Night Vision System, Calibrating

Special tools and workshop equipment required 

• Wheel Alignment Computer approved by VW/Audi
• Vehicle Diagnostic Tester
• Calibration Tool - Linear Laser: VAS6350/3A 
• Setting Device - Basic Set: VAS6430/1  or Setting Device - Basic Set: VAS6430/1A 
• Night Vision Calibration Tool: VAS6430/6 
• 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 calibration.
• The Night Vision System Camera -R212- was removed and installed or replaced.
• The bumper or radiator grille was removed and installed or replaced.

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 night vision system calibration/adjustment 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 Night Vision System Camera -R212- fits correctly in the bracket and the viewing range for the camera is not blocked.

-- Check if the protective window on the Night Vision System Camera -R212- is damaged by a stone impact and replace if necessary. Refer to Removing - Protective Window, Removing .

-- 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 Night Vision System Camera -R212-. 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.

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

-- Select the button for the night vision system camera calibration procedure on the wheel alignment computer.

-- Position the Night Vision Calibration Tool: VAS6430/6  so that it is centered on the calibration beam on the Setting Device - Basic Set: VAS6430/1  .

-- When sliding the Night Vision Calibration Tool: VAS6430/6  onto the calibration beam, the opening -arrows- must fit around the nut or bolt -A-.

-- Fold open the left and right bracket -A-.

-- Tighten the right and left clamping screws -1- by hand.

-- Position the Setting Device - Basic Set: VAS6430/1  with the Night Vision Calibration Tool: VAS6430/6  in front of the vehicle.

-- Position the Night Vision Calibration Tool: VAS6430/6  at distance -A- from the night vision system camera.

• Distance -A- = 120 cm ± 2.5 cm, measured between the Night Vision Calibration Tool: VAS6430/6  and the lens of the Night Vision System Camera -R212-.

-- Attach the sensor for the front wheels to the calibration beam.

• For the next step, the hoist must be located in the lowest level position -A-.

-- Insert the Calibration Tool - Linear Laser: VAS6350/3  -arrow- into the guide on the Night Vision Calibration Tool: VAS6430/6  and secure it.

-- Switch on the Calibration Tool - Linear Laser: VAS6350/3  .

-- Align the laser beam by turning the crank on the back of the calibration board until the beam strikes the horizontal center of the camera lens.

TIP:

This will achieve the specified height and the Calibration Tool - Linear Laser: VAS6350/3  can be switched off.

-- 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 -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-.

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

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

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

-- Switch the Calibration Tool - Linear Laser: VAS6350/3  on again and check the specified height. Correct the height if necessary.

-- Align the laser beam by turning the crank on the back of the calibration board until the beam strikes the horizontal center of the camera lens.

TIP:

This will achieve the specified height and the Calibration Tool - Linear Laser: VAS6350/3  can be switched off.

-- Connect the plug -A- for the Night Vision Calibration Tool: VAS6430/6  to the socket.

-- Switch on the switch -B- for the Night Vision Calibration Tool: VAS6430/6  .

• The Night Vision Calibration Tool: VAS6430/6  performs an internal initialization after it is switched on. If it completes successfully with no errors, both LEDs -C- will blink at the same time while an indicator tone sounds. After that, the Night Vision Calibration Tool: VAS6430/6  will be in ready mode, which will be indicated by the green LED blinking slowly.
• Check the bubble levels and adjust if needed.

-- Press the button -A- to activate the heat function.

• An audio signal will indicate that the heat function has been activated. The warm-up phase for the heating element has begun.
• Once the specified temperature is reached, the green LED will stay on.
• The heating elements will switch off automatically after approximately 20 minutes. A intermittent audio signal will sound approximately one minute before the automatic shut-off.
• The shut-off timer can be reset to 20 minutes at any time by pressing the button -A-. An audio signal confirms when the timer is reset.

-- 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
• 0084 - Night Vision System Control Module
• 0084 - Night Vision System Control Module functions
• 0084 - Control module, calibrating

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