Okay, I'm no engineer, and I haven't had a lot of experience with sway events (thankfully, and knocking on wood), but it still doesn't make sense to me. In order to induce a jack knife situation, the trailer would have to be significantly out of line with the truck? If SC or TC on the truck engages, thereby engaging the brakes, the trailer's brakes will also engage, right? So I'm just having difficulty seeing how this could happen?
Perhaps, maybe if the truck is actuating brakes on individual wheels (like some ABS systems will do) it's not sending braking to the trailer? I wonder what instigates an integrated TBC to send voltage to the trailer brakes? If it's the pedal, that could cause a problem. And what about an aftermarket brake controller? If the SC and TC systems on the truck are not "talking" to the brake controller and sending voltage to the trailer brakes during an event, that could conceivably cause a problem?
But I still don't see how the hitch would interfere with all this?
It would be VERY interesting to me to see the technician's explanation on this.
