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 BLOW-BY HEATER RELAY FOR MALFUNCTION

•  Switch the ignition off.

•  Remove the blow-by heater relay.
(See RELAY LOCATION [(E)].)

•  Inspect the blow-by heater relay.
(See RELAY INSPECTION.)

•  Is the blow-by heater relay normal?

Yes

Go to the next step.

No

Replace the blow-by heater relay, then go to repair completion verification.

3

INSPECT BLOW-BY HEATER FOR MALFUNCTION

•  Inspect the applicable part.
(See BLOW-BY HEATER 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 INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

4

INSPECT FOR MALFUNCTION DUE TO DEVIATED VALVE TIMING

•  Inspect the valve timing (timing chain installation condition).
(See TIMING CHAIN REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

•  Is the valve timing normal?

Yes

Go to the next step.

No

Adjust the valve timing to the correct timing, then go to repair completion verification.

5

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].)
