@J17GT this issue is happening on your 2023 truck? I updated my headlight control module (2021 Raptor) with the 2023 HCM firmware/software and that has fixed my leveling issue on my 2021…interesting if it’s happening on your 2023 truck. Curious to hear what they say at service. One thing I have to ask though, your headlights are in AUTO and not ON correct? Your dynamic steer is working properly just not the leveling? Have you tested with a jack under the hitch to confirm they are adjusting (but the wrong direction which is what mine were doing) or aren’t adjusting at all? I went to pretty great lengths to collect data to prove to the service center mine was responding inverse to what they should be but then never took it in as I ended up getting into it myself with the help of @antho and after loading the 2023 firmware/software load mine function as they should.
Yes, happening on my 11/22 built 2023 truck with the headlights in AUTO mode. Correct the dynamic steer works as is should.
Ah ok that’s right I remember you saying that now earlier. One thing I did to prove they were adjusting but in the wrong direction was tested (using a jack but you could use a trailer just the same) measure the fender lip to the ground, and I used 1” increments for testing, then had the truck positioned 50’ from a wall and took measurements every 1” of change from the fender lip to the ground. I must’ve posted that data on a different thread maybe I’d have to go back and look. I’ll post again here to save looking around for now though. One was done with the lights in AUTO and engine running while the other was with the engine off ignition off but lights ON so no leveling. My results were pretty clear. I used 300 lbs of sand bags on the tailgate for a light simulated load, then jacked up from there to compile my data.
Talking with @antho he indicated that some 22 trucks have received an update and sounds like most 21’s got left behind without the update while the 23 trucks have the firmware load (ML34-14D067-BE) which seems to have corrected the leveling issue (at least for my truck and anthos truck which are both 21 raptor 801A trucks which had firmware version ML34-14D067-BB). I can’t speak for any non raptor trucks though and the raptors do have a different suspension height sensor setup etc, so they could be in fact be a different firmware than non raptor trucks too I’m not too savvy with all that stuff.
I think I can see those numbers in Forscan to satisfy my curiosity. I could have sworn I did an HCM update but I can't find it on my notes now.
1. Could you elaborate on the update process. Is it as laid out in this thread?:
