I am sorry to hear that the money you spent did not fix the problem. Ours stopped working years ago. Although I miss it I haven't invested in it. I don't know if a diagnostic scan tool could find that or not. These cars are getting old to dump much money into.

 

mine dont look old

 

To anyone have an issues with parking assist it is not the sensors I repeat it is not the sensors it is the control module located in the back door on the left corner it sometimes faults from the trunk being slammed change that and I promise your park assist will work again
