Diagnostic Procedure

STEP

INSPECTION

RESULTS

ACTION

1

VERIFY PCM DTC

•  Retrieve PCM DTCs using the M-MDS.
(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].)

•  Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [PCM (SKYACTIV-D 2.2)].)

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.)

•  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 Step 6.

3

INSPECT BLOW-BY HEATER

•  Inspect the blow-by heater.
(See BLOW-BY HEATER INSPECTION [SKYACTIV-D 2.2].)

•  Is the blow-by heater normal?

Yes

Go to the next step.

No

Replace the blow-by heater, then go to the next step.

(See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

4

INSPECT FOR MALFUNCTION DUE TO DEVIATED VALVE TIMING

•  Inspect the valve timing (timing chain installation condition).
(See TIMING CHAIN REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)

•  Is the valve timing normal?

Yes

Go to the next step.

No

Adjust the valve timing to the correct timing, then go to Step 6.

5

INSPECT INSTRUMENT CLUSTER

•  Inspect the instrument cluster.
(See INSTRUMENT CLUSTER INSPECTION.)

•  Is the instrument cluster normal?

Yes

Go to the next step.

No

Replace the instrument cluster, then go to the next step.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

6

Verify the test results.

•  If normal, return to the diagnostic index to service any additional symptoms.
(See SYMPTOM DIAGNOSTIC INDEX [SKYACTIV-D 2.2].)

•  If a malfunction remains, inspect the related Service Information and perform the repair or diagnosis.

―  If the vehicle is repaired, troubleshooting is completed.

―  If the vehicle is not repaired or additional diagnostic information is not available, replace the PCM.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
