Testing your vehicle's ABS involves a straightforward procedure. Initially, you can start by looking for the ABS light on your dashboard when you start the car. This light should briefly illuminate as part of the system's self-check process and then turn off. If the light stays on, it indicates a potential issue with the ABS. For a more practical test, find a safe and controlled environment, like an empty parking lot, and perform a controlled brake at a moderate speed. You should feel a pulsing or vibrating sensation in the brake pedal, indicating the ABS is engaging.
