Electronic Brake Control Module


This computer-based unit interprets inputs from the speed sensors, the brake lights and the brake warning lamp circuit. After processing the inputs, the unit controls output electrical signals to the hydraulic control solenoids, causing them to increase, decrease or hold brake line pressures. Additionally, the controller oversees operation of the pump motor and the ABS warning lamp.

Additionally, the controller constantly monitors system signals, performs a system actuation test immediately after engine start-up and can assign and store diagnostic fault codes if any errors are noted.
