Driver Assistance Systems Front Camera, Calibrating
Special tools and workshop equipment required
- Wheel Alignment Computer approved by VW/Audi
- Vehicle Diagnostic Tester
- Wheel Alignment Computer - Camera: VAS701001/1
- Setting Device - Basic Set: VAS6430/1A
- Adapter VAS6430/9 : VAS6430/9 , only for surface mounted hoist with a dimension greater than 300 mm.
There are two choices for calibrating:
The "complete alignment"
This procedure should be selected for the following activities if a wheel alignment and calibration/adjustment should be performed.
- The rear axle toe was adjusted.
- The vehicle suspension was changed, for example changing from standard to sport suspension.
The "quick access"
This procedure should be selected for the following activities if only the calibration/adjustment will be performed.
- The test plan in the Vehicle Diagnostic Tester requires a readjustment.
- The Driver Assistance Systems Front Camera -R242- was removed and installed or replaced.
- The Driver Assistance Systems Front Camera -R242- bracket was removed and installed or replaced.
- The lens was replaced (window heating faulty).
- The inside of the black cut-out was cleaned.
- The wire for the Driver Assistance Systems Front Camera -R242- was replaced.
- The connector for the Driver Assistance Systems Front Camera -R242- was touched.
- The windshield was removed and installed or replaced.
- The standard vehicle height is reprogrammed.
TIP:
- Both procedures are programmed in the wheel alignment computer. The respective procedure is performed automatically. It is only necessary to select the appropriate program for the procedure that will be performed.
- If only the assistance systems front camera should be calibrated/adjusted, then the "quick access" mode must be selected on the wheel alignment computer.
- The procedure in the "quick access" mode is described in the following.
Procedure
As an example, the procedure is described for the Wheel Alignment Computer: VAS701 001 .
- Note the test requirements. Refer to TEST REQUIREMENTS .
- Follow the measurement preparations for calibrating/adjusting the driver assistance systems. Refer to MEASUREMENT PREPARATIONS .
-- Check if the Setting Device Basic Set: VAS6430/1 is in the center position and is locked.
-- Check if the Driver Assistance Systems Front Camera -R242- fits correctly in the bracket and the viewing range for the camera is not blocked.
-- Vehicles with rear axle steering: drive the vehicle "straight" onto the alignment rack. Switch off the ignition when the vehicle has come to a stop.
-- Steer the rear axle to the zero position. Refer to Rear Axle Steering .
- This is the only way to ensure that the rear axle steering is in the straight-ahead position.
-- Vehicle with air suspension: adjust to standard vehicle height and lock. Refer to Air Suspension .
-- Check the DTC memory for the Driver Assistance Systems Front Camera -R242-. Fix all displayed entries.
-- Position the front wheels so they are straight.
-- Install quick-action clamps on the wheels.
-- Attach the reflectors to the quick-action clamps.
-- Carry out wheel run-out compensation.
-- Select the button for the driver assistance systems front camera calibration procedure in the wheel alignment computer.
- The ACC Setting Device must not be moved on the calibration beam.
-- Make sure the calibration board is positioned in the center and is locked in place.
- Dimension -a- = dimension -b-.
-- Position the Setting Device Basic Set: VAS6430/1A at a distance of -a- 150 cm ± 2.5 cm from the center of the wheel hub on the front wheels to the beam on the Setting Device Basic Set : VAS6430/1A .
- Measuring tape
-- Place the Camera: VAS701001/1 -1- for the ACC adjustment on the Setting Device - Basic Set: VAS6430 on the right side and tighten.
- The alignment stand must be in the lowest level position for the next step.
-- Enter the height value -A- between the Setting Device Basic Set : VAS6430/1A contact patch and the wheel contact surface as shown in the illustration below and enter it in the alignment computer.
- Height of the calibration board: 1400 mm + height value -A-.
-- Loosen the bolt -arrow- and place the measuring bar -1- on the floor.
-- Adjust the calibration board to the specified height -2- according to the wheel alignment computer using the crank -1-.
TIP:
If the specified height was reached -2-, then the measuring bar must be pushed slightly upward and secured with the clamping screw.
- If in later procedures the height of the calibration board must be corrected, make sure the measuring bar is touching the ground when this is being done.
-- Level the bubble level -A- using the adjusting screw -1-.
TIP:
The bubble level adjustment -A- serves to balance the ground conditions.
-- Slide the Setting Device Basic Set: VAS6430 to the side -arrows B-, until the display in the wheel alignment computer is in the tolerance range.
-- Gently turn the screws -2- and -3- to secure the Setting Device Basic Set: VAS6430 from rolling away.
-- Turn the fine adjustment screw -1- until the display on the wheel alignment computer is within the tolerance range.
-- Level the bubble level -A- using the adjusting screw -1-.
-- Level the bubble level -B- using the adjusting screws -2 and 3-.
- Because small height changes can result after adjusting the bubble levels, the height of the calibration board must be checked again. Refer to DRIVER ASSISTANCE SYSTEMS FRONT CAMERA, CALIBRATING - .
-- Connect the Vehicle Diagnostic Tester.
-- Switch the ignition on.
-- Select and start the Diagnostic operating mode.
-- Select the Test plan tab.
-- Select the Select individual test button and select the following tree structure consecutively:

Continuation for All Vehicles
-- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.
Next, determine the height of the body.
-- Determine the body height -a- at all four wheels in the center of the wheel between the wheel contact surface and the lower edge of the fender or wheel housing.
