40/41TE Automatic Transaxle (GPEC)

P0602-CONTROL MODULE PROGRAMMING ERROR/NOT PROGRAMMED

For a complete wiring diagram Consult Diagrams/Electrical.

Theory of Operation

The controller is programmed during manufacturing with generic software to facilitate testing. This software does not have the proper calibrations to control a transmission in a vehicle. The check for generic software is made at power-up. If generic software is detected by the controller the MIL will light immediately and the MIL will stay on even if the fault is cleared, until the proper software is installed. Note: The Transmission will be placed in limp-in mode.

- When Monitored:
Check for generic software is made at power-up.

- Set Condition:
If generic software is detected by the controller a MIL will light immediately. This DTC is designed to inform the technician that the controller still has generic software installed.
