How to turn off the TCS light?

Method to turn off the TCS light: It is recommended to promptly visit a professional repair shop for inspection and repair. The specific situation requires connecting a diagnostic tool to check the fault codes. Reasons for the TCS light being on: 1. Solenoid valve failure; 2. Dirty engine oil clogging the solenoid valve filter screen; 3. Wear of the actuator gear and impeller causing oil pressure leakage and triggering the alarm; 4. Dirty throttle with an opening reaching 20%. TCS stands for Traction Control System, and its function is to ensure the vehicle obtains optimal traction under various driving conditions. The control device of the Traction Control System is a computer that monitors the speed of the four wheels and the steering wheel angle. When the vehicle accelerates, if the computer detects an excessive speed difference between the drive wheels and non-drive wheels, it immediately determines that the driving force is too high and sends a signal to reduce the engine's fuel supply, thereby lowering the driving force and reducing the slip rate of the drive wheels.
I have a car that's been running for seven or eight years, and last month the TCS light came on, which was quite annoying. First, I checked the tire pressure and found one tire was underinflated, which might have triggered the system warning. Then, I flipped through the owner's manual, found the TCS button, and pressed it. When it didn't respond, I knew it might be a fault. I quickly drove to a nearby repair shop, where the mechanic used a diagnostic tool and found that the sensor wiring harness was loose. Reconnecting it solved the problem. The whole process taught me that when a light comes on, don't rush to dismiss it—confirm the cause first. Regular maintenance, like checking tire pressure and sensors, can prevent such issues. Safety first—don't skimp on small expenses and ignore warnings, or you might skid and crash on rainy days, leading to costlier repairs. Remember, a warning light is your car crying for help—fix it promptly to avoid bigger troubles.
