Driver Assistance Systems Front Camera, Calibrating

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 bracket for the Driver Assistance Systems Front Camera -R242- 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.

Procedure

The procedure is described on a John Bean V3D Aligner: VAS 6331  .

The procedure may vary if using other wheel alignment computers. In this case, follow the instructions on the wheel alignment computer screen.

• Observe the test requirements. Refer to TEST REQUIREMENTS .
• Measurement Preparations for Calibrating and Adjusting Driver Assist Systems. Refer to MEASUREMENT PREPARATIONS FOR CALIBRATING/ALIGNING THE DRIVER ASSIST SYSTEMS, QUICK ACCESS MODE .

-- Check if the Setting Device Basic Set:VAS 6430  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.

-- Drive the vehicle "straight" onto the alignment rack. Switch off the ignition when the vehicle has come to a stop.

-- Check the DTC memory for the Driver Assistance Systems Front Camera - R242-. Fix all displayed entries.

-- Move the wheels so that they are straight.

-- Install quick-action clamps on the wheels.

-- Mount the reflectors on the quick-action clamps.

-- Perform the 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:VAS 6430/1A  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:VAS 6430/1A  , as shown.

• The Setting Device - Basic Set:VAS 6430/1A  must not be moved on the calibration beam.

-- Place the Camera:VAS 6331/1  -1- for the ADR/ ACC adjustment on the Setting Device - Basic Set:VAS 6430  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:VAS 6430/1A  contact patch and the wheel contact surface as shown in the illustration and enter it in the alignment computer.

-- 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.

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

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

-- Move the Setting Device - Basic Set:VAS 6430/1A  at the sides in direction of -arrow B- until the display on the alignment computer is within the tolerance range.

-- Secure the Setting Device - Basic Set:VAS 6430/1A  by tightening the bolts -2 and 3- slightly. (This prevents the Setting Device Basic Set :VAS 6430  from rolling away).

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

Courtesy of AUDI

-- Level the bubble level -B- using the adjusting screw -2 and 3- in the scale.

Perform any Subsequent Work using the Vehicle Diagnostic Tester.

-- 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:

• Body
• 0001 - OBD-capable systems
• 00A5 - Driver Assistance Systems Front Camera - R242
• 00A5 - Driver Assistance Systems Front Camera functions
• 00A5 - Calibrate control module

-- 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.
