P0602-CONTROL MODULE PROGRAMMING ERROR/NOT PROGRAMMED



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 found, the MIL will light immediately and the MIL will stay on even if the fault is cleared, until the proper software is installed. Note: 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 found, the MIL will light immediately. This DTC is designed to signal the technician that the controller still has generic software installed.
