ABSTRACT:
An electronic control unit (ECU) for a vehicle is disclosed. The subject ECU stores: vehicle ID; and first cross-check information different from the vehicle ID. The subject ECU acquires second cross-check information different from the vehicle ID. The second cross-check information is stored in an external ECU that is mounted in a same vehicle as the subject ECU is mounted. The subject ECU determines whether the first cross-check information matches the second cross-check information.
