If the ABS Warning Light is on and remains on, what does this indicate?

When the ABS warning light is illuminated and remains on, it signifies that there is a fault within the Anti-lock Braking System (ABS) that has caused the system to become disabled. This warning means that the ABS is not operational, which is a safety concern. The ABS is designed to prevent wheel lock-up during braking, particularly in slippery conditions, so a malfunction could significantly affect vehicle safety.

In this situation, further diagnostics are required to identify the specific issue or fault within the system. The warning light serves as an alert for the driver to investigate the problem, which could involve checking system components, sensors, or the ABS control module. Addressing the issue promptly is crucial to restore normal braking function.

Other options suggest that the ABS system might be functioning well or that the issues are not significant, which is not the case when the warning light is continuously illuminated. Additionally, a reset light is generally not a solution for an ongoing fault; that action would typically follow after a confirmed repair.
