Left Rear Parking Brake Pressure Sensor And Right Rear Parking Brake Pressure Sensor
The rear parking brake pressure sensors are inputs to the brake ECM. The sensors are designed to determine the left brake pressure and the right brake pressure. The pressure sensor produces a PWM signal. The brake pressure is available to other modules through the Cat Data Link.
The brake air pressure sensor is connected to the brake ECM through contact C. The sensor is being supplied with +24V. The sensor receives power from the brake ECM through contact A. The sensor contact B is connected to ground.
The ECM monitors the circuit for a short to ground or a short to battery voltage. A diagnostic code will be set.
