What does TC mean when it appears in the car?

When the "TC" indicator light on the car dashboard flashes, it indicates that the "Traction Control System" is active. "TC" is the abbreviation for Traction Control System, which means the anti-skid control system, also known as the traction control system. When braking or accelerating sharply on slippery roads, the wheels are prone to slipping or even losing control, posing a danger. To address such safety issues, the traction control system was developed. Here are additional details: 1. Principle of the traction control system: The traction control system relies on the electronic sensors of the ABS anti-lock braking system. When it detects that the speed of the driven wheel is lower than that of the driving wheel, indicating wheel slip, it sends a feedback signal to the car's system. The car system then adjusts the ignition timing, reduces the throttle opening, decreases the accelerator, downshifts, or brakes the wheels to prevent slipping. 2. Function of the traction control system: The traction control system effectively transfers power to the road surface to avoid slipping while allowing the car to follow the driver's intentions, thereby improving driving safety. However, the traction control system does not guarantee absolute safety; it only reduces the probability and severity of accidents. True safety lies in the hands of the driver and is closely related to the car's condition and maintenance.
A couple of days ago, I encountered the TC light coming on while driving and initially thought it was just a system glitch. Later, I figured out that TC stands for Traction Control. The yellow light mainly indicates two situations: one is normal intervention, like when tires slip during a turn on a rainy day, and the system automatically applies brakes to limit slippage; the other is an actual malfunction, where the entire anti-slip function might be disabled. Last time I took it to the repair shop, they found that the wheel speed sensor was clogged with mud, and it was fine after cleaning. If you see the light flashing a few times when turning on slippery roads, don't panic—it's the system helping you. However, if the light stays on continuously along with the engine warning light, you really need to get it checked immediately.
