What is DSC

DSC, short for Dynamic Stability Control is a suspension control system which goes beyond the single components of ABS, Cornering Brake Control (CBC) and Automatic Stability Control. It works by monitoring each wheel speed individually along with yaw rate and longitudinal and lateral acceleration through various sensor.

The DSC module also receives information from vehicle speed and engine speed, throttle position, brake pedal position/force and the steering angle sensor. All of this information collected is fed to the DSC control module and process.

The DSC computer constantly calculates an ideal driving condition that is compared with the current status. If the vehicle oversteers or understeers, the calculated ideal deviates from the measured status, and DSC will intervene within a few milliseconds via the engine management system by either applying brakes at different wheels, cutting fuel, and a few other methods that are too detailed for this short presentation

The DSC system can be deactivated via the center console button.

As I mentioned at the beginning of this article, DSC stands for Dynamic Stability Control and DTC is Dynamic Traction Control. If the DSC button in your dashboard is pressed once, the DSC system will be deactivated. To deactivate DTC, the button needs to be held for a few seconds longer.

DSC is a great safety feature in any car and it has and will save many cars and their passengers.
