WARNING:
Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly push down and
turn it a quarter turn to allow built-up pressure to escape. Carefully remove the cap by pushing it down
and turning it all the way.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.

REAR VIEW CAMERA CALIBRATION
REAR VIEW CAMERA CALIBRATION
DescriptionINFOID:0000000009464665
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:0000000009464666
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-20, "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-34, "Inspection Procedure"
.
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)
