What is the reason why the ABS light is on and the car cannot move?

[MacConnor]

When the ABS light of a car stays on, it indicates that there is a fault in the ABS system. ABS refers to the Anti-lock Braking System of the car, which continuously monitors the wheels of the vehicle to ensure that they turn at exactly the same speed. During braking, the ABS system uses the brake to control the amount of braking force. A continuous noise from the ABS pump is caused by an internal short circuit in the ABS pump. Below is a detailed introduction to the ABS system: 1. Function of the ABS system: ABS is the vehicle's Anti-lock Braking System, which is part of the car's active safety system. When the ABS light is on, it means that the car's computer has detected a fault in the ABS system. 2. Principle of the ABS light: Under normal driving conditions, the ABS remains dormant. It only activates during emergency braking, such as when braking hard at high speeds, when the car's computer determines that ABS intervention is necessary. When the ABS light is on, it is often due to the wheel speed sensor not functioning properly. The ABS computer cannot detect the driving conditions of each wheel and cannot compare the slippage of each wheel, resulting in the ABS system not functioning properly.
