Anti-Lock Brake System (ABS) Module
WARNING: This page is about a different car, the 2013 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The ABS module is attached directly to the HCU and is the electronic control unit for the parking brake system. The ABS module monitors all switch inputs, sensor inputs and High Speed Controller Area Network (HS-CAN) messages that relate to the parking brake system, then directly controls the parking brake actuator motors. The ABS module also sets Diagnostic Trouble Codes (DTCs) in the event that a system or component failure should occur.
