Before Pinpoint Tests

WARNING: This page is about a different car, the 2009 Mercury Milan and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before entering pinpoint tests, check the transaxle, vehicle, Transmission Control Module (TCM) and PCM wiring harnesses for correct connections, bent or broken pins, corrosion, loose wires, correct routing, correct seals and their condition. Check the PCM, sensors and actuators for damage. Refer to the Introduction - Gasoline Engines article.

NOTE: If a concern still exists after electrical diagnosis, refer to Diagnosis By Symptom .

If DTCs appear while carrying out the on-board diagnostics, refer to Diagnostic Trouble Code (DTC) Charts for the appropriate repair procedure. Prior to entering pinpoint tests, refer to any TSBs for transaxle concerns.
