Component Description

WARNING: This page is about a different car, the 2016 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

Anti-Lock Brake System (ABS) Module

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. Refer to: Anti-Lock Brake System (ABS) and Stability Control .

Parking Brake Actuator Motor

The parking brake actuator motors are single speed reversible electric motors mounted on the rear brake calipers. The motors can be serviced separately from the calipers.

Parking Brake Switch

The parking brake switch is a 3 position switch with 2 sets of 3 internal micro switches, one set is for APPLY and one set is for RELEASE. The 3 switch positions are APPLY (pulled up), NEUTRAL (at rest or static) and RELEASE (pushed down).

Whenever the parking brake switch is disconnected and then reconnected, a DTC sets in the ABS module and the ABS module disables the parking brake system. To restore parking brake system functionality and to clear the DTC, the parking brake switch must be moved through all 3 positions twice within 5 seconds pausing for approximately one-half second when the switch is in the NEUTRAL position between each apply and release.
