How to Resolve the ABS Warning Light Issue?
2 Answers
The solutions for the ABS warning light being on are: 1. Check for poor contact or damage in the wiring and connectors; 2. Inspect the installation gap, position, and contamination of the wheel speed sensor and toothed ring; 3. Avoid high-speed driving and sudden braking; 4. Adjust the wheel bearing clearance to the normal value. The functions of the ABS system are: 1. To prevent vehicle loss of control, increase braking distance, and improve vehicle safety; 2. To enhance the overall braking performance of the vehicle; 3. To prevent wheel lock-up during braking; 4. To ensure the driver can control the direction during braking and prevent rear axle skidding. The working principle of ABS is: During emergency braking, the highly sensitive wheel speed sensors installed on each wheel detect wheel lock-up, and the computer immediately controls the pressure regulator to release pressure from the wheel's brake cylinder, preventing wheel lock-up.
I remember last time the ABS light came on, my friend taught me to first pull over and check the brake fluid level, topping it up if it's low. Then wipe the probes on the inner side of all four wheels with a tissue—sometimes mud can block the sensors. This trick actually worked; once after driving on mountain roads, the light went off. If that doesn't help, you'll need to go to a repair shop to connect to the computer and check the fault codes. Most likely, it's a faulty wheel speed sensor, and replacing a new one only costs around a hundred bucks. When washing your car, pay attention to rinsing the inner side of the wheel hubs to prevent sensors from getting clogged with metal shavings. When ABS fails, the brakes will feel harder, so leave more distance from the car in front during rainy days. It's safer not to drive on the highway until it's fixed.
