ABS light coming on is quite simple, even pulling out the ABS fuse will cause the warning light to illuminate. Once the ABS warning light comes on, it will not turn off by itself. Even if the ABS returns to normal, the light will not go out. Therefore, specific steps must be taken to reset the warning light. There are 2 methods, as detailed below: 1. Visit a repair shop to have the light cleared using a diagnostic computer. 2. You can perform the reset yourself. Locate the car battery, disconnect the negative terminal, wait a few minutes, then reconnect it. The ABS warning light should turn off. 3. Try performing a reset of the vehicle's computer system. Turn off the engine, wait a few minutes, then restart. This process allows the system to reinitialize sensor data integration. It is recommended to have a certified technician inspect the system and perform a full diagnostic scan of the vehicle's computer.

I found that the ABS warning light should never be ignored as it relates directly to braking safety. First, you can check the brake fluid level yourself - if it's too low, top it up. Then inspect whether the wheel speed sensors on all four wheels are covered by mud or metal shavings, as debris can interfere with the signal. Last time my friend's car had the light on, this was precisely the reason. Additionally, inconsistent tire pressure might also trigger false fault reports. If the light remains on after simple cleaning, you'll need to use a diagnostic tool to read the trouble codes. Problems with the ABS control unit or damaged sensor wiring require professional repair. I remember once when the light came on during highway driving, I immediately reduced speed and checked at the nearest service area - such issues should never be delayed.

Last week, I encountered a situation where the ABS warning light came on, so I immediately pulled over to check. During regular maintenance, I always pay special attention to cleaning the wheel speed sensors, but this time the issue was due to air entering the brake system. I followed the manual to bleed the air, and the light went off. However, most of the time, it requires a visit to the repair shop. If the ABS module or sensors are damaged, they can only be replaced with new parts. I've heard of cases where modified cars had improper wiring, causing the light to stay on constantly. In daily driving, it's best to avoid deep water roads, as water entering the sensors can easily cause a short circuit. It's a good habit to wipe the sensor areas every time you wash the car.

The ABS light typically indicates an issue with the anti-lock braking system. Experienced technicians usually check the trouble codes first: Codes starting with C often indicate circuit problems, while U codes point to communication faults. A common issue is wheel speed sensor failure - last time in my car, the ABS light came on because a mouse chewed through the left front wheel sensor wire. Additionally, damaged tone rings or worn bearings can affect the signal. OEM sensors cost over 300 yuan, while aftermarket ones are around 100 yuan but have shorter lifespans. During maintenance, having the mechanic perform an active test with a diagnostic tool is the most reliable approach.
