- If inspection reveals an obvious concern that is readily repaired, correct the concern before continuing with Inspection and Verification.
- If the concern remains after inspection, connect the diagnostic tool to the data link connector (DLC) located beneath the instrument panel to carries out DATA LINK DIAGNOSTICS (DTC) test. If the diagnostic tool responds with NO RESPONSE/NOT EQUIPPED for the lighting control module (LCM), refer to MODULE COMMUNICATIONS NETWORK . If the DATA LINK DIAGNOSTICS test is passed for the LCM, retrieve continuous DTCs and execute self test diagnostics for the LCM to retrieve current DTCs.
- If the self-test is passed and no DTCs are retrieved, go to the SYMPTOM CHART to continue diagnostics.
- If DTCs are retrieved, go to the LIGHTING CONTROL MODULE (LCM) DIAGNOSTIC TROUBLE CODE (DTC) INDEX to continue diagnostics.
- If the LCM cannot be accessed by the diagnostic tool, refer to MODULE COMMUNICATIONS NETWORK .
