What does the ABS light on the dashboard indicate?

[Mark]

The illumination of the ABS light on the dashboard indicates a malfunction in the Anti-lock Braking System. The function of the Anti-lock Braking System is to automatically control the braking force during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling and sliding, thereby ensuring maximum adhesion between the wheels and the road surface. The control channels of the Anti-lock Braking System are categorized into four-channel, three-channel, two-channel, and one-channel systems. A four-channel ABS has four wheel speed sensors, each equipped with a brake pressure regulator in the pipelines leading to the brake cylinders of the four wheels for independent control. A three-channel ABS independently controls the two front wheels while jointly controlling the two rear wheels based on the low-select principle. A two-channel ABS struggles to balance directional stability, steering control, and braking efficiency, and is rarely used nowadays. A one-channel ABS, often referred to as a single-channel ABS, has a brake pressure regulator installed in the rear wheel brake main pipe and a wheel speed sensor mounted on the rear axle main reducer.
