Circuit/System Description
|
The ignition system uses individual ignition coil/module assemblies for each cylinder. The engine control module (ECM) controls the individual coils by transmitting timing pulses on the ignition control (IC) circuit of each ignition coil/module to enable a spark event. When the engine is running the ECM monitors each IC circuit for improper voltage levels. Each ignition coil/module has the following circuits:
Conditions for Running the DTCs
|
•
|
The engine speed is less than 6,000 RPM.
|
•
|
The ignition 1 voltage signal is between 9-18 V.
|
•
|
DTCs P2300, P2301, P2303, P2304, P2306, P2307, P2309, P2310 run continuously when the above conditions are met.
|
Conditions for Setting the DTCs
|
•
|
The ECM detects a short to ground on the circuit or the ignition coil/module for greater than 4 seconds continuously or 50 seconds cumulative.
OR
|
•
|
The ECM detects a short to voltage on the circuit or the ignition coil/module for greater than 4 seconds continuously or 50 seconds cumulative.
|
Action Taken When the DTC Sets
|
DTCs P2300, P2301, P2303, P2304, P2306, P2307, P2309, P2310 are Type B DTCs.
Conditions for Clearing the MIL/DTC
|
DTCs P2300, P2301, P2303, P2304, P2306, P2307, P2309, P2310 are Type B DTCs.

Circuit/System Verification
|
1.
|
Start and run the engine.
|
2.
|
Observe the scan tool Misfire Current Cylinder parameters. The counters should not be incrementing.
|
3.
|
Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
|
1.
|
Turn ON the ignition, with the engine OFF.
|
2.
|
Test the affected ignition control circuit terminal C for a short to ground or for a short to voltage.
|
3.
|
If a fault is found, repair the circuit as needed.
|
4.
|
Ignition OFF, exchange the affected T8 ignition coil/module with the T8 ignition/coil module of a good cylinder.
|
5.
|
Start the engine and observe the scan tool.
|
6.
|
If the DTC or the misfire transfers with the suspect ignition/coil module, replace as needed.
|
7.
|
If the DTC or the misfire does not transfer with the suspect T8 ignition/coil module, replace the K20 ECM.
|
If the customer concern was a flashing MIL, then perform the following procedure:
1.
|
Install any components that have been removed or replaced during diagnosis.
|
2.
|
Perform any adjustments, programming or setup procedures that are required when a component is removed or replaced.
|
4.
|
Turn OFF the ignition for 60 seconds.
|
5.
|
If the repair was related to a DTC, duplicate the Conditions for Running the DTC and use the Freeze Frame/Failure Records, if applicable, in order to verify the DTC does not reset. If the DTC resets or another DTC is present, refer to the
Diagnostic Trouble Code (DTC) List - Vehicle
and perform the appropriate diagnostic procedure.
|
6.
|
To verify that the performance of the catalytic converter has not been affected by the condition that set this DTC, perform the Repair Verification for DTC P0420. Refer to
DTC P0420
