Driver Assistance Systems Front Camera, Calibrating

Calibration is Necessary if:

"No or incorrect basic setting/adaptation" is stored actively in the DTC memory.
The Driver Assistance Systems Front Camera -R242- was removed and installed or replaced,
The windshield is replaced or removed,
The rear axle toe was adjusted,
The vehicle suspension was changed, for example, changing from standard to sport suspension,
For vehicles with electronic damping, the level control system sensors were reprogrammed.

NOTE:

Before calibrating the Driver Assistance Systems Front Camera -R242-, check the DTC memory and correct any faults if necessary. To calibrate the Driver Assistance Systems Front Camera -R242-, the vehicle driving direction must be specified and serves as the reference position for the :VAS6430/1A . The Driver Assistance Systems Front Camera - R242- may only be calibrated using alignment equipment approved by VW/Audi. Only use the :VAS6430/1A to calibrate the lane assist.

Special tools and workshop equipment required

Vehicle Diagnostic Tester
Setting Device - Basic Set:VAS6430/1A
Wheel Alignment Computer

NOTE:

Check if the Driver Assistance Systems Front Camera -R242- is seated correctly in the bracket.

Perform a visual inspection to see if the camera visual area is free.

Check the DTC memory and correct any malfunctions before beginning the calibration.

There are Two Choices for Calibrating:

The "Quick Access"

This procedure should be selected for the following activities if only the calibration will be performed.

"No or incorrect basic setting/adaptation" is stored actively in the DTC memory.
the Driver Assistance Systems Front Camera -R242- was removed and installed or replaced,
the windshield is replaced or removed,
The control position on vehicles with air suspension was reprogrammed.

The "Complete Alignment"

This procedure should be selected for the following activities if a calibration and a wheel alignment will be performed.

The rear axle toe was adjusted.
The vehicle suspension was changed, for example, changing from standard to sport suspension.

NOTE:

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.

Calibration/Adjusting without a Previous Axle Alignment

-- Select the lane assist calibration procedure in the alignment computer.

-- Attach the quick-action clamps to all four wheels.

-- Mount the measurement sensor to the rear wheels.

-- Perform a wheel run-out compensation on the rear wheels.

Calibrating/Adjusting with a Previous Axle Alignment

-- Connect the battery charger. Refer to Battery Charger :VAS5095A .

-- Position the front wheels so they are straight.

-- Connect the Vehicle Diagnostic Tester to the vehicle and guide the diagnostic cable through the open window.

-- Turn off all vehicle exterior lamps.

-- Close all vehicle doors.

Calibration/Adjusting Procedure with or without a Previous Axle Alignment

-- Select calibration/adjustment on the wheel alignment computer.

-- Position the :VAS6430/1 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 :VAS6430/1 as shown in the illustration.

NOTE:

The :VAS6430/1A must not be moved on the calibration beam.

-- Mount the front wheel measuring sensors -1- to the :VAS6430/1A .

NOTE:

The alignment stand must be in the lowest level position for the next step.

-- Enter the height value -A- between the :VAS6430/1A contact patch and the wheel contact surface as shown in the illustration and enter it in the alignment computer.

-- 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-.

If the specified height was reached -2-, then the measuring bar must be pushed slightly upward and secured with the clamping screw.

NOTE:

If in later procedure the height of the calibration board must be corrected, make sure the measuring bar is touching the ground when this is being done.

-- Balance the bubble level -A- using the adjusting screw -1-.

The bubble level adjustment -A- serves to balance the ground conditions.

-- Move the :VAS6430/1A sideways in direction of -arrow B- until the display on the alignment computer is within the tolerance range.

-- Secure the :VAS6430/1 by tightening the bolts -2 and 3- slightly. (This prevents the :VAS6430 from rolling away).

Further Work Is Performed Using the Vehicle Diagnostic Tester in Guided Fault Finding.

-- Switch the ignition on.

-- Touch Guided Fault Finding on the screen.

-- Select in succession:

Brand
Type
Model year
Version
Engine Codes

-- Confirm the entered data.

Wait until the Vehicle Diagnostic Tester has checked all control modules in vehicle.

-- Press the go to button and select the "function/component selection".

-- Select the corresponding program in "Guided Functions".

Now follow the instructions on the screen to perform the calibration.

NOTE:

A step is performed in guided fault finding next to determine the body height.

-- 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.
