Abstract
A first device receives an electric power from a battery via an electronic fuse. A second device is connected to the first device to transmit and receive a frame. A third device controls the operation of the electronic fuse. The first and second devices store a diagnosis mask table. The diagnosis mask table defines, for each of communication groups, one or more combinations of a device whose electric power supply via the electronic fuse is cut off, a device which enters a sleep state, and a communication frame that is not received. The third device determines an activation group based on acquired activation trigger information. The third device transmits the communication frame indicating the determined activation group to the first and second devices.
