The sensors for parking assistance (objects to close as you reverse) quit working. The switch that turns them on will not turn on. You turn it and the red light stay on indicating nothing changed, they are still off. Why? what do I do ?

Hello,

There could be two things going on, first one of the sensors is unplugged or has gone bad, or the control module has gone bad. also there is a fuse that controls the system I would check that first, here is a wiring diagram so you can look at the system and do some checks.

Please run some tests and get back to us so we can continue helping you.

Best, Ken
