― Verify if malfunctioning part is PCM.

• Step 2

― Verify that there are no other malfunctions.

STEP

INSPECTION

RESULTS

ACTION

1

PURPOSE: 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.

2

PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS PCM

•  Clear the DTC from the PCM memory using the M-MDS.
(See CLEARING DTC [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

•  Perform the KOER self test.
(See KOEO/KOER SELF TEST [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

•  Is the same DTC present?

Yes

Replace the PCM, then go to the next step.

(See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

No

Go to the next step.

3

PURPOSE: VERIFY IF THERE IS ANY OTHER MALFUNCTION

•  Is any other DTC or pending code stored?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

No

DTC troubleshooting completed.
