If your anti-lock braking system light comes on briefly when you start the car, what does it indicate?

When the anti-lock braking system (ABS) light comes on briefly when you start the car, it indicates that the ABS system is working properly. This brief illumination is a normal part of the system's self-check process during the vehicle's startup. The ABS performs a diagnostic to confirm that all components are functioning as they should, and if everything is in order, the light will turn off shortly after the engine starts. This self-test ensures that the braking system will be ready to provide optimal performance in various driving conditions.

If the ABS light remains on after startup or if it illuminates while driving, that could suggest a malfunction or issue that needs attention. Therefore, a brief illumination at startup is a sign of a functioning system rather than a problem requiring repair.
