What's wrong with tc lamp? What does the car tc fault light mean?

The tc light is on, indicating that the traction control system is faulty.

Four reasons for failure of tc lamp:

1, solenoid valve failure.

2. The oil is dirty and blocks the filter screen of the solenoid valve.

3. Wear of the gear and impeller of the actuator leads to oil pressure leakage and gives an alarm.

4. The dirty throttle opening reaches 20%, and the engine computer misjudges TC fault.

Extended data:

Traction control system can not only improve the driving stability of the vehicle, but also improve the acceleration and climbing ability of the vehicle. Traction control system is only installed in luxury cars.

If the traction control system is combined with ABS, the safety of the vehicle will be further improved. Traction control system and ABS can use the wheel speed sensor on the axle and connect with the driving computer to continuously monitor the wheel speed. When low-speed slip is found, the traction control system will immediately inform ABS to take measures to reduce wheel slip.

When high-speed sideslip is found, the traction control system will immediately send a command to the driving computer, instructing the engine to slow down or the transmission to downshift, so that the pulley will no longer slip and prevent the vehicle from losing control and tail flick.
