Driver Assistance Systems Front Camera, Calibrating
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 Setting Device Basic Set: VAS 6430/1 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.
Special tools and workshop equipment required
- Setting Device - Basic Set: VAS 6430/1A
- Wheel Alignment Computer
- Vehicle Diagnostic Tester
- 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, it is necessary to check if there is sufficient floor space in between the center of the wheel hub of the front wheels and the Setting Device Basic Set: VAS 6430 .
- The distance in between the Setting Device Basic Set: VAS 6430 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 TEST REQUIREMENTS .
-- Drive the vehicle onto the vehicle alignment platform.
-- Connect the battery charger. Refer to Battery, Charging .
-- Connect the =>. (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 straight.
-- Select the calibration procedure for the Driver Assistance Systems Front Camera -R242- 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 Setting Device Basic Set: VAS 6430 must not be moved on the calibration beam.
- The alignment stand must be in the lowest level position for the next step.
-- Rotate the Setting Device: VAS 6430/1 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 Setting Device Basic Set: VAS 6430 in distance -a- of 1500 mm ± 25 mm (59.06 ± 0.98 in.) from the center of the wheel hub from the front wheels to the beam of the Setting Device: VAS 6430 .
- Distance -a- 1, 500 mm ± 25 mm (59.06 ± 0.98 in.) must be measured on both side of the vehicle and then the Setting Device Basic Set: VAS 6430/1 must be aligned.
- Distance -a- must be the same on both sides of the vehicle.
-- Mount the front wheel measuring sensors -1- to the Setting Device Basic Set: VAS 6430/1 .
-- Determine the height value -a- between the Setting Device Basic Set: VAS 6430/1 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, 400 mm (55.12 in.) + height value -A-.
-- Loosen the clamping bolt -arrow- and place the measuring bar -1- on the floor.
-- Turn the crank -1- to adjust the Calibration Board For Lane Guard System: VAS 6430/4 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 Setting Device: VAS 6430 to the side in the 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 Setting Device Basic Set: VAS 6430/1 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.
-- 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.
