PROBLEM TO BE SOLVED: To provide a diagnosis system capable of suppressing communication time even when transmitting segmented data to all ECUs, and completing transmission/reception of data at the same time.;SOLUTION: A diagnosis device 10 includes: start information transmission means 10a for transmitting start information (FF) showing start of data transmission; and data transmission means 10b for repeatedly transmitting data in a mode, in which all of a plurality of ECUs 21 to 23 can receive the data, by adopting the minimum value of information included in flow control information (FC) transmitted from the ECUs 21 to 23 on the basis of the flow control information. On the other hand, the ECUs 21 to 23 include: control information transmission means 21a for transmitting the flow control information when receiving the start information transmitted by the start information transmission means 10a; and data reception means 21b for receiving the data transmitted by the data transmission means.;COPYRIGHT: (C)2015,JPO&INPIT
