Theory Of Operation

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

The Transmission Control Module (TCM) 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 illuminate immediately and will stay illuminated until the proper software is installed.

This DTC will cause the Transmission to be placed into limp-in mode.
