During inspection, how are the anti-lock braking system (ABS) brakes checked?

The proper inspection of the anti-lock braking system (ABS) begins with verifying that the warning light functions correctly. This light, usually located on the dashboard, alerts the driver to potential issues within the ABS. If the light remains illuminated after the vehicle is started, it indicates a malfunction in the ABS or its components that requires attention. Therefore, confirming that the warning light behaves as expected—illuminating during the initial startup and then turning off—signifies that the system is operating normally without any faults detected.

Ensuring the warning light functions properly is crucial because it serves as a primary method for monitoring the ABS’s health. Without this verification, drivers might be unaware of existing problems that could compromise braking effectiveness. This focus on the warning light is foundational in the general inspection practices for vehicle safety systems.
