We had a good amount of freezing rain come through 2 days ago. Ice accumulated on the rear bumper and caused PDC to think I'm backing into something whenever I shift into reverse (constant beep).

Today, even though there is no more ice on the bumper and the car is fairly clean it is still doing the same thing. The middle-left sensor tells me in backing into something when no objects are there. Also, the proximity of the rest of the sensors is now affected in that the others tell me I'm going to hit the car behind me when I'm 2-3 feet away.

Is this one of those things that can fix itself? Is there any reset for the PDC system? FYI, my car has rear only so I do not have the button to disable it.
