Main use

The control module continually calculates wheel speed for all four wheels and regulates with braking or an engine torque limitation request if there is a difference between wheel speeds and a limit value is exceeded.

The hydraulic unit provides brake pressure to the wheel brakes and holds or evacuates brake fluid as necessary using internal unit valves.
