The O.P. asked if the trailer brake controller can activate truck brakes. The correct answer is "no".
And it's a stretch to call truck stability control "trailer sway control". It will do nothing to counteract trailer sway, only attempt to solve whatever difficulty the truck is experiencing as a result of it.
Absent mechanical sway bars etc., the trailer itself will continue to sway unless its own brakes are activated to stop it, which the truck's stability system can't do.
Those are all incorrect answers when talking about Ford trailer brake control.
Our F350 Super Duty has TBC ( part of tow command package that year ) and it all integrates thru the braking system, powertrain control module, etc.
So to the OP, yes it could have happened the TBC was doing that, but you are correct to have it all checked out at your dealer. I would let the dealer do it, and not an independent shop unless you are certain the independent shop fully understands the ford system.
