Diagnostic Fault Information

Circuit/System Description

The ignition system on this engine uses individual ignition coils and ignition control (IC) circuits for each cylinder. Ignition voltage is supplied to

each bank of ignition coils. The engine control module (ECM) controls the ignition system operation. The ECM controls each coil using the IC

circuits. The ECM commands the IC circuit low when a spark event is requested.

The sequencing and timing are ECM controlled.

Conditions for Running the DTC

* The engine is operating.

* The ignition voltage is between 10-18 volts.

* The engine speed is less than 6,000 RPM.

* The DTCs run continuously once per crankshaft revolution after the above conditions are met.

Conditions for Setting the DTC

P0351-P0356

The ECM detects the ignition control circuit is open for greater than 4 seconds or a cumulative of 30 seconds.

P2300, P2303, P2306, P2309, P2312, or P2315

The ECM detects the ignition control circuit is shorted to ground for greater than 4 seconds or a cumulative of 30 seconds.
