号を、クランク角センサからのクランク角信号に
基づいて順次独立して出力する制御手段を有する
内燃機関の点火装置において、気筒が点火したと
きに発せられる点火信号を各点火コイルから検出
する点火信号検出手段と、前記各気筒の点火信号
を合成し１つの合成信号に変換する信号変換手段
と、該合成信号より前記点火装置の異常判定を行
う異常判定手段とを、備えたことを特徴とする内
燃機関用点火装置の自己診断装置。 In an ignition system for an internal combustion engine that has a control means that sequentially and independently outputs an ignition control signal for each ignition coil provided for each cylinder based on a crank angle signal from a crank angle sensor, the signal is emitted when a cylinder is ignited. ignition signal detection means for detecting an ignition signal from each ignition coil; signal conversion means for combining the ignition signals of the respective cylinders and converting them into one composite signal; and abnormality determination for determining an abnormality of the ignition device based on the composite signal. A self-diagnosis device for an ignition device for an internal combustion engine, comprising: means.
