What does it indicate if the ABS light illuminates for a few seconds at startup?

When the ABS light illuminates for a few seconds during startup, it indicates that the Anti-lock Braking System is performing a self-check and is functioning as intended. This is a standard procedure for vehicles equipped with ABS. When the system successfully completes its self-diagnostic test, the light will turn off, confirming that the ABS is operational and there are no issues present at that moment.

If there were a problem with the ABS, the light would stay on after the initial startup check. Lighting up briefly is not an indication of malfunction; rather, it reassures the driver that the system is functioning properly. The ABS light serves as an important indicator, letting drivers know when they can expect optimal brake performance, especially in slippery conditions.
