Abstract

An information sharing system () including a plurality of on-vehicle diagnosis terminals () and one or a plurality of display terminals () and sharing diagnostic information over wireless communication. The terminals () include a first determination unit S, Sand a second determination unit S, Sconfigured to determine whether or not predetermined times T, Thave passed from stored clock times C, Cat which data sets DS are acquired from the any of the other terminals (). When the predetermined times have passed, new data sets DS are acquired and the storing into an other-vehicle data storing unitB and a data storing unitA is performed. When the predetermined times have not passed, new wireless communication is established with communication units () of the terminals () capable of establishing wireless communication.
