• Adapter VAS 6430/9 :VAS 6430/9  , only for surface mounted hoist with a dimension greater than 300 mm.

Procedure

• For surface mounted hoist with a dimension greater than 300 mm the Setting Device - Basic Set:VAS 6430/1A  with the Adapter VAS 6430/9:VAS 6430/9  must be set higher.
• Check the DTC memory and correct any malfunctions before beginning the calibration.

-- 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.

-- Check of the visible area of the Driver Assistance Systems Front Camera -R242- is free.

-- "Activate vehicle lift mode" on equipment versions with air suspension. Refer to the appropriate Service Information or "Standard Vehicle Height, Initiating and Locking". Refer to STANDARD VEHICLE HEIGHT, INITIATING AND LOCKING .

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.

• The test plan in the Vehicle Diagnostic Tester requires a recalibration.
• 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.
• The standard vehicle height 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.

Calibrating without a previous axle alignment

• Switch off the ignition when the vehicle has come to a stop. This is the only way to ensure that the rear axle steering is in the straight-ahead position.

-- Select the front camera calibration procedure in the alignment computer.

-- Install quick-action clamps on the wheels.

-- Install the measuring sensors on the wheels.

-- Perform the wheel run-out compensation.

Calibrating with a previous axle alignment

• Switch off the ignition when the vehicle has come to a stop. This is the only way to ensure that the rear axle steering is in the straight-ahead position.

-- Connect the battery charger. Refer to BATTERY, CHARGING .

-- Position the wheels so that 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

-- 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- = 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 Setting Device - Basic Set:VAS 6430/1A  as shown in the illustration.

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

-- Mount the front wheel measuring sensors -1- to the Setting Device - Basic Set:VAS 6430/1A  .

• 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.

• 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-.

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 Setting Device - Basic Set:VAS 6430/1A  sideways -arrow B- until the display on the alignment computer is within the tolerance range.

-- Secure the setting device basic set 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).

-- 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-.

-- Balance the bubble level -B- using the adjusting screw -2-.

• 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, Q7 BEFORE PRODUCT IMPROVEMENT .

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
• Electrical system
• 01 - OBD-capable systems
• A5 - Driver Assistance Systems Front Camera -R242
• A5 - Driver Assistance Systems Front Camera Functions
• A5 - Control module calibrating

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

-- 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.
