PROBLEM TO BE SOLVED: To shorten the time up to an engine stop by driving the engine when an engine drive allowance signal is inputted within a set time from the start of an engine start and outputting a signal disobeyed to a communication protocol to an engine control part when the discrimination code from a coil unit is NO. SOLUTION: An engine control part 10 allows a fuel by a fuel injection valve 26 and an ignition by an ignition coil 28, when an engine drive allowance signal is inputted from a coil unit 6 to an immobilizer control part 8 within a set communication time from the start of an engine start by the rotation to the start position of an ignition key 4 and the drive of the engine is continued. A prohibition signal output part 34 is installed in the immobilizer control part 8 and a signal disobeyed to a communication protocol for the engine control part 10 is outputted as an engine drive prohibition signal, when a discrimination code inputted from the coil unit 6 to the immobilizer control part 8 is NO. |
