What does it mean when a vehicle displays TCS?

When a vehicle displays TCS, it indicates a malfunction in the Traction Control System. Use a decoder to read the specific fault code and proceed with repairs based on the fault code's instructions. TCS, or Traction Control System, is also known as the Track Control System. Its components include: ECM (Engine Control Module), TCM (Transmission Control Module), TCS computer, ABS computer, and wheel speed sensors. The working principle of TCS is: it relies on electronic sensors to detect when the speed of the driven wheel is lower than that of the driving wheel, and it automatically adjusts ignition timing, reduces throttle opening, decreases throttle input, downshifts, or applies brakes to the wheels to prevent wheel slip.
I once encountered the TCS light popping up on the vehicle dashboard while driving on the highway during heavy rain. TCS stands for Traction Control System, which automatically intervenes when wheel slippage occurs. For example, if a tire spins during rapid acceleration, the system will immediately limit engine power output and may also apply braking to the slipping wheel. Common reasons for the light coming on include: the wheel speed sensor being covered in mud and reporting a false fault, uneven tire tread wear causing inconsistent grip, or moisture affecting the system's electrical connectors. That time, after gradually slowing down and pulling over, I found the right front wheel's inner sensor was clogged with mud. After cleaning it and restarting, everything returned to normal. Remember to rinse the inner wheel arches during regular car washes to prevent this.
