Driver Assistance Systems Front Camera, Calibrating
Special tools and workshop equipment required
- Setting Device - Basic Set: VAS6430/1A
- Wheel Alignment Computer
- Vehicle Diagnostic Tester
If the camera can no longer recognize the lane markings due to poor visibility, this could be caused by:
- The camera field of view is dirty or icy. In this case, the contamination or icing must be removed.
- The camera view field is fogged over.
If heavy contamination at the inside of the windshield in the viewer of the camera is present, then the viewer of the camera must be cleaned by hand. For this, the control module and the lens must be removed and the windshield has to be cleaned with cleaning solution. Removing the control module and the lens Refer to the appropriate Service Information
The correct calibration is a basic requirement for the correct function of the front camera.
It is necessary to calibrate the front camera anew for the following reasons:
- "No or incorrect basic setting/adaptation" is stored in the event memory.
- The front camera has been 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 level control system sensor was readapted on vehicles with damping regulation.
Before calibrating the driver assistance systems front camera, the DTC memory must be checked and any faults corrected if necessary.
Calibration of the driver assistance systems front camera may only be performed with a VW/AUDI approved alignment tester!
Only the : VAS6430/1 may be used to calibrate the driver assistance systems front camera.
The calibration target must be illuminated sufficiently and evenly.
Selective illumination by another light source must be avoided.
The front camera must be correctly seated in the bracket.
The camera viewing range must be clean and unobstructed.
Before the vehicle is driven onto the wheel alignment platform, necessarily check if there is sufficient floor space in between the center of the wheel hub of the front wheels and the : VAS6430 .
The distance in between the : VAS6430 and the center of the wheel hub of the front wheels must be 1500 mm ± 25 mm.
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.
The DTC memory must be checked before starting the calibration. If applicable, any DTC memory entries must be corrected.
-- Pay attention to the test requirements for the axle alignment. Refer to the appropriate Service Information .
-- Drive the vehicle onto the vehicle alignment platform.
-- Connect the battery charger. Refer to Battery, Charging .
-- Connect the Vehicle Diagnostic Tester. (Guide the diagnostic cable through the open window.)
During the calibration procedure pay attention that all vehicle doors remain closed and the vehicle exterior lamps are off.
-- Move the wheels so that they are in a straight-ahead position.
-- Select the calibration procedure for the driver assistance systems front camera -R 242- 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 on the rear wheels.
-- Bounce the vehicle.
-- Measure and record the height at all four wheels.
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, to correctly perform the measurement using the distance measuring device -1-.
- Distance Measuring Device with Roller Tape Measure and Stud Bolt
-- Position the : VAS6430 in distance -a- of 1500 mm ± 25 mm from the center of the wheel hub from the front wheels to the beam of the : VAS6430 .
Distance -a- 1, 500 mm ± 25 mm 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.
-- Mount the front wheel measuring sensors -1- to the : VAS6430/1 .
-- Determine the height value -a- between the : VAS6430/1 contact surface and the wheel contact surface on the vehicle alignment platform. Enter the determined value in the wheel alignment computer.
- Height of the calibration board: 1, 200 mm + height value -A-.
-- Loosen the clamping bolt -arrow- and place the measuring bar -1- on the floor.
-- Turn the crank -1- to adjust the : VAS6430/4 to the height specification -2- and then make a note of it.
When the Specified Height Has Been Reached, Slide the Measurement Beam -1- Slightly Upward and Secure it with the Clamping Screw -arrow-
-- Slide the : VAS6430 to the side in direction of -arrow-, until the display in the wheel alignment computer is in the tolerance range.
-- By gently turning the adjustment screws -1 and 2-, the : VAS6430/1 is secured from rolling away.
-- Turn the fine adjustment screw -1- until the display on the wheel alignment computer is within the tolerance range.
-- Balance the bubble level -A- using the adjusting screw -1-.
-- Level the bubble level -B- using the adjusting screws -2 and 3-.
-- Loosen the clamping bolt -arrow- and place the measuring bar -1- on the floor.
-- Check the specified height -2- one more time and adjust if necessary.
When the Specified Height Has Been Reached, Slide the Measurement Beam -1- Slightly Upward and Secure it with the Clamping Screw -arrow-
Additional Procedures are Performed using the Vehicle Diagnostic Tester.
-- Switch the ignition on.
-- Select the "Guided Fault Finding" using the Vehicle Diagnostic Tester.
Follow the instructions on the screen to perform the calibration.
Next, in guided fault finding, determine the height of the body.
-- Enter the recorded ride heights.
