Rear Differential Pump Pressure Sensor
The rear differential pump pressure sensor is a input signal (PWM) to the brake ECM. The sensor is designed to determine the outlet pressure of the rear differential pump. The pressure sensor is a PWM sensor. The signal is available to other modules through the Catr Data Link.
The rear differential pump pressure sensor is connected to the brake ECM through contact C. The sensor is being supplied with +8V. 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.
