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
circuits:
* Ignition voltage
* Ground
* Ignition control (IC)
* Low reference
If the ECM detects that the IC circuit has an incorrect voltage level, DTC P0351-P0358 will set.
Conditions for Running the DTC
* The ignition is ON.
* DTC P0351-P0358 runs continuously when the above condition is met.
Conditions for Setting the DTC
The ECM detects one of the following failures on the IC circuit:
* An open
* A short to ground
* A short to voltage
Action Taken When the DTC Sets
DTCs P0351-P0358 are Type B DTCs.
Conditions for Clearing the DTC
DTCs P0351-P0358 are Type B DTCs.
