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	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 2.2].) • Is the PENDING CODE/DTC P0313:00 or P115B:00 also present?	Yes	Go to the applicable PENDING CODE or DTC inspection. (See DTC P0313:00 [SKYACTIV-D 2.2].) (See DTC P115B:00 [SKYACTIV-D 2.2].)
2		No	Go to the next step.
3	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 present? Note • If the refueling amount is low, the PCM stored DTC P115A:00 continues.	Yes	Go to the next step.
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	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 present?	Yes	Go to the next step.
4		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.
5	INSPECT FUEL GAUGE • Inspect the fuel gauge. (See INSTRUMENT CLUSTER INSPECTION.) • Is there any malfunction?	Yes	Replace the instrument cluster, then go to step 7. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
5		No	Go to the next step.
6	INSPECT FUEL GAUGE SENDER UNIT • Inspect the fuel gauge sender unit. (See FUEL GAUGE SENDER UNIT INSPECTION.) • Is there any malfunction?	Yes	Replace the fuel gauge sender unit, then go to the next step. (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION.)
6		No	Go to the next step.
7	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].)
7		No	Go to the next step.
8	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].)
8		No	DTC troubleshooting completed.
