The anti-lock braking system (ABS) is a crucial safety feature in modern vehicles, designed to prevent the wheels from locking up during hard braking, which can lead to skidding and loss of control. The ABS light on your dashboard is a warning indicator that alerts you to any issues with the system. If the anti-lock brake light stays on, it’s essential to address the problem promptly to ensure your safety on the road.
Ignoring the ABS light can lead to serious consequences, including reduced braking performance, increased stopping distance, and even accidents. Moreover, a faulty ABS system can also trigger other warning lights on your dashboard, such as the traction control light or the brake light. In this article, we’ll explore the possible causes of a stuck ABS light and provide a step-by-step guide on what to do if the anti-lock brake light stays on.
