How to eliminate the ABS light after vehicle annual inspection?

After the annual inspection, the ABS light will automatically turn off after driving a certain distance. For front-wheel drive and rear-wheel drive vehicles, during the tailpipe emission test, only the drive wheels rotate while the non-drive wheels remain stationary. At this point, the ABS system may misinterpret this as a wheel speed sensor malfunction, causing the ABS warning light to illuminate. After the inspection, once the vehicle is driven on the road for a while, the ABS light will go off. ABS stands for Anti-lock Braking System, a vehicle safety control system with advantages like anti-skid and anti-lock features. It is an enhanced technology based on conventional braking systems and can be categorized into mechanical and electronic types.
After my last annual inspection, the ABS light also came on, which made me a bit worried while driving. I asked a mechanic friend, and he said it's quite common—the inspection equipment might interfere with the signal system. He suggested I first drive for about 5 to 10 kilometers to see if the system resets itself and the light turns off. If it doesn’t, check the fuse box: locate the ABS fuse under the hood (the manual has a diagram), pull it out, and see if it’s burnt or broken. Replacing it is simple and affordable. Cleaning the sensors near the wheels is also important—use a soft cloth to wipe off dust and grease, and make sure no water accumulates. If the light remains on, it could be a wiring issue or uncleared fault codes. It’s best to connect an OBD scanner to read and clear the codes; these tools aren’t expensive online. Remember, don’t ignore this warning—ABS failure can affect braking safety, especially on mountain roads or in rainy weather. Regular maintenance and paying attention to the sensor areas during car washes can help prevent issues.
After the annual inspection, the ABS light suddenly came on, which is something I often deal with myself. The solution is simple: first, drive at low speed for a few laps to let the system reset itself. If the light goes off, it means it was just temporary interference and nothing to worry about. If it doesn’t go off, check the fuse—open the fuse box in the cabin or under the hood, refer to the manual for the ABS label, and check if it’s loose or blown. Replacing one costs just a few bucks. Cleaning the wheel speed sensor is also crucial. After parking, go to the wheel and gently wipe the probe with your finger or a cloth to remove dirt and avoid mud buildup. Don’t rush the process with technical jargon; it only takes a few minutes. If the light stays on, it’s best to use an OBD scanner to clear the fault code or visit a nearby shop to have a technician read and clear it. To prevent annual inspections from triggering issues, avoid parking near puddles or dusty areas—saving money, time, and peace of mind.
My car's ABS light came on right after the annual inspection. Based on experience, the light went off by itself after driving for a few minutes. I asked in the car owners' group, and they all suggested trying to reset the system by test driving. If the light doesn't go out, it might be due to dirty sensors or a fuse issue, requiring cleaning or replacement. Don't worry, it's a minor problem, but it must be addressed to avoid potential braking hazards.
