Before Pinpoint Tests

Before Pinpoint Tests

NOTE: Prior to entering pinpoint tests, check the powertrain control module (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 Computers and Control Systems.

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 Charts for the appropriate repair procedure. Prior to entering pinpoint tests, refer to any TSBs and OASIS messages for transaxle concerns.
