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 between 400-5,000 RPM.
* The DTCs run continuously once per crankshaft revolution after the above conditions are met for 20 crankshaft revolutions.
Conditions for Setting the DTC
