Why does my traction control randomly turn on?
What causes the TCS light to turn on? The most common cause is a loss of traction due to slippery road conditions. When this happens, it means your tires do not have an adequate grip of the road, causing them to slip. The system will alert you that it’s on by flashing a TCS light on your dash.
What happens when traction control kicks in?
Traction control uses wheel speed sensors to detect when one driven wheel is spinning faster than the other wheels. In this condition, the ABS activates on the slipping wheel to slow its speed. Once the slipping wheel slows down, it is able to grip the road again and the brake on that corner of the vehicle is released.
When does traction control go off in Toyota?

What do I need to know about traction control?
4LO – One Push (“Traction Control OFF” light on). Puts the truck into the same mode as the 4Hi setting above and allows the tires to spin at speed, clearing mud and snow from the tread. Tire pressures – dropping to about 15 psi of tire pressure in the snow and sand will create a larger footprint for the tire to grab with.
When does ATRAC go on on a Toyota truck?
ATRAC is defaulted to “ON” when the truck is started in any drive mode (2WD, 4HI, 4LO). (as identified by @Clay Grazer, TRAC is the 2wd term and ATRAC is the 4wd term, but they function the same, so the terms are used interchangeably here) Special Note: If you hit the brake pedal while ATRAC is actively working, it shuts off.
