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. If that is the problem, it should be corrected.
- The camera view field is fogged over.
If the camera lens is obstructed by a lot of dirt on the inside, then lens must be cleaned by hand. To do this, remove the control module and the lens, and clean the windshield using Cleaning Solution. Remove the control module and the lens. Refer to DRIVER ASSISTANCE SYSTEMS .
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 level control system sensor was readapted on vehicles with damping regulation.
Before calibrating the driver assistance systems front camera, check the 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.
The Driver Assistance Systems Front Camera -R242- must fit correctly in the bracket.
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.
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.
Check the DTC memory before calibrating. Erase any entries if necessary.
-- Follow the test requirements for an axle alignment. Refer to TEST REQUIREMENTS .
-- 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, 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 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, so that it is possible to correctly measure the distance measuring device -1-.
- Distance Measuring Device with Roller Tape Measure and Stud Bolt
-- Position the :VAS6430/1 at a distance -a- of 1500 mm ± 25 mm from the center of the wheel hub on the front wheels to the beam on the :VAS6430/1 .
- 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.
-- 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.
If the specified height was reached, then the measuring bar -1- must be pushed slightly forward and secured with the locking bolt -arrow-.
-- Slide the :VAS6430 to the side in direction of -arrows B-, until the display in the wheel alignment computer is in the tolerance range.
-- Gently turn the adjustment screws -2 and 3- to secure the :VAS6430/1 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.
If the specified height was reached, then the measuring bar -1- must be pushed slightly forward and secured with the locking bolt -arrow-.
Perform any subsequent work 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.
