Theory Of Operation

WARNING: This page is about a different car, the 2023 Jeep Grand Wagoneer. However, it is still accessible from the selected car via links, so may be relevant.

The Transmission control Module (TCM) monitors the Overdrive/Tow switch circuit for faults. If the TCM detects a fault, a DTC is set.
