We have a 2020 style Escape Compact C502 with rear and side parking sensors. The whole system appears to have failed, you get no notification when engaging reverse. All reversing lights and cameras work as original. I am assuming somehow the system has been deactivated as, after a recall last year for something unrelated, the alarm system had to be reset as well. But I did not notice the parking sensors had failed at that time. Has anyone any idea how to reset the system please. According to the book the fuse for the sensors also runs the radio and a host of other items all of which are working. The van was registered in 2021 but appears to be the previous years model. Many thanks, new member. We have a dog called Bilbo hence the van is called Bag End.
