* Low brake fluid - The ABS brake light may come on when the brake fluid level is low. This is because the ABS system relies on brake fluid to function properly. Check the brake fluid reservoir and add brake fluid if necessary.
* Faulty wheel speed sensor - Wheel speed sensors monitor the speed of each wheel and send this information to the ABS controller. If a wheel speed sensor is faulty, the ABS system may not work properly and the ABS brake light may come on.
* Faulty ABS module - The ABS module is the brain of the ABS system. If the ABS module is faulty, the ABS system will not work properly and the ABS brake light may come on.
* Electrical fault - An electrical fault can also cause the ABS brake light to come on. For example, a loose wire or a blown fuse can cause the ABS system to malfunction and the ABS brake light to come on.
Solution
If the ABS brake light is on, it is important to have the vehicle diagnosed by a qualified mechanic. The mechanic will be able to identify the cause of the problem and recommend the best course of action to fix it.
