6.1 Driver Assistance Systems Front Camera, Calibrating

Special tools and workshop equipment required 

• Setting Device Basic Set - VAS6430/1-
• Calibration Board For Lane Guard System - VAS6430/4-
• Wheel Alignment Computer
• Vehicle Diagnostic Tester
  NOTE: If the camera can no longer recognize the lane markings due to poor visibility, this could be caused by:

  • The camera visual field is dirty or icy. If that is the problem, it should be corrected.
  • The camera view field in fogged over.

If there is a lot of dirt on the inside of the glass in the camera view window, this must be cleaned off by hand. To do this, remove the control module and the lens and clean the glass with washer fluid. To remove the control module and lens. Refer to Driver Assistance Systems Front Camera, Removing and Installing. 

The calibration must be correct for the Driver Assistance Systems Front Camera - R242- to function correctly. 

The Driver Assistance Systems Front Camera - R242- must be calibrated again for the following reasons: 

• "No or incorrect basic setting/adaptation" is stored in the event memory.
• The Driver Assistance Systems Front Camera - R242- was replaced.
• The windshield was replaced or removed.
• The rear axle toe was adjusted.
• Work was performed on the chassis which influences the body height.
• The vehicle level sensor was readapted on vehicles with damping regulation.
  NOTE:

  • Before calibrating the driver assistance systems front camera, check the Diagnostic Trouble Code (DTC) memory and correct any faults.
  • The driver assistance systems front camera may only be calibrated using alignment equipment approved by VW/Audi.
  • Only the - VAS6430/1- may be used to calibrate the driver assistance systems front camera.
  NOTE:

  • The Driver Assistance Systems Front Camera - R242- must fit correctly in the retainer.
  • The camera viewing range must be clean and unobstructed.
  • Before driving the vehicle onto the vehicle alignment platform, make sure there is sufficient space between the center of the wheel hub on the front wheels and the - VAS6430/1-.
  • The distance between the - VAS6430/1- and the center of the wheel hub on the front wheels must be 1, 500 mm ± 25 mm (59 ± 0.98 in).
  • If there is not sufficient space, drive the vehicle backward onto the alignment stand in order to use the corresponding space.
  • The calibration board must be positioned in the center of the setting device.
  • Before beginning the calibration, check the DTC memory. If necessary, erase any existing entries.
  • Follow the test requirements for an axle alignment. Refer to 3.2 Test Prerequisites.
  • Drive the vehicle onto the vehicle alignment platform.
  • Connect the battery charger. Refer to Battery, Charging.
  • Connect Vehicle Diagnostic Tester (Guide the diagnostic cable through the open window.)
    NOTE: During the calibration procedure, make sure all the vehicle doors remain closed and the vehicle exterior lamps are switched off.
  • Position the front wheels so they are straight.
  • Select calibrating the driver assistance systems front camera in the wheel alignment computer.
  • Install the quick-action clamps on all four wheels.
  • Install the measuring sensors on the wheels.
  • Perform a wheel run-out compensation and the rear wheels.
  • Bounce the vehicle.
  • Measure and record the height at all four wheels.
    NOTE:

    • The -VAS6430/1- must not be moved on the calibration beam.
    • The alignment stand must be in the lowest level position for the next step.

  • Rotate the -VAS6430/1- upward just enough so that the calibration beam is parallel to the center of the measuring sensors on the front wheels, so that it is possible to correctly measure the distance measuring unit

  • Position the -VAS6430/1- at a distance -a- of 1, 500 mm ± 25 mm (59 ± 0.98 in) from the center of the wheel hub on the front wheels to the beam on the -VAS6430/1-.
    CAUTION:

    • Distance -a- 1, 500 mm ± 25 mm (59 ± 0.98 in) must be measured on both side of the vehicle and then the -VAS6430/1- must be aligned.
    • Distance -a- must be the same on both sides of the vehicle.
