What does the TC light on the car mean?

[LeTimothy]

The TC light on the car stands for the Traction Control system. When the TC light is illuminated, it indicates that the Traction Control system is active. During acceleration, if the system detects a significant speed difference between the drive wheels and non-drive wheels, the computer will immediately determine that the driving force is excessive and send a signal to reduce the engine's fuel supply, thereby decreasing the driving force and reducing the slip rate of the drive wheels. The working principle of TC is: replacing the mechanical connection between the accelerator pedal and the throttle with an electronic throttle control device. Sensors transmit the accelerator pedal's information to the ECU, which generates a control voltage signal based on the input. The servo motor then adjusts the throttle according to this signal, reducing the throttle opening and controlling wheel slip. For vehicle owners driving in rainy or snowy conditions, this system can help reduce occurrences of wheel slip or loss of control.
