Rearview Camera System, Calibrating
Calibration Unit -VAS6350A-, Installing and Aligning
After performing service work on the vehicle, it may be necessary to re-calibrate the rearview camera system. In detail, this is the case after:
Calibration Requirements
Special tools and workshop equipment required
The Calibration Unit -VAS6350A- consists of the following parts:
Installed Calibration Unit -VAS6350A- Overview
1 - Calibration Tool - Wheel Center Mountings -VAS6350/1-
2 - Calibration Tool - Wheel Center Mountings -VAS6350/1-
3 - Right Angle Bracket
4 - Plastic Foot
5 - Calibration Tool - Linear Laser -VAS6350/3-
6 - Calibration Tool - Spacing Laser -VAS6350/2-
7 - Level
8 - Left Angle Bracket
9 - Calibration Board
Calibration Board Orientation
- Position the calibration platform behind the vehicle at a distance of 1.47 m to 1.90 m to the rear wheels, see -dimension A- in the illustration.
- Bring the Calibration Unit -VAS6350A- into a horizontal position.
- Twist the plastic feet under the calibration board so that the air bubble in the level is located exactly in the center of the indicator -arrow-.
WARNING
Make sure light does not reflect off the calibration board.
Reflections affect the Rearview Camera -R189- and may make it impossible to perform the calibration.
- Switch on the Calibration Tool - Linear Laser -VAS6350/3--1- on the calibration board and adjust the entire Calibration Unit -VAS6350A- so that the laser beam hits the center of vehicle rear above the Audi rings.
- Make sure the Audi rings are centered on the rear. Correct the laser beam accordingly.
Continue calibrating the Rearview Camera -R189-. Refer to → Chapter "Rearview Camera -R189-, Calibrating".
Rearview Camera -R189-, Calibrating
- Establish the requirements.
- Connect the Vehicle Diagnostic Tester.
Calibration Tool - Wheel Center Mountings -VAS6350/1- installing:
- Check the dimension of the holes.
- Equip the Calibration Tool - Wheel Center Mountings -VAS6350/1- appropriately. Use spacer pieces.
- To do so, secure three wheel bolt adapters in the hole circle to each Calibration Tool - Wheel Center Mountings -VAS6350/1-.
- Place the paddle on both Calibration Tool - Wheel Center Mountings -VAS6350/1- and secure them using a clamping screw.
- Place the Calibration Tool - Wheel Center Mountings -VAS6350/1- onto the wheel bolts on the rear wheels.
The Calibration Tool - Wheel Center Mountings -VAS6350/1- are positioned by the "O-rings" in the adapters and secured.
Note
Attach the Calibration Tool - Wheel Center Mountings -VAS6350/1- onto the wheels so that any installed "anti-theft" wheel mounting bolts are not connected to the Calibration Tool - Wheel Center Mountings -VAS6350/1-.
- Adjust the paddles with aid of lock bolts so that they move freely just above the floor. Check the paddles for ease of movement.
- Install and align the Calibration Unit -VAS6350A-. Refer to → Chapter "Calibration Unit -VAS6350A-, Installing and Aligning".
Distance measurement:
- Switch on the Calibration Tool - Spacing Laser -VAS6350/2-.
The Following Display Appears
The display shows how to stop the Calibration Tool - Spacing Laser -VAS6350/2-. Press the corresponding button.
1 - Attach with front edge
2 - Attach with rear edge
- Hold the Calibration Tool - Spacing Laser -VAS6350/2--2- flush in the bracket on one side of the calibration board (attach with rear edge). The Calibration Tool - Spacing Laser -VAS6350/2--2- must sit securely on the bracket.
- Press the measuring button briefly.
The laser switches on.
- Make sure that laser beam from Calibration Tool - Spacing Laser -VAS6350/2--2- hits lower, enlarged part of paddle -1-.
If this is not the case, the paddles must be corrected accordingly via clamping screws on the Calibration Tool - Wheel Center Mountings -VAS6350/1-.
- Use one hand to secure the Calibration Tool - Spacing Laser -VAS6350/2- in the bracket on the Calibration Tool -VAS6350- while the laser beam is visible on the paddle.
- Then press the measurement button for the distance measurement briefly.
- Write down the value.
- Repeat this measurement on the other side of the Calibration Tool -VAS6350- in the same way for the rear wheel.
The distance value must be the same on both sides.
If values are not identical:
- Align the Calibration Unit -VAS6350A- long enough so that both sides are identical.
Pay attention when aligning the Calibration Tool -VAS6350-, that the Calibration Tool - Linear Laser -VAS6350/3- from the Calibration Tool -VAS6350- strikes the center of the Audi rings and the indicator of the level remains centered. Adjust if necessary.
Measurement -dimension H-:
- Measure the height of the Calibration Tool -VAS6350-, -dimension H- (top edge platform - floor).
Make sure the Calibration Tool - Spacing Laser -VAS6350/2- is adjusted correctly (attach with front edge).
The display shows how to stop the Calibration Tool - Spacing Laser -VAS6350/2-. Press the corresponding button.
1 - Attach with front edge
2 - Attach with rear edge
