― Between push button start terminal B and start stop unit terminal 1AE

― Between start stop unit terminal 2M—Front body control module (FBCM) terminal 2K

― Between start stop unit terminal 2O—Front body control module (FBCM) terminal 2I

― Between front body control module (FBCM) terminal 2P—PCM terminal 2S

― Between front body control module (FBCM) terminal 2N—PCM terminal 2T

• Is there any malfunction?

Yes

Repair or replace the malfunctioning part according to the inspection results.

Go to the next step.

VERIFY PRESENT MALFUNCTION DTC

• Perform the KOEO self test.

(See KOEO/KOER SELF TEST [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [PCM (SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION))].)

Go to the next step.

DETERMINE IF MALFUNCTION CAUSE IS BASE ENGINE OR OTHER

• Inspect for a seized drive plate.

• Is the drive plate seized?

Yes

Repair or replace the malfunctioning part according to the inspection results.

Base engine malfunction or engine damage during compression due to liquid (such as water, fuel, or engine oil) penetration into cylinder.

• Overhaul or replace the engine.

Verify the test results.

• If normal, return to the diagnostic index to service any additional symptoms.

(See SYMPTOM DIAGNOSTIC INDEX [SKYACTIV-G 2.5 (WITH CYLINDER DEACTIVATION)].)

• If the malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform repair or diagnosis.

― If the vehicle is repaired, troubleshooting is completed.

― If the vehicle is not repaired or additional diagnostic information is not available, reprogram the PCM if a later calibration is available. Retest.
