Auto Dimming High Beams

[jason6695]

I've had my 2019 RAM 1500 Laramie since new, and auto high beams have never worked for me. I did mention it in the dealership a couple times over the years and they said they didn't see any codes for it and it should be fine but its never has worked for me.

My window sticker says I should have it, I see the option on the menu in the radio and its turned on, but I don't see anything about it on the evic when I turn high beams on and they don't dim when vehicles approach. Is there something else I need to do to make it work?

Two steps, one, you turn it on in Uconnect and two, you push the stalk forward to turn them on. Nothing else to do. If it isn't working, something is wrong with the system.

This ^^^^ but remember there is a speed limitation on auto high beams, the vehicle has to be moving at (if I remember correctly) 25 MPH or faster for the system to engage.

Now the question is why are your high beams not turning off when a vehicle is approaching, well, I don't know. On my truck, they dim on false positives like reflections from road signs and low-hanging tree branches.

If I were in your shoes, I would pull the build sheet for your truck and verify it was built with this option. If so, go back to the dealer. On my build sheet, the auto-high beams are listed as "Auto High Beam Headlamp Control".

The headlight switch also has to be set to "Auto."

This is why I never use it and do manually

I rarely use it also. It swithes to Dim way too early and falses off reflective signs way too often.

In my research on this issue I found the "Customer Satisfaction Notification VF2 Auto High Beam Headlamp Control " for the 2020 MY. Given the resolution for this issue was rebuilding the bcm config I thought my issue might have been software related. Since I have Alfaobd I downloaded my configuration and compared it to the bcm settings in the how to post for adding ACC, FCW, Lane Assist, Auto High Beam headlights and rain-sensitive wipers since that is the feature group I had from factory.

My truck had the setting:

Auto High Beam Module Location: CRVMM

When it should have had:

Auto High Beam Module Location: IRCM

Once I made the change I now get the message saying they've been enabled when I'm in auto and move the high beam switch forward. I havn't been out yet to test that it works but now that I'm getting the message is promising.

Do you have ACC, FCW, LKAS, etc?

 

[jason6695]

Do you have ACC, FCW, LKAS, etc?

Yes I do.

 

[vincentw56]

Yes I do.

Oh, then that is why. That other setting is if you have auto high beams, but no ACC, etc. Someone screwed up the setting from the factory I guess, unless you added ACC, etc yourself.

My 2020 was like that, dimming from reflections, but my 24 works flawlessly. I even made a comment on a thread, where someone wanted to add the feature. Every vehicle before this one, even my 21 Durango, reflections from street signs, dimmed them. Now I use them all the time.
