The Transmission Control Module (TCM) performs basic system checks to ensure proper controller operation. This Diagnostic Trouble Code (DTC) sets if the neutral position has not been learned.

- When Monitored:
Ignition on, with no battery/system voltage DTCs present and not during engine crank.

- Set Condition:
Neutral position has not been learned.





Always perform the AW60T Pre-Diagnostic Troubleshooting procedure before proceeding. Initial Inspection and Diagnostic Overview.
