What happened to the tc light?

The indicator "TC" on the dashboard corresponds to the traction control system, also known as the tracking control system. The light may be on because it accidentally touched the traction control switch next to the gear lever and turned off the traction control system. If the misoperation is eliminated, it can only indicate that the traction control system is faulty.

Causes of traction control system failure:

1, solenoid valve failure;

2. The oil is dirty, blocking the filter screen of the solenoid valve;

3, actuator gear and impeller wear caused by oil pressure leakage and alarm;

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

The working principle of traction control system is to replace the mechanical connection between accelerator pedal and accelerator with electronic accelerator device. The sensor transmits the information of the accelerator pedal to the ECU, and the ECU generates a control voltage signal according to the signal, and the servo motor adjusts the accelerator according to the signal, so as to reduce the accelerator opening and control the tire skid.
