Kind Code:
A1
Abstract:
An onboard communications device that: is communicably connected to onboard ECUs mounted in a vehicle; obtains configuration information sent from each of the onboard ECUs; and comprises a control unit that controls communications with an external authentication device connected from outside the vehicle, when an onboard ECU is replaced or added. The control unit tries to communicate with the external authentication device when the previously obtained configuration information differs from the configuration information obtained on this occasion. If communications with the external authentication device was unable to occur normally, the control device determines that an onboard ECU has been illegally replaced or added.
