Abstract
The present invention provides an electronic controller and the like capable of identifying the order of communication apparatuses connected to a bus while minimizing manufacturing cost. In the present invention, bus wiringhas one end connected to a portand the other end connected to a port. A plurality of lower ECUstoare connected to the bus wiring. A current sensor CS measures current Isflowing through the portand current Isflowing through the portby applying current to the bus wiringfrom each of the plurality of lower ECUsto. The higher controlleridentifies the order of the plurality of lower ECUstoon the bus wiringon the basis of the current Isand the current Iswhich are measured for each of the plurality of lower ECUsto
