Audi A4: Peripheral Camera, Calibrating

Calibration System -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 (0.39 in.)

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.

  Note

The vehicle in the illustration is only a basic outline.

Requirements for the Calibration Equipment/Calibration Environment

1 - Left Calibration Device

2 - Front Peripheral Camera -R243-

  • Calibrating. Refer to → Chapter "Peripheral Camera System, Calibrating".

3 - Right Calibration Device

4 - Right Peripheral Camera -R245-

  • Calibrating. Refer to → Chapter "Peripheral Camera System, Calibrating".

5 - Rear Peripheral Camera -R246-

  • Calibrating. Refer to → Chapter "Peripheral Camera System, Calibrating".

6 - Left Peripheral Camera -R244-

  • Calibrating. Refer to → Chapter "Peripheral Camera System, Calibrating".

Peripheral Camera System, Calibrating

- The vehicle must be on a level surface.

  Note

The vehicle in the illustration is only a basic outline.

- Roll out the Calibration System -VAS721001- at the left and right near the vehicle.

- Install the rear and front clamping strip on the Calibration System -VAS721001-.

- Align the crosshairs -2- 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  +- 2 mm (78.74 to 98.4 +- 0.07 in.), 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

- Set-up the requirement for the vehicle.

- Connect the Vehicle Diagnostic Tester.

Calibrating Procedure

- Select the Diagnostic mode and start the diagnosis.

- Select the Test plan tab.

- Press the Select individual test 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.
