CLEANING AND INSPECTION
HEADLAMP CLEANING
This vehicle is equipped with plastic headlights
that are lighter and less susceptible to stone break-
age than glass headlights.
This plastic is not as scratch resistant as glass and
therefore a different lens cleaning procedures must
be followed.
To minimize the possibility of scratching the lenses
and reducing light output, avoid wiping with a dry
cloth. To remove road dirt, wash with a mild soap
solution followed by rinsing with water.
Do not use abrasive cleaning components, solvents,
steel wool or other aggressive material to clean the
lenses.

NSCHIME WARNING/REMINDER SYSTEM 8U - 1
(2) Inspect BCM connectors and wires for proper
connection. If OK, replace BCM for tone condition.
DOME LAMP ON CHIME
The dome lamp on chime will warn the driver that
the dome lamps have been left on.
With the ignition is OFF:
²Driver's door OPEN (door ajar switch is closed to
ground)
²Dome lamps are ON (dome lamp switch is closed
to ground),
The chime will sound continuously until driver's
door is closed, dome lamps tuned OFF or until the
battery protection time out of 15 minutes has
expired. Refer Group 8L, Lamps proper procedures.
Chime rate: 168 to 192 chimes per minute.
ENGINE TEMPERATURE CRITICAL CHIME
The engine temperature critical chime will warn
the driver that the vehicle's engine is overheating.
While monitoring the coolant temperature, the Pow-
ertrain Control Module (PCM) will send on the CCD
bus as engine temperature every 1.376 seconds to the
Body Control Module (BCM). The BCM calculates
engine temperature and determines if a warning
should occur. This feature is functional only with the
Ignition Switch in the Run/Start position.
When the engine temperature reaches 122ÉC
(252ÉF) the BCM will chime one tone and the engine
temperature lamp comes ON. The BCM turns OFF
the lamp when the engine temperature reaches
117ÉC (242ÉF). The BCM will chime continuously
when the engine temperature reaches 125ÉC (257ÉF).
The chime will turn OFF after four minutes or when
the temperature reaches 117ÉC (242ÉF), which ever
occurs first.
EXTERIOR LAMPS ON CHIME
The exterior lamp on chime will warn the driver
that the exterior lights have been left on.
With the ignition switch OFF:
²Driver's door is open (door ajar switch is closed
to ground)
²Parking lamps or headlamps ON (parking lamp
switch is closed to ground)
The chime will sound until lights are turned OFF,
driver's door closed or until the battery protection
time out of 3 minutes has expired.
Refer to Group 8L, Lamps, for proper service pro-
cedures. Chime rate: 168 to 192 chimes per minute.
To test the exterior lamps left on function:
²Turn ignition off
²Remove ignition key
²Turn exterior lamps on with driver's door open.
Chime should sound until lamps are turned off or
driver's door is closed.
KEY-IN IGNITION CHIME
The key-in ignition chime will act as a warning to
the driver that the ignition key has been left in the
ignition switch.
With the ignition switch is in OFF position ONLY:
²Driver's door is open/ajar (door ajar switch is
closed to ground)
²Key is in the ignition switch (key-in ignition
switch is closed to ground)
The chime will sound until one of the above condi-
tions is removed. Chime rate: 168 to 192 chimes per
minute.
To test the key-in ignition function, insert key into
the ignition and open driver's door. Do not turn igni-
tion ON. Chime should sound until key is removed
from ignition or driver's door is closed.
LOW OIL PRESSURE CHIME OPERATION
The low oil pressure chime will warn the driver
that the engine oil pressure is low. The oil pressure
switch, will close to ground during a low oil pressure
condition. The oil pressure lamp will illuminate in
the message center. The body control module will
monitor the oil pressure switch and signal a low oil
pressure condition. A continuous four minute warn-
ing chime will sound and the oil pressure lamp will
come ON when the following conditions are met:
²Ignition on and engine not cranking
²Engine running at 420 to 480 rpm for 10 sec-
onds
²Oil pressure switch closed to ground for (1 sec-
ond minimum, 2 seconds maximum)
Chime rate: 168 to 192 chimes per minute.
SEAT BELT CHIME
The seat belt chime will sound for 4 to 8 seconds,
when the ignition is turned on and the driver's seat
belt is not buckled (seat belt switch is closed to
ground). This is a reminder to the driver to buckle
the seat belt. The seat belt lamp is controlled by the
mechanical instrument cluster. The cluster will also
illuminate the seat belt warning lamp for 6 seconds.
Buckling the driver's seat belt before the time out
has expired will cause the chime to stop immediately.
Chime rate: 38 to 62 chimes per minute.
To test the seat belt warning system, the ignition
switch must be in the OFF position for 1 minute
before starting the test. Turn the ignition switch to
the on position with the driver's seat belt not buck-
led. The seat belt warning lamp should light and the
chime should sound 4 to 8 seconds.
