Component Tests

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, turn signal indicators, and gauge illumination bulbs. None 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, turn signal, liftgate ajar, and high beam select indicators.
