Driver Assistance Systems Front Camera, Calibrating

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.

There are two options that can be selected for the calibration:

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 guide"

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 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 defogger faulty).
• The inner side of the opening on the glass 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.

TIP:

• Both procedures are programmed in the wheel alignment computer. The procedure is automatically performed. The corresponding program for the procedure to be performed must be selected.
• If only the calibration/adjustment of the driver assistance systems front camera should be performed, select the "quick start" mode on the wheel alignment computer.
• The procedure in the "quick start" mode is described in the information that follows.

Procedure 

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

• Note the test requirements. Refer to AXLE ALIGNMENT 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  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-. Correct all displayed entries.

-- Move the wheels so that they are in a straight-ahead position.

-- Install quick-action clamps on the wheels.

-- Attach the reflectors to 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.

• The Setting Device must not be moved on the calibration beam.

-- Check the calibration board to make sure it is centered and secured 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.

-- Determine height -A- between the contact surface on the Setting Device Basic Set: VAS6430  and the wheel contact surface as shown in the illustration and enter this value into the wheel alignment computer.

• Height of the calibration board: 1, 200mm + height value -A-.

-- Loosen the bolt -arrow- and position the measurement plate -1- on the ground.

-- Adjust the calibration board to the specified height -2- according to the wheel alignment computer using the crank -1-.

TIP:

Once the specified height -2- is reached, the measurement plate must be slid upward slightly and secured with the clamping screw.

• If the height of the calibration board is corrected at another point in the procedure, make sure that the measurement plate touches the floor at that point.

-- Bring the bubble level -A- into a level position using the adjusting screw -1-.

TIP:

The purpose of adjusting the level -A- is to compensate for uneven ground below the vehicle.

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

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

-- Bring the bubble level -A- into a level position using the adjusting screw -1-.

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

• Because the height may change slightly after adjusting the levels, check the height of the calibration board 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-. .

-- 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 - J1121
• 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.

The next step is to determine the height of the vehicle 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.
