P0614-ECM/TCM INCOMPATIBLE
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 a DTC will set.
-
When Monitored:
Continuously with the ignition on.
-
Set Condition:
If the TCM detects that the Powertrain Control Module (PCM) software level is incompatible with the TCM software level.
Possible Causes |
|---|
| CONTROLLER(S) NOT PROPERLY 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 FLASHABLE
| 1. | With the scan tool, record the vehicles TCM and PCM part numbers. |
| 2. | Verify the model year and make of both the TCM and PCM part numbers. |
| 3. | Flash and program the controller(s) with the correct software that corresponds with year and make of the vehicle. |
Were you able to update (flash) the controller(s) successfully to the proper software levels?
Yes
- Test Complete.
- Perform the NAG1 TRANSMISSION VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure).
No
- 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 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).
