Park Assist Sensor - Description

DESCRIPTION





Vehicles equipped with the park assist system have four park assist sensors (1) installed on the rear bumper. Only the membrane (3) of each sensor is visible through a hole in the outer vertical surface of the bumper. The remainder of each sensor including the sensor mounting bracket, the sensor spacer and the sensor wiring connection is concealed behind the bumper. A sensor wire harness behind the bumper connects the sensors to the vehicle electrical system.

Each of the four sensors is identical in construction and is interchangeable. The electronic circuitry and a communication chip for each sensor is enclosed and protected within the molded black plastic sensor housing. The housing includes an integral connector receptacle (4) and two integral latch tabs (2). The sensor membrane extends from the surface of the sensor housing, and is finished to match or contrast with the outer surface of the bumper.





The numbering system for the park assist sensors allows for up to twelve sensors on the vehicle, six front and six rear. The sensors are numbered in a clockwise manner starting at the left front bumper. The left front sensor (if equipped with front park assist) is the number 1 sensor. The numbering continues in a clockwise direction around the vehicle. Since this vehicle uses only four rear sensors, sensor numbers 7 and 12 are omitted, so the left rear sensor is the number 11 sensor.





A resilient O-ring spacer around the circumference of each of the four sensor membranes (2) isolates the membrane from the openings in the fascia (1). Each sensor is snapped into its own dedicated molded plastic mounting bracket.

The park assist sensors cannot be adjusted or repaired. If inoperative or damaged they must be replaced. The sensors and the spacers are each available for individual service replacement.
