Clear faults, no return, no flashing green light, same behavior. I'm considering three things right now: I was deep inside the headlights to do the projector replacement and removed the circular pcb board which I assume is the alignment guides. It rained recently and they fogged up inside meaning my seal was not complete enough. The modules on the bottom are from the donor headlights and not my originals, which I still have and were known good boards.

They need to come off, that I know. Does anyone have constructive ideas on testing? I'm thinking a baseline plan of attack:
- disconnect new, connect old, see if fault exists on passenger side
- remove bumper, remove new, swap sides, see if fault moves to drivers side
- swap modules, see if fault follows modules
- all else fails, bake at 200F for 7 minutes and serve while warm

and they need leveling with the white hex adjusters, but I gotta get the auto level figured out first. I searched ISTA for some sort of LCM or auto level "current data" operation/thing to run and didn't find any. My INPA is busted for some reason and my laptop is slow as balls. So I ordered a crappy 128GB SSD for this diag laptop. What a situation lol. They're loads better, especially once they're aimed correctly. Clear cutoff and a beautiful blue edge
