Reading and Clearing Diagnostic Trouble Codes

NOTE: Ford DOES NOT provide procedures to retrieve or clear trouble codes without the New Generation Star (NGS) tester.

NOTE: A scan tool MUST be used to diagnose the ABS system. There is NO provision for flashout of DTCs.

1. 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 the NGS menu. If the NGS does not communicate with the vehicle:
- check that the program card is properly installed.
- check the connections to the vehicle.
- check the ignition switch position.

2. If the NGS still does not communicate with the vehicle, refer to the New Generation STAR Tester manual.
3. Perform the DATA LINK DIAGNOSTIC TEST. If the NGS responds with:
- CKT9 14, CKT9 15, or CKT70 = ALL ECUS NO RESP/NOT EQUIP, diagnose the communications network.
- NO RESP/NOT EQUIP for anti-lock brake control module, go to Pinpoint Test F.
- SYSTEM PASSED, retrieve and record the continuous Diagnostic Trouble Codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the anti-lock brake control module.

4. If the DTCs retrieved are related to the concern, go to Anti-Lock Brake Control Module Diagnostic Trouble Code (DTC) Index to continue diagnostics.
5. If no DTCs related to the concern are retrieved, proceed to Symptom Chart. Symptom Related Diagnostic Procedures
