Hello, I'd check the fuses and fuse circuit. Also chek the back-up lamp switch, should be on the trans housing. The fuses should be in the underhood fuse block. My info shows the fuse goes hot when you turn the key on.

Check the B/U lamp fuse 25 amp in the underhood fuse box. That circuit should be hot with the key on, even if the fuse is ok, if there is no voltage feed, it won't matter.
