<p>PROBLEM TO BE SOLVED: To provide a control device for an ignition circuit capable of improving the reliability of the device without requiring a additional hardware cost and a wiring cost. SOLUTION: A plus output stage and a minus output stage of a substrate that are relatively independent are connected to each ignition circuit. Means for diagnosing the ignition circuit are assigned to the plus output stage and the minus output stage. The ignition circuit is provided with a means for controlling the plus output stage and the minus output stage.</p> |
