STEP	INSPECTION	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 RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
No	Go to the next step.
3	VERIFY RELATED PENDING CODE AND/OR DTC • Switch the ignition off, then ON (engine off). • Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Are any other PENDING CODEs and/or DTCs present?	Yes	If DTC P243C is stored • Repair the malfunctioning location according to the applicable DTC troubleshooting, then go to the next step. (See DTC P243C:00 [SKYACTIV-D 1.5].) If DTC other than P243C is stored • Repair the malfunctioning location according to the applicable DTC troubleshooting, then go to the next step. (See DTC TABLE [SKYACTIV-D 1.5].)
No	Go to the next step.
4	VERIFY VALUE OF PID DET_CNT_L1 (INTERVAL FOR NUMBER DIESEL PARTICULATE FILTER REGENERATIONS IS 39—69 KM {25—42 MILE}) USING M-MDS • Access the DET_CNT_L1 PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Is the value indicated for DET_CNT_L1 44 times or more?	Yes	Go to the next step.
No	Replace the fuel injector in all of the cylinders, then go to the next step. (See FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
5	VERIFY VALUE OF PID DET_CNT_L2 (INTERVAL FOR NUMBER DIESEL PARTICULATE FILTER REGENERATIONS IS 70—99 KM {44—61 MILE}) USING M-MDS Note • If the value of PID DET_CNT_L1 is 44 times or less under the vehicle detection condition of DTC P2459:00, the value of PID DET_CNT_L2 is 115 times or more. • Access the DET_CNT_L2 PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) • Verify that the value of DET_CNT_L2 is 115 times or more.	—	Go to the next step.
6	PERFORM FUEL INJECTOR CARBON DEPOSIT BURN-OFF PROCEDURE Note • Carbon on the exhaust valve is removed by performing the fuel injector carbon deposit burn-off procedure. • Perform the "FUEL INJECTOR CARBON DEPOSIT BURN-OFF PROCEDURE". (See FUEL INJECTOR CARBON DEPOSIT BURN-OFF PROCEDURE [SKYACTIV-D 1.5].)	—	Go to the next step.
7	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-D 1.5].)	—	DTC troubleshooting completed.
