DIAGNOSIS SYSTEM (ITS CONTROL UNIT)
CONSULT Function (AVM)INFOID:0000000009464652
CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and no-start condition.
APPLICATION ITEMS
CONSULT performs the following functions via CAN communication using ITS control unit.
SELF DIAGNOSTIC RESULT
Refer to DAS-20, "DTC Index".
DATA MONITOR
Diagnosis mode Description
Self Diagnostic Result Displays the name of a malfunctioning system stored in the ITS control unit
Data Monitor Displays ITS control unit input/output data in real time
Work support Displays causes of automatic system cancellation occurred during system control
Active Test Enables an operational check of a load by transmitting a driving signal from the ITS control unit to
the load

.
Work Procedure (Rear View Camera Calibration)INFOID:0000000009464668
CAUTION:
Perform the calibration under the sp ecified vehicle condition (fuel full, no-load, specified tire pressure,
etc.). Refer to DAS-38, "Work Procedure (Preparation)"
.
1.CHECK REAR VIEW CAMERA HEIGHT
Measure the rear view camera height “H”.
>> GO TO 2.
2.REAR VIEW CAMERA CALIBRATION
1. Select “Work Support” on “AVM” with CONSULT.
2. Select “REAR CAMERA ITS”.
3. Select "OK". CAUTION:
• Perform the calibration after the ignition or engine has been kept on for at least 10 minutes to
stabilize camera.
• Operate CONSULT outside the vehicle, and close al l doors to retain appropriate vehicle altitude.
4. Input the rear view camera height "H", and then touch "APPLY".
5. Confirm that the same value is displayed on the center display.
6. Confirm the following items:
- The target should be accurately placed.
- The vehicle should be stopped.
- The vehicle should be under the specified vehicle condition.
7. Select “Start” to perform calibration.
8. Confirm the displayed item.
- “Completed”: Select “Completion”.
