Inspection and Verification

NOTE: The LCM must be reconfigured upon installation. Refer to MODULE COMMUNICATIONS NETWORK .

Visually inspect for obvious signs of mechanical and electrical damage.

VISUAL INSPECTION CHART

Mechanical	Electrical
Door ajar switches	Central junction box (CJB) fuses: 6 (15A) 15 (15A) 21 (15A) 23 (15A) 27 (20A) Battery junction box (BJB) fuses: 8 (30A) Circuitry Miniature bulbs Connectors Interior lamps Lighting control module (LCM)

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 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 DATA LINK DIAGNOSTICS TEST. If the diagnostic tool responds with:
- CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to MODULE COMMUNICATIONS NETWORK .
- NO RESP/NOT EQUIP for LCM, refer to MODULE COMMUNICATIONS NETWORK .
- NO RESP/NOT EQUIP for DDM, 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 diagnostics for the LCM and DDM modules.
If the DTCs retrieved are related to the concern, go to the LCM or DDM Diagnostic Trouble Code (DTC) Index to continue diagnostics.
If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.
