Diagnostic Fault Information
Circuit/System Description
The ignition system on this engine uses an individual coil/module for each cylinder. The engine control module (ECM) controls the spark event for
each cylinder through the eight individual ignition control (IC) circuits. When the ECM commands the IC circuit ON, electrical current will flow
through the primary winding of the ignition coil, creating a magnetic field. When a spark event is requested, the ECM will command the IC circuit
OFF, interrupting current flow through the primary winding. The magnetic field created by the primary winding will collapse across the secondary
coil windings, producing a high voltage across the spark plug electrodes. The ECM uses information from the crankshaft position (CKP) sensor,
and the camshaft position (CMP) sensor for sequencing and timing of the spark events. Each ignition coil/module assembly has the following
