In the electric control device, a hardware ID specific to the electronic control device and a software ID associated with a software program are set in an ROM, and rewriting of data of the ROM by a data rewriting device is permitted according to a comparison result between the hardware ID and the software ID. Here, a development software ID used at the time of development of the electronic control device and a mass production software ID used at the time of mass production are set as software IDs in the ROM. Furthermore, the hardware ID and the software ID for mass production are acquired from the ROM and are compared, and if the hardware ID and the software ID for mass production do not match each other, the software ID for development is further acquired from the ROM and the hardware ID and the software ID for development are compared.

    在电气控制装置中,电子控制装置特定的硬件ID以及与软件程序建立了对应的软件ID设定在ROM中,根据硬件ID和软件ID的对照结果,允许由数据改写装置进行的ROM的数据的改写。这里,在电子控制装置的开发时使用的开发用软件ID以及在批量生产时使用的批量生产用软件ID作为软件ID被设定在ROM中。并且,被构成为从ROM取得硬件ID以及批量生产用的软件ID,对两者进行对照,在不符合的情况下,从ROM进一步取得开发用的软件ID,对硬件ID和开发用的软件ID进行对照。
