摘要: An electronic control apparatus for a vehicle having an engine control unit 114 controlling an electronically-controlled throttle of an engine and a valve control unit 141 controlling a variable lift mechanism 112 that varies a lift amount of an intake valve are provided. Information of a target lift amount and an actual lift amount is transmitted/received between these control units. Each of the control units diagnoses a state of data transmission from the other control unit, transmits the diagnosis result to the other control unit and, when the diagnosis result of itself and/or the diagnosis result of the other control unit shows an abnormal state, moves to the mode of a fail-safe operation.
