Instrument Cluster Inoperative

INSTRUMENT CLUSTER INOPERATIVE

DIAGNOSTIC FAULT INFORMATION
Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview

CIRCUIT/SYSTEM DESCRIPTION
Voltage is supplied to the instrument panel cluster (IPC) through the battery voltage circuit and the ignition 1 voltage circuit. The IPC will operate when the ignition 1 voltage circuit is 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 ignition 1 voltage circuit and a ground.
- If the test lamp does not illuminate, repair the ignition 1 voltage circuit for a short to ground or an open/high resistance.
3. Verify that a test lamp illuminates between the ignition 1 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

REPAIR INSTRUCTIONS
Perform the Diagnostic Repair Verification after completing the diagnostic procedure. Verification Tests
