2021 F-150 Brake Controller problems

Guessing that these fairly new 'highly integrated' OEM brake controllers are running in 'open loop' and the master/slave & it's lookup tables are a mess...not all the time, but occasionally gets into a state that the +100 computers get confused...ABS, traction control, sway control, engine/tranny computers, etc

Suggest to you all on that forum to consider a trial where one would install a P2, but leave all the OEM TBS wiring alone.

A dedicated trailer brake controller only deals with ONE external thing...the trailer brakes. Yes, it has inertia sensors, etc, but it is a standalone system NOT tied into the complex TV's systems.

Betcha the problem goes away

So ditch the fact that it has built in braking system? ****, that's one of the nicer features on my last several trucks that was not available just 10 years ago or so. I was really getting sick of putting a new brake controller in every truck! Bet I've installed/moved 10 controllers between personal rigs and installed close to 20 in my assigned company trucks. And who knows how many more in other work trucks.
Hell, I thought I died and went to heaven when they finally started pre-wiring them for brake controllers.

What you suggested is akin to "my power windows don't work right."
"Well that there new fangled stuff just aint worth a hill of beans. You should replace them with manual crank windows!"
