PROBLEM TO BE SOLVED: To prevent a situation in which a program region is destructed because of failure of reprography by a dealer, and even if re-reprography is tried, a high-order electronic control device determines that a low-order electronic control device is abnormal and cuts off a power supply relay, relating to a reprographic technology with the low-order electronic control device by a mutual monitoring module in an electronic control device for a vehicle.SOLUTION: Once a monitoring device detects abnormality of ATCU and turns off the ATCU relay, being a fail safe state, however if reprography is required once more, the monitoring device receives reprography request from a reprography device to turn on the ATCU relay, thus, shifting to a reprography mode is made independent of the state of the ATCU.SELECTED DRAWING: Figure 4

    【課題】車両用電子制御装置における相互監視モジュールによる下位電子制御装置のリプロ手法に関し、ディーラーでのリプロ失敗が原因でプログラム領域が破壊され、再リプロを試みようとしても上位電子制御装置が下位電子制御装置を異常と判断し電源リレーを遮断してしまうことを防止することを目的とする。【解決手段】監視装置がATCUの異常を検知し、一旦フェールセーフ状態、即ちATCUリレーをオフ制御するが、再度リプロが必要な場合には、監視装置がリプロ装置からのリプロ要求を受信し、ATCUリレーをオン制御できるため、ATCUの状態に依存せずリプロモードに移行させることができる。【選択図】図4
