If you both believe that traction control is "defeated" with the push of a button you're either retarded, or clueless. It's effect is lessened with the push of a button, but it doesn't go away.
It is defeat able, at least on my truck, but in 4WD only. Have to hold the button down for 5 seconds and then it will show "ESC Disabled" on the dash. We were climbing up steep snow covered washes yesterday and it works as advertised. 4WD HIGH with ESC disabled allowed sufficient speed to get through the snow drifts.
