Inspection

Results

Action

1

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 DTC P0313:00 or P115B:00 been recorded?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC P0313:00 [PCM (SKYACTIV-D 2.2)].)

(See DTC P115B:00 [PCM (SKYACTIV-D 2.2)].)

No

Go to the next step.

2

DETERMINE IF MALFUNCTION IS DUE TO OUT OF FUEL

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.
(See CLEARING DTC [PCM (SKYACTIV-D 2.2)].)

•  Switch the ignition OFF.

•  Add 9 L or more of fuel.

•  Start the engine and warm it up.

•  Display the DTCs using the M-MDS.
(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].)

•  Is DTC P115A:00 displayed?

Note

•  If the added fuel is low, the PCM continues to record DTC P115A:00.

Yes

Go to the next step.

No

If other DTC or pending code is displayed:

•  Repair the malfunctioning location according to the applicable DTC troubleshooting.
(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)

If other DTC or pending code is not displayed:

•  Malfunction due to lack of fuel

―  DTC troubleshooting completed.

3

DETERMINE IF MALFUNCTION IS DUE TO OUT OF FUEL AGAIN

•  Switch the ignition OFF.

•  Add fuel until the fuel level reaches 9 L or more.

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.
(See CLEARING DTC [PCM (SKYACTIV-D 2.2)].)

•  Switch the ignition OFF.

•  Add 9 L or more of fuel.

•  Start the engine and warm it up.

•  Display the DTCs using the M-MDS.
(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].)

•  Is DTC P115A:00 displayed?

Yes

Perform the fuel gauge inspection.

(See INSTRUMENT CLUSTER INSPECTION.)

No

If other DTC or pending code is displayed:

•  Repair the malfunctioning location according to the applicable DTC troubleshooting.
(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)

If other DTC or pending code is not displayed:

•  Malfunction due to lack of fuel

―  DTC troubleshooting completed.

4

VERIFY THAT REPAIRS HAVE BEEN COMPLETED

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.
(See CLEARING DTC [PCM (SKYACTIV-D 2.2)].)
