P0817-STARTER DISABLE (P/N) CIRCUIT/OPEN

For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

The Transmission Control Module (TCM) performs various internal tests to verify proper controller operation. If the TCM detects that the variables that dictate the vehicle application are not present the DTC will set.

- When Monitored:
Continuously with the ignition on.

- Set Condition:
If the TCM detects that the variables that dictate the vehicle application are not present.





Always perform the NAG1 Pre-Diagnostic Troubleshooting procedure before proceeding. NAG1 Pre-Diagnostic Troubleshooting Procedure
CHECK IF TCM IS CORRECT
1. Flash and reprogram the TCM with the correct software.
2. Perform NAG1 TRANSMISSION VERIFICATION TEST. NAG1 Transmission Verification Test

Did the DTC reset after the Verification Test?

Yes

- Using the schematics as a guide, check the Transmission Control Module (TCM) pins, terminals, and connectors for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace and program the TCM.
