Instrument Cluster Test

In order to diagnose the instrument cluster function, a DRB III scan tool and the proper Body Diagnostic Procedures are required.

As a quick diagnosis, the cluster will perform a function check immediately after the ignition is switched to the RUN/START position. The electronic display, odometer and transmission range indicator and all warning lamps except:
- High beam
- Turn signal
will illuminate for a brief period.

If the cluster is not receiving CCD bus messages, the cluster will appear nonfunctional except for the continuously illuminated airbag and CHECK gauges indicators and NO BUS message displayed.

If the cluster is not receiving CCD bus messages, refer to the pre-diagnostic test described in proper Body Diagnostic Procedures or refer to the Instrument Cluster Self-Diagnostic Test below.
