Original Abstract Submitted
A communication system includes a first controller and a second controller connected to each other. The first controller receives electric power from a power source through a switch. The second controller includes a current detection unit, a management frame obtaining unit, a state comparing unit, and a diagnostic process executing unit. The current detection unit detects a consumed current value by the first controller. The management frame obtaining unit obtains a management frame including activation information of the first controller. The state comparing unit determines whether a first state based on the consumed current value and a second state based on the activation information of the first controller are inconsistent with each other. The diagnostic process executing unit performs, when the first state and the second state are inconsistent with each other, at least one of (i) storing diagnostic information and (ii) transmitting a notification of the diagnostic information.
