Auto high beams not working after Alfa OBD flash

[Jck1994]

As the title says I’m attempting to activate the auto high beams in my 21 1500 big horn, I went through the steps listed on the Alfa OBD threads and can’t seam to get them to work, all setting are correct and I have it in the unconnect screen, but I don’t get the message in the cluster or auto high beams.

This isn’t my first Alfa obd mod as I successfully added the and flashed the trailer brake in. Any ideas on how to get it working would be appreciated, thanks

Do you even have the hardware? You didn't mention that.

Push the turn signal lever to the high beam and leave it. See if it works then.

from what I read the only hardware required was the self dimming mirror ( or westerner the fancy term is ) with the light sensor on it, I have that.

When I flashed it in Alfa obd I set it to use the mirror sensor flipped it forward during the day and they didn’t come on thought all was good, then at night the come on but don’t **** off for light, I’m also not getting the auto high beams on message

No, that is not correct. You do not have the correct hardware. You either need the rearview mirror with the camera on it, or you need to have the DASM (which is for FCW/ACC/LKAS and as a camera on it also). The light sensor is only for dimming the mirrors and that is it.
