What does it mean when the TC light on the dashboard is on?

When the TC light on the dashboard is illuminated, it indicates that the traction control system is active. During vehicle acceleration, if the system detects an excessive speed difference between the driving wheels and non-driving wheels, the computer will immediately determine that the driving force is too high and send a signal to reduce the engine's fuel supply, thereby decreasing the driving force and reducing the slip rate of the driving wheels. Another common indicator is the VSC light, which stands for Vehicle Stability Control system. This system significantly enhances vehicle handling safety and driving convenience. In emergency situations such as sharp turns, sudden acceleration, or hard braking, the vehicle can quickly detect these conditions and take appropriate braking measures, such as individually controlling each tire while reducing engine output to maintain vehicle stability.
