Clearing Trouble Codes

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

To Retrieve/Clear Diagnostic Trouble Codes (DTCs), follow these steps:
1. Connect New Generation Star (NGS) Tester or equivalent to Data Link Connector (DLC).
2. Turn ignition switch to RUN position.
3. Select the MODEL YEAR and VEHICLE.
4. Select DIAGNOSTIC DATA LINK.
5. Select ECS.
6. Select DIAGNOSTIC TEST MODES.
7. Select RETRIEVE/CLEAR CONTINUOUS DTCs.
8. After pressing START, all continuous DTCs will be displayed on the screen. Before proceeding with the clearing operation, make note of DTCs displayed, because once cleared, they cannot be retrieved.
9. To clear DTCs, press C__ALL. Clearing of individual DTCs (C__ONE) is not supported by the ECS.
10. The New Generation Star (NGS) Tester or equivalent will retrieve DTCs again after Clearing DTCs, and if any remain they will be displayed. Hard DTCs will be redisplayed after clearing DTCs since they cannot be cleared from the ECS.
