What is Traction control system?

A Traction Control System or TCS. Is the system that helps your wheels from skidding while riding in water or other slippery areas. It also helps your tires from skidding or making the scratching sound when for say, "Taking off fast from a red light". Traction control is an option on many cars today. When engaged, it "senses" when a driving tire has no traction. The system will then compensate for this by slowing the spinning wheel through partial application of the brake, reducing power or both. The system uses wheel speed sensors to monitor the wheel speed. When traction is lost the sensor prompts the brake computer to partially apply the brake to the wheel that is spinning, allowing it to gain traction. Sort of like Antilock brakes in reverse.
