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 PURGE SOLENOID VALVE CONNECTOR CONDITION Switch the ignition to off. Disconnect the purge solenoid valve connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 10.
3		No	Go to the next step.
4	INSPECT PURGE SOLENOID VALVE POWER SUPPLY CIRCUIT FOR SHORT TO GROUND OR OPEN CIRCUIT Verify that the purge solenoid valve connector is disconnected. Switch the ignition to ON (engine off). Measure the voltage at the purge solenoid valve terminal B (wiring harness-side). Is the voltage B+ ?	Yes	Go to the next step.
4		No	Inspect the ENG BAR 15 A fuse. If the fuse is blown: Repair or replace the wiring harness for a possible short to ground. Replace the fuse. If the fuse is deteriorated: Replace the fuse. If the fuse is normal: Repair or replace the wiring harness for a possible open circuit. Go to Step 10.
5	INSPECT PURGE SOLENOID VALVE SIGNAL CIRCUIT FOR SHORT TO GROUND Verify that the purge solenoid valve connector is disconnected. Switch the ignition to off. Inspect for continuity between purge solenoid valve terminal A (wiring harness-side) and body ground. Is there continuity?	Yes	If the short to ground circuit could be detected: Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: Replace the PCM (short to ground in the PCM internal circuit). (See PCM REMOVAL/INSTALLATION .) Go to Step 10.
5		No	Go to the next step.
6	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 .)
6		No	Go to the next step.
7	INSPECT PCM CONNECTOR CONDITION Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 10.
7		No	Go to the next step.
8	INSPECT PURGE SOLENOID VALVE SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY Verify that the purge solenoid valve and PCM connectors are disconnected. Switch the ignition to ON (engine off). Measure the voltage at the purge solenoid valve terminal A (wiring harness-side). Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 10.
8		No	Go to the next step.
9	INSPECT PURGE SOLENOID VALVE SIGNAL CIRCUIT FOR OPEN CIRCUIT Verify that the purge solenoid valve and PCM connectors are disconnected. Inspect for continuity between purge solenoid valve terminal A (wiring harness-side) and PCM terminal 1BA (wiring harness-side). Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness for a possible open circuit, then 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 .) Start the engine. Perform the KOEO or 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.
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.
