@Jesse-Infotainment thanks for the input, I reached out to Ryan and showed him the connectors, he said the wire in pin 6 needs to move to pin 5 on both of them.
Thanks Jesse, you nailed it again. I’m gonna repin it and try again

The scary part is @Jesse-Infotainment thought it looked off just by memory. Lol

Ok, so I swapped the pins in the connectors and now the high beams work on the left side has no DTC’s but the right side DTC’s are still coming up and so is the Lin Bus B DTC. Any more thoughts? The headlight work and are now road capable, but it still isn’t turning like it is supposed to. I haven’t even attempted the glare free lighting yet
EDIT: I spoke too soon, the left headlamp is working fine now, has high beams and swivel, right headlamp is still not working correctly, still no high beams

Hi buddy, I got nothing to do but research... Did you get his resolved? If so, what was the issue?

Not yet, a buddy and I ran through the entire wiring harness and all of the wires were good (no broken contacts) so that means either the wiring harness isn't wired up correctly, I have a bad headlamp, or the HCM isn't correctly programmed. I happen to have an extra headlamp on the RHS that I need to plug in and test. I plan to get to that hopefully by tomorrow
Oh man I never saw this.. I wish I would have.
I would check conductivity from pin 5 at the headlamp to the HCM. There may be another issue or bad connection on the lin bus.
i would say programming but it would affect both not one.
You are missing the lin bus at the HCM. Or possibly the HCM harness is pinned wrong also.
The passenger side is pin 6 at the HCM and driver is pin 1 the outer two pins on top row.

You've got enough on your plate. I wasn't going to bother you... yet haha.
IDK why, but the HCM connector diagram is the second connector diagram that I have pulled from PTS that doesn't match what you have. Is there a better place to get the drawings and diagrams? The diagram I have shows PIN 7 and 16 as "unused" and the terminology of the circuit function is slightly different.
I pull mine from oasis.. Mine I know are correct.

7 and 16 are the shield.. I dont think they are important they arent like canbus where high and low. Linbus, is single wire. I believe the Linbus isnt making it the the HCM

Yesterday I checked continuity on pin number 5 from the Passenger side harness to pin 6 AND pin 1 (just for the sake of being thorough) on the HCM, neither of which gave audible feedback on my multi meter.
I also check the driver side harness and got continuity from pin 5 to pin 1 on the HCM.
It seems like the HCM to BCM harness is the culprit, because I got continuity on all the wires feeding from the headlamps into the cab. That or I supposed one of the harnesses is pinned incorrectly, because I do not recall having any dead wires on any of the harnesses when I had them all checked on Saturday. BUT we checked all of the harnesses individually, we did not check them end to end.
At this point I would manually run a wire manually from pin 5 at the passenger side to the HCM pin 6. THat is the cause of the linbus error. All linbus is handled at the HCM on these headlights.
That or chase the wire that is at pin 5 all the way into the car and verify it has continuity until that point. If you have a power probe its way easier.
Once you get Pin 5 of the PS Headlamp to the HCM youll be done. That is all that is missing
