The Anti-lock Brake System (ABS) control module consists of an integrated control module and a four-channel Hydraulic Control Unit (HCU). The control module uses the HCU to modulate hydraulic pressure to the individual wheel brakes to control the brake functions.
The ABS control module is installed in the front corner of the engine compartment, on the driver side. A multi-pin electrical connector provides the electrical interface between the control module and the vehicle wiring. Hydraulic pipes and hoses connect the HCU to the master cylinder and the brake calipers. The primary and secondary outlets of the master cylinder are connected to the primary and secondary circuits within the HCU. The primary circuit in the HCU has separate outlet ports to the front brakes. The secondary circuit in the HCU has separate outlet ports to the rear brakes.
