Hi.
I have an 02 GC Overland with the genuine Jeep reverse sensor system. Its never worked while ive had it and always been totally dead. I have the installation manual and according to that there should be two 12v feeds to the control unit when its in reverse with the ign on. the feeds are both there and correct. all earths seem to be ok, reversing lights are working. theres a strange bosch thing that looks liek a fuse but in fact is a 240 ohm resistanc. this also checks out ok and has feedon both sides of it. Anyone had anything similar? any ideas? theres no led's, no beeps, nothing.
