like I said its all in the manual. you have to hold the button for 5 seconds to turn it all off, if you just press it once you can spin it all you want as long as you dont fishtail. Its realy three different systems acting as one. We refer to all of them as one "TC" when in fact its Traction Control, Electronic Stability Control, and Roll Stability Control. Its all detailed out in the manual and a good read I suggest everyone read it.
