Circuit 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. The ECM 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
- A low reference circuit
If the ECM detects an open on the IC circuit of the ignition coil/module, it will set the corresponding DTC P0351-P0358.
