What does the exclamation mark with a triangle illuminated on the car mean?

The exclamation mark with a triangle illuminated on the car refers to the traction control indicator warning light. The reasons for the light being on are: 1. Faulty oxygen sensor in the engine; 2. Clogged fuel injector; 3. Carbon buildup on the intake valve; 4. Faulty sensor; 5. Low fuel pressure; 6. Inaccurate air measurement; 7. Impurities in the gasoline. The functions of the traction control system are: 1. To provide the car with better traction under various driving conditions; 2. To improve driving stability, acceleration, and climbing ability. The working principle of the traction control system is: The computer detects the speed of the wheels and the steering angle of the steering wheel. When the car accelerates, if it detects that the speed difference between the drive wheels and non-drive wheels is too large, the computer will send a signal to reduce the fuel supply to the engine, thereby reducing the driving force.
Last time when I was driving, that red triangle warning light with an exclamation mark on the dashboard lit up. I know this usually indicates a problem with the braking system – it could be low brake fluid or an electronic component malfunction. I had to pull over to check because brake failure at high speeds is extremely dangerous. My usual procedure is to pop the hood and inspect the transparent brake fluid reservoir to see if the level is below the MIN line. If it's low, I top it up with DOT4 brake fluid. However, DIY repairs carry risks, so it's better to take it to a repair shop for professional inspection. I remember one rainy day when the light came on and the brakes felt spongy – terrifying! Turned out to be a minor part that had aged and was leaking fluid. Since then, I've been checking my braking system every six months as preventive maintenance. Bottom line: never ignore this warning light – safety first.
