normal and the ignition voltage circuit fuse is open, test all components connected to the ignition voltage circuit and replace as necessary.



5. Engine running, observe the Ignition Coil 1-6 Control Circuit Low Voltage Test Status on the scan tool. Test Status should be Ok or Not



Run.



瀚慖f test status is Malfunction test for open or short to ground.



6. Engine running, observe the Ignition Coil 1-6 Control Circuit Open Test Status on the scan tool. Test Status should be Ok or Not Run.



瀚慖f test status is Malfunction test for open circuit.



7. Engine running, observe the Ignition Coil 1 6 Control Circuit High Voltage Test Status on the scan tool. Test Status should be Ok or Not



Run.



瀚慖f test status is Malfunction test for short to voltage.



8. If all circuits test normal, test or replace the T8 ignition coil.



Repair Instructions



* T8 Ignition Coil Replacement - Bank 1 (See: Powertrain Management/Ignition System/Ignition Coil/Service and Repair/Ignition Coil



Replacement - Bank 1)



* T8 Ignition Coil Replacement - Bank 2 (See: Powertrain Management/Ignition System/Ignition Coil/Service and Repair/Ignition Coil



Replacement - Bank 2)



* Control Module References (See: Testing and Inspection/Programming and Relearning) for ECM replacement, setup, and programming



Repair Verification



Note: An ignition control circuit fault condition will result in an engine misfire, and under certain driving conditions could possibly overheat the



3-way catalytic converter.



1. Install any components or connectors that have been removed or replaced during diagnosis.



2. Perform any adjustment, programming, or setup procedures that are required when a component or module is removed or replaced.



3. Clear the DTCs.



4. Turn the ignition OFF for 60 s.



5. If the repair is 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 Diagnostic Trouble Code (DTC) List - Vehicle



(See: Diagnostic Trouble Code Descriptions/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 or P0430.



P0365



DTC P0340, P0345, P0365, or P0390 (LF1)



Diagnostic Instructions



* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System



Check - Vehicle) prior to using this diagnostic procedure.



* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an



overview of the diagnostic approach.



* Diagnostic Procedure Instructions (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic Procedure



Instructions) provides an overview of each diagnostic category.
