Automatic highbeams

[jbirdzee]

I have a 2021 Job 2 Premium E4X. Can the automatic highbeam thresholds somehow be recalibrated with FDRS or Forscan? It seems that the decisions the car makes to turn them on/off assessing oncoming traffic works fine, but taillight detection in my lane seems absolutely terrible.

Recently I did the forscan change to enable fading on/off hoping it could help, but my highbeams will decide to fade on and stay on when im just 5 or 6 car lengths behind the person in front of me. When they use their brakes my highbeams turn off.

The taillight sensing just doesnt seem right….. wife had a ‘16 explorer where the auto highbeams worked fine. I had a ‘14 MKZ that worked fine as well. I figured the tech in this car would have built upon or leveraged how they did that before, but my MME just seems to get it wrong a lot. I’ve had them disabled until my recent try at the forscan config change, and will be returning them to disabled but thought I’d ask on the forum.

i think it makes sense that forscan wasn’t going to help - other than making it slightly less apparent to other drivers my car made a bad decision to blast the highbeams….

If im behind an older car with incandescent taillights…. Forget it - my auto highbeams are on until im nearly tailgating them.

Is it just the way it is, or maybe it can be improved with a diagnostic learning procedure? TIA

Yeah I notice it sometimes has trouble if the taillights are dim or unusually shaped.

Ford, test with a late-model F-150 Platinum, the taillights are shaped like [ ] brackets and it has trouble with those.

But to answer the question, I have not seen anything in Forscan to change the thresholds.
