Do you really have trailer sway? Sway gets worse with each oscillation, and requires application of trailer brakes to correct. You should NOT be tolerating this kind of sway, as sooner or later the trailer will drag or shove you into the ditch, or worse, into oncoming traffic.
Most likely, the issue is that you have an iffy connection of broken wire in one of your ABS sensors, and the weight of the trailer compressing the suspension is causing the connection to fail intermittently.
sway is probably the wrong word, more like "wiggle" with some heavy winds. I'm wondering if ESC is trying to correct for this, and maybe throwing off a sensor. My other thought was, as you said, the weight of the trailer messing with a sensor connection. but the weird thing is, the errors are staying on when not towing. after a couple days, all clear, no errors or anything. ill be taking a much closer look this weekend when i have some time.
