What does the ABS light on the dashboard indicate?

The ABS light on the dashboard indicates a malfunction in the vehicle's Anti-lock Braking System. The working principle of ABS is: during emergency braking, it relies on highly sensitive wheel speed sensors installed on each wheel to detect wheel lock-up. The computer then controls the pressure regulator to release pressure from the wheel's brake cylinder, preventing wheel lock-up. The functions of the ABS system are: 1. To prevent loss of vehicle 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.
Seeing the ABS light on the dashboard really makes me nervous as a new car owner. ABS stands for Anti-lock Braking System, which prevents wheel lock-up during emergency braking. When the light comes on, it indicates a system malfunction - it could be dirty or faulty wheel speed sensors, poor wiring connections, or issues with the control module. Driving in rain or snow with this light on is particularly dangerous as wheels may skid during braking. Don't ignore this warning light; it's telling you to address the issue promptly. When I encounter this, I reduce speed, avoid sudden braking, and drive straight to a professional repair shop. They'll use diagnostic tools to read the trouble codes, identify the exact cause, and fix it properly. For regular maintenance, keep the sensors clean but avoid unnecessary disassembly.
