I don't know if it's country specific, but I seem to recall someone who disconnected the AFS module to get rid of the error but then also lost DRLs.
This is the thread I'm thinking of, though that was with single beam

@hirurg78 Did you ever find a solution to this? I’m experiencing the exact same thing.
Hi there!
Great job!
let me ask you couple questions.
I also did this conversion, But I cant get the check headlight leveling system message out. I disconnected the original AFS module, but techstream successfully communicating with that unit until light is OFF., however body ECU has an error communication with ECU. Once I turn the light ON, techstream stop see the AFS unit at all). I believe that there are kind of analog of AFS module installed in left headlight ballast. Question is why it stop communicating with techstream once light is ON and why Body ECU dont see it? Andrey, Let me ask you couple questions.
2. All data packages works beside the one when only DRL is ON and one for startup the lights (when low beam is ON and high beam diodes starts simultaneously) do you know how to make it works?

old AFS has to be disconnected.
of note: headlight ballasts have to be brand new, because once you initialize them they’ll trigger error message on another vehicle

do you have 16+ Body MPX as well? You have to have it. 16+ headlights have AFS in the left ballast, and they have to communicate with 16+ body MPX to run DRLs, high beams etc.

Ahhhh wait. That may be the issue is I’m not sure if the ballasts are new, because I have the mpx from a 16+ GSF, and disconnected the old AFS. Specifically I’m getting the code U0142 Lost communication with body control module B. For the initialization, under AFS, I went to ECU information sync, then ran it and it said “this ecu has already been synchronized” then went to the height sensor initialization, set that up based off the fuel amount. Not sure if there is some other initialization I’m missing to do, or if it’s more than likely I need new ballasts?

Thank you greatly. Looks like I’ll be looking to buy those and keep my fingers crossed.

It looks like the "ECU information sync" option in your first screenshot. That's at least what your second code B2451 is for. Although it's weird because I haven't seen that step mentioned by others in other threads. But I don't know if everyone is buying new ECUs?
Try the GSF suggestion first, though.
