What is the reason for the continuous illumination of both the ABS and anti-skid lights on the Sylphy?

[VonCalvin]

The simultaneous continuous illumination of the ABS and anti-skid lights on the Sylphy indicates a malfunction in the car's ABS system and anti-skid system. It could be due to a faulty sensor triggering the warning lights, requiring prompt inspection of both systems at a 4S shop to identify and repair the issue. A constant noise from the ABS pump is caused by an internal short circuit in the ABS pump control. Below are specific details about the ABS system: 1. Function of the ABS system: ABS is the anti-lock braking system, part of the car's active safety system. The ABS light illuminates when the vehicle's computer detects 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 high-speed hard stops, when the vehicle's computer determines the situation requires ABS intervention. When the ABS light comes on, it is often because the wheel speed sensors are not functioning properly. The ABS computer cannot detect the driving conditions of each wheel or compare the skid amounts of the wheels, preventing the ABS system from operating correctly.
