Commander 4WD V8-4.7L (2008)
NOTE: The park assist sensors (3) and the sensor spacers (2) are each available for separate service replacement. The sensor brackets (1) are
bonded and integral to the back side of the rear bumper fascia (4).
1. Engage the O-ring spacer (2) around the circumference of the sensor (3) membrane protrusion.
NOTE: 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.
2. Align and insert the sensor into the sensor bracket (3) on the back of the rear bumper fascia (4) until the bracket latch features are fully engaged
over the top and bottom tabs of the sensor. Be certain that the sensor membrane is flush with the outer surface of the fascia.
NOTE: 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.
3. From the back of the fascia, reconnect the wire harness connector to the sensor connector receptacle.
4. For the two inboard rear park assist sensors only, reinstall the bumper fascia onto the rear of the vehicle. See: Body and Frame/Bumper/Rear
Bumper/Rear Bumper Cover / Fascia/Service and Repair/Rear Fascia - Installation.
5. Reconnect the battery negative cable.
