What is the difference between the ABS red light and yellow light?

[Sophia]

Yellow light indicates a malfunction in the ABS system, while the red light means the ABS system is activating. Below is more information about ABS: 1. Function: Its role is to automatically control the braking force during car braking, preventing the wheels from locking up and keeping them in a state of rolling and sliding (with a slip ratio of about 20%), ensuring maximum adhesion between the wheels and the ground. 2. Development History: The development of ABS systems can be traced back to the early 20th century. By the late 1970s, the rapid advancement of digital electronic technology and large-scale integrated circuits laid the technical foundation for the practical development of ABS systems, leading many companies to successively develop various forms of ABS systems.
