What does the yellow TC warning light in a vehicle mean?

The yellow TC light in a car indicates that there may be a fault in the traction control system. TC stands for Traction Control. If the traction control switch next to the gear lever is turned off, the indicator light will also illuminate. If you have ruled out the possibility of accidentally turning it off yourself, it means there is a fault in the traction control system, and you need to take the car to a repair shop for inspection and maintenance. The function of the traction control system is to provide the best traction for the car under various driving conditions, improving the vehicle's passability. For example, when the ABS anti-lock braking system detects that some wheels are slipping, it will apply braking to the slipping wheels to prevent the loss of traction on those wheels. The working principle of the traction control system is to replace the mechanical connection between the accelerator pedal and the throttle with an electronic throttle control device. Sensors transmit the information from the accelerator pedal to the ECU, which then generates a control voltage signal based on this information. The servo motor adjusts the throttle according to the signal, thereby reducing the throttle opening and controlling wheel slip. For vehicle owners driving in rainy or snowy conditions, this can reduce occurrences of wheel slip or loss of control.
