Ignition Control Module: Description and Operation

IGNITION COIL AND IC MODULE

The ignition coil provides the necessary secondary energy to produce a strong enough spark at the plugs. The coil is triggered by the IC module which in turn is commanded by the PCM. There is no back-up or by-pass function in the IC module.
