VDC (Vehicle Dynamic Control) is a safety feature that can help keep you safe on the road by monitoring your car's stability and handling. It works by using sensors on your wheels to detect when the vehicle is starting to lose traction or slide, and it then makes real-time adjustments to your engine power, braking, or other systems to help you maintain control of the car. It's particularly helpful for vehicles that have trouble gripping the road, such as SUVs or electric and hybrid cars with heavy battery packs.
The system is designed to prevent accidents caused by your car sliding out of control and making sudden turns. However, it is not a substitute for good driving habits or proper care of your vehicle. Always drive at a reasonable speed, especially when on slick or uneven terrain, and be mindful of changing weather conditions.
In addition to preventing wheel slippage, VDC can also improve the performance of your vehicle by adjusting the engine's power output to match the speed and angle of the steering wheel. It can also reduce the risk of rollovers in SUVs and other top-heavy vehicles by making real-time adjustments to their speed and angle as they turn on winding roads.
Several things can cause the vehicle dynamic control light to stay on, but the most common reason is that one of the sensors on the car's wheel is faulty. If this is the case, your mechanic will replace the sensor. If the problem is more severe, he or she may need to replace the entire steering rack and ECU.
