Faults	Monitoring Conditions	Set Conditions	Possible Causes
Ignition Coil Control Secondary Circuit (P2302, P2305, P2308, P2311, P2314, P2317)	This diagnostic runs continuously with the engine running.	The Powertrain Control Module (PCM) detects that the Ignition System Control Module (ISCM) has identified Ignition Coil Secondary Circuit is open.	Ignition secondary circuit open/high resistance Ignition coil Ignition System Control Module (ISCM)
Ignition Coil Control Circuit Low (P2300, P2303, P2306, P2309, P2312, P2315)	This diagnostic runs continuously with the engine running.	The Powertrain Control Module (PCM) detects that the Ignition System Control Module (ISCM) has identified a short to ground in the Coil Primary Control Circuitry. The ISCM measures amperage above 24.36 amps.	Ignition coil feed circuit shorted to ground Ignition coil control circuit shorted to ground Ignition coil Ignition System Control Module (ISCM) Powertrain Control Module (PCM)
Ignition Coil Control Circuit High (P2301, P2304, P2307, P2310, P2313, P2316)	This diagnostic runs continuously with the engine running.	The Powertrain Control Module (PCM) detects that the Ignition System Control Module (ISCM) has identified a short to voltage in the Coil Control Circuitry. The ISCM measures voltage above 5.6 volts or equal to 6.1 volts.	Ignition coil feed circuit shorted to voltage Ignition coil control circuit shorted to voltage Ignition coil Ignition System Control Module (ISCM) Powertrain Control Module (PCM)
