Tolerance compensation compensates for the error margins of
surround view video that occur due to the installation tolerance when
the four cameras comprising the SVM system are installed.
Tolerance compensation must be carried out when the following actions are performed:
–
When removing and installing a wide camera.
–
When conducting a body task such as the trunk task that causes the focus of the wide camera to change.
–
When replacing the door mirror with a wide camera.
–
When replacing the surround view monitoring unit.
Tolerance Compensation Environments
There are two types of tolerance compensations: [manual tolerance compensation] and [automatic tolerance compensation].
The service center with the SVM exclusive workshop performs [automatic tolerance compensation].
The maintenance environment without the SVM exclusive workshop performs [manual tolerance compensation].
The Procedure of Manual Tolerance Compensation
1.
Advanced preparations will be made according to the following.
–
Confirm that the car hood, trunk and door are closed.
–
The door is closed after getting in on the passenger side.
–
Unfold the side mirror if it is folded in.
–
Put the gear into neutral.
–
Confirm that LED turning signals light up by operating the switch.
–
In the preparation stage ahead of time an exhaust inhaler should not be installed as it can block the view of the rear camera.
–
The foot brake or electro-mechanical parking brake should be engaged to prevent the car from moving.
2.
The following processes will be performed to confirm whether
or not the SVM ECU and camera are working properly before engaging
tolerance compensation mode.
–
Confirm that the initial set up video shows up (front view footage while the gear is in neutral + surround view footage).
–
Confirm that footages from the front, back, left and right show up properly.
–
When the footages appear properly, the tolerance compensation
mode will be engaged, and when footages do not show up clearly or do
not show up at all, the parts will have to be replaced.
3.
To perform SVM manual footage compensation the equipment in the figure below must be interconnected with the vehicle.
4.
The vehicle''s ignition (IG) must be turned off.
5.
Remove the Instrument Cluster to connect the connector of the GDS-SVM device to the vehicle''s SVM module.
(Refer to Surround View Monitoring (SVM) System - "Surround View Monitoring Unit")
6.
The wire harness and connecting connector (24 pins) running from the SVM unit to the vehicle side will be removed.
7.
The GDS-SVM Image Capture equipment connector (24-pin) will be connected to the same location as the SVM unit connector.
Listen for a ''click'' when connecting the connector.
8.
The GDS VCI and vehicle are connected by DLC cable.
The VCI and SVM should have a secure connection with the PC using a USB cable.
The GDS-VCI must connect to the PC with a USB cable to transmit compensation image data from the SVM electronic control unit.
When the ignition (IGN) power is switched ON, the 24-pin
connector of the SVM electronic control unit (ECU) should not be removed
(due to risk of causing malfunction in the control module).
9.
Install around the vehicle by referring to the guide that was
provided along with the compensation scales (2), compensation standard
line boards (2), and compensation target boards (4).
When centering the wheels on the compensation standards line board, the A-type and B-type must be centered separately.
Caution should be taken as the center location of the white
and black compensation plates consist of standard coordinates where the
accuracy of distance/right-angles is very important.
–
The front and rear / left and right centering should be maintained within a deviation of 3cm.
–
When centering the vehicle, the rotation deviation should be maintained within 1 degree on the side.
10.
Keep the IG on while the car is stopped, confirm the gear selecter is in Park ''P'' and engage the parking brake on a flat area.
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.
