What indicates a malfunction in the ABS system?

• A. A sound from the engine
• B. A dashboard ABS warning light
• C. The brake pedal feeling soft
• D. The steering wheel vibrating

Answer: (B)

The presence of a dashboard ABS warning light is a direct indication of a malfunction in the Anti-lock Braking System (ABS). This warning light is specifically designed to alert the driver when there is an issue with the braking system, particularly with components related to the ABS. When the ABS system functions properly, the warning light remains off. However, if there are faults such as sensor malfunctions, loss of hydraulic pressure, or internal faults within the ABS module, the light activates, signifying that the system may not be able to function effectively. While sounds from the engine, a soft brake pedal, or a vibrating steering wheel could indicate problems related to the vehicle’s overall braking system or other mechanical issues, these symptoms are not exclusive or specific to the ABS. Thus, they may point to various other concerns that require attention but do not specifically confirm a malfunction within the ABS system itself.
