Circuit/System Description
WARNING: This page is about a different variant/trim than selected.
The ignition system uses individual ignition coil/module assemblies for each cylinder. The engine control module (ECM) controls the individual coils by transmitting timing pulses on the ignition control (IC) circuit of each ignition coil/module to enable a spark event. Each ignition coil/module has the following circuits:
- An ignition voltage circuit
- A ground circuit
- An IC control circuit
- A low reference circuit
