What does TC displayed in the car mean?

The appearance of TC in the car indicates that the Traction Control System is active. Here is some relevant information about the Traction Control System: 1. The Traction Control System, also known as the Track Control System or Anti-Slip Regulation System, is part of the vehicle's active safety systems. It is a slip control system adopted after ABS and serves as a further development and important supplement to ABS functionality. While the functionality of the Traction Control System is the same across different manufacturers, the names vary. For example: Mercedes-Benz calls it ASR, Toyota calls it TRC, BMW calls it DTC, and Cadillac calls it TCS. 2. TCS is the abbreviation for Traction Control System; ASR stands for Acceleration Slip Regulation. When braking on slippery surfaces, the wheels may skid, potentially causing loss of directional control. Similarly, during acceleration or rapid acceleration, the drive wheels may also skid, leading to dangerous loss of control on icy or other slippery surfaces. The Traction Control System is designed to address such issues.
I recently had the TC light come on in my car, which gave me quite a scare, so I quickly looked it up. TC stands for Traction Control, meaning the car is helping prevent tire slippage, especially on rainy, snowy, or muddy roads. If it lights up and then goes off, that's normal operation; but if it stays on continuously, it could indicate a system malfunction or that it was manually turned off. Common causes include dirty sensors, wiring issues, or unstable battery voltage. For safety, whenever I see it light up, I slow down and find a safe place to pull over to check the manual or try restarting the engine. Ignoring it long-term might lead to loss of control in emergencies, so I recommend checking electronic system components during regular maintenance.
