Diagnostic Procedure
WARNING: This page is about a different car, the 2004 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
- Retrieve all DTCs stored in RCM memory by executing RETRIEVE/CLEAR CONTINUOUS DTCs. See RETRIEVING DTCS .
- Run on-demand self-test to determine what DTCs are currently being sensed by RCM. See ON-DEMAND SELF-TEST .
- If stored DTCs are different than current DTCs, always repair current DTCs first.
- If different continuous DTCs are displayed from memory than on-demand self-test, repair on-demand self-test codes first, then repair continuous codes.
- If no DTCs are retrieved and symptoms are observed, refer to diagnostic symptoms table. See DIAGNOSTIC SYMPTOMS table.
