Before Pinpoint Tests

If DTCs appear while performing the self-test, refer to the On-Board Diagnostic Trouble Code Description Chart for the appropriate service procedure.

NOTE: Prior to entering pinpoint tests, refer to the TSBs for AX4S concerns.

NOTE: Prior to entering pinpoint tests, the vehicle harness must be checked for continuity and shorts, and the PCM must be checked for any concerns.

NOTE: If any non-transaxle DTCs appear, service those DTCs first. They could affect the electrical operation of the transaxle. Record and erase codes from continuous memory after repairs have been performed. After servicing any DTCs in the Quick Test, the Quick Test should be repeated.

NOTE: Check the PCM system wiring harness for proper connection, bent or broken pins, corrosion, loose wires, proper routing, proper seals and their condition. Check the PCM sensors and actuators for physical damage.
