What does TC mean when it appears on the car's dashboard?

The appearance of TC on the car's dashboard indicates that the Traction Control system is active. TC stands for Traction Control System, which is designed to prevent wheel slippage. When braking or accelerating rapidly on slippery surfaces, wheels are prone to skidding, which can lead to loss of control and potential danger. To address such safety concerns, the Traction Control System was developed. TC relies on the electronic sensors of the ABS (Anti-lock Braking System). When it detects that the speed of the driven wheels is lower than that of the driving wheels, indicating wheel slippage, it sends a feedback signal to the car's system. The system then adjusts ignition timing, reduces throttle opening, decreases fuel supply, downshifts, or applies brakes to the wheels to prevent them from slipping.
Recently I noticed the TC light on the dashboard, which is actually quite common. TC stands for Traction Control. Its function is to automatically intervene when the tires slip, such as driving in rain or snow when the wheels are prone to losing control. The system helps by applying brakes or reducing throttle to stabilize the car. I often drive long distances, and when the light flashes briefly, it means the system is working. However, if it stays on continuously, there might be an electrical issue, requiring checks on sensors or fuses, otherwise it could affect braking safety. I suggest not panicking right away—refer to the owner’s manual to confirm the vehicle’s system, and if necessary, visit a repair shop to scan for fault codes. Maintaining proper traction control is crucial for driving stability, especially when going downhill or turning to avoid skidding.
