Inspection and Verification
WARNING: This page is about a different car, the 2002 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The FEM and instrument cluster must be reconfigured upon replacement. See MODULE CONFIGURATION
.
- Verify the customer concern by operating the horn.
- Visually inspect for obvious signs of mechanical and electrical damage.
- 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 DIAGNOSTIC TEST. If the diagnostic tool responds with:
- CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, MULTIFUNCTION ELECTRONIC CONTROL MODULES .
- NO RESP/NOT EQUIP for instrument cluster, GO to PINPOINT TEST B .
- NO RESP/NOT EQUIP for FEM, GO to PINPOINT TEST A .
- SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the instrument cluster and FEM.
- If the DTCs retrieved are related to the concern, go to the INSTRUMENT CLUSTER DIAGNOSTIC TROUBLE CODE (DTC) INDEX or go to the FEM DIAGNOSTIC TROUBLE CODE (DTC) INDEX to continue diagnostics.
- If no DTCs related to the concern are retrieved, proceed to SYMPTOM CHART to continue diagnostics.
