As the name suggests, the traction control system (or commonly referred to as TC, TRC, or TCS) is a safety feature designed to prevent your car from losing traction.

Firstly, the system will apply brakes on the individual wheel that is losing grip. The electronic control unit (ECU, the brain of the car) sends a signal to the hydraulic modulator to rapidly pump the brakes, which involves applying and releasing the brake in milliseconds to the affected wheel. Another way traction control works are by applying engine braking to reduce power to the wheels, or a combination of both power cut and braking at the same time to stabilize the car.

Lastly, please note that having a traction control system in your car is basically useless if you have a poor habit of tire maintenance or lacking in driving ethics because no traction control in the world can save you from stupidity. Please, always practice safe driving habits. Avoid driving aggressively, speeding unnecessarily through a corner, and tailgating way too close to another car. Be safe, everyone.
