PURPOSE: A terminal box for diagnosing wiring is provided to enhance the operation reliability of electric-electronic apparatuses through diagnosing anomalies in the wire coupling of the electric-electronic apparatuses. CONSTITUTION: A terminal box(100) comprises an interface unit(110), a reference signal generator(120), a signal detection unit(130), and a controller(140). The interface unit performs interface with an external electronic device. The reference signal generator generates a reference signal provided to the external electronic device through the interface unit. The signal detection unit detects a reflective signal in the external electronic device for a reference signal through the interface. A controller diagnoses the wiring state of the external electronic device by comparing the reference signal with the reflective signal.
