ABSTRACT:
When it is detected that the state of an electrical component connected to a communication node has not changed in the OFF state of an ignition key switch, it is determined that a vehicle equipped with the multiplex transmission apparatus is in a parking state, and the communication node is forcibly shifted to a sleep state, thereby preventing consumption of battery power due to a dark current supplied to the communication node in the sleep state.
