Inspection and Verification

INSPECTION AND VERIFICATION

1. Verify the customer concern.

Visual Inspection Chart:

2. Visually inspect for obvious signs of mechanical or electrical damage.
3. If the cause is not visually evident, 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) 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 operating manual.
6. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- CAN 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 SJB, refer to Body Control Systems (Multifunction Electronic Control Module).
- No response/not equipped for the PCM, refer to Information Bus (Module Communications Network).
- No response/not equipped for the RCM, refer to Air Bag Systems.
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the 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, the Smart Junction Box (SJB) Diagnostic Trouble Code (DTC) Index, or the Powertrain Control Module (PCM) Diagnostic Trouble Code (DTC) Index.
