Traction Control Not Working Properly

I installed a full OME lift on a 2009 TRD OR a couple months back with the carrier bearing drop and everything seemed to go just fine. A couple days after I was driving and hit a small bump while turning left and the traction control engaged - I say traction control because I think it made the beeping sound when it engaged but I guess it could be the ABS - not sure.
This now happens whenever I go around a sharp turn at speed. So, basically I'm going around the turn, hit the apex, and the traction control engages and applies the brakes. Very annoying.

Also, I haven't installed extended brake lines yet (they're ordered) but it doesn't seem like that would be the issue.

Does anyone have any advice on what this may be/what I may have done when I put the lift on?
