What Causes the ABS Pump to Keep Making Noise?

[McMicah]

ABS pump continuously making noise is caused by an internal control short circuit in the ABS pump. Below are the specific details about the ABS system: 1. Function of the ABS System: ABS stands for Anti-lock Braking System, which is part of the vehicle's active safety systems. When the ABS light comes on, it indicates that the vehicle's computer has detected a fault in the ABS system. 2. Principle of the ABS Light: Under normal driving conditions, the ABS remains in a dormant state. It only activates during emergency braking, such as when braking hard at high speeds. The vehicle's computer determines when the ABS should intervene. When the ABS light comes on, it is often due to the wheel speed sensors not functioning properly. The ABS computer cannot detect the driving conditions of each wheel, making it impossible to compare the slip amounts of the wheels, which results in the ABS system failing to operate correctly.
