If DTCs appear while performing the On-Board Diagnostics, refer to the EEC-IV On-Board Diagnostic Trouble Code Description Chart for the appropriate service procedure. Prior to entering Pinpoint Tests, refer to any TSBs and OASIS messages for A4LD transmission concerns.

NOTE: Prior to performing Pinpoint Tests, check the powertrain control module wiring harness for proper connections, bent or broken pins, corrosion, loose wires, proper routing, proper seals and their condition. Check the powertrain control module (PCM) (12A650), sensors and actuators for damage. Refer to the Powertrain Control/Emissions Diagnosis Manual.

NOTE: After electrical diagnosis has been performed and a concern still exists, refer to the Hydraulic/Mechanical Diagnostic Routines under Diagnosis By Symptom. A4LD
