So that’s your ESC light, aka traction control. When your steering wheel is off center a certain amount the it will kick on. If the wheel goes further off center the vehicle will actually start applying brakes in attempt to regain traction. In order to correct that you need recenter your steering wheel via your drag link. You should be able to google how to adjust your drag link but it’s a very simple fix.

 

This is not a problem that I have come across before but it sounds fairly simple. When you put the new adjustable track bar in, it was not the exact same length as the old one. If you have already adjusted the track bar, making 100% sure there is the exact same amount of tire sticking out or under the fenders, you should not UNCENTER the axle to fix the steering wheel. Once your front axle is perfectly centered, you need to center your steering wheel to be perfectly straight when going down the road. You do this by adjusting the drag link between the pitman arm (steering gear box) and the right side steering knuckle. Turning it one way will make the steering wheel get worse, turning it the other way will bring it back to center. The computer can only tolerate the steering wheel being off center about 1-2 degrees before it messes with the brains of the skid control systems. First, make sure the axle is perfectly centered, then center the steering wheel and you should be good to go.

 

Also you probably need to make sure your track bar is set properly. Make sure the axle is centered under the vehicle. You can do that by using a tape measure and making sure that each wheel is the same distance from the frame. If it is not shorten or lengthen the track bar. You can use a ratchet strap attached to the frame and the axle to make adjustments. After the axle is centered and track bar is set you will want to adjust your drag link if the wheel is not centered.

 

2016 Sport 2dr. My traction control light would come on when traveling right hand turn on/off ramps.
My steering wheel was off center, and the camber was messed up from the lift installed by the PO.
Once I fixed the camber (with adjustable control arms), and centered the steering wheel (drag link adjustment), that problem disappeared.
Now it's on to the other problems.
