What does TC mean when displayed on the car dashboard?

When the vehicle displays TCS, it indicates a malfunction in the Traction Control System. Below are the relevant details: 1. When the Traction Control System malfunctions, a decoder should be used to read the specific fault code, and repairs should be carried out based on the fault code's instructions. 2. TCS stands for Traction Control System, 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. 3. 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. It then automatically adjusts ignition timing, reduces throttle opening, decreases throttle input, downshifts, or applies braking to the wheels to prevent wheel slip.
That day I was driving my friend's new car on the highway when suddenly a yellow TC light popped up on the dashboard, scaring me into pulling over to check the manual. Turns out TC stands for Traction Control System, like an invisible traffic cop managing all four wheels. When tires slip, it automatically applies brake pulses or reduces throttle to prevent skidding. There are three common reasons for the light to come on: either the system is actively intervening during slippery conditions like snow driving; or you accidentally pressed the button with the skidding car icon and turned it off; the most troublesome scenario is an actual system malfunction, like a wheel speed sensor caked with mud or a faulty ABS pump. Testing is simple: park and restart the vehicle - if the TC light stays on, it's likely a real issue requiring a dealership scan tool to read the trouble codes.
