How to solve the ABS system check issue?

[JulianRose]

ABS stands for Anti-lock Braking System. The prompt to check the ABS system indicates there's an issue with it. The ABS light should briefly illuminate for a few seconds during startup for system self-check and automatically turn off if no problems are detected. During driving, if you stomp the brake pedal abruptly, the ABS light may activate, but it should turn off when you release the brake. A constantly illuminated ABS light means the system has detected an error, which directly impacts driving safety - immediate repair at a service center is required. Here are detailed explanations about the ABS system: 1. ABS system function: ABS is a vehicle anti-lock braking system, belonging to active safety systems. When the ABS light stays on, it means the vehicle's computer has identified a fault in the ABS system. 2. ABS light activation principle: Under normal driving conditions, the ABS remains dormant. It only activates during emergency braking situations (like hard braking at high speeds) when the vehicle computer determines intervention is needed. Most ABS light activations occur when wheel speed sensors malfunction, preventing the ABS computer from detecting each wheel's movement and comparing slippage rates, thus rendering the ABS system inoperable.
