Abstract: An ECU outputs an ignition signal Si to an ignition apparatus through an ignition communication line, and outputs a discharge waveform control signal Sc with a logic H through a waveform control communication line. The ignition apparatus performs the closing operation of an ignition switching element, in a period during which the ignition signal Si is input. In an input period of the discharge waveform control signal Sc after stopping the input of the ignition signal Si, the ignition apparatus controls the electric current to flow through a primary coil, by the opening-closing operation of a control switching element. When the voltage of the waveform control communication line Lc is the logic H in an output stop period of the discharge waveform control signal Sc, the ECU determines that the waveform control communication line is abnormal, and executes a fail-safe process.
