Some Ford integrated trailer brake controllers (TBC) get flaky. Don't know if the F150s are similar to my F350, but mine started sending TBC error messages and "trailer disconnected" messages. Also, it may have activated the trailer brakes without me pushing the brake pedal, but the jury's out on that until FR confirms it was not the trailer.
I had a new Ford TBC installed, among with the 7-pin connector and pigtail just to make sure the truck end is okay. $799 hurts but it was better than $800 LOL.
I had the same identical situation happen on my VW Touareg Sport TDI. Turns out it was the Tekonsha Prodigy Rf remote that was shorting out inside, something was a loose connection, one of the manual braking rheostats. Just by moving/rotating the position of the Prodigy RF in my hand caused it to apply the brakes on my Travel Trailer, without touching the switch or the brake pedal. Defective.
Tekonsha replaced the RF controller in the car under warranty, not many questions asked... I think they know it's an issue.
The other thing this Prodigy internal elecrical shorting out did was fry my Trailer brake controller device in my Touareg, a $409 replacement part. Pretty pizzed off about that, it roasted the unit, I had no power to the travel trailer from the tow vehicle to recharge the battery, and no connection at all, no brakes, the whole trip home. Talk about dangerous.
Tekonsha design doesn't play nice with German engineered SUV cars in the Prodigy RF lineup.
