Park Assist Sensor: Operation
WARNING: This page is about a different car, the 2006 Dodge Magnum, 2006 Dodge Charger, and 2006 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
The Park Assist Sensors:
- Generate ultrasonic pulses when triggered by the Park Assist Module.
- Reception/filtering of ultrasonic energy received.
- Signalling the module of received ultrasonic pulses that meet threshold criteria.
The sensors are supplied power by the module. The sensor supply is enabled when the sensor function is necessary.
The sensors detection length from the rear of the vehicle is 0.3 meters to 1.5 meters. This area extends around the rear side of the vehicle. The sensor detection height from the ground is 0.2 meters to about 1.5 meters.
- Ensure that the rear bumper (sensors) is free of dirt and debris to keep the system operating properly.
- Jackhammers, large trucks, and other vibrations could affect the performance of the system.
- Ensure that the parking brake is not applied.
If "Service Park Assist System" appears in the EVIC after making sure the rear bumper is clean, proceed to diagnose the system using a scan tool and the appropriate diagnostic information.
