OPERATION

FASTEN SEAT BELT

The seat belt reminder system uses both visual
and audible signals. The Instrument Cluster moni­tors the driver seat belt buckle switch. When the
ignition switch transitions from OFF to RUN and the
driver seat belt has not been buckled, the Instrument
Cluster will illuminate the seat belt indicator lamp
and sound the chime. The system will always illumi­nate the seat belt reminder lamp for four to eight
seconds when the ignition switch is turned to the ON
position. The CHIME will sound during the same
time interval if the driver’s seat belt is not fastened.
The warning lamp will remain illuminated as long as
the seat belt remains unbuckled, and the ignition
switch is in the RUN position. Passenger seat belts
are not connected to the system.

DIAGNOSIS AND TESTING - CHIME

CONDITIONS ..........................2

lamp or headlamp position, the chime will sound
until the headlamp switch is turned off, the door is
closed or the battery protection time out expires.

KEY IN IGNITION REMINDER

The Instrument Cluster monitors the ignition
switch. The chime will activate if the drivers door is
opened and the key is in the ignition switch, with the
ignition switch in either the OFF, LOCK, or the
accessory (ACC) position. The chime will continue
until the key is removed from the ignition switch or
the door is closed.

DOOR AJAR CHIME

The Instrument Cluster monitors the door ajar
switches. A chime will sound once when the door is
opened, the ignition is in RUN position and vehicle
speed is present.

TURN SIGNAL ON

The Instrument Cluster monitors the multiplex
multifunction switch. The instrument cluster shall
remind the driver that either turn signal has been
left on by a continuous chime after the turn signal
indicator is left ON for 1.0 miles and the vehicle
speed is 15 mph or greater.

LOW FUEL REMINDER

When the fuel level drops to approximately 1/8
tank, the fuel symbol will light and a single chime
will sound. The light will remain on until fuel is
added.

OVER SPEED

During any ignition ON, the Instrument Cluster
maintains the most recently received speed. If the
vehicle speed exceeds a preprogramed limit set in the
instrument cluster it will activate a single chime.

HEADLAMPS REMINDER

The Instrument Cluster monitors the multiplex
headlamp switch. The headlamp audible warning will
alert the driver that the exterior lamps have been
left on. If the ignition switch is left off, the driver’s
door open, and the headlamp switch is in the park

WARNING LAMP ANNOUNCEMENT

The Instrument Cluster monitors critical engine
and transmission system parameters. If any of the
systems are out of their operating parameters, the
instrument cluster will illuminate a lamp and acti­vate and audible chime.

LOW WASH INDICATOR

The Front Control Module (FCM) monitors the
washer reservoir. When the fluid is low the FCM
transmits a J1850 message over the bus. The instru­ment cluster will chime and illuminate the LOW
WASH indicator. The indicator will remain on until
the fluid level is corrected.

AIR BAG

The Instrument Cluster monitors air bag system
via the J1850 bus communications from the air bag
module. The air bag module will transmit a message
once per second, over the J1850 bus, as to whether
the warning indicator should be on or off. The warn­ing indicator indicates a part of the air bag system is
inoperative and needs to be serviced. It does not
indicate that the air bag system will not deploy. If
the instrument cluster does not receive a message
from the air bag module for 3 consecutive seconds,
the Instrument will illuminate the warning indicator.

The air bag module transmits a J1850 message
requesting the instrument cluster to perform a bulb
check each time the ignition is turned to the on posi­tion

Visually inspect the related wiring harness connec­tors. Look for broken, bent, pushed out, or corroded
terminals. If any of the conditions are present, repair
as necessary. If not use the DRBIIIt scan tool and
the proper Body Diagnostic Procedure manual. For
complete circuit diagrams, refer to Instrument
