Thx a lot for that !! This weekend ill test that out for sure! Actually to answer your first question its both, hatch side with the reverse light (not working)and body side with the LED bar (not working)below the blinker . The entire hatch side is dead!Body side, door side, or both? I'm guessing it's door-side, based on your description?
The BCM provides power directly to the turn signals and reverse lights, so I would use a volt meter to test the harness at the rear combination lamp to see if the BCM and wiring harness are good. If they are, check the connectors for corrosion and good contact.
Pin 2 is power for reverse lamp
Pin 4 is power for turn signal
Pin 5 is ground
