P0602 Cotrol Module Programming Error/Not Programed
P0602 code - 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 controller will enter Lim-in mode and illuminate the MIL. Set condition this DTC if the TCM detects that the variables that dictate the vehicle application are not present.
Possible causes P0602 code:
- Control Not Coded
- Transmission Control Module (TCM)
Diagnostic test P0602 code
Check If TCM Flashable
Controller is programmed with genetic software and will not allow the correct vehicle Powertrain management.
1. With the scan tool, record the vehicles controller part number.
2. Select Use Controller Part Number under the Flash Tab.
3. Flash the controller with the correct software.
Were you to update (flash) the controller successfully?
Yes, test complete. Perform the NAG1 Transmission Verification Test.
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 Transmission Control Module (TCM). Perform the NAG1 Transmission Verification Test.
