INSPECTION AND VERIFICATION

1. Verify the customer concern.

Visual Inspection Chart:

2. Visually inspect for obvious signs of mechanical or electrical damage.
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. If the cause is not visually evident, connect the diagnostic tool to the data link connector 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 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 operating manual.
6. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- CAN or ISO circuit fault; all electronic control units no response/not equipped, refer to Information Bus (Module Communications Network).
- No response/not equipped for the instrument cluster, GO to Pinpoint Test A. Test A: No Communication With the Instrument Cluster
- No response/not equipped for the restraint control module (RCM), refer to Air Bag Systems.
- 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 or the Restraint Control Module (RCM) Diagnostic Trouble Code (DTC) Index. Instrument Cluster Diagnostic Trouble Code (DTC) Index Restraint Control Module (RCM) DTC Index
8. If no DTCs related to the concern are retrieved, GO to Symptom Chart. Diagnosis By Symptom - Instrument Cluster
