Introduction to Brake ABS and Traction Control Systems
Brake ABS, or the Anti-lock Braking System, and traction control, are key safety features in vehicles. They work to prevent wheels from locking up during braking and to maintain grip on slippery surfaces. When the brake ABS and traction light on the dashboard illuminates, it’s a sign that there may be a fault within these systems. This guide will help you understand what these systems do and how they contribute to vehicle safety. The ABS system works by monitoring the speed of each wheel during braking.
If a wheel is about to lock, ABS reduces brake pressure to that wheel. This allows the wheel to continue rotating, helping maintain control and steerability. Traction control, on the other hand, prevents wheel spin during acceleration. It is especially helpful in wet or icy conditions. When these warning lights turn on, they indicate a potential safety hazard. It’s essential to identify and address the issue promptly. By keeping brake ABS and traction control systems in good working order, you ensure a safer driving experience. To explore the reasons behind these warnings and the steps to diagnose them, read on.
