Theory Of Operation

During manufacturing, the controller is programmed with generic software to facilitate testing. However, generic software does not have the proper calibrations to control the transmission in the 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: The transmission will be placed in limp-in mode.
