When I puchased my 2016 truck I would get a warning when someone was approaching the rear side of the truck. Now it doesn't. If I backing up the rear warning works if I'm approaching something strait on but not on the corners. I used a toner to check the rear sensors. The inner 2 make a noise but not the rear corner 2. Checked a new truck on the sales lot and got the same results. Why don't the rear corner sensors make a noise? Dealer found no codes on the pam module.
