Abstract: A communication system includes interconnected multiple electronic controllers. At least one thereof is a multiple-circuits controller including a first electronic circuit device, a second electronic circuit device, a first power switch, a second power switch, a management frame exchange unit, and a power supply control unit. The first power switch switches between a first connected state and a first disconnected state. The second power switch switches between a second connected state and a second disconnected state. The management frame exchange unit exchanges a management frame including first switching information and second switching information. The power supply control unit switches the first power switch between the first connected state and the first disconnected state according to the first switching information and switches the second power switch between the second connected state and the second disconnected state according to the second switching information.
