What is the reason for the anti-lock braking system being in the on state?

The anti-lock braking system being in the on state does not display an icon; the dashboard will only show an icon when the system is turned off or malfunctions, which is the ABS indicator. This may vary slightly depending on the vehicle model. The anti-lock braking system, abbreviated as ABS, can automatically control the vehicle's braking force through the computer. While braking, the wheels do not lock up, enhancing the adhesion between the wheels and the ground. After the system is activated, the vehicle's steering wheel can still be turned, thereby reducing the risk factor and effectively minimizing accidents. The functions of the anti-lock braking system: It can effectively shorten the braking distance and time, prevent the vehicle from skidding or fishtailing during emergency braking, ensure driving safety, reduce tire wear, effectively enhance the friction between the tires and the ground, and provide steering control capability when the system is active, thereby reducing or avoiding accidents.
The anti-lock braking system (ABS) staying constantly activated is most commonly caused by sensor issues, such as wheel speed sensors being dirty or malfunctioning, which tricks the system into thinking the wheels are about to lock up. Another frequent culprit is control module failure - when this component fails, the ABS mistakenly believes the vehicle is in a constant emergency braking situation. I've encountered numerous cases during repairs where aged wiring or poor connections further confuse the system. The ABS is designed to activate only during hard braking to prevent skidding, but constant activation can actually interfere with normal braking, potentially increasing stopping distances or creating strange pedal feedback - which is quite unsafe. I recommend first checking the fuses and battery connections yourself. If that doesn't resolve it, take the vehicle to a professional repair shop immediately before the issue escalates into something more serious.
