Ignition Control Module: Description and Operation
PURPOSE/OPERATION
Controls ignition discharge by interrupting the ignition coil primary current ground. The igniter is a switching device used to interrupt the ignition
coil ground connection and induce high voltage from the coil secondary windings. A signal from the ECM controls igniter switching, enabling the
ECM to regulate ignition timing based engine operating condition information received from various sensors.
