The Parking Aid Module (PAM) supplies a reference voltage and signal return to the parking aid sensors. Each of the parking aid sensors has an individual input signal to the PAM . When an object is present behind the vehicle, the PAM receives an input signal from the sensors and determines the distance of the object to the vehicle. A fault condition occurs when the PAM detects an open in the parking aid sensor circuits or the parking aid sensor input signal is shorted to ground.
