If you’ve got an ABS-equipped car, you have an ABS warning light. If it comes on, pay close attention and get it checked as soon as possible.
It means the ABS computer has diagnosed that something is amiss in the system. It could be something as simple as dirt in one of the sensors or something as costly as an entire ABS unit replacement. It’s important to note that this light normally comes on when you start the car and then switches off a few seconds later. If it blinks, throbs, flashes or in any other way draws your attention to itself, take note. Compared to a steady light, a blinking ABS light normally indicates something more serious. In some cases, it could be a warning that you have no brakes at all.
