Cavalier/Z24 L4-144 2.4L DOHC VIN T SFI (1996)
Ignition Control Module: Description and Operation
The Ignition Control Module (ICM) receives the Ignition Control (IC) signals from the PCM which in turn triggers the corresponding ignition coils.
Since the PCM controls spark timing and ignition control during crank and run, there is no bypass mode.
The ICM is not repairable. When an ICM is replaced, transfer the remaining components to the new module.
