Claim:
1. A terminal device which performs short-range wireless communication with an external control device and the faults of which are diagnosed by the control device, the terminal device comprising: a first power supply unit that converts electric power supplied via a plug so as to be suitable for control of the terminal device, and supplies the electric power; an antenna unit that transmits and receives short-range radio waves to and from the control device; a second power supply unit that induces electric power from the radio waves received by the antenna unit and supplies the induced electric power; a storage unit that operates after receiving the supply of electric power from the second power supply unit; a control unit that operates after receiving the supply of electric power from the first power supply unit and stores in the storage unit first information indicating whether the control unit is in an active state or an idle state, the control unit including a state updating unit which updates the first information stored in the storage unit into an active state when a state of the control unit transitions from the idle state to the active state, and updates the first information stored in the storage unit into an idle state when the state of the control unit transitions from the active state to the idle state; and an information acquiring unit that operates by using the electric power from the second power unit when the supply of electric power from the second power supply unit starts, acquires second information indicating whether electric power is supplied from the first power supply unit to the control unit, acquires the first information from the storage unit, and transmits the acquired first and second information to the control device via the antenna unit, wherein the terminal device is configured by a home appliance having a short-range wireless communication function, the control device is configured by a mobile device having a short-range communication function, and the control device diagnoses that the control unit is operating normally when a first scenario exists, wherein the first scenario is that the second information indicates a power supply state and the first information indicates the active state, that the control unit is idling normally when a second scenario exists, wherein the second scenario is that the second information indicates a non-power-supply state and the first information indicates the idle state, that the control unit has a fault and the plug is plugged in when a third scenario exists, wherein the third scenario is that the second information indicates the power-supply state and the first information indicates the idle state, and that the control unit has a fault and the plug is unplugged when a fourth scenario exists, wherein the fourth scenario is that the second information indicates the non-power-supply state and the first information indicates the active state.
