Instrument Cluster Inoperative
Instrument Cluster Inoperative
Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview
* Review Strategy Based Diagnosis for an overview of the diagnostic approach.
* 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
