Abstract
An electronic control device includes a nonvolatile memory having allocated two storage areas that are exclusively switchable between an active state and an inactive state, the storage area in the active state being used to store a control program to be executed, and the storage area in the inactive state being used as a reserved area for updating the control program. In the electronic control device, when the control program is not updated, arbitrary data is written in the storage area in the inactive state.
