Volkswagen Golf Service & Repair Manual: Front camera for driver assist systems

Calibrating front camera for driver assist systems

  Note
The following situations can cause the camera function to be impaired by sustained poor visibility of the lane marker lines:
The field of view of the camera is soiled or iced over. In this case, clean the affected area.
The field of view of the camera is fogged over.
The camera aperture must be cleaned manually if there is heavy soiling on the inside of the windscreen in the field of view of the camera. To do this, the control unit and lens hood must be removed and the windscreen cleaned using cleaning solution. Remove control unit and lens hood → Electrical system; Rep. gr.96.
Correct calibration is a basic precondition for the front camera for driver assist systems -R242- to function without faults.
The front camera for driver assist systems -R242- must be recalibrated if:
“No or incorrect basic setting/adaptation” entry stored in the event memory.
The front camera for driver assist systems -R242- was replaced.
Windscreen has been renewed or removed.
Rear axle toe setting has been adjusted.
Modifications have been made to the car's running gear that have an effect on the body height.
Vehicle level senders are re-taught in vehicles with damping control.
  Note
Before calibrating the front camera for driver assist systems, read out event memory and rectify faults as necessary.
Calibration of the front camera for driver assist systems must only be performed using VW/AUDI approved wheel alignment equipment!
Calibration of the driver assistant system's front camera is only permitted using the setting device -VAS 6430-!
Special tools and workshop equipment required
   
Setting device -VAS 6430-
Wheel alignment computer
→ Vehicle diagnostic tester
  Note
The front camera for driver assist systems -R242- must be correctly located in the holder.
The field of view of the camera must be clean and clear.
Before driving the vehicle onto the wheel alignment platform, make sure there is sufficient space between the midpoint of the hub of the front wheels and the setting device -VAS 6430-.
The distance between the setting device -VAS 6430- and the centre point of the hub of the front wheels must be 1500 mm ± 25 mm.
If available space is not adequate, move vehicle backwards onto alignment platform as required to achieve space required.
The calibration board must be positioned centrally on the setting device.
The event memory must be read before starting calibration. Any memory entries must be deleted.
–  Note testing preconditions for wheel alignment → Chapter.
–  Drive car onto wheel alignment platform.
–  Connect battery charger → Vehicle electrics; Rep. gr.27.
–  Connect → Vehicle diagnostic tester. (Route diagnostic cable through open window.)
  Note
During the calibration procedure, make sure that all the car doors remain closed and that the car's exterior lighting is switched off.
–  Move front wheels to straight-ahead position.
–  Select calibration run for front camera for driver assist systems -R242- on wheel alignment computer.
–  Mount quick-release clamps on all four wheels.
–  Mount measuring transducers on wheels.
–  Carry out wheel run-out compensation at rear wheels.
–  Bounce springs.
 

Calibrating front camera for driver assist systems

–  Measure standing height at all four wheels and note it.
  Note
Setting device -VAS 6430- is not allowed to be moved on alignment beam.
Wheel alignment platform must be in the lowermost levelled position for next work step.
 

Calibrating front camera for driver assist systems

–  Turn setting device -VAS 6430- upwards so that alignment beam is parallel to middle of measurement transducers on front wheels, in order to perform a correct measurement with distance measuring unit -1-.
1 -  Distance measuring unit with tape measure and socket pin
–  Position setting device -VAS 6430- at distance -a- of 1500 mm ± 25 mm from centre point of hub of front wheels to beam of setting device -VAS 6430-.
  Caution
Distance -a- of 1500 mm ± 25 mm must be measured on both sides of vehicle and setting device -VAS 6430- must then be aligned.
Distance -a- must be same on both sides of car.
 

Calibrating front camera for driver assist systems

–  Mount measurement transducer -1- of front wheels onto setting device -VAS 6430-.
 

Calibrating front camera for driver assist systems

–  Measure height value -a- between standing surface of setting device -VAS 6430- and wheel support surface on wheel alignment platform. Enter value in wheel alignment computer.
 

Calibrating front camera for driver assist systems

–  Unscrew clamping bolt -arrow-, place measuring bar -1- on floor.
 

Calibrating front camera for driver assist systems

–  Use crank -1- to set calibration panel -VAS 6430/4- to nominal height -2- indicated by wheel alignment computer and make a note.
 

Calibrating front camera for driver assist systems

When nominal height has been reached, measuring bar -1- must be moved upwards slightly and secured with clamping screw -arrow-.
 

Calibrating front camera for driver assist systems

–  Move setting device -VAS 6430- sideways -arrows B- until display on wheel alignment computer is within tolerance.
 

Calibrating front camera for driver assist systems

–  Screw down adjuster screws -2- and -3- slightly to secure setting device -VAS 6430- against rolling away.
 

Calibrating front camera for driver assist systems

–  Turn fine adjuster screw -1- until display on wheel alignment computer is within tolerance.
 

Calibrating front camera for driver assist systems

–  Use adjuster screw -1- to level spirit level -A-.
 

Calibrating front camera for driver assist systems

–  Use adjuster screws -2- and -3- to level spirit level -B-.
 

Calibrating front camera for driver assist systems

–  Unscrew clamping bolt -arrow-, place measuring bar -1- on floor.
 

Calibrating front camera for driver assist systems

–  Check nominal height -2- again and correct if necessary.
 

Calibrating front camera for driver assist systems

When nominal height has been reached, measuring bar -1- must be moved upwards slightly and secured with clamping screw -arrow-.
Concluding work is carried out via → Vehicle diagnostic tester.
–  Switch on ignition.
–  On → Vehicle diagnostic tester, select “Guided Fault Finding”.
