What does the yellow TC light on the dashboard mean?
1 Answers
The "TC" indicator light on the dashboard corresponds to the Traction Control System, also known as the Traction Control System. The reason for this light to illuminate may be due to accidentally touching the traction control switch next to the gear shift lever, simply turning off the traction control system can resolve it. If accidental contact is ruled out, it can only indicate a fault in the traction control system. Here are the relevant introductions: 1. The role of the traction control system: The role of the traction control system is to ensure that the car can obtain the best traction under various driving conditions. A fault in the traction control system is not a small problem and should not be ignored. It requires timely repair. 2. Reasons for traction control system failure: Electromagnetic valve failure; dirty oil clogging the electromagnetic valve filter; wear of the actuator gear and impeller leading to oil pressure leakage and triggering an alarm; dirty throttle, opening reaching 20%, causing the engine computer to mistakenly judge a TC fault. 3. Working principle: The working principle of the traction control system is to replace the mechanical connection between the throttle pedal and the throttle with an electronically controlled throttle device. The sensor transmits the throttle pedal information to the ECU, which then generates a control voltage signal based on the signal. The servo motor adjusts the throttle according to this signal to reduce the throttle opening and control tire slip.
