Control system of a full drive

When the switch of a full drive is included by switching of the lever of a gear change, the electronic block of management (ESM/RSM) (at models with engines G16 and J20) or puts the controller of a full drive in action (activates) the air pump. Then positive pressure arrives from the air pump in the actuator established on the case of differential, and forces муфту axis blocking to contact to the free plug of an axis in the differential case that creates a mode of a full drive. Only at movement in a mode of a full drive forward axes join the differential case, and are released, when the drive on two wheels (or when the gear change lever is switched in position N) is used, reducing thereby capacity loss.
