ELECTRONIC IGNITION (EI) SYSTEM DIAGNOSIS
CIRCUIT DESCRIPTION
The ignition system uses individual ignition coil/module assemblies for each cylinder. The powertrain control module (PCM) controls the individual coils by transmitting timing pulses on the ignition control (IC) circuit of each ignition coil/module to enable a spark event. The PCM monitors each IC circuit for improper voltage levels. Each ignition coil/module has the following circuits:
- An ignition voltage circuit
- A ground
- An IC circuit
