My 2013 Ford Fusion Titanium shows a message on the left screen saying “check rear park aid” the car is a salvage title with rear damage. The car was fix when I bought it but the message still there, the rear sensors works because when I go into reverse it detects a car passing by, by a a message on the left screen saying “vehicle coming from left” or “right”. And in settings it won’t let me choose the option “rear park aid” Maybe a park sensor out of the 4 doesn’t work or how can I check if any of the 4 sensors works?
I upload images for information
