For a complete wiring diagram, refer to the Wiring Information Electrical Diagrams

Theory of Operation

The Transmission Control Module (TCM) performs various internal tests to verify proper controller operation. If the TCM detects an error with the controllers processor, the controller will enter Limp-in mode and illuminate the MIL.

- When Monitored:
Continuously with the ignition on.

- Set Condition:
If the TCM detects an error with the controllers processor.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Testing and Inspection

Repair

- Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace the TCM.
- Perform NAG1 TRANSMISSION VERIFICATION TEST.Transmission Verification Test
