Does the ABS light being on indicate that the anti-lock braking system is activated?

The ABS light being on does not indicate that the anti-lock braking system is activated. When the anti-lock system light is on during startup, it is part of the system's self-check function. If the light remains on after startup or comes on while driving, it indicates a system malfunction, and the anti-lock braking system should be inspected at a repair station as soon as possible. The anti-lock braking system, abbreviated as ABS, functions by automatically controlling the braking force during vehicle braking to prevent wheel lock-up, keeping the wheels in a state of rolling and sliding (with a slip rate of about 20%) to ensure maximum traction between the wheels and the road surface. Reasons for the ABS light being on: 1. Engine start or ignition: Most modern vehicles are equipped with an ABS system, and the ABS light may illuminate during engine start or when the ignition switch is turned on. This is a normal phenomenon and does not affect the vehicle. 2. Ignition switch or startup: Under normal conditions, the light will come on when the ignition switch is turned on or the engine is started, as the system enters an automatic check procedure. The light will turn off once the check is completed.
