Abstract
A method controls a powertrain that directs power from an engine and a transmission to all four wheels or to just front wheels or to just rear wheels. The method includes monitoring information transmitted over a communications network. The method determines whether one or more components of the powertrain are in an active condition or in an inactive condition. The one or more components of the powertrain are in the inactive condition when not connected to the transmission and not connected to the front wheels or the rear wheels. The one or more components of the powertrain are in the active condition when connected to the transmission and connected to the front wheels and the rear wheels. The method switches the one or more components of the powertrain between the inactive condition and the active condition based only on the information from the communications network and without intervention from a user.
