STEP

INSPECTION

RESULTS

ACTION

1

PURPOSE: DETERMINE INTEGRITY OF BARO SENSOR

•  Inspect the BARO sensor.
(See BAROMETRIC PRESSURE (BARO) SENSOR INSPECTION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

•  Is there any malfunction?

Yes

Replace the PCM, then go to the next step.

(See PCM REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

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 1.3, SKYACTIV-G 1.5].)

•  Perform the KOEO or KOER self test.
(See KOEO/KOER SELF TEST [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

•  Is the same DTC present?

Yes

Replace the PCM, then go to the next step.

(See PCM REMOVAL/INSTALLATION [SKYACTIV-G 1.3, SKYACTIV-G 1.5].)

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 1.3, SKYACTIV-G 1.5].)

No

DTC troubleshooting completed.
