in short it cuts power from the engine until the wheels are back in sync (front and back). it wont allow the rear wheels to spin, it will cut power before this happens... Also, there is DTC and DSC...
DTC wont allow for wheel spin period...
DSC wont allow the car to slide when taking turns..
when you press DTC once... you turn DTC off which will allow for wheel spin, but if the back slides DSC will cut in take away power and apply braking...
yes braking is applied to my knowledge... i have only had this vehicle but i am going based on research and reading numerous threads...
Search... is your friend...
but i hope i was able to help...
