Initial Inspection - Instrument Cluster

1. Verify the customer concern by operating the instrument cluster to duplicate the condition by observing the indicators, warning displays, and gauges to determine if they are operating correctly with the ignition switch:
- in RUN with the engine off.
- in START before the ignition switch is released.
- in RUN with the engine running.

2. Visually inspect for obvious signs of mechanical and electrical damage; refer to the chart.

Visual Inspection Chart:

3. If the inspection reveals obvious concern(s) that can be readily identified, repair as necessary.
4. If the concern remains after the inspection, connect the diagnostic tool to the Data Link Connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
- check that the program card is correctly installed.
- check the connections to the vehicle.
- check the ignition switch position.
5. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool manual.
6. Carry out the DATA LINK DIAGNOSTIC TEST. Pinpoint Test PC (Precheck)
If the diagnostic tool responds with:
- CKT914, CKT915 or CKT70 ALL ECUS NO RESP/NOT EQUIP, refer to Module Communications Network (Information Bus).
- NO RESP/NOT EQUIP for instrument cluster, go to Pinpoint Test A. Test A: No Communication With the Module-Unable to Perform On-Demand Self-on Lighting Control Module
- SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the instrument cluster.
7. If the DTCs retrieved are related to the concern, go to the instrument cluster Diagnostic Trouble Code (DTC) Index to continue diagnostics. For Lighting Control Module (LCM) concerns, refer to Multifunction Electronic Control Module (General Module) for a complete DTC index. Trouble Code Diagnostic Charts - Instrument Cluster
8. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics. Diagnosis By Symptom - Instrument Cluster
