What to Do When the ABS Light in the Car Is On?
2 Answers
The ABS light in the car being on indicates a problem with the ABS system. It is recommended to have it checked at a repair shop. ABS stands for Anti-lock Braking System, which automatically controls the braking force during car braking to prevent the wheels from locking up, keeping them in a state of rolling and sliding (with a slip ratio of around 20%). This ensures maximum traction between the wheels and the road. Possible reasons for the ABS light being on include: 1. Faulty wheel speed sensor; 2. ABS wiring issues; 3. Malfunction in the ABS pump or pressure control solenoid valve; 4. Fault in the ABS computer. A continuously lit ABS light indicates an anti-lock braking system alert. Normally, the light turns on when the ignition is switched on or the engine is started, and the system enters an automatic detection program. The light should turn off after the detection is completed.
As soon as I see the ABS light come on in the car, I immediately know I need to be careful because this light indicates a problem with the anti-lock braking system. My first reaction is to slow down quickly and find a safe place to stop, avoiding high speeds. If the ABS fails, the tires may lock up during hard braking, making the car prone to skidding and losing control. For troubleshooting, I can start by restarting the engine to see if the light stays on. Sometimes, it's just a temporary computer glitch that resolves itself. Additionally, I can pop the hood and check the ABS fuse in the fuse box—if it's blown, replacing it costs just a dollar or two. If the light remains on, I suspect the wheel speed sensor might be dirty or clogged with mud, or there could be loose wiring. I wouldn’t dare to tinker with it myself—the braking system is too critical to take chances. I recommend driving straight to a nearby 4S shop or repair shop for professional diagnostics to pinpoint the exact issue. Regular driving habits like avoiding puddles and muddy areas, along with periodic sensor cleaning, can help prevent problems. In short, this warning light shouldn’t be ignored, and until fixed, driving with gentle braking is essential.
