Ignition Control Module: Description and Operation: Overview



Ignition takes place with individual ignition coils placed on the spark plug concerned. The plug together with the ignition coil and CDM are used to detect combustion and any knocking.

This means that neither a camshaft sensor nor a separate knock sensor are required
For additional information, please refer to Ignition Control Module.
