ABS light being on does not prevent a car from passing the annual inspection. ABS, short for Antilock Brake System, functions by automatically regulating the braking force during vehicle deceleration to prevent wheel lock-up. It maintains the wheels in a state of rolling and sliding (with a slip ratio of approximately 20%), ensuring maximum traction between the tires and the road surface. Functions of ABS: Maximizes braking efficiency, reducing braking time and distance. Effectively prevents vehicle skidding and fishtailing during emergency braking, ensuring stable driving performance. Allows steering during emergency braking, enhancing maneuverability. Minimizes intense friction between tires and the road surface, reducing tire wear. Working Principle of ABS: During braking, ABS rapidly assesses the wheel lock-up status based on signals from each wheel speed sensor. It then closes the normally open input solenoid valve for the wheel starting to lock, maintaining consistent braking force. If the wheel continues to lock, the normally closed output solenoid valve opens, rapidly decreasing the braking pressure on that wheel by diverting brake fluid directly to the reservoir, thus preventing complete wheel lock-up due to excessive braking force. This ensures the braking system operates at the optimal point (with a slip ratio S of 20%), delivering the best braking performance and maximum driving safety.

Having driven for 15 years, I can confirm that an illuminated ABS light will indeed affect the annual inspection pass rate. The ABS system is a crucial component of the braking system, and during the annual inspection, the vehicle's safety functions, including brake testing, are thoroughly examined. If the light is on, it indicates that the anti-lock braking function has failed, which may cause the wheels to lock up and skid during braking, increasing the risk of accidents. I remember last year when my own car's ABS light came on, the inspector immediately pointed out that the fault code made it unqualified. I promptly went to a repair shop and found that the sensor was faulty. After spending a few hundred yuan to fix it, I passed the inspection smoothly. So, safety comes first—don't ignore it. Timely diagnosis of the issue is more reliable, and you shouldn't wait until problems arise to regret it. Common causes include poor sensor contact or aging wiring. After checking, test drive the car to ensure the light is off before proceeding.

The ABS light suddenly came on, and I was really nervous, especially since I just got my driver's license and was worried about failing the annual inspection. I heard from a friend that the inspection standards are strict, and an illuminated ABS light indicates a system error, meaning the braking performance isn't guaranteed, so it would definitely be marked as a fail during the check. I looked up some posts online and found many people sharing similar experiences: if the light is on and not fixed, the vehicle inspection station would reject it outright. I quickly scheduled a check at the 4S store and found out the ABS module was faulty. My advice is to deal with it as soon as possible to avoid any surprises—don’t wait until the night before the inspection like I did, scrambling at the last minute.

I'm an auto mechanic. When the ABS light comes on, it usually indicates a system malfunction, such as issues with sensors or the pump. During annual inspections, they focus on brake functionality, and the light being on might cause a failure since national regulations require ABS to be operational. During actual inspections, the diagnostic tool reading fault codes can pinpoint the issue. Don't underestimate it—ABS prevents wheel lock-up during hard braking, improving control. Try resetting the system yourself; if that doesn't work, take it to a professional shop for diagnosis. Most likely, a small expense for part replacement will fix it.

As a parent of two children, the car is just a means of transportation. When the ABS light comes on, I worry more about safety, and it would be a big problem if it affects the annual inspection. The inspector will test the brake response, and if the ABS light is on, it indicates a system defect, which will definitely be recorded as a failure. Last time the light came on, I went to a roadside shop for inspection, spent some time repairing the wiring, and then passed the annual inspection. I suggest not taking the risk of driving with the light on—fix it first. Family safety is much more important than money.

In recent years, while modifying cars, I've had the ABS light come on a few times—lessons learned the hard way. It directly affects braking stability and makes it easy to fail the annual inspection. ABS is a mandatory check, and a lit light indicates a fault, which is considered a safety threat and will result in failure. When I dealt with it, I simply replaced the sensor, which wasn't costly. Remember, having the system functioning properly with the light off is a strict requirement—don't cut corners. Addressing it before the inspection saves hassle.
