What is the traction control system?

When a vehicle without traction control attempts to accelerate on a slippery surface like ice, snow, or loose gravel, the wheels are liable to slip. The result of wheel slip is that the tires spin quickly on the surface of the road without gaining any actual grip, so the vehicle does not accelerate. read more

Traction control works with the ABS system, but serves a different purpose. While the ABS system kicks in when you’re trying to stop your vehicle, traction control engages when you try to accelerate. read more

A traction control system (TCS), also known as ASR (from German: Antriebsschlupfregelung, lit. 'engine slippage regulation'), is typically (but not necessarily) a secondary function of the electronic stability control (ESC) on production motor vehicles, designed to prevent loss of traction of driven road wheels. read more

When the traction-control system determines that one wheel is spinning more quickly than the others, it automatically "pumps" the brake to that wheel to reduce its speed and lessen wheel slip. In most cases, individual wheel braking is enough to control wheel slip. read more
