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.

• Rear axle toe/chamber was adjusted.

The "quick access"

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

• The installation position of the Driver Assistance Systems Front Camera -R242- in the vehicle has changed.
• The connector for the Driver Assistance Systems Front Camera - R242- was touched.

TIP:

• 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 calibration/adjustment of the Driver Assistance Systems Front Camera -R242- should be performed, select the "quick start" mode on the wheel alignment computer.
• The procedure in the "quick access" mode is described in the following.

Special tools and workshop equipment required 

• Wheel Alignment Computer approved by VW/Audi
• Vehicle Diagnostic Tester
• Wheel Alignment Computer - Camera:VAS701001/1 
• Setting Device - Basic Set:VAS6430/1A

• Adapter VAS6430/9 :VAS6430/9  , only for surface mounted hoist with a dimension greater than 300 mm.

Procedure

As an example, the procedure is described for the Wheel Alignment Computer:VAS701001  .

• Note the test requirements. Refer to TEST REQUIREMENTS .
• Follow the measurement preparations for calibrating/adjusting the driver assistance systems. Refer to MEASUREMENT PREPARATIONS .

-- Check if the Setting Device Basic Set: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.

-- Vehicle with rear axle steering: drive the vehicle "straight" onto the alignment rack. Switch off the ignition when the vehicle has come to a stop.

-- Steer the rear axle to the zero position. Refer to Rear Axle Steering .

• This is the only way to ensure that the rear axle steering is in the straight-ahead position.

-- Vehicle with air suspension: adjust to standard vehicle height and lock. Refer to Air Suspension .

-- 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.

-- Attach the reflectors to 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: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 Setting Device Basic Set :VAS6430/1A  .

1. Measuring tape

-- Place the Camera:VAS701001/1  -1- for the ACC adjustment on the Setting Device - Basic Set:VAS6430  on the right side and tighten.

• For the next step, the alignment rack must be at the lowest level position.

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

• Height of the calibration board: 1, 400 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-. 

Courtesy of AUDI

TIP:

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-.

TIP:

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

-- Slide the Setting Device Basic Set:VAS6430/1  to the side in direction of -arrows B-, until the display in the wheel alignment computer is in the tolerance range.

Courtesy of AUDI

-- Secure the Setting Device - Basic Set:VAS6430  to prevent it from rolling by lightly tightening the screws -2 and 3-.

Courtesy of AUDI

-- Turn the fine adjustment screw -1- until the display on the wheel alignment computer is within the tolerance range.

Courtesy of AUDI

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

Courtesy of AUDI

-- Level the bubble level -B- using the adjusting screws -2 and 3-.

• 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 .

-- 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:

• Diagnostic-capable systems
• 00A5 - Driver Assistance Systems Control Module
• 00A5 - Driver Assistance Systems Control Module, functions
• 00A5 - Driver Assistance Systems Front Camera, Calibrating

-- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.

Next, determine the height of the body.

-- Determine the height of the vehicle body -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.
