Parking assist sensor problem.
 

This is for my 2004 xc90. My wife backed into a pillar in a garage and hit right on one of the park assist sensors. After that a warning message that says "parking services required" shows up on the dash board. So I took off the rear bumper off today and replaced the sensor that is obviously damaged. But the warning message wouldn't go away. So my question is - do I need to reset the parking assist system to erase the warning message? Or is it possible that more than one of the sensors was damaged?

Could be more than one sensor. All the sensors in the rear are the same part number.


30765108 is the part. Also check the wiring back there. That wire some times breaks right at the sensor plug.
