Parking Assist Distance Sensor: Description and Operation
Description
DESCRIPTION
Figure 1 PARK ASSIST SENSOR
The Park Assist Sensors (Figure 1) are located in the rear bumper fascia mounted equally apart (Figure 2). The sensors generate ultrasonic pulses when
triggered by the park assist module when an obstacle is detected. The sensors then signal the module when reflected ultrasonic pulses are received.
Figure 2 PARK ASSIST SENSOR LOCATION
The sensors detect objects with an ultrasonic pulse that reflects off the object and then is sent to the module to determine the distance of the object.
The numbering system for the park assist sensors allows for up to ten sensors on the vehicle six front and four rear. The sensors are numbered in a
clockwise manner starting at the left front bumper. The lefi front sensor (if equipped with front park assist) is the number 1 sensor. The numbering
continues in a clockwise direction around the vehicle so the lefi rear sensor is the number 10 sensor.
