Kia Sorento: Wide Angle Camera Adjustment
Tolerance Calibration Outline.
Tolerance calibration compensates for the error margins of surround view video that occur due to the installation
tolerance when the four cameras that comprise the SVM system are installed.
|
Tolerance calibration must be performed when the following actions are
performed.
|
–
|
When conducting a body task that causes the focus of the wide angle camera changes.
|
|
–
|
When replacing the ADAS Parking ECU.
|
|
–
|
When a failure code (System Out of Calibration) occurs.
|
|
Tolerance Calibration Environments
|
SVM calibration tool is required to perform tolerance calibration as shown below.
|
Manual Tolerance Calibration Procedure
| 1. |
Prepare in advance as below.
|
–
|
Confirm that the car hood, trunk and doors are closed.
|
|
–
|
Close the door after getting in on the driver side.
|
|
–
|
Unfold outside rear view mirrors.
|
|
–
|
Shift the gear to the 'N'.
|
|
–
|
During the advance preparation, do not install exhaust inhaler or other equipment that may block
the view of rearview cameras.
|
|
–
|
Engage foot brake or electronic parking brake (EPB) to hold vehicle in place.
|
|
| 2. |
Before entering tolerance calibration mode, to check normal operation of SVM ECU and cameras, perform the
following.
|
–
|
Check that initial setting screen of SVM is displayed. (Front view image + surround view image when
shifted to N)
|
|
–
|
Check that front, rear, left and right images of surround view monitor are properly displayed.
|
|
–
|
If images are properly displayed, enter tolerance calibration mode. Otherwise, if images are
abnormally displayed or are not displayed, replace relevant part.
|
|
| 3. |
Install two calibration scales, two calibration reference line boards, and four calibration target boards
around the vehicle by referring to the manual provided with the tools.
|
•
|
There are two types (Type A & B) and the base line should be matched to vehicle type.
|
|
•
|
Accurately set the location (distance/angle) of the center of white and black calibration
board as this is the reference point.
|
|
| (1)
|
Align the vehicle in a straight line and install the SVM ruler on the front and rear tires in the
direction of the arrow.
|
| (2)
|
To align the center point of the vehicle, install the calibration ruler by moving it from side to
side so that the calibration ruler dimensions below the tires on the right and left sides are the
same.
|
•
|
Be careful not to crease when installing the SVM ruler.
|
|
•
|
The measurements on both sides should be the same.

|
If the user is equipped with tires of different dimensions than the specification,
the results of the SVM tolerance correction work may not be accurate.
|
|
•
|
The dimensions of the front and rear tires may be different.
|
|
|
| (3)
|
The SVM reference line should be installed according to the end point of SVM ruler.
|
•
|
Align the right-front wheel center of the tire with the base line on the SVM
reference line.
|
|
•
|
There are two types(Type A & B) and the Base line should be matched to vehicle
type.
|
|
•
|
Base line margin of error should be 3 cm (1.1 in.)
|
|
•
|
Measure the margin of error at the end of the baseline (A).
|
|
|
Install it in the same way on the left hand side.
|
|
| (4)
|
After installing the calibration ruler and the calibration reference line, verify that the left and
right calibration reference lines are installed parallel to each other.
|
•
|
If the distance between left and right is the same back and forth, the calibration
reference line is normally installed.
|
|
•
|
The error range of the calibration reference line left/right distance shall be 299
to 301 cm (117.7 ~ 118.5 in).
|
|
|
| (5)
|
Install the SVM target on the SVM reference line.
|
•
|
The angle between the SVM calibration reference line and the SVM calibration target
shall be 90 degrees.
|
|
•
|
Rotation error when aligning vehicle should be within 1° to left/right.
|
|
|
|
| 4. |
Maintain IG ON with vehicle stopped, check that the gear is in P, and engage parking brake even on flat
ground.
|
| 5. |
Work is carried out with the parking/view button ON.
|
| 6. |
Perform the order below with the KDS.
