Driver Assistance Systems Front Camera, Calibrating
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
- Setting Device - Basic Set:VAS6430/1A
- John Bean V3D Aligner : VAS6331/1 for ADR/ACC adjustment
- Wheel Alignment Computer
Check if the Driver Assistance Systems Front Camera -R242- is seated correctly in the bracket.
Perform a visual inspection to determine 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 electronic 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 wheel alignment will be performed.
- The rear axle toe was adjusted.
- The vehicle suspension was changed, for example, changing from standard to Sport suspension.
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 without a Previous Axle Alignment
-- Select the front camera 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.
Calibration with a Previous Axle Alignment
-- Connect the battery charger. Refer to 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 doors.
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.
The procedure is described using a John Bean aligner : VAS6331 .
The procedure will differ if performed with other aligners. In this case, follow the instructions on the aligner screen.
-- 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 :VAS6430/1A 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 :VAS6430/1A , as shown.
- Measuring tape
The Setting :VAS6430/1A must not be moved on the calibration beam.
-- Place the :VAS6331/1 -1- for the ACC adjustment on the :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 :VAS6430/1A contact patch and the wheel contact surface as shown in the figure and enter it in the alignment computer.
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.
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-.
The bubble level adjustment -A- serves to balance the ground conditions.
-- Move the Setting :VAS6430/1A sideways in direction of -arrow B- until the display on the alignment computer is within the tolerance range.
-- Secure the setting :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.
-- Level the bubble level -A- using the adjusting screw -1-.
-- Level the bubble level -B- using the adjusting screws -2 and 3-.
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
- 01 - 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.
Next, determine the height of the body.
-- Enter the noted body height -a-.
