Theory Of Operation

WARNING: This page is about a different car, the 2013 RAM 1500. However, it is still accessible from the selected car via links, so may be relevant.

The controller is programmed with generic software, during manufacturing, to facilitate testing. However, generic 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.
