Circuit/System Description
WARNING: This page is about a different variant/trim than selected.
This ignition system uses individual ignition module/coil assemblies for each cylinder. The engine control module (ECM) controls the spark events by transmitting the timing pulses on the ignition control (IC) circuits to the individual ignition module/coil assemblies in firing order sequence. Each ignition module/coil has the following circuits:
- An ignition 1 voltage circuit
- A ground circuit
- An IC circuit
- A low reference circuit
