Diagnostic Work SheetINFOID:0000000009464819
DESCRIPTION
In general, each customer feels differently about an inci dent. It is important to fully understand the symptoms
or conditions for a customer complaint.
There are many operating conditions that lead to the malfunction. A good grasp of such conditions can make
troubleshooting faster and more accurate.
Some conditions may cause the lane departure warning lamp to stay ON.

REAR VIEW CAMERA CALIBRATION
REAR VIEW CAMERA CALIBRATION
DescriptionINFOID:0000000009464825
Always perform the calibration after removing and installing or replacing the rear view camera.
CAUTION:
• Place the vehicle on level ground wh en the calibration is performed.
• Follow the CONSULT when performing the calib ration. (Rear view camera calibration cannot be
operated without CONSULT).
Work Procedure (Preparation)INFOID:0000000009464826
1.PERFORM SELF-DIAGNOSIS
Perform self-diagnosis of the ITS control unit.
Is any DTC detected?
Except "U1308">> Perform diagnosis on the detected DTC and repair or replace the applicable item. Refer to
DAS-164, "DTC Index"
.
"U1308" or no DTC>>GO TO 2.
2.PREPARATION BEFORE REAR VIEW CAMERA CALIBRATION
NOTE:
Select the "AVM" to diagnose the ITS control unit by CONSULT.
1. Perform pre-inspection for diagnosis. Refer to DAS-158, "CONSULT Function (AVM)"
.
2. Adjust the tire pressure to the specified pressure value.
3. Maintain no-load in vehicle.
4. Check if coolant and engine oil are filled up to correct level and fuel tank is full.
5. Situate vehicle where the camera is ex posed at an atmosphere temperature between 0 °C (32 °F) and
30 °C (86 °F)
6. Move the shift selector to P (Park) and release the parking brake.
7. Clean the rear view camera.
>> GO TO 3.
3.PREPARATION OF CALIBRATION TARGET MARK
Prepare the calibration target mark according to the following figure:
ALOIA0186ZZ
(1) : Left and right targets
(2) : Center target
(A) : Side of the black or white area = 200 mm (7.87 in)
(B) : Side of the square target = 400 mm (15.75 in)
