DIAGNOSTIC PROCEDURE CHART

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 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 P2108:00 also present?	Yes	Go to the applicable DTC inspection. (See DTC P2108:00 .)
3		No	Go to the next step.
4	VERIFY CURRENT INPUT SIGNAL STATUS IS CONCERN INTERMITTENT OR CONSTANT Start the engine. Access the following PIDs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST .) ECT MAF TPREL RPM Warm-up the engine until ECT PID is above -200 °C {-392 °F} . Idle the engine for 5 s or more. CAUTION: While performing this step, always operate the vehicle in a safe and lawful manner. When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the MINI DS using the PID/DATA MONITOR AND RECORD capturing function and inspect later. Drive the vehicle under the following two PID conditions: Condition 1 TPREL: 50-87.5% RPM: above 500 RPM 4th gear (MTX), D range (ATX) Condition 2 TP REL: above 80 % RPM: below 2, 000 RPM Gear in Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST .) Is the PENDING CODE for this DTC present?	Yes	Go to the next step.
4		No	Intermittent concern exists. Go to the "INTERMITTENT CONCERN TROUBLESHOOTING" procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING .)
5	INSPECT MAF/IAT SENSOR CONNECTOR CONDITION Switch the ignition to off. Disconnect the MAF/IAT 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 8.
5		No	Go to the next step.
6	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 8.
6		No	Go to the next step.
7	INSPECT MAF SENSOR Inspect the MAF sensor. (See MASS AIR FLOW (MAF) SENSOR INSPECTION .) Is there any malfunction?	Yes	Replace the MAF/IAT sensor, then go to the next step. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION .)
7		No	Go to the next step.
8	VERIFY DTC TROUBLESHOOTING COMPLETED Make sure to connect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE .) Start the engine. Warm-up the engine until ECT PED is above -200 °C {-392 °F} . Idle the engine for 5 s or more. CAUTION: While performing this step, always operate the vehicle in a safe and lawful manner. When the M-MDS is used to observe monitor system status white driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later. Drive the vehicle under the following two PID conditions: Condition 1 TPREL: 50-87.5% RPM: above 500 RPM 4th gear (MTX), D range (ATX) Condition 2 TPREL: above 80% RPM: below 2, 000 RPM Gear in Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC 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.
8		No	Go to the next step.
9	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 .)
9		No	DTC troubleshooting completed.
