Method for diagnosing error of vehicle electronic component

[0034]As described herein, the present invention includes a method for diagnosing an error of a vehicle electronic component with a plurality of input / output ports comprising (a) a process of sharing unusual waveform data that cause an erroneous operation of a problematic component through a communication network; and (b) a process of obtaining the unusual waveform data and reproducing the unusual waveform data into original input waveforms to input the original input waveforms to input ports of a test component, thereby testing an erroneous operation or not of the test component.

[0035]In one embodiment, the unusual waveform data are obtained through one or more of (a-1) a process of simultaneously collecting input and output waveforms of the problematic component in operation in real time in a state where the problematic component is electrically connected to a vehicle, (a-2) a process analyzing the output waveforms to obtain information on a point in time of generation of an unusu...
