Well I read some more on the Rear Sensors in the manuals and there is a switch that turns it off and on and if turned off it stays off through key cycles. Unlike the Ford where you could disable it and then the next time you turned the truck on again you had to disable it again. All it tells you in the dash is that the Rear Sensor is disabled when you put it into reverse. I'm still working through the manuals as there are 4 different manuals for the truck. Between all 4 there are over 1400 pages of info. :h Then try to remember all of it that you have read. That is hard for an older guy like me.
