The Active M Differential is a Limited Slip Differential with electrical control to engage or disengage the differential's clutches. The DC motor is prompted by ECU based on all data gathered by sensors which is reported to activate the DSC even if the DSC is completely off. It interprets those data to provide the optimum locking force to each wheel all before a wheel breaks free.
In addition to using DSC, the Active M Differential can adapt based on pedal position, rotational speed of the wheels and yaw rate. All this happens extremely fast and precisely. This differential is able to shift power to the outside wheel in a tight turn as well as counteract the loss of traction during high speed lane changes. It can even decrease the tendency to understeer during full load cornering.
To check the functionality of Active M Differential you can turn off DSC and go to the turns and see how this system controls the stability of your car.
In order to make it more clear, here you can see the mechanical functionality of LSD and those clutches:
