What's the reason for the ABS yellow light turning on and then disappearing after driving for a while?

When the ABS light in a car illuminates, it indicates a fault in the vehicle's ABS system. Below is an introduction to the automotive ABS system: Introduction: The Anti-lock Braking System, abbreviated as ABS, consists of components such as the ABS module, ABS master cylinder, oil pipes, and wheel speed sensors. During vehicle braking, it automatically controls the braking force to prevent wheel lock-up, maintaining a state where the wheels are both rolling and sliding (with a slip ratio of about 20%), ensuring maximum adhesion between the wheels and the road surface. Common Fault Points: A frequently encountered fault point is the malfunction of the ABS wheel speed sensor.
