1995 Oldsmobile Cutlass Ciera L4-2.2L VIN 4SECTION Description and Operation
Ignition Coil Assembly:
The Ignition Control Module (ICM) receives the Ignition Control (IC) signals from the Powertrain Control Module (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, the remaining components must be transferred to the new module.
