What does TC on the car dashboard mean?

TC on the car dashboard stands for Traction Control System. The Traction Control System, also known as the Track Control System, relies on electronic sensors to detect when the driven wheels' speed is lower than that of the driving wheels. It then sends signals to adjust ignition timing, reduce throttle opening, decrease fuel supply, downshift, or brake the wheels to prevent wheel slippage. Reasons for the TC light on the car dashboard to illuminate include: 1. Solenoid valve malfunction; 2. Dirty engine oil clogging the solenoid valve filter; 3. Wear of the actuator gears and impeller causing oil pressure leakage and triggering an alarm; 4. Dirty throttle body with an opening reaching 20%, leading the engine computer to mistakenly diagnose a TC fault.
As an experienced driver who frequently drives, I always pay attention to the information on the dashboard. TC stands for Traction Control System, which is mainly used to prevent wheel slippage, such as on rainy, snowy, or slippery roads. If the light flashes, it means the system is actively intervening; but if it stays on constantly, it's likely that the system has been manually turned off or there is a malfunction, such as a broken sensor. In this case, I would drive at a reduced speed, avoid sharp turns, and check if the TC switch was accidentally pressed in the car. If not resolved, it could lead to more serious problems, as safety-related systems should not be taken lightly. I also recommend everyone to have the entire system checked during regular maintenance to ensure safer driving in winter.
I'm a car enthusiast with a special interest in automotive electronic systems. TC stands for Traction Control, which automatically monitors wheel speed and reduces engine power or applies braking to maintain vehicle stability when it detects a risk of wheel slip. When the dashboard light is on, flashing indicates the system is active; if it stays lit constantly, there may be an issue with the circuit or relay. I've tried checking the manual to locate the problem myself, but it's recommended to seek professional diagnosis to avoid affecting other safety components like ABS. Maintaining proper tire pressure is also important to reduce false system triggers.
