The thing is, I have a new SAS, but I believe that it's pretty hard to replace it, half of the car has to come out if I'm not wrong, so I'm delaying that as much as possible.

Now concerning AHL, I do have AHL from the factory... If I didn't, I probably wouldn't ever retrofit that haha...

Anyhow, as far as I know, the AHL module is fine. Even physically... I was working on something with GMIII, so everything seems normal down there.

The errors I was getting were pointing out to the Left SMC module (and a to SAS also). I replaced SMCs in both headlights (got them for the price of one) and finally, a few days, ago I managed to code them in with NCSExpert.
But since headlights are still pointing "to the sky" I assume I need to calibrate, re-calibrate or initialize something, but I don't know how.
I was playing with INPA for an hour and didn't manage to find anything. Also in ISTA or P.A. Soft I couldn't find a thing that would do that. Maybe NCSExpert?

Or as I mentioned above, maybe I need to physically adjust the headlights with the two screws on them first?
