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	CLASSIFY INTERMITTENT CONCERN OR CONTINUOUS CONCERN Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE .) Drive the vehicle under the following conditions: Engine coolant temperature: above 60 °C {140 °F} Engine speed: below 3,750 rpm Throttle opening angle is below as followings: Engine speed-below 1,500 rpm : above 35 % Engine speed-between 1,500-2,500 rpm : between 25-35 % Engine speed-above 2,500 rpm : below 25 % Perform the KOER self test. (See KOEO/KOER SELF TEST .) Is the PENDING CODE for this DTC present?	Yes	Go to the next step.
3		No	Intermittent concern exists. Perform the "INTERMITTENT CONCERN TROUBLESHOOTING". (See INTERMITTENT CONCERN TROUBLESHOOTING .)
4	VERIFY RELATED PENDING AND STORED DTC Switch the ignition to off, then to ON (engine off). Verify pending and stored DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST .) Is the DTC P2009:00 also present?	Yes	Go to the applicable DTC inspection. (See DTC P2009:00 .)
4		No	Go to the next step.
5	INSPECT VARIABLE TUMBLE SOLENOID VALVE CONNECTOR CONDITION Switch the ignition to off. Disconnect the variable tumble solenoid valve connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the terminal and/or connector, then go to Step 12.
5		No	Go to the next step.
6	INSPECT VARIABLE TUMBLE SOLENOID VALVE Inspect the variable tumble solenoid valve. (See VARIABLE TUMBLE SOLENOID VALVE INSPECTION .) Is there any malfunction?	Yes	Replace the variable tumble solenoid valve, then go to Step 12. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
6		No	Go to the next step.
7	INSPECT VARIABLE TUMBLE SHUTTER VALVE POSITION SENSOR CONNECTOR CONDITION Disconnect the variable tumble shutter valve position sensor connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the terminal and/or connector, then go to Step 12.
7		No	Go to the next step.
8	INSPECT VARIABLE TUMBLE SHUTTER VALVE POSITION SENSOR Inspect the variable tumble shutter valve position sensor. (See VARIABLE TUMBLE SHUTTER VALVE POSITION SENSOR INSPECTION .) Is there any malfunction?	Yes	Replace the variable tumble shutter valve position sensor, then go to Step 12. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
8		No	Go to the next step.
9	INSPECT VARIABLE TUMBLE SHUTTER VALVE ACTUATOR Perform the Variable Tumble Control Operation Inspection. (See ENGINE CONTROL SYSTEM OPERATION INSPECTION .) Is the variable tumble shutter valve actuator normal?	Yes	Go to the next step.
9		No	Repair or replace the malfunctioning part according to the inspection results, then go to Step 12.
10	INSPECT VARIABLE TUMBLE SOLENOID VALVE AND VARIABLE TUMBLE SHUTTER VALVE POSITION SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND Variable tumble solenoid valve and variable tumble shutter valve position sensor connectors are disconnected. Inspect for continuity between the following terminals and body ground: Variable tumble shutter valve position sensor terminal C (wiring harness-side) Variable tumble solenoid valve terminal B (wiring harness-side) 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 PCM internal circuit). (See PCM REMOVAL/INSTALLATION .) Go to Step 12.
10		No	Go to the next step.
11	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 terminal and/or connector, then go to the next step.
11		No	Go to the next step.
12	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 .) Drive the vehicle under the following conditions: Engine coolant temperature: above 60 °C {140 °F} Engine speed: below 3,750 rpm Throttle opening angle is below as followings: Engine speed-below 1,500 rpm : above 35 % Engine speed-between 1,500-2,500 rpm : between 25-35 % Engine speed-above 2,500 rpm : below 25 % 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.
12		No	Go to the next step.
13	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 .)
13		No	DTC troubleshooting completed.
