Yup, DirtyTool is a smart guy. The engine intervention function of DSC can be disabled by simply pressing the button on the console and reactivated by pressing again. But this will only affect the engine intervention function.
If you want to deactivate DSC's brake modulation function, press and hold the DSC button until the light stays on. This will not fully disable the brake modulation function -- it will only roll its operational parameters very far forward.
Depending on your year, you may have to turn the car off and turn back on, to restore original DSC function...if later, simply pushing the DSC button will restore DSC back to normal parameters.
