Audi Q7: Rearview Camera System
General Information - Rearview Camera System
The rear view camera system (KA2) assists the driver during back-up driving by providing the driver with an image of the traffic situation behind the vehicle via the Front Information Display Control Head -J685-.
The rear view camera system is switched on when engaging the reverse gear. The system can be activated manually by pressing the Parking Aid Button -E266- in the center console (optional).
The rear view camera system consists of the following components:
- Rearview Camera -R189-
- The Rearview Camera System Control Module -J772- is integrated in the Rearview Camera -R189-
- Information Electronics Control Module 1 -J794-
- Front Information Display Control Head -J685-
Other control modules may be installed as optional equipment.
It is not permitted to install an auxiliary license plate for vehicles with rear view camera system as it could impair the function of the rear view camera system.
Fault Finding is performed using the "Guided Fault Finding" on the Vehicle Diagnostic Tester.

Continue calibrating the Rearview Camera -R189-. Refer to → Chapter "Rearview Camera, Calibrating".
Rearview Camera, 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 the 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".

- 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.
Dimension measurement -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.
