Trunk lid lights not working

Hi all,

My trunk lid lights are pretty much not working, except for one license plate bulb (left). I checked the wiring under the trunk trim but I haven't checked the trunk-body grommet tube thing wiring yet (not extensively)

I also got some error codes (pics) that I think are related but searching online doesn't get me any helpful tips.

What do these codes mean? How do I fix the lights?

Reset the short circuits in the frm and it will send power to the lights again.

You probably have shorted wiring in the boot lid harness. Fix that first. Reset the counters. Check fuses. And you should be good (granted bulbs are ok)

Yea I took a peek in the wiring grommet tube between the trunk and body, saw a couple worn/exposed wires

I guess this is a pretty common e90 issue lol
