INSPECTION AND VERIFICATION

1. Verify the customer concern by operating the system.

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 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 or disk 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 operating manual.
6. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- UBP, SCP 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. For vehicle security module, refer to Body Control Systems (Multifunction Electronic Control Module); for ABS, refer to Antilock Brake System or Traction Control System; or for restraint control module, refer to Air Bag Systems. Test A
- 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 Restraint Control Module Diagnostic Trouble Code (DTC) Index to continue diagnostics. 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
