How can you tell if your vehicle is equipped with anti-lock brakes?

A yellow ABS light illuminating during the light check is a reliable indicator that the vehicle is equipped with anti-lock brakes. This light serves as part of the vehicle's onboard diagnostic system, specifically indicating that the anti-lock braking system is present and is functioning properly. When you start your vehicle, this light should illuminate briefly as part of the self-check routine before turning off. If it stays on or comes on while driving, it could indicate a problem with the ABS.

The user manual can provide information about the vehicle’s features, including the presence of ABS, but identifying the ABS system through the dash light is a quicker, more immediate method. The absence of pedal resistance might suggest other mechanical issues rather than specific functionality related to the ABS system. Additionally, while some vehicles may produce a unique noise when braking, it’s not a definitive sign of having anti-lock brakes, as various braking systems can make distinct sounds unrelated to the presence of ABS.
