Abs Module

The anti-lock brake system (ABS) module controls the brake functions using the hydraulic control unit (HCU) to modulate hydraulic pressure to the individual wheel brakes.

The anti-lock brake system (ABS) module is attached to the hydraulic control unit (HCU), on the driver side inner fender in the engine compartment. A 46 pin connector provides the electrical interface between the anti-lock brake system (ABS) module and the vehicle wiring.
