+1, that has to be a software function. The combination switch is a matrix type. If the BCM gets the high beam signal with the Auto off then it's also getting it with the Auto on, it's just overruling your command.D-Rock wrote: ↑Wed Sep 15, 2021 2:48 pmI would say it likely has more to do with the Auto setting. I find that if I use the Auto setting the headlights are very sensitive to ambient light or road signs thinking that they're looking at oncoming cars so it switches them to low beams. They tend to spend much more time on low beams and hardly any time on high beams in the Auto setting.
