Brake Pressure Sensor

The brake pressure sensor is mounted on the DSC hydraulic unit in the front axle circuit. The sensor is provided with a 5V reference voltage by the DSC control unit.

The sensor provides the control unit with an analog signal proportional to brake pressure.

Voltage increases with increasing brake pressure.
