An automotive vehicle control system is equipped with a main electronic control unit for controlling devices mounted on the vehicle, and an emergency electronic control unit for backing up the main electronic control unit. Both electronic control units transmit diagnostic signals, receive the diagnostic signals from each other and diagnose them for abnormalities, whereby a fault in the main electronic control unit is diagnosed by the emergency electronic control unit and a fault in the emergency electronic control unit is diagnosed by the main electronic control unit. |
