2026 F250 trailer brake controller programming

Hi there I’m seeking some advice with using FORScan to program a factory trailer brake controller to my 2026 250 STX. Has anyone trikes this yet?

This is my first time using forscan, I changed the 3 settings in ipc first to no avail. I found settings for the trailer brake controller in abs and pcm as well and switched them on with no success. I have since reverted all settings to factory. Am I missing something or is it possible that I am not able to program this myself on a 2026?

Did you ever get this resolved? I'm trying to do the same install on my 2026 F250 XL.

Its crazy for a 3/4 ton truck not to include it. I didn't even think it was a question I had to ask

It is crazy isn’t it. I missed the fact that it wasn’t in there on my test drive.

I was not able to get it to work with FORScan, I ended up dropping it off at the dealer and having them program it, $50.
