DTC P2004:00 (MZR 1.5) 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" procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING .)
4	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 .) Is the PENDING CODE/DTC P2088:00 or P2089:00 also present?	Yes	Go to the applicable PENDING CODE or DTC inspection. (See DTC P2088:00 .) (See DTC P2089:00 .)
4		No	Go to the next step.
5	INSPECT VARIABLE TUMBLE SHUTTER VALVE ACTUATOR CONNECTOR CONDITION Switch the ignition to off. Disconnect the variable tumble shutter valve actuator 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 11.
5		No	Go to the next step.
6	INSPECT VARIABLE TUMBLE SHUTTER VALVE ACTUATOR Inspect the variable tumble shutter valve actuator. (See VARIABLE TUMBLE SHUTTER VALVE ACTUATOR INSPECTION .) Is there any malfunction?	Yes	Replace the variable tumble shutter valve actuator, then go to Step 11. (See VARIABLE TUMBLE SHUTTER VALVE ACTUATOR 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 11.
7		No	Go to the next step.
8	INSPECT VARIABLE TUMBLE SHUTTER VALVE POSITION SENSOR SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY Variable tumble shutter valve actuator and PCM connectors are disconnected. Switch the ignition to ON (engine off). Measure the voltage at the variable tumble shutter valve actuator 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 11.
8		No	Go to the next step.
9	INSPECT VARIABLE TUMBLE SHUTTER VALVE POSITION SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT Variable tumble shutter valve actuator and PCM connectors are disconnected. Switch the ignition to off. Inspect for continuity between variable tumble shutter valve actuator terminal A (wiring harness-side) and PCM terminal 2AL (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 Step 11.
10	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 the next step. (See VARIABLE TUMBLE SHUTTER VALVE POSITION SENSOR REMOVAL/INSTALLATION .)
10		No	Go to the next step.
11	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.
11		No	Go to the next step.
12	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 .)
12		No	DTC troubleshooting completed.
