Night Vision Calibration Tool:VAS 6430/6
Adapter VAS 6430/9 :VAS 6430/9 , only for surface mounted hoist with a dimension greater than 300 mm.

If the vehicle has an adaptive cruise control and night vision system, then the night vision system must be adjusted/calibrated first and after that can the adaptive cruise control be adjusted.
Check the DTC memory and correct any malfunctions before beginning the calibration.
If the ACC Reflector Mirror - Audi:VAS 6430/3 is located on the calibration beam of the Setting Device - Basic Set:VAS 6430/1A or Setting Device Basic Set: VAS 6430 , it must be removed.

-- Check if the Night Vision System Camera -R212- fits correctly in the bracket and the viewing range for the camera is not blocked.

-- Make sure the protective window on the Night Vision System Camera -R212- is not chipped. Replace it if necessary. Refer to the appropriate Service Information. .

-- 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/adjusting:

The "quick access"

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

"No or incorrect basic setting/adaptation" is stored actively in the DTC memory.
The camera was removed or replaced.
The bumper or the radiator grille was removed or replaced.
The standard vehicle height was readapted.

The "complete alignment"

This procedure should be selected for the following activities if a calibration and a wheel alignment will be performed.

Adjustments were made to the rear axle
The vehicle suspension was changed, for example, from a standard to a sport suspension.

Both procedures can be selected in the wheel alignment computer of the respective manufacturer. The respective procedure is performed automatically. It is only necessary to select the appropriate program for the procedure that will be performed.

Calibration/adjustment 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.

-- Attach the sensor according to the wheel alignment computer instructions.

-- Select the infrared system calibration procedure in the wheel alignment computer.

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 for the battery support mode. Refer to BATTERY, CHARGING .

-- Position the wheels so that they are straight.

-- Connect the Vehicle Diagnostic Tester to the vehicle. (Guide the diagnostic cable through the door window.)

-- Turn off all vehicle exterior lamps.

-- Close all vehicle doors.

Calibrating with or without a previous axle alignment

-- Connect the Vehicle Diagnostic Tester to the vehicle. (Guide the diagnostic cable through the door window.)

-- Place the Night Vision Calibration Tool:VAS 6430/6 centered on the calibration beam from the Setting Device Basic Set:VAS 6430/1A .

-- Position the Night Vision Calibration Tool:VAS 6430/6 at distance -A- from the night vision system camera.

Distance -A- = 120 cm ± 2.5 cm, measured between the Night Vision Calibration Tool:VAS 6430/6 and the lens of the Night Vision System Camera -R212-.

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

For the following work steps, the hoist must be in the lowest position -A-.

-- Switch on the switch -B- for the Night Vision Calibration Tool:VAS 6430/6 .

TIP:

The Night Vision Calibration Tool:VAS 6430/6 performs an internal initialization after it is switched on. Both LEDs -C- blink at the same time and an acoustic tone will sound if the initialization is successful and was performed without any faults. After that, the Night Vision Calibration Tool:VAS 6430/6 will be in ready mode, which will be indicated by the green LED blinking slowly.

-- Check the bubble level and correct the adjustment if necessary.

-- Push the button -A- to activate the heating function.

An acoustic signal will sound when the heating function is activated. The heat-up phase has begun.

As soon as the specified temperature is reached, the green LED will stay on.

The heating elements switch off automatically after 20 minutes. An acoustic signal will sound approximately 1 minute before the heating elements switch off automatically.

Press the button -A- at any time to reset the timer back to 20 minutes. An short acoustic signal confirms that it has be reset.

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:
