Diagnostic Procedure

STEP

INSPECTION

ACTION
1
RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION
Note
•  Recording can be facilitated using the screen capture function of the PC.
•  Record the Snapshot data on the repair order.

Go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Bulletins and/or on-line repair information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available repair information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY DOSING CONTROL UNIT RELATED DTC
•  Retrieve dosing control unit DTCs using the M-MDS.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [DOSING CONTROL UNIT (SKYACTIV-D 2.2)].)
No
Go to the next step.
4
VERIFY AdBlue® AMOUNT IN UREA TANK
•  Access the RRDC_AG_RMN PID using the M-MDS.
•  Is the RRDC_AG_RMN PID value 90% or less?
Yes
Go to the next step.
No
Drain the AdBlue® until it reaches 90% or less.
(See AdBlue® REPLACEMENT [SKYACTIV-D 2.2].)
Then go to Step7.
5
INSPECT UREA TEMPERATURE SENSOR
•  Inspect the urea tempereture sensor.
•  Is there any malfunction?
Yes
Replace the urea tempereture sensor, then go to Step 7.
(See UREA TEMPERATURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
Go to the next step.
6
INSPECT UREA QUALITY SENSOR (QUALITY SENSOR TEMPERATURE)
•  Inspect the urea quality sensor (quality sensor temperature).
•  Is there any malfunction?
Yes
Replace the urea quality sensor, then go to the next step.
(See UREA QUALITY SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
No
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.
•  Maintain the following conditions for 20 s or more.
―  Switch the ignition ON (engine off).
―  Vehicle is stopped. (Vehicle speed: 1 km/h {0.6 mph} or less)
―  Wait for 5 s with the AdBlue® temperature (PID: S_UR_TANK_TMP) at -3 °C {27 °F} or more.
•  Verify the instrument cluster display content.
•  Are SCR system related warnings displayed in the instrument cluster?
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 [PCM (SKYACTIV-D 2.2)].)
No
DTC troubleshooting completed.
