A communication system includes a network formed by a plurality of control units, each operated in a high power consumption mode and a low power consumption mode. A selected one or more of the control units act solely or in cooperation with each other to implement a specific function. Each of the selected one or more of the control units related to the specific function is set in the high power consumption mode. Each of the non-selected control units unrelated to the specific function is set in the low power consumption mode.
