An object of the present disclosure is to determine whether or not communication between ECUs after update of a software program is expected communication. A vehicular communication system includes: a storage unit which stores a first piece of information indicating data scheduled to be transmitted and received on a bus connecting a plurality of ECUs so that the ECUs can communicate with one another; an acquiring unit which acquires a second piece of information indicating data being transmitted and received on the bus when a software program of at least one of the plurality of ECUs is updated; and a determining unit which determines whether or not expected communication is being executed on the bus based on the first piece of information and the second piece of information.
