Abstract
An electronic control unit includes a relay device that is connected via a first network with a different relay device included in a different electronic control unit to relay a frame via the first network. It is determined whether a reception interruption has occurred. The reception interruption signifies that at least one predetermined frame scheduled to be transmitted from the different relay device is not received within a predetermined time via the first network. In response to the reception interruption being determined to have occurred, it is determined whether an abnormality has occurred in the first network based on at least one of (i) a presence or absence of reception of a state data representing a state of the different electronic control unit from the different electronic control unit via a second network within a fixed time, and (ii) a content of the state data.
