What Is the DSC Button On BMW?

The term DSC is a shortened name for Dynamic Stability Control. It is a suspension control system. This control system is way beyond ABS’s components, Automatic Stability Control, Cornering Brake Control, or the CBC. 

The DSC or Dynamic Stability Control is known to be the nucleus of the chassis control systems in BMW cars. There are plenty of people who are still unaware of this DSC and what they do. 

Some people take it for granted, not giving time to knowing what it does. As a driver of a BMW car, have the time to know about DSC and how it contributes to your car’s performance.

How Does BMW DSC Work?

A DSC or Dynamic Stability Control function monitors the individual wheel speed together with the yaw rate. Through the various sensors, the lateral and longitudinal acceleration is also monitored. 

The DSC or Dynamic Stability Control is the safety net version of the BMW for their cars. Every time you start your BMW, this DSC or Dynamic Stability Control will automatically be activated. 

The DSC or Dynamic Stability Control can also get information about the speed of the vehicle. It is not only limited to the vehicle speed; the Dynamic Stability Control can also get information about the position of the throttle, the steering angle sensor, the force or position of the brake pedal, and the speed of the engine. 

All these data will be given to the DSC or Dynamic Stability Control. What is good about the Dynamic Stability Control is that it creates an ideal driving condition. It will also base it on the current condition of your vehicle. 

When you drive and steer sharply, the ideal driving condition will notice the movement as something deviated from the ideal condition. As a return, the Dynamic Stability Control will do necessary changes that will converge your driving to the ideal driving condition calculated by the Dynamic Stability Control.

On the other hand, if you steer shortly, it is still a deviation of the ideal driving condition; the Dynamic Stability Control will bridge the gap. Every time this happens, the Dynamic Stability Control will do its job and will make adjustments internally. These adjustments are limited to cutting the fuel, applying brakes, and any other methods.

Should DSC Be On or Off?

As mentioned, the Dynamic Stability Control will automatically turn if once you start your engine. This is a part of safety features. However, some people always ask if the Dynamic Stability Control must be turned on or turned off.  

The answer depends on the driver. You can always turn off your Dynamic Stability Control, and you always turn them back on. Some BMW owners advised that you turn off your Dynamic Stability Control when you are on a wet road or snowy weather. 

The Dynamic Stability Control will help you maintain your traction. If you turn your Dynamic Stability control off, you will lose traction when you maneuver in accidental situations. This might also make you lose control of your car. 

Some people treat Dynamic Stability Control as an airbag. They always turn it on for safety and protection. 

However, some people still chose to turn it off because they thought their car was not going any faster. If you want to be on the safe side, it is better to leave the Dynamic Stability Control on all the time.
