How to Solve the Problem of ABS Pump Continuously Making Noise?

Replace the ABS assembly. Below is a detailed introduction about the ABS pump: 1. Introduction: The Anti-lock Braking System (ABS) is designed to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling and sliding (with a slip ratio of about 20%), ensuring maximum adhesion between the wheels and the road surface. 2. Function: The ABS enhances the safety factor of emergency braking while driving. In other words, vehicles without ABS are more prone to wheel lock-up during emergency braking, which means the steering wheel cannot be turned, thereby increasing the risk and potentially leading to severe consequences.
Last time my car's ABS pump kept making a buzzing noise, which is actually quite a common issue. As an experienced driver, I've encountered this several times. Most likely it's due to dirty sensors or loose wiring causing the pump to operate continuously. You can try checking it yourself: restart the engine after turning it off, sometimes this can help; check the battery voltage as low voltage can cause ABS malfunctions; inspect the headlight or ABS fuse in the fuse box - if it's blown, try replacing it with a new one. If the noise persists non-stop, don't delay - take it to a professional repair shop. If the ABS malfunctions, the anti-lock braking function fails during emergency stops, posing significant safety risks. During regular maintenance, pay extra attention to brake fluid levels and cleanliness - prevention is key. I once neglected this and ended up with the ABS light on and noise while driving, but fortunately dealt with it promptly and avoided an accident. Remember, don't wait until the problem escalates before taking action.
The issue of the ABS pump continuously making noise should be examined from a systemic perspective. Possible causes include air in the hydraulic system causing the pump to run dry, a faulty wheel speed sensor sending incorrect signals that keep the pump running, or a damaged relay. First, try simple solutions: turn off the car, wait a few minutes, and restart to allow the system to reset; check the brake fluid level and top it up if low, bleeding the system if necessary. However, bleeding is best left to experienced hands, as it requires specialized tools. If the noise is accompanied by the ABS warning light, promptly read the fault codes to identify the root cause. Safety first—attempting DIY repairs may damage the vehicle, so it's best to visit a 4S shop or professional repair center. They can test the pump pressure and related components, such as cleaning sensors or replacing damaged parts. In the long term, avoid sudden acceleration and braking to reduce system stress.
I always pay attention to maintenance while driving to prevent problems. The ABS pump noise is usually caused by improper use or aging, such as frequent hard braking leading to hydraulic overload, or long-term failure to replace brake fluid resulting in air bubbles. Prevention is key: regularly check the brake fluid level to ensure it's at the max line; replace the brake fluid approximately every 20,000 kilometers; avoid driving through waterlogged areas to prevent sensor corrosion. If the pump starts making noise, first pull over to check, and try restarting to see if it resolves the issue. If not, go directly for repairs without delay. The ABS system is crucial for safety, and continuous pump noise can slow down brake response, increasing the risk of accidents. Adding some extra checks during regular maintenance can save a lot of money. Simple maintenance can extend the lifespan of components.
