PURPOSE: An error managing method transmitting a processing instruction for a driving error of a driving device, a system thereof, and a error display device thereof are provided to conveniently supply the processing instruction for the driving error occurring in the driving device by simply scanning an error code about the driving error. CONSTITUTION: An error display device(10) is installed in a driving device to detect error information about a driving error of the driving device. The error display device displays an error code encoded from the error information. A portable terminal(30) scans the error code and decodes the same with the error information. A server(50) receives the error information from the portable terminal, generates a processing instruction for the driving error based on the error information, and transmits the processing instruction to the portable terminal. The error display device includes an error information detecting unit and an error display device control unit.
