On the other hand, referring to FIG. 4, when there is moisture or foreign substances in the communication terminals 113 and 123, the moisture or foreign substances may be formed as a resistance component Rf for the communication terminals 113 and 123.
The predetermined current is flowing toward the node to which the resistance element Rs is connected may flow through the resistance element Rs and the resistance component Rf.

For example, when the resistance corresponding to the communication terminals 113 and 123 is smaller than the resistance of the resistance element Rs, the controller 140 may determine that the state of the communication terminals 113 and 123 is abnormal.
Referring to FIG. 5, the switching element SW may be electrically connected to at least one of the plurality of terminals 111 to 114 included in the first connector 110 and the plurality of terminals 121 to 124 included in the second connector 120.
