Theory Of Operation
WARNING: This page is about a different car, the 2013 Jeep Patriot and 2013 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.
The TCM receives the On/Off-road signals from All Wheel Drive control module (AWD) and the Totally Integrated Power Module (TIPM) over the CAN BUS. If the signals from AWD and TIPM do not match, this DTC will set.
