Low beam headlight error, circuit 56??
Hey everyone,
So after that huge storm in So cal a few days ago, my car gave me an error for my right side low beam. Upon physically checking, the right bulb isn't working. I thought the bulb has burnt out, so I took it to an indy and they tried switching to a new bulb which didn't work either. They eventually pulled the codes and it gave a Circuit 56 and LIN bus error.
I believe circuit 56 is the fuse terminal for the headlights? Does anybody know if this is as simple as a burnt fuse or is it a much more complicated issue?
I have Bi-Xenons and because of the problem, I also get an error on my dashboard saying the adaptive headlights are not working. My high beams also does not work on my left light now.
Any advice/feedback will be greatly appreciated..
