This is because the VSC system relies on engine information. When the engine has problems, it can affect VSC. For example, if your engine is misfiring, this can cause both lights to come on.

Some common causes are: Faulty wheel speed sensors, Low brake fluid, Problems with the steering angle sensor.

A bad sensor can affect both systems. Low brake fluid can also impact both the braking and stability systems. Another cause might be electrical issues or problems with the vehicle's control modules.

Several factors can make both lights appear. Here’s a look at some frequent causes. This will help you understand why this happens.
