Component Description: PAM
The PAM supplies voltage and ground to the rear ultrasonic sensors while monitoring a signal return circuit from each sensor. When an object is detected by the sensors and the rear parking aid system is active, the PAM calculates and reports, via audio system tones, the distance between the rear bumper of the vehicle and an object.
The PAM is integral to the BCM but communicates as a separate node on the HS-CAN1.
The BCM requires PMI when replaced.
