Diagnostic Procedure

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION Note •  Recording can be facilitated using the screen capture function of the PC. •  Record the freeze frame data/snap shot data.	―	Go to the next step.
2	VERIFY OTHER RELATED DTCs •  Switch the ignition OFF, and then switch it ON (engine off). •  Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) •  Has any DTC other than P2106:00 been stored?	Yes	If DTC P1142:00 or P004A:00 is stored: •  Go to the next step. If DTC other than P1142:00 or P004A:00 is stored: •  Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)])
		No	Go to the next step.
3	VERIFY AVERAGE DISTANCE INTERVAL OF diesel particulate filter REGENERATION TO DETERMINE IF MALFUNCTION IS CAUSED BY INJECTOR SYSTEM Note •  If the diesel particulate filter has been replaced and the diesel particulate filter data has been reset in the past, or the PCM has been replaced, use the traveled distance from the time of the related servicing until the time the vehicle was brought in. •  Perform the following procedure: 1.  Display the following PID diesel particulate filter_REG_CNT using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) 2.  Divide the current traveled distance (odometer display) by the value of PID diesel particulate filter_REG_CNT and verify the average value of the diesel particulate filter regeneration interval. •  Average value of the diesel particulate filter regeneration interval equals traveled distance divided by value of PID diesel particulate filter_REG_CNT •  Is the average value of the diesel particulate filter regeneration interval 140 km or more?	Yes	Go to the next step.
		No	Replace the fuel injector, then go to Step 12. (See FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
4	DETERMINE IF MALFUNCTION IS CAUSED BY TURBOCHARGER •  Switch the ignition OFF. •  Switch the ignition ON (engine on). •  Display PID VGTURB_ACT and simulation item VGTURB_DSD using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) •  Operate the turbocharger with variable geometry using the simulation item VGTURB_DSD. •  Does PID VGTURB_ACT change according to the simulation operation.	Yes	Go to the next step.
		No	Replace the turbocharger, then go to Step 14. (See TURBOCHARGER REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
5	VERIFY IF METAL FRAGMENTS PENETRATED ENGINE OIL •  Drain the engine oil. (See ENGINE OIL REPLACEMENT [SKYACTIV-D 2.2]) •  Are there metal fragments in the drained engine oil?	Yes	Replace or overhaul the engine as a partial engine. (See ENGINE REMOVAL/INSTALLATION [SKYACTIV-D 2.2]) Refer to the engine workshop manual. Go to Step 12.
		No	Go to the next step.
6	Remove any engine oil in the piston cavity. •  Perform the following procedure: 1.  Remove the glow plug. (See GLOW PLUG REMOVAL/INSTALLATION [SKYACTIV-D 2.2]) 2.  Hold cloth over the glow plug installation hole. 3.  Crank the engine and remove the engine oil from the glow plug installation hole.	―	Go to the next step.
7	INSPECT ENGINE COMPRESSION PRESSURE •  Inspect the engine compression pressure. (See COMPRESSION INSPECTION [SKYACTIV-D 2.2]) •  Is the engine compression pressure normal?	Yes	Go to the next step.
		No	Repair or replace the malfunctioning location, then go to Step 12.
8	VERIFY CHARGE AIR COOLER CONDITION •  Verify the charge air cooler condition. (See CHARGE AIR COOLER REMOVAL/INSTALLATION [SKYACTIV-D 2.2]) •  Is there any engine oil in the charge air cooler inlet pipe or the charge air cooler outlet pipe?	Yes	Remove any engine oil in the charge air cooler with a cloth, then go to Step 12.
		No	Go to the next step.
9	VERIFY CONDITION OF BOTTOM SURFACE IN INTAKE MANIFOLD •  Verify the condition of the bottom surface in the intake manifold. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2]) •  Is there any engine oil on the bottom in the intake manifold?	Yes	Remove any engine oil on the bottom in the intake manifold with a cloth, then go to the next step.
		No	Go to the next step.
10	INSPECT MAP SENSOR •  Reconnect all the disconnected connectors. •  Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [SKYACTIV-D 2.2]) •  Is the MAP sensor normal?	Yes	Go to the next step.
		No	Replace the MAP sensor, then go to the next step. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
11	INSPECT EXHAUST GAS PRESSURE SENSOR NO.1 •  Reconnect all the disconnected connectors. •  Inspect exhaust gas pressure sensor No.1. (See EXHAUST GAS PRESSURE SENSOR INSPECTION [SKYACTIV-D 2.2]) •  Is exhaust gas pressure sensor No.1 normal?	Yes	Go to the next step.
		No	Replace exhaust gas pressure sensor No.1, then go to the next step. (See EXHAUST GAS PRESSURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
12	PERFORM COMPULSORY diesel particulate filter REGENERATION AND BURN OUT ENGINE OIL IN diesel particulate filter •  Perform compulsory diesel particulate filter regeneration. (See COMPULSORY DIESEL PARTICULATE FILTER REGENERATION [SKYACTIV-D 2.2]) Note •  When a DTC is stored, compulsory diesel particulate filter regeneration may be restricted by the PCM control. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) ―  When a high quantity of soot has accumulated in the diesel particulate filter and the PCM has stored DTC P242F:00, compulsory diesel particulate filter regeneration cannot be implemented. •  Perform applicable DTC troubleshooting then perform compulsory diesel particulate filter regeneration. (See DTC TABLE [PCM (SKYACTIV-D 2.2)])	―	Go to the next step.
13	VERIFY ENGINE OIL LEVEL •  Verify the engine oil level. (See ENGINE OIL LEVEL INSPECTION [SKYACTIV-D 2.2]) •  Is the oil level above the X on the gauge?	Yes	Replace the engine oil. (See ENGINE OIL REPLACEMENT [SKYACTIV-D 2.2]) Implement the engine oil data reset procedure. (See ENGINE OIL DATA RESET [SKYACTIV-D 2.2]) Go to the next step.
		No	Go to the next step.
14	VERIFY THAT REPAIRS HAVE BEEN COMPLETED •  Reconnect all disconnected connectors and hoses. •  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC. (See CLEARING DTC [PCM (SKYACTIV-D 2.2)]) •  Start the engine and drive the vehicle under the freeze frame data/snapshot data condition. Warning •  To prevent an accident, work with another person when the vehicle is being driven (one person drives vehicle, other person operates M-MDS). •  Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured. •  Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) •  Has DTC P2106:00 been recorded?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
		No	Go to the next step.
15	VERIFY OTHER DTCs •  Has any other DTC or pending code been stored?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)])
		No	Referring to each adjustment procedure, perform fuel injection amount learning and the diesel particulate filter data reset. (See FUEL INJECTOR INJECTION AMOUNT CORRECTION [SKYACTIV-D 2.2]) (See DIESEL PARTICULATE FILTER DATA RESET [SKYACTIV-D 2.2]) DTC troubleshooting completed.
