Instrument Cluster / Carrier: Testing and Inspection

ELECTRONIC VEHICLE INFORMATION CENTER

1. Remove the instrument cluster. Check for battery voltage at the fused B(+) circuit cavity of the cluster. If OK, go to STEP 2. If not OK, repair the open fused B(+) circuit as required.
2. Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Check for continuity between the ground circuit cavity of the cluster and a good ground. There should be continuity. If OK, go to STEP 3. If not OK, repair the open ground circuit as required.
3. Connect negative battery cable. Turn the ignition switch to the On position. Check for battery voltage at the fused ignition switch output (run/start) circuit cavity of the cluster. If OK, the voltage and ground supply to the cluster is OK at this time. If not OK, repair the open fused ignition switch output (run/start) circuit as required.
