Vehicle communication device and reset guard function control program

摘要

A vehicular communication apparatus includes a connector establishing connection with an external instrument, a wireless communicator performing wireless communication when a contract enabling the wireless communication is established, and an electronic control unit. The electronic control unit is capable of operating a failsafe function executing a reset when detecting an unestablished connection between the external instrument and the connector after startup and capable of operating a reset guard function when detecting that the vehicular communication apparatus starts while the contract enabling the wireless communication is unestablished. The electronic control unit determines whether the vehicular communication apparatus is under a pre-factory-shipment state that is before being shipped from a factory, when detecting that the vehicular communication apparatus starts while the contract enabling the wireless communication is unestablished, and prohibits operation of the reset guard function while determining that the vehicular communication apparatus is under the pre-factory-shipment.
