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	VERIFY RELATED PENDING CODE AND/OR DTC Switch the ignition to off, then to ON (engine off). Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST .) Are any other PENDING CODEs and/or DTCs present?	Yes	Go to the applicable PENDING CODE or DTC inspection. (See DTC TABLE .)
3		No	Go to the next step.
4	INSPECT FUEL TANK VACUUM Switch the ignition to off. Verify kinks or bends in the fuel vapor hoses and tubes. Visually inspect the charcoal canister inlet port, CV solenoid valve, EVAP dust separator or outlet hose has contamination or foreign material. Is a concern evident?	Yes	Remove any contamination or foreign material around fuel vapor hoses and tubes. Repair the hoses, tubes or components if necessary, then go to Step 10.
4		No	Go to the next step.
5	PERFORM EVAP SYSTEM LEAK INSPECTION Connect the leak tester to the fuel filler pipe. Access the EVAPCV PID of simulation item using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST .) Close the CV solenoid valve using the EVAPCV PID. Pressurize the EVAP system to 3.48 kPa {26.1 mmHg, 1.03 inHg} . Does the pressure reach 3.48 kPa {26.1 mmHg, 1.03 inHg} ?	Yes	Go to the next step.
5		No	Replace the CV solenoid valve, then go to Step 10. (See CANISTER VENT (CV) SOLENOID VALVE REMOVAL/INSTALLATION .)
6	INSPECT CV SOLENOID VALVE Access the EVAPCV PID of simulation item using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST .) Open the CV solenoid valve using the EVAPCV PID. Does the pressure drop immediately?	Yes	Go to the next step.
6		No	Replace the CV solenoid valve, then go to Step 10. (See CANISTER VENT (CV) SOLENOID VALVE REMOVAL/INSTALLATION .)
7	INSPECT PURGE SOLENOID VALVE Inspect the purge solenoid valve. (See PURGE SOLENOID VALVE INSPECTION .) Is there any malfunction?	Yes	Replace the purge solenoid valve, then go to Step 10. (See PURGE SOLENOID VALVE REMOVAL/INSTALLATION .)
7		No	Go to the next step.
8	INSPECT FUEL TANK PRESSURE SENSOR Switch the ignition to off. Disconnect the charcoal canister outlet tube at the charcoal canister. Switch the ignition to ON (engine off). Select the Diagnostic Data Link using the M-MDS. Select the PCM. Access the FTP PID and record the reading. (See ON-BOARD DIAGNOSTIC TEST .) Is the reading between 2.4-2.8 V ?	Yes	Go to the next step.
8		No	Replace the evaporative hose component, then go to Step 10. (See FUEL TANK REMOVAL/INSTALLATION .)
9	PERFORM EVAP SYSTEM LEAK INSPECTION Switch the ignition to off. Reconnect all disconnected connectors and hoses. Perform the Evaporative Emission (EVAP) System Leak Inspection. (See ENGINE CONTROL SYSTEM OPERATION INSPECTION .) Is there any malfunction?	Yes	Leakage still exists. Locate the leak point and repair. Repeat this step.
9		No	Go to the next step.
10	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 .) Perform the Drive Mode 06 (EVAP System Repair Verification Drive Mode). (See OBD-II DRIVE MODE .) 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.
10		No	Go to the next step.
11	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 .)
11		No	DTC troubleshooting completed.
