Diagnostic Procedure

Step

Inspection

Results

Action

1

RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION

•  Record the freeze frame data/snapshot data.

Note

•  Recording can be facilitated using the screen capture function of the PC.

—

Go to the next step.

2

VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY

•  Verify related Service Bulletins, on-line repair information, or Service Information availability.

•  Is any related Information available?

Yes

Perform repair or diagnosis according to the available information.

•  If the vehicle is not repaired, go to the next step.

No

Go to the next step.

3

INSPECT FOR OTHER RELATED DTCs

•  Perform the DTC inspection for the PCM.
(See DTC INSPECTION.)

•  Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [PCM (SKYACTIV-D)].)

No

Go to the next step.

4

INSPECT DLC-2 CONNECTOR FOR MALFUNCTION

•  Inspect the applicable connector and terminal.
(See CONNECTOR INSPECTION.)

•  Are the connector and terminal normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification.

5

INSPECT FUEL INJECTOR FOR MALFUNCTION

•  Inspect the applicable part.
(See FUEL INJECTOR INSPECTION [SKYACTIV-D 1.8].)

•  Is the part normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning location and perform the repair completion verification.

(See FUEL INJECTOR REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

6

PERFORM FUEL INJECTION LEARNING

•  Perform the fuel injection learning.
(See FUEL INJECTOR INJECTION AMOUNT CORRECTION [SKYACTIV-D 1.8].)

•  Start the engine.

•  Verify the warning/indicator light condition.

•  Do the warning/indicator lights turn off?

Yes

Go to the next step.

No

Verify that the implementation conditions for fuel injection amount learning are met, and perform the PCM fuel injection amount learning again.

(See FUEL INJECTOR INJECTION AMOUNT CORRECTION [SKYACTIV-D 1.8].)

Go to the next step.

7

VERIFY DTCs

•  Reconnect all disconnected connectors and hoses.

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.

―  Perform the KOEO or KOER self-test.
(See DTC INSPECTION.)

•  Perform the DTC inspection for the PCM.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Repeat the inspection from Step 1.

•  If a malfunction occurs, change the learning method (use/do not use M-MDS), and perform the fuel injection amount learning again.
(See FUEL INJECTOR INJECTION AMOUNT CORRECTION [SKYACTIV-D 1.8].)

Go to the next step.

No

Go to Repair completion verification 2

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

•  Install/connect the part removed/disconnected during the troubleshooting procedure.

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.

―  Perform the KOEO or KOER self-test.
(See DTC INSPECTION.)

•  Perform the DTC inspection for the PCM.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)

If the CAN communication is normal, perform the diagnosis from Step 1.

•  If the malfunction recurs, replace the PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

No

Go to the next step.

Repair completion verification 2

VERIFY IF OTHER DTCs DISPLAYED

•  Perform the DTC inspection.
(See DTC INSPECTION.)

•  Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
