 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-8 G300 . . . . . . . . . . . . . . . . . . . . . . 8W-44-3, 6, 7, 8, 9 G301 . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-5, 9 G302 . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-5, 9 G400 . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-4, 5 Glove Box Lamp . . . . . . . . . . . . . . . . . . . . . 8W-44-2 Headlamp Switch . . . . . . . . . . . . . . . . . . 8W-44-2, 7 Hood Ajar Switch . . . . . . . . . . . . . . . . . . . . 8W-44-5 Ignition Switch . . . . . . . . . . . . . . . . . . . . . . 8W-44-8 Instrument Cluster . . . . . . . . . . . . . . . . . . . 8W-44-8 Interior Lamps On Switch . . . . . . . . . . . . . . 8W-44-2 Junction Block . . . . . . . . . 8W-44-2, 3, 4, 5, 6, 7, 8, 9 Key-In Halo Lamp . . . . . . . . . . . . . . . . . . . . 8W-44-3 Left Door Arm/Disarm Key Cylinder Switch . . . . . . . . . . . . . . . . 8W-44-9 Component Page Left Door Courtesy Lamp . . . . . . . . . . . . . . 8W-44-3 Left Front Door Ajar Switch . . . . . . . . . . . . 8W-44-5 Left Liftgate Flood Lamp . . . . . . . . . . . . . . 8W-44-4 Left Mid Reading Lamp . . . . . . . . . . . . . . . 8W-44-4 Left Power Door Lock Switch . . . . . . . . . . . 8W-44-9 Left Power Window Switch . . . . . . . . . . . . . 8W-44-9 Left Rear Door Ajar Switch . . . . . . . . . . . . . 8W-44-5 Left Rear Reading Lamp . . . . . . . . . . . . . . . 8W-44-4 Left Repeater Lamp . . . . . . . . . . . . . . . . . . 8W-44-6 Left Visor/Vanity Mirror Lamps . . . . . . . . . 8W-44-3 Liftgate Ajar Switch . . . . . . . . . . . . . . . . . . 8W-44-5 Message Center . . . . . . . . . . . . . . . . . . . . . . 8W-44-7 Park Lamp Relay . . . . . . . . . . . . . . . . . . . . 8W-44-7 Power Distribution Center . . . . . . 8W-44-2, 3, 4, 5, 7 Power Folding Mirror Switch . . . . . . . . . . . 8W-44-3 Power Mirror Switch . . . . . . . . . . . . . . . . . . 8W-44-8 Radio . . . . . . . . . . . . . . . . . . . . . . . . . . . . 8W-44-7, 8 Rear Blower Front Control Switch . . . . . . . 8W-44-8 Rear Blower Rear Control Switch . . . . . . . . 8W-44-9 Right Door Arm/Disarm Key Cylinder Switch . . . . . . . . . . . . . . . . 8W-44-9 Right Door Courtesy Lamp . . . . . . . . . . . 8W-44-3, 9 Right Front Door Ajar Switch . . . . . . . . . . . 8W-44-5 Right Liftgate Flood Lamp . . . . . . . . . . . . . 8W-44-4 Right Mid Reading Lamp . . . . . . . . . . . . . . 8W-44-4 Right Power Door Lock Switch . . . . . . . . . . 8W-44-9 Right Power Window Switch . . . . . . . . . . 8W-44-3, 9 Right Rear Door Ajar Switch . . . . . . . . . . . . 8W-44-5 Right Rear Reading Lamp . . . . . . . . . . . . . . 8W-44-4 Right Visor/Vanity Mirror Lamps . . . . . . . . 8W-44-3 Traction Control Switch . . . . . . . . . . . . . . . 8W-44-8 Transmission Range Sensor . . . . . . . . . . . . 8W-44-6 Underhood Lamps . . . . . . . . . . . . . . . . . . . . 8W-44-5 Wiper Module . . . . . . . . . . . . . . . . . 8W-44-2, 3, 4, 5 8W -

HELPFUL INFORMATION . . . . . . . . . . . . . . . . . 10 10 11 11 10 10 11 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 (-). page ILLUMINATED ENTRY . . . . . . . . . . . . . . . . . . . . INTRODUCITON . . . . . . . . . . . . . . . . . . . . . . . .

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. NS/GS 8W - 45 BODY CONTROL MODULE 8W - 45 - 11 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.

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. Power for the deicer is supplied on circuit F30. This circuit is HOT at all times and protected by a 20 amp fuse located in cavity 21 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. page LOW WASHER FLUID LAMP REAR (LIFTGATE) WIPER . .

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. 8W - 53 - 6 8W - 53 WIPERS NS/GS 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.

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). 8W - 61 - 8 8W - 61 POWER DOOR LOCKS 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.

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 - 8 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.
