Before Pinpoint Tests

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

NOTE: Prior to entering pinpoint tests, check the PCM wiring harness 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 has been carried out, refer to Diagnosis By Symptom .

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