Diagnostic procedure

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record FREEZE FRAME DATA on 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. Drive the vehicle under the following conditions. Engine coolant temperature: below 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% 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 [L5] .)
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 Is the DTC P2010, P2088 00 or P2089 00 also present?	Yes	Go to the applicable DTC inspection (See DTC P2010:00 [L5] .) (See DTC P2088:00 [L5] .) (See DTC P2089:00 [L5] .)
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 14.
5		No	Go to the next step.
6	INSPECT VARIABLE TUMBLE SHUTTER VALVE SWITCH CONNECTOR CONDITION Disconnect the variable tumble shutter valve switch 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 14
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 terminal and/or connector, then go to Step 14.
7		No	Go to the next step.
8	INSPECT SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY Switch the ignition to ON (engine off). Measure the voltage between the following terminals and body ground: PCM terminal 21 (wiring harness-side) PCM terminal 2R (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 14
8		No	Go to the next step
9	INSPECT VARIABLE TUMBLE SOLENOID VALVE Inspect the variable tumble solenoid valve (See VARIABLE TUMBLE SOLENOID VALVE INSPECTION [L5] .) Is there any malfunction?	Yes	Replace the variable tumble solenoid valve, then go to Step 14 (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L5] .)
9		No	Go to the next step
10	INSPECT VARIABLE TUMBLE SHUTTER VALVE ACTUATOR Inspect the variable tumble shutter valve actuator. (See VARIABLE TUMBLE SHUTTER VALVE ACTUATOR INSPECTION [L5] .) Is there any malfunction?	Yes	Replace the variable tumble shutter valve actuator, then go to Step 14 (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L5] .)
10		No	Go to the next step.
11	INSPECT VARIABLE TUMBLE SHUTTER VALVE SWITCH Inspect the variable tumble shutter valve switch. (See VARIABLE TUMBLE SHUTTER VALVE SWITCH INSPECTION [L5] .) Is there any malfunction?	Yes	Replace the variable tumble shutter valve switch, then go to Step 14. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L5] .)
11		No	Go to the next step
12	INSPECT SIGNAL CIRCUIT FOR OPEN CIRCUIT Switch the ignition to off Inspect for continuity between the following terminals: Variable tumble solenoid valve terminal B (wiring harness-side) and PCM terminal 21 (wiring harness-side) Variable tumble shutter valve switch terminal C (wiring harness-side) and PCM terminal 2R (wiring harness-side) Is there continuity?	Yes	Go to the next step
12		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 14
13	VERIFY CONNECTION OF VACUUM HOSE ROUTING Verify that the vacuum hoses are connected properly. (See INTAKE MANIFOLD VACUUM INSPECTION [L5] .) Are the vacuum hoses connected properly?	Yes	Go to the next step
13		No	Connect the vacuum hoses properly, then go to the next step.
14	VERIFY DTC TROUBLESHOOTING COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS Drive the vehicle under the following conditions. Engine coolant temperature: below 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% Is the PENDING CODE for this DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L5] .)
14		No	Go to the next step.
15	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [L5] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection (See DTC TABLE [L5] .)
15		No	DTC troubleshooting completed.
