Component Tests and General Diagnostics

INSTRUMENT CLUSTER WARNING/INDICATOR LAMPS TEST
Every time the vehicle is switched to the START/RUN position, the cluster goes through a BULB CHECK. This tests most of the indicator lamps and Vacuum Fluorescent (VF) displays. If any of the lamps fail to light during the bulb check, refer to the proper Body Diagnostic Procedures. The lamps are not replaceable except for the high beam indicator and gauge illumination bulbs. Non of these though will illuminate, along with the security indicator, during the bulb check at initial KEY ON.

To diagnose the cluster lamps first place the cluster in self-diagnostic mode. With the ignition switch in the OFF position, press the trip odometer reset button down. Simultaneously turn the ignition key to the ON position and release the trip reset button. All the indicator lamps and VF displays should illuminate except for the fog lamp and liftgate ajar.
