Component Description

Parking Aid Sensors 

The parking aid sensors are wide beam ultrasonic sensors. The sensors continuously send out ultrasonic signals to detect objects and communicate the information back to the PAM.

Only objects which reflect enough sound waves are detected by the sensors. This varies due to the shape, surface properties and size of objects being detected. Incorrect sensor alignment, dirt covered sensors, heavy rain or snow can cause objects not to be recognized.

PAM 

The PAM calculates and reports (via audio system tones) the distance between the front or rear bumper of the vehicle and an object. The PAM is integral to the BCM and requires PMI when replaced.
