Issued: June 2007
IMPORTANCE OF PROPER SET-UP AND PRE-DELIVERY SERVICE
FOR YOUR CUSTOMER'S SAFETY
Proper set-up and pre-delivery service are essential to rider safety and the reliability of the
machine. Any error or oversight made by the technician assembling and servicing a new machine
can result in faulty operation, damage to the machine, or injury to the rider.
WARNING
Improper set-up or pre-delivery service can
create an unsafe condition that can cause
your customer to be seriously hurt or killed.
Follow the procedures and precautions in
this manual and the Service Manual carefully.
FOR YOUR SAFETY
Some of the most important safety precautions are given below. However, we cannot warn you
of every conceivable hazard that can arise in performing set-up and pre-delivery service. Only
you can decide whether or not you should perform a given task.
WARNING
Failure to properly follow instructions and
precautions can cause you to be seriously
hurt or killed.
Follow the procedures and precautions in this
manual carefully.
IMPORTANT SAFETY PRECAUTIONS
Make sure you have a clear understanding of all basic shop safety practices and that you are
wearing appropriate clothing and safety equipment. When performing the set-up or pre-delivery
service, be especially careful of the following:
• Read the instructions before you begin, and make sure you have the tools and skills required to
perform the tasks safely.
• To prevent the machine from falling on you, park it on a firm, level surface, using the proper
stand(s) to provide firm support.
Make sure the engine is off before you begin any servicing procedures. This will help eliminate
several potential hazards:
• Carbon monoxide poisoning from engine exhaust—be sure there is adequate ventilation
whenever you run the engine.
• Burns from hot parts—let the engine and exhaust system cool before touching.
• Injury from moving parts—do not run the engine unless the instruction tells you to do so.
Even then, keep your hands, fingers, and clothing away.
To reduce the possibility of a fire or explosion, be careful when working around gasoline or
batteries. Use only a nonflammable solvent, not gasoline, to clean parts. Keep all cigarettes,
sparks and flames away from the battery and all fuel-related parts.

18. Initialize the ECM.
The GL 1800 uses an electronically controlled
IAC (Idle Air Control Valve) to minimize idle
fluctuations normally caused by air
temperature and load variations.
In order for the IAC to operate properly, the
ECM (Engine Control Module) must be
initialized.
Start the engine and let it warm up to normal
operating temperature.
Idle Speed: 700 ± 70 rpm
Once normal temperature is achieved, allow
the engine to idle, without touching the
throttle, for at least 90 seconds. If the throttle
is operated during this time, the ECM will not
initialize properly and the process will need to
be repeated. Idle speed should stabilize at
700 ± 70 rpm.
19. Check the seat and handlebar grip
heaters (all models except IIIA).
Turn the front and rear seat heater and
handlebar grip heater dials to MAX.
Start the engine and let it idle for
3 – 4 minutes.
Check that the front and rear seats, passenger
backrest, and both the handlebar grips
become warm.
If the seats and passenger backrest do not
heat up, recheck the seat and backrest heater
connections to the wire harness by referring
to steps 6 and 10.

20. Initialize the Navigation System and
set the correct time zone (cont.).
Set time zone:
The clock on the Navigation System receives
universal time information from the GPS
satellites. However, the time zone where the
motorcycle is located must be entered for the
clock to indicate the correct local time.
The time zone default is Eastern. If you are in
a different time zone, you will need to change
the zone in the system.
From the SETUP/SYSTEM number 1 window,
scroll down to Time Zone and press ENT.
Scroll down to the correct local time zone and
press ENT.
The clock will automatically correct to the
local time.
Stop the engine and turn off the ignition.
For setting the correct time on the nonNavigation equipped models, refer to the
Owner’s Manual.
21. Check the airbag indicator light
(Airbag model only).

airbag indicator light comes on for six
seconds then goes off. If the indicator light
does not come on or stays on refer to the
Service Manual.

23. Check the clutch lever and sidestand
ignition cut-off switches.
When the transmission is in gear, the starter
should not work unless the clutch lever is
pulled in and the sidestand is up.
Position the motorcycle securely with the rear
wheel raised off the ground.

Shift the transmission into gear.
Raise the sidestand and without pulling the
clutch lever in, turn on the ignition, set the
engine stop switch to the RUN position, and
press the starter button.
If the engine starts, there is a problem with
the clutch lever ignition cut-off switch.
Troubleshoot the cause.
Sidestand ignition cut-off switch test:
Shift the transmission into gear.
Lower the sidestand and pull the clutch lever
in. Turn on the ignition, set the engine stop
switch to the RUN position, and press the
starter button.
If the engine starts, there is a problem with
the sidestand ignition cut-off switch.
Troubleshoot the cause.

available on iN) by checking the boxes
confirming the steps were done.
