Driver Assistance Systems Front Camera, Calibrating

Special tools and workshop equipment required 

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 "Quick Access"

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

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.

If only the 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 

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

-- Check if the :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.

-- 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.

-- Position the front wheels so they are straight.

-- Install quick-action clamps on the wheels.

-- Mount the reflectors on 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.

-- Make sure the calibration board is positioned in the center and is locked in place.

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.

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

-- 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  at the sides in direction of -arrow B- until the display on the alignment computer is within the tolerance range.

-- 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. Refer to DRIVER ASSISTANCE SYSTEMS FRONT CAMERA, CALIBRATING - Adjust the calibration board to the specified height -2- according to the wheel alignment computer using the crank -1-. .

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:

-- 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.
