DIAGNOSIS AND TESTING

INSTRUMENT CLUSTER

As a quick diagnosis, the cluster will perform a functional check of the odometer display, transmission range display and warning indicators after the ignition is switched to RUN/START. If the cluster is not receiving any bus messages, the cluster will appear non-functional and "no bus" will appear in the odometer display.

A self-test of the cluster can also be initiated by pressing and holding the odometer reset button and switching the ignition from lock to unlock. The cluster will then step through several displays for functional verification.

By pressing the trip odometer reset button while going through the self-test, you can temporarily freeze the test.

Pressing the bottom again will continue sequence. The cluster will store bus communication faults with other modules. It will also store faults for the AIRBAG and ABS lamps. During the self-diagnostics, the AIRBAG and ABS lamps are tested.

If the cluster is not functioning properly, refer to BODY article.

If the cluster is not receiving bus messages, refer to BODY article.

In order to diagnose the instrument cluster functions, a scan tool and the proper Body Diagnostic article are required.

If the diagnostic procedure determines that a replacement of an instrument cluster component is required, refer to Removal and Installation .

REMOVAL

Fig. 2: Instrument Cluster

1. Disconnect and isolate the battery negative cable.

NOTE: The left hand side of the instrument cluster trim bezel is under the AC vent on the inboard side. When removing the instrument cluster trim bezel, it may be necessary to flex the AC vent slightly to relieve the bezel from under the AC vent.

2. Remove the instrument cluster trim bezel using a trim stick or equivalent and gently prying at point (1).

NOTE: When installing the cluster trim bezel, be sure to place the left hand side of the bezel underneath the AC vent. It may be necessary to flex the trim on the AC vent slightly to allow the cluster trim bezel locking clips secure entry into the instrument panel.

3. Install the cluster trim bezel.

4. Connect the battery negative cable.
