In an electric control device, a hardware ID unique to an electronic control device and a software ID associated with a software program are set in a ROM, and rewriting of data of the ROM by a data rewriting device is permitted depending on a result of collating the hardware ID with the software ID. Here, a software ID for development used during development of the electronic control device and a software ID for mass-production used during mass-production are set as the software ID in the ROM. Then, the hardware ID and the software ID for mass-production are acquired from the ROM, the IDs are collated, and if there is no conformity between the IDs, the software ID for development is further acquired from the ROM to collate the hardware ID with the software ID for development.
