Inspection and Verification
WARNING: This page is about a different car, the 2003 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
- Verify the customer concern by operating the interior lighting system.
- Visually inspect for the following obvious signs of mechanical and electrical damage.
NOTE: A newly installed LCM must be reconfigured. Refer to the diagnostic tool help screen on the configuration card to program the 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, see MODULE COMMUNICATIONS NETWORK .
- NO RESP/NOT EQUIP for lighting control module (LCM), see MULTIFUNCTION ELECTRONIC CONTROL MODULES .
- NO RESP/NOT EQUIP for driver door module (DDM), see MULTIFUNCTION ELECTRONIC CONTROL MODULES .
- SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out the self-test diagnostics for the LCM and DDM.
- If the DTCs retrieved are related to the concern, go to the LCM DIAGNOSTIC TROUBLE CODE (DTC) INDEX or the 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.
