How to Solve the ABS Warning Light Issue?

When the ABS warning light comes on, it is necessary to promptly send the vehicle to a repair station for maintenance. Related information: 1. ABS: ABS stands for Anti-lock Braking System, a technology developed by Robert Bosch GmbH for use in motorcycles and cars to prevent loss of control and generally increase braking distance, thereby improving vehicle safety. The function of ABS is to automatically control the braking force during vehicle braking, preventing the wheels from locking up and ensuring maximum traction between the wheels and the road. 2. ABS working principle: It utilizes a rubber airbag inside the valve body. When the brake is pressed, brake fluid pressure is applied, filling the ABS valve body. The airbag then uses an intermediate air layer to return the pressure, helping the wheels avoid the lock-up point. When the wheels are about to reach the next lock-up point, the brake fluid pressure causes the airbag to repeat the process, acting 8-30 times per second, equivalent to continuous braking and releasing, similar to mechanical 'cadence braking'.
When the ABS warning light comes on, it can be quite alarming. I've encountered this situation a few times, and while it's usually not a major issue, it should never be ignored. Possible causes include a dirty or snow-covered wheel speed sensor, loose wiring connections, or a minor fault in the control unit. My approach is to first find a safe place to pull over and restart the engine to see if the light goes off. If it remains on, check the fuse box for any blown fuses or simply clean the dust around the wheel hubs. Remember, the ABS is crucial for preventing wheel lock-up during braking, especially when driving in rain or snow—losing it increases the risk of skidding. So, don’t delay; it’s best to visit a professional repair shop as soon as possible for diagnosis to prevent small issues from escalating. During routine maintenance, remind the mechanic to check these components—it can save a lot of trouble.
