What Happens When Your ABS Light Comes On?

By Staff WriterLast Updated Apr 4, 2020 8:18:10 PM ET

The ABS light comes on whenever there is a fault in the anti-lock braking system in a vehicle. The fault can be a low amount of fluid in the ABS reservoir to an electrical malfunction in the wheel speed sensor, control unit or the pump, but regular braking function is unaffected. Repair involves testing or replacing control unit and pump, the wheel speed sensors or power cycling the entire system.
