Diagnostic Procedure

Step

Inspection

Results

Action

1

INSPECT ENGINE OIL LEVEL

•  Inspect the engine oil level.
(See ENGINE OIL LEVEL INSPECTION [SKYACTIV-D 1.8].)

•  Is the engine oil level normal?

Yes

Go to the next step.

No

If the engine oil level is below or near the L mark:

•  Add genuine motor oil, then go to the next step.

If the engine oil level is close to or exceeds the X mark:

•  Replace the engine oil.
(See ENGINE OIL REPLACEMENT [SKYACTIV-D 1.8].)

Perform the ENGINE OIL DATA RESET, then go to repair completion verification.

(See ENGINE OIL DATA RESET [SKYACTIV-D 1.8].)

2

VERIFY PCM DTC

•  Retrieve PCM DTCs using the M-MDS.
(See DTC INSPECTION.)

•  Are any DTCs present?

Yes

Go to the applicable DTC inspection.

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

No

Go to the next step.

3

VERIFY IF ENGINE OIL WARNING LIGHT ILLUMINATES

•  Start the engine.

•  Increase and keep the engine speed at 2,500 rpm for 15 s.

•  Does the engine oil warning light illuminate?

Yes

Go to the next step.

No

Symptom troubleshooting is completed. (Explain contents of repair to customer.)

4

INSPECT INSTRUMENT CLUSTER FOR MALFUNCTION

•  Inspect the applicable part.
(See INSTRUMENT CLUSTER INSPECTION [(E)].)

•  Is the part normal?

Yes

Go to the next step.

No

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

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

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

•  Has the malfunction symptom been eliminated?

Yes

Complete the symptom troubleshooting. (Explain contents of repair to customer)

No

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, go to the next step.

Repair completion verification 2

VERIFY IF MALFUNCTION IS CAUSED BY NOT PERFORMING PCM REPROGRAMMING

•  Verify repair information and verify that there is a new calibration in the PCM.

•  Is there a new calibration in the PCM?

Yes

Perform the PCM reprogramming and verify if the malfunction symptom was corrected.

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

No

Replace the PCM.

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