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.
- Verify the customer concern by operating the system.
- Visually inspect for obvious signs of mechanical or electrical damage.
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the concern remains after the inspection connect the New Generation STAR (NGS) Tester to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from NGS Tester menu. If NGS Tester 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 NGS Tester still does not communicate with the vehicle, refer to the New Generation STAR (NGS) Tester manual.
- Carry out the DATA LINK DIAGNOSTICS test. If the NGS Tester responds with:
- CKT 914, CKT 915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, see MODULE COMMUNICATIONS NETWORK - LS .
- NO RESP/NOT EQUIP for DSM, GO to PINPOINT TEST A .
- NO RESP/NOT EQUIP for DDM, GO to PINPOINT TEST B .
- System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self test diagnostics for the DSM and the DDM.
- If the DSM DTCs retrieved are related to the concern, go to the DSM DIAGNOSTIC TROUBLE CODE (DTC) INDEX .
- If the DDM DTCs retrieved are related to the concern, go to the DDM DIAGNOSTIC TROUBLE CODE (DTC) INDEX .
- If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue the diagnostics.
