Cars today have a multitude of sensors and warning lights that can alert the driver to a variety of potential problems. There are lights that can warn you that your car is low on oil, remind you to wear your seat belt and indicate a possible problem with your ABS system.
ABS stands for Antilock Braking System. When activated it "pumps" the brakes very quickly to allow the car to stop more effectively on slippery or dangerous roads.
The ABS light turns on when there is a problem with the car's braking system. This can mean that the ABS brakes need fluid or that it is malfunctioning. If the ABS light remains illuminated, this indicates a major problem that has disabled the ABS brakes. A major problem could be a faulty wiring harness or wheel speed sensor. If the light turns on then goes out this indicates a minor problem and the ABS brakes may still function. This is more likely to be an issue of low brake fluid or a brake pad that is wet or worn out.
Diagnosing a problem with the ABS braking system can be complicated. In general it is best to take the car to a certified mechanic. The ABS system is essential for safe driving and it should be in good working order at all times.
