The controller is programmed during manufacturing process 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 (ignition on). If generic software is detected, the MIL will illuminate, transmission will be placed in limp-in, and will stay in limp-in even if the fault is cleared or until the proper software is installed.
