Parking Aid System Operation
WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The parking aid system calculates the distance to an object around the rear of the vehicle using 4 ultrasonic sensors. The parking aid sensors detect objects approximately 1, 524 mm (60 in) from the rear of the vehicle, 508 mm (20 in) from the rear side of the vehicle, and 304.8 mm (12 in) above the ground.
The PAM calculates the distance to an object within the 170 degree semicircular (azimuth) area around the rear of the vehicle. A variable-rate warning tone is generated from a speaker attached to the PAM .
The PAM can be diagnosed with a scan tool.
