What does displaying TC mean?

Displaying TC refers to the Traction Control System, with TC being the abbreviation for Traction-Control-System. Below is an introduction to the functions of the Traction Control System: 1. It enables the vehicle to achieve optimal traction under various driving conditions. 2. It indicates that the traction control switch next to the gear shift lever is turned off. 3. If accidental pressing is ruled out, it indicates a fault in the Traction Control System. There are several reasons why the TC light may illuminate: 1. Faulty solenoid valve. 2. Dirty engine oil clogging the solenoid valve filter screen. 3. Wear and tear on the actuator gears and impeller causing oil pressure leakage, leading to an alarm. 4. Dirty throttle body, with an opening reaching 20%, causing the engine computer to misjudge a TC fault.
Once during a heavy rainstorm while driving, I suddenly saw the yellow TC light pop up on the dashboard and was completely confused. Later at the repair shop, the mechanic explained that TC stands for Traction Control System—it's like an invisible bodyguard. When wheels slip on wet roads, it automatically reduces engine power or applies brakes individually to the slipping wheels to prevent the car from losing control. That day on the highway when I encountered standing water, the TC light was flashing like crazy, indicating it was constantly adjusting tire grip. If this light stays on continuously, it might mean the sensor is clogged with mud or there's a system malfunction that needs checking. Whenever I drive on mountain roads and feel the tires getting a bit floaty during sharp turns, I always pay extra attention to the TC light's status.
