Abstract
A communication circuit, a communication system, and a self-diagnosis method of the communication circuit, which facilitate specifying a failed part which causes a communication failure when a communication failure occurs in a communication system, are provided. A serial signal for self-diagnosis is supplied to a first conversion unit, a pulse signal for self-diagnosis corresponding to the serial signal for self-diagnosis output from the first conversion unit is input to a second conversion unit instead of a pulse signal received by a pulse signal reception unit, and the serial signal corresponding to the pulse signal for self-diagnosis output from the second conversion unit is transmitted to the outside via a serial signal transmission unit.
