There are several possible causes for the ABS light to come on, including:
* A faulty ABS sensor
* A problem with the ABS control unit
* A break in the ABS wiring
* Low brake fluid level
* A problem with the brake system itself
If the ABS light is on, it is important to take your vehicle to a qualified mechanic for diagnosis and repair. Driving with a faulty ABS system can be dangerous, as it can increase your chances of losing control of your car during braking.
