Electronic Ignition (EI) System Diagnosis
ELECTRONIC IGNITION (EI) SYSTEM DIAGNOSIS
CIRCUIT DESCRIPTION
There are 3 dual-tower ignition coils that are part of the ignition control module (ICM). The ICM contains coil driver circuits that command the coils to operate. The ICM has the following circuits:
- An ignition voltage circuit
- A ground
- An ignition control (IC) 1 control circuit for the 1-4 ignition coil
- An IC 2 control circuit for the 2-5 ignition coil
- An IC 3 control circuit for the 3-6 ignition coil
- A low reference circuit
The powertrain control module (PCM) controls each dual-tower ignition coil by transmitting timing pulses on the ignition coil control circuit to the ICM for the proper coil to enable a spark event.
