NOTE: For multifunction switch concerns, refer to one of the following sections:- Exterior Lighting, refer to EXTERIOR LIGHTING article .
- Wipers and Washers, refer to BODY SYSTEM - EXTERIOR article .
- 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 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 manual.
- Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
- SCP or UBP circuit fault; all electronic control units no response/not equipped, refer to MODULE COMMUNICATIONS NETWORK article .
- No response/not equipped for instrument cluster, go to INFORMATION GAUGES AND WARNING DEVICES .
- 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.
- If the DTCs retrieved are related to the concern, go to the INSTRUMENT CLUSTER DIAGNOSTIC TROUBLE CODE INDEX table to continue diagnostics.
- If no DTCs related to the concern are retrieved, GO to SYMPTOM CHART to continue diagnostics.
