Parking Assist Distance Sensor: Service and Repair

Park Assist Sensor

Removing






• The park assist sensors and the sensor spacers (O-rings) are each available for separate service replacement. The sensor brackets are bonded to and integral to the back side of the rear bumper fascia.

- Disconnect and isolate the battery negative cable. Refer to => [ Battery, Disconnecting and Connecting ] Tools and Equipment.

- Remove the bumper fascia (2) from the rear of the vehicle.

- From the back of the fascia, disconnect the wire harness connector (1) from the park assist sensor (4) connector receptacle.

- Carefully pry the sensor bracket (3) latch features away from the top and bottom latch tabs of the sensor far enough to disengage the sensor from the bracket.

- Disengage the resilient O-ring spacer from around the circumference of the sensor membrane protrusion.

Installing






• The park assist sensors and the sensor spacers (O-rings) are each available for separate service replacement. The sensor brackets are bonded to and integral to the back side of the rear bumper fascia.

- Engage the resilient O-ring spacer around the circumference of the sensor membrane protrusion.

• Production and all service replacement O-ring spacers are tapered. The wide side (base) of the O-ring should be seated against the sensor housing and the narrow side should be oriented toward the outer surface of the sensor membrane and the rear fascia.

- Align and insert the sensor (4) into the sensor bracket (3) on the back of the rear bumper fascia (2) until the bracket latch features are fully engaged over the top and bottom latch tabs of the sensor. Be certain that the sensor membrane is flush with the outer surface of the fascia.

• Be certain that each sensor membrane is properly centered in the openings of the rear fascia and that the O-ring spacers are not pinched. Improper centering or pinched O-rings can be detrimental to proper park assist sensor operation.

- From the back of the fascia, reconnect the wire harness connector (1) to the sensor connector receptacle.

- Reinstall the bumper fascia onto the rear of the vehicle.

- Reconnect the battery negative cable. Refer to => [ Battery, Disconnecting and Connecting ] Tools and Equipment.
