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.
You must carry out tolerance calibration if you do any of the following.
–
Remove and install a wide camera.
–
Conduct a body task that causes the focus of the wide camera to change, such as a trunk task.
–
Replace the door mirror that has a wide camera.
–
Replace the surround view monitoring unit.
Environment that is required to perform compensation task
Tolerance Calibration Procedures
1.
It shall be prepared as follows.
–
Check whether the hood, trunk and door are closed.
–
Close the door after seating on driver seat.
–
Put the power of the car in "IGN (Start)" position.
–
Unfold the mirror when the side mirror is folded.
–
Put the gear to N position.
–
Check ON/OFF of the indication lamp inside the SVM switch.
–
Do not install the device like the air intaker which may block the angle of the rear camera during preparation.
–
In addition, the tolerance calibration procedure shall be
made at IGN (Start) condition after removing the smoke with fan because
the smoke from the exhausting outlet may disturb the rear visioning.
Apply foot brake or electronic parking brake (EPB) for the vehicle not to move.
2.
The following procedure shall be performed to check the
normal operation of SVM ECU and camera before entering into the
tolerance calibration mode.
–
Check whether the initially set screen image is displayed
from SVM. (Front view screen image at gear position at N + Around view
screen image)
–
Check whether the screen image for the front, rear, left and right is normally shown on the around view screen.
–
Enter into the tolerance calibration mode when the screen
image is normally output and replace the corresponding parts when the
output is abnormal or no output.
3.
The equipment and vehicle shall be connected as shown in the
following figure in order to perform the SVM manual screen image
calibration.
4.
Off the ignition power of the vehicle.
5.
Remove the glove box to couple the connector of the GDS-SVM with SVM unit.
(Refer to Body Electrical System - "Surround View Monitoring Unit")
6.
Disconnect the connector (24 pin) coupled from SVM unit to wiring harness on the vehicle.
7.
Connect the connector (24 pin) of the GDS-SVM image capture equipment to the point of SVM unit connector.
It is connected in T shape as shown in the following figure.
The assembling shall be made surely by making clicking sound during connector coupling.
8.
Connect the GDS VCI and vehicle with DLC cable.
VCI and AVM shall be connected to PC with USB cable.
GDS-VCI shall be connected to PC surely with USB cable
because the calibration image data to be transmitted to the AVM
controller.
Do not disconnect 24 pin on SVM controller (ECU) at the state
of ignition (IGN) power ON. (Risk of out of order in control module)
9.
Install the calibration scale (2EA), calibration standard
line board (2EA) and calibration target board (4EA) near to the vehicle
by referring to the enclosed instruction manual.
Align the front wheel center to the calibration standard line board by classifying A-type and B-type.
Special care is needed for the exactness (Distance / right
angle) in centering position of the white and black calibration board is
very important as it is a standard coordinate.
–
The tolerance of front and rear /left and right shall be controlled under 3cm.
–
The rotation error for vehicle alignment shall be controlled within 1 degree to the left and right.
10.
Keep the ignition in ON position at the state of vehicle stop
and check the ''P'' position of gear lever and lock the parking brake
even on the flat ground.
11.
Perform the work with the SVM switch in the vehicle set to ‘ON.’
12.
Perform SVM manual tolerance compensation according to GDS diagnostics display.
13.
The next procedure is to proceed by referring to the GDS
screen instructions and the ‘manual tolerance compensation’ manual
supplied along with the equipment.
