Diagnostic Procedure

STEP	INSPECTION		ACTION
1	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.
1		No	Go to the next step.
2	INSPECT WHETHER MALFUNCTION IS FUEL RUNOUT OR OTHER • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 2.2].) • Switch the ignition off. • Refill the fuel above 9 L {2 US gal, 2 Imp gal}. • Start the engine and warm it up completely. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) • Is the DTC P115A:00, P0313:00 or P115B:00 present? Note • If the refueling amount is low, the PCM stored DTC P115A:00, P0313:00 or P115B:00 continues.	Yes	Go to the next step.
2		No	Any other PENDING CODEs and/or DTCs are present: • Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 2.2].) Any other PENDING CODEs and/or DTCs are not present: • The cause of this DTC is low fuel level. ― DTC troubleshooting completed.
3	REINSPECT WHETHER MALFUNCTION IS FUEL RUNOUT OR OTHER • Switch the ignition off. • Refill the fuel till fuel level is above 9 L {2 US gal, 2 Imp gal}. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 2.2].) • Switch the ignition off. • Refill the fuel above 9 L {2 US gal, 2 Imp gal}. • Start the engine and warm it up completely. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) • Is the DTC P115A:00, P0313:00 or P115B:00 present?	Yes	Inspect the fuel gauge. (See INSTRUMENT CLUSTER INSPECTION.) • Repair or replace the malfunctioning part according to the inspection results, then go to the next step. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
3		No	Any other PENDING CODEs and/or DTCs are present: • Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 2.2].) Any other PENDING CODEs and/or DTCs are not present: • The cause of this DTC is low fuel level. ― DTC troubleshooting completed.
4	VERIFY DTC TROUBLESHOOTING COMPLETED • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 2.2].) • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
4		No	Go to the next step.
5	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [SKYACTIV-D 2.2].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 2.2].)
5		No	DTC troubleshooting completed.
