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 10.5-18 volts.
• The engine speed is between 600-5,000 RPM.
• The DTCs run continuously once per crankshaft
revolution after the above conditions are met for 20
crankshaft revolutions.
Conditions for Setting the DTC
P2300, P2303, P2306, P2309, P2312, or P2315
The ECM detects the ignition control circuit is shorted to
ground for more than 4 seconds or a cumulative of 50
seconds.
