Why does my abs light come on when I brake?

The ABS (Anti-lock Braking System) light may illuminate when you brake due to a malfunction or issue within the ABS system. This could be caused by a faulty wheel speed sensor, low brake fluid levels, or a problem with the ABS module itself. It's essential to have your vehicle checked by a professional mechanic to diagnose and address the underlying issue, as the ABS system is crucial for safe braking performance. Ignoring the light could lead to compromised braking efficiency.
