It's late, and maybe I'm not following... did you replace faulty AHL modules (water damage... ask me how I know) or are you retrofitting AHL headlights?

If the former, AHL modules do not need coding. But they do need initialization in INPA.

If the latter, your ZCS will need to be changed to reflect the addition of AHL.

I'm unsure if a non-functional SAS will affect AHL workings. Though... it's a cheap repair (rebuild kit <$100 I believe... been awhile since I repaired mine), so I'd do that and then continue with headlights.
