Anti-Lock Brake System (ABS) Module

The ABS module is attached directly to the HCU and is the ECU for the ABS. The ABS module monitors all sensor inputs and all HS-CAN messages relating to anti-lock brake control, then directly controls the solenoid valves and the hydraulic pump motor in the HCU.

The ABS module and HCU are connected together but are serviced separately. When a new ABS is installed, the module must be programmed with the vehicle information. Refer to: Communications Network - System Operation and Component Description .
