Service or repair of the Parking Assist Distance Sensor happens when the vehicle sits in neutral position on a hoist. The process of removing the rear
Bumper cover is essential only because the outer rear parking aid sensors need direct accessibility while accessing the inner sensors does not require the cover's removal. By pressing the retaining tabs you can detach the parking aid sensor(s) while you disconnect their electrical connectors when the rear bumper cover is taken off. Installation of the new sensor should follow the reverse steps of removal.
