Abstract

An electronic control unit includes communication units configured to be switched between a standby state, in which a communication function is restricted, and an active state, in which the restriction of the communication function is lifted. The communication units include a first communication unit (13) and a second communication unit (14) that execute first communication and second communication, respectively. The electronic control unit shifts the first communication unit (13) from the standby state to the active state in response to receiving a first activation notification through the first communication. The electronic control unit sends a second activation notification, which is a message requesting activation of the second communication unit (14) of another other electronic control unit, through the first communication and then starts the second communication with another electronic control unit.
