Inspection and Verification
NOTE:
The instrument cluster and the front electronic module (FEM) must be reconfigured upon installation. Refer to
MODULE COMMUNICATIONS NETWORK
.
- Verify the customer concern.
- Visually inspect for obvious signs of mechanical and electrical damage.
Visual Inspection Chart
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select 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.
- If the diagnostic tool still does not communicate with the vehicle, Refer to the diagnostic tool operating manual.
- Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- SCP+ or SCP- circuit fault; all electronic control units no response/not equipped, Refer to MODULE COMMUNICATIONS NETWORK .
- No response/not equipped for the instrument cluster, GO to Figure.
- No response/not equipped for the FEM, Refer to MODULE COMMUNICATIONS NETWORK .
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs) erase the continuous DTCs and carry out self-test diagnostic for the instrument cluster and FEM.
- If the DTCs retrieved are related to the concern, Refer to MODULE COMMUNICATIONS NETWORK to continue diagnostics.
- If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART to continue diagnostics.
