How to Deal with the ABS Light Staying On?
2 Answers
Methods to address the ABS light staying on: 1. Check the wiring connection between the wheel speed sensor and the ABS control unit; 2. Inspect the installation gap and position of the wheel speed sensor and the toothed ring, as well as any contamination by dust or debris; 3. Check if the wheel bearing clearance is too large; 4. The sensor itself may be faulty. The Anti-lock Braking System, abbreviated as ABS, functions to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling and sliding. This ensures maximum adhesion between the wheels and the road surface. ABS is an improved technology based on conventional braking systems and can be categorized into mechanical and electronic types.
I've driven quite a few cars and encountered situations where the ABS light came on. This usually isn't a major issue but should be taken seriously. The most common reason is that the wheel speed sensor is dirty or blocked by debris, since ABS relies on these sensors to detect wheel rotation speed and prevent brake lock-up. You can check yourself to see if there's mud or ice covering the sensor on the inner side of the wheel - cleaning it off might make the light go away. If the light remains after cleaning, it could mean the sensor is faulty, a fuse is blown, or there's an issue with the ABS pump, requiring a diagnostic scan tool to read the trouble codes. Don't ignore this light as it's directly related to braking safety. It's best to get it checked at a shop before long trips to avoid brake failure at critical moments. Safety first - don't push your luck, address it promptly and it can always be resolved.
