Instrument Cluster Inoperative

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle (Diagnostic System Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (Strategy Based Diagnosis) for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions (Diagnostic Procedure Instructions) provides an overview of each diagnostic category.



Circuit/System Description

Voltage is supplied to the instrument panel cluster (IPC) through the battery voltage circuit and the RUN/CRANK relay voltage circuit. The IPC will operate when the RUN/CRANK relay voltage circuit is commanded on in the RUN/START position.

Circuit/System Testing

1. Ignition OFF, disconnect the IPC.
2. Ignition ON, verify that a test lamp illuminates between the RUN/CRANK relay voltage circuit terminal 5 and a ground.

• If the test lamp does not illuminate, repair the RUN/CRANK voltage circuit for a short to ground or an open/high resistance.

3. Verify that a test lamp illuminates between the RUN/CRANK relay voltage circuit terminal 5 and the IPC ground circuit terminal 13.

• If the test lamp does not illuminate, repair the IPC ground circuit for an open/high resistance.

4. If all circuits test normal, replace the IPC.



Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
