Audi Q7: Peripheral Camera, Calibrating
Calibration Device - VAS721001-, Installing and Aligning
After performing service work on the vehicle, it may be necessary to calibrate the peripheral camera system. In detail, this is the case after:
- Replacing one or more cameras
- Peripheral Camera Control Module -J928- replacement
- Flash the software from the Peripheral Camera Control Module -J928-
- Record the data set on the Peripheral Camera Control Module -J928-
- Repair work on components in which a camera is installed or that influence the component location of the camera
- Wheel Alignments
- When adjusting the overlap range of the individual cameras
- The standing height of one axle changes by more than 5 mm
- The standing height of the entire vehicle changes by more than 10 mm
Requirement for the Calibration of the Vehicle
- Camera lens must be cleaned, only clean the camera lenses with a wet towel.
- Check the camera images on the Front Information Display Control Head -J685-. Replace the camera if the images are unclear because the camera has been damaged. Check the fastener for the camera if the image is low.
- Make sure both exterior rearview mirrors are folded out.
- The parking brake must be set.
- The steering wheel must be in the 0 position and the wheels must be straight.
- All doors and the rear lid must be closed.
- No one should be in the vehicle.
- The vehicle must not be loaded (curb weight).
- The battery charger is connected, the battery charger must not be in the view of the camera.
- Ignition switched on.
- The system is active and is displayed on the Front Information Display Control Head -J685-.
- Do not move the vehicle during the calibration process.
Requirements for the Calibration Equipment/Calibration Environment
- flat calibration surface
- Do not use any objects in the environment of the calibration field, to prevent a false recognition of lines
- Even light (no headlamps or direct illumination), prevent strong light differences
Special tools and workshop equipment required
- Calibration System -VAS721001-
- Vehicle Diagnostic Tester
Overview of the Installed Calibration System -VAS721001-.
WARNING
Make sure light does not reflect off the Calibration System -VAS721001-.
Reflections affect the camera and may make it impossible to perform the calibration.

Peripheral Camera, Calibrating
- The vehicle must be on a level surface.
- Set-up the requirements for the calibration equipment/calibration environment.
- Set-up the requirement for the vehicle.
- Roll out the Calibration System -VAS721001- at the left and right near the vehicle.
- The arrows -1- in the Calibration System -VAS721001- points in the direction of travel.
- Install the rear and front clamping strip on the Calibration System -VAS721001-.
- Align the crosshairs -2- on the Calibration System -VAS721001- to the front axle of the vehicle (center front wheel).
- Align both calibration devices parallel. The vehicle must be located in the center between both calibration devices.
Pay attention to the following measurement requirements:
- Dimension -a- 2000 to 2500 mm +- 5 mm, front and rear the same
- The dimension -b- must be the same on both sides
- The dimension -c- must be the same on both sides
- Connect the Vehicle Diagnostic Tester.
Calibrating
- Select the Diagnostic mode and start the diagnosis.
- Select the Test plan tab.
- Press the Select individual tests button and select the following one after the other:
- Body
- Electrical Equipment
- 01 - OBD-capable systems
- 6C - peripheral camera control module | J928
- 6C - peripheral camera control module, functions
- 6C - Calibration, (Repair Group 91)
From here, the Vehicle Diagnostic Tester advances the calibration procedure forward.
WARNING
Make sure light does not reflect off the Peripheral Camera Calibration Device -VAS6350/6-.
Reflections affect the camera and may make it impossible to perform the calibration.
