P0817-STARTER DISABLE (P/N) CIRCUIT/OPEN
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.
Possible Causes |
|---|
| CONTROLLER NOT CODED |
| TRANSMISSION CONTROL MODULE (TCM) |
Always perform the NAG1 Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 28 - DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure).
CHECK IF TCM IS CORRECT
| 1. | Flash and reprogram the TCM with the correct software in accordance with the Service Information. |
| 2. | Perform the NAG1 TRANSMISSION VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure). |
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 in accordance with the Service Information.
- Perform the NAG1 TRANSMISSION VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure).
