Diagnostic Procedure

Step

Inspection

Results

Action

1

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.

2

INSPECT FOR FUEL LEAKAGE FROM FUEL SYSTEM

•  Visually inspect the following:

―  Fuel leakage from the fuel tank, fuel pump, hose, pipe, fuel injector, supply pump, common rail

―  Cracking and damage in fuel hose and pipe

―  Clamp installation condition for each hose and pipe

―  Fuel pipe securing condition due to deterioration such as rubber of clamp

•  Are all items normal?

Yes

Go to the next step.

No

Repair or replace the malfunctioning part according to the inspection results, then go to the next step.

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].)
