Perform the Diagnostic System Check - Vehicle , prior to using this diagnostic procedure.

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

1. Ignition OFF, disconnect the instrument panel cluster (IPC).
2. Ignition ON, verify that a test lamp illuminates between the ignition voltage circuit and a known ground.

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

3. Verify that a test lamp illuminates between the ignition voltage circuit and the IPC ground circuit.

⇒	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

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
