Driver Assistance Systems Front Camera, Calibrating

Special Tools And Workshop Equipment Required

Setting Device Basic Set - VAS6430/1-
Wheel Alignment Computer

NOTE:

Check if the Driver Assistance Systems Front Camera - R242- is seated in the bracket correctly.
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,
on vehicles with electronically-controlled damping (Audi magnetic ride), the control position was reprogrammed.

The "Complete Alignment"

This procedure should be selected for the following activities if a calibration and a suspension adjustment 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 into the axle alignment computer. The respective procedure is performed automatically. It is only necessary to select the appropriate program for the procedure that will be performed.

Note The Preparation Work For Calibrating Driver Assistance Systems. Refer To Preparation Work for Calibrating Driver Assistance System s

Calibrating Without A Previous Axle Alignment:

Select the front camera calibration procedure in the alignment computer.
Install the quick clamps on all four wheels.
Mount the measurement sensor to the rear wheels.
Perform a wheel run-out compensation and the rear wheels.

Calibrating With A Previous Axle Alignment:

Connect the battery charger. Refer to Electrical Equipment (Battery, Charging).
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 door.

Calibrating/Adjusting Procedure With Or Without A Previous Axle Alignment:

Determine and then note 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.
Select the front camera calibration procedure in the alignment computer.
Make sure the calibration board is positioned in the center and is locked in place.

Dimension a = b

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.

Measuring tape

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

Place the Camera -VAS6331/1- -item 1- for the ACC adjustment on the -VAS6430- on the right side and tighten.
NOTE: The alignment stand must be in the lowest level position for the next step.
Enter the height value -A- between the -VAS6430/1- contact patch and the wheel contact surface as shown in the illustration and enter it in the alignment computer.

NOTE:

Height calibration board for all Audi SUV models: 1400 mm + height value -A-.
Height calibration board for all Audi non-SUV models: 1200 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-.

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 procedures 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 sideways -arrow B- until the display on the alignment computer is within the tolerance range.
Secure the -VAS6430/1A- by tightening the bolts -2 and 3- slightly. (This prevents the -VAS6430- 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 screw -2-.

NOTE: Because small height changes can result after adjusting the bubble levels, the height of the calibration board must be checked again. .

Perform any subsequent work using the Vehicle Diagnostic Tester:

The Vehicle Diagnostic Tester is connected.

Select the Diagnostic mode and start the diagnosis.
Select the Test plan tab.
Select the Select individual test button and select the following tree structure consecutively:

Body
Electrical system
OBD-capable systems
A5 - Driver Assistance Systems Front Camera - R242
A5 - Driver Assistance Systems Front Camera, functions
A5 - Control module calibrating

From here, the Vehicle Diagnostic Tester advances the calibration procedure forward.

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

NOTE: Next, determine the height of the body.

Enter the noted body height -a-.
