Diagnostic Procedure

STEP

INSPECTION

ACTION
1
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
2
VERIFY DTC FOR MODULE COMMUNICATION
•  Switch the ignition off, then ON (engine off).
•  Perform the DTC Reading Procedure.
•  Are any other PENDING CODEs and/or DTCs present?
Yes
Go to the applicable PENDING CODE or DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
No
Go to the next step.
3
CONFIRM FRONT BODY CONTROL MODULE (FBCM) DTC
•  Perform the front body control module (FBCM) DTC inspection using the M-MDS.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [FRONT BODY CONTROL MODULE (FBCM)].)
No
Go to the next step.
4
CONFIRM INSTRUMENT CLUSTER DTC
•  Perform the instrument cluster DTC inspection using the M-MDS.
•  Are any DTCs present?
Yes
DTC U0100:00 is displayed:
•  CAN communication line can be considered the cause.
―  Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:
•  Instrument cluster terminal B—Front body control module (FBCM) terminal 2K
•  Instrument cluster terminal D—Front body control module (FBCM) terminal 2I
•  Front body control module (FBCM) terminal 2P—PCM terminal 2AK
•  Front body control module (FBCM) terminal 2N—PCM terminal 2AL
If there is a common connector:
•  Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a malfunction.
•  Repair or replace the malfunctioning part.
If there is no common connector:
•  Repair or replace the wiring harness.
•  Go to Step 7.
DTC other than U0100:00 is displayed:
•  Go to the applicable DTC inspection.
No
Go to the next step.
5
INSPECT INSTRUMENT CLUSTER CONNECTOR CONDITION
•  Switch the ignition off.
•  Disconnect the instrument cluster connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 7.
No
Go to the next step.
6
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to the next step.
No
Repair or replace the following wiring harnesses.
•  Instrument cluster terminal B—Front body control module (FBCM) terminal 2K
•  Instrument cluster terminal D—Front body control module (FBCM) terminal 2I
•  Front body control module (FBCM) terminal 2P—PCM terminal 2AK
•  Front body control module (FBCM) terminal 2N—PCM terminal 2AL
―  If the malfunction recurs, replace the instrument cluster.
Go to the next step.
7
VERIFY DTC TROUBLESHOOTING COMPLETED
•  Always reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Perform the KOEO or KOER self test.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
8
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [SKYACTIV-D 2.2].)
No
DTC troubleshooting completed.
