Diagnostic Procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT OCV Inspect the OCV. (See OIL CONTROL VALVE (OCV) INSPECTION .) Is there any malfunction?	Yes	Replace the OCV, then go to Step 7. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION .)
3		No	Go to the next step.
4	VERIFY VALVE TIMING MECHANISM INSTALLATION Verify the valve timing mechanism installation for the following parts: Timing chain Camshaft sprocket lock bolt Crankshaft pulley lock bolt Is there any malfunction?	Yes	Reinstall the parts correctly, then go to Step 7. (See TIMING CHAIN REMOVAL/INSTALLATION .) (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION .)
4		No	Go to the next step.
5	INSPECT STOPPER PIN MECHANISM Remove the timing chain. (See TIMING CHAIN REMOVAL/INSTALLATION .) Inspect the stopper pin mechanism. (See VARIABLE VALVE TIMING ACTUATOR INSPECTION .) Is there any malfunction?	Yes	Replace the variable valve timing actuator, then go to Step 7. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION .)
5		No	Go to the next step.
6	INSPECT ROTOR POSITION Remove the variable valve timing actuator. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION .) Is the rotor at the maximum valve timing advanced position?	Yes	Replace the variable valve timing actuator, then go to the next step. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION .)
6		No	Variable valve timing mechanism is normal. NOTE: This DTC is detected as an intermittent concern. The intermittent concern might be removed using the cleaning mode of the variable valve timing control function. Go to the next step.
7	VERIFY DTC TROUBLESHOOTING COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE .) Switch the ignition to off. Start the engine and warm it up completely. Perform the KOER self test. (See KOEO/KOER SELF TEST .) Is the PENDING CODE for this DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION .) Go to the next step.
7		No	Go to the next step.
8	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE .)
8		No	DTC troubleshooting completed.
