Abstract
A main body ECU as a slave node includes a switch. The switch is under OFF state when a prohibition signal is outputted from a verification ECU as a master node and under ON state when the prohibition signal is not outputted. The switch is inserted in a reception path between a receive port of a microcomputer of the main body ECU and a receiver of a transceiver that is connected with a communication bus. When the switch is under OFF state, a reception signal outputted by the transceiver is not inputted into the microcomputer of the main body ECU. Therefore, the microcomputer is not activated even if an activation frame is transmitted to the communication bus; this enables the main body ECU to maintain a sleep mode.
