WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
The Trailer Module (TRM) receives inputs from the BCM over the MS-CAN to control voltage to the trailer tow connector for the LH stop/turn indicator, RH stop/turn indicator and trailer battery charging.
