Summary:PROBLEM TO BE SOLVED: To shorten time required for transferring write data in an electronic control unit for an automobile.SOLUTION: When data to be written in a ROM 110 on an ECU (an Electronic Control Unit) 100 is transferred from a writing tool 200 to the ECU 100, the ECU 100 performs communication by using not only a communication buffer used in order for the ECU 100 to communicate with the writing tool 200 in an on-board state but also a communication buffer used to communicate with a device other than the writing tool 200 in the on-board state out of communication buffers of a communication buffer region 141. 【課題】自動車用電子制御装置において、書込みデータの転送に要する時間を短縮する。【解決手段】書込みツール２００からＥＣＵ１００に対し、ＥＣＵ１００上のＲＯＭ１１０に書込むためのデータを転送するとき、ＥＣＵ１００は、通信バッファ領域１４１の通信バッファのうち、車載状態においてＥＣＵ１００が書込みツール２００と通信するために使用する通信バッファに加えて、車載状態において書込みツール２００以外の装置と通信するために使用する通信バッファを使用して通信を行う。【選択図】図２
