TBC Module

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 TBC module is the ECU for the trailer brake system. The TBC module monitors all sensor inputs and all HS-CAN messages related to trailer braking and directly controls the trailer brakes using a PWM signal.

When a new IPC is installed on a vehicle equipped with trailer brakes, the IPC must be programmed correctly. For additional information on module programming, refer to Module Configuration .
