Is it true that the ABS light being on indicates a failure of the brake system?

The ABS (Anti-lock Braking System) light being on does not inherently indicate a complete failure of the brake system. Instead, it signifies that there is a problem with the ABS itself, which is a separate component of the overall brake system. The ABS is designed to prevent the wheels from locking up during heavy braking, which helps maintain traction and control.

When the ABS light activates, it usually means that the system is not functioning properly and might require diagnostics to determine the specific issue. However, it's essential to note that the vehicle may still have normal braking function through the traditional braking system. Therefore, while the ABS light being illuminated indicates a potential issue, it does not necessarily point to a total failure of the brake system.

It’s also important to differentiate between the ABS light's implications versus warnings related to the brake system itself, which may have their own warning lights. Understanding this distinction helps drivers take appropriate actions—such as seeking inspection and repairs for the ABS without assuming that the entire brake system is compromised.
