What does the TC indicator on the dashboard mean?

[ElleLynn]

The TC indicator stands for Traction Control system. When the TC light is on, it indicates that the traction control system is either turned off or there is a malfunction in the system. If you have ruled out the possibility of accidentally turning off the traction control switch, it means there is a fault in the vehicle's traction control system, and you should take it to a repair shop for diagnosis and repair. 1. How TC works: The TC system operates by using an electronic throttle control device to replace the mechanical connection between the accelerator pedal and the throttle. Sensors transmit the accelerator pedal's information to the ECU, which then generates a control voltage signal. The motor adjusts the throttle based on this signal to reduce the throttle opening and control wheel slip. 2. Causes of TC malfunction: (1) Solenoid valve failure; (2) Dirty engine oil clogging the solenoid valve filter; (3) Wear on the actuator gear and impeller causing oil pressure leakage and triggering an alarm; (4) Dirty throttle body with an opening reaching 20%, leading the engine computer to misjudge a TC fault.
