Theory Of Operation

WARNING: This page is about a different variant/trim than selected.

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.
