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.

Note: If a concern still exists after electrical diagnosis has been done, refer to the Diagnosis by Symptom. AX4S

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 for transaxle concerns.
