Initial Inspection - Instrument Cluster

1. Verify the customer concern by operating the system.
2. Visually inspect for obvious signs of mechanical or electrical damage.







VISUAL INSPECTION CHART

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. Verify the following systems are working correctly:
- charging
- fuel
- cooling
- safety belt warning chime (GEM)
- turn signals
- headlamps
- anti-lock brake system/traction control

If the system(s) is not working correctly, refer to appropriate system.

5. If the concern remains after the inspection, connect the scan tool to the data link connector located beneath the instrument panel and select the vehicle to be tested from the scan tool menu. If the scan 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.

6. If the scan tool still does not communicate with the vehicle, refer to the scan tool manual.
7. Carry out the DATA LINK DIAGNOSTIC TEST. If the scan tool responds with:
- CKT 914, CKT 915 or CKT 70 = ALL ECUS NO RES/NOT EQUIP, refer to Module Communications Network (Information Bus).
- NO RESP/NOT EQUIP for Generic Electronic Module (GEM), refer to Multifunction Electronic Control Module.
- SYSTEM PASSED, retrieve and record the continuous DTCs, erase the continuous DTCs and carry out self-test diagnostics for the GEM.

8. If the DTCs retrieved are related to the concern, go to the GEM DTC Index to continue diagnostics. Refer to Multifunction Electronic Control Module. Trouble Code Diagnostic Charts - Instrument Cluster
9. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics. Diagnosis By Symptom - Instrument Cluster
