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

  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 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.
