Diagnostic Aids

For diagnosis of the Instrument Panel, perform the System Check in the Instrument Panel Cluster.

Check for the following conditions:

^ Poor connection at PCM or Generator. Inspect harness connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, and poor terminal to wire connection.

^ Damaged harness. Inspect the wiring harness for damage. If the harness appears to be OK, disconnect the PCM and turn the ignition ON. Observe a voltmeter connected to the affected PCM circuit while moving connectors and wiring harnesses related to the PCM circuit. A change in voltage will indicate the location of the fault.
