Night Vision System, Calibrating, AUDI Q7
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
- Wheel Alignment Computer
- Calibration Tool - Linear Laser: VAS6350/3A (can be used from the Calibration Tool: VAS6350 )
- 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.
- 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 : VAS6430/3 is located on the calibration beam of the : VAS6430/1A or : VAS6430 , 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 NIGHT VISION SYSTEM CAMERA -R212-, REMOVING AND INSTALLING .
-- Check of the visible area of the Driver Assistance Systems Front Camera -R242- is free.
-- "Activate wheel change mode" on equipment versions with air suspension. Refer to Owner's Manual 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 "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 suspension system on the vehicle was altered
- 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 front wheels so 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 : VAS6430/6 centered on the calibration beam from the : VAS6430/1A .
-- The opening -arrows- must surround the nut and bolt -A- when the : VAS6430/6 is pushed onto the calibration beam.
-- Fold up the right and left bracket -A-.
-- Tighten the right and left clamping screw -1- hand-tight.
-- Place the : VAS6430/1A with the : VAS6430/6 in front of the vehicle.
-- Position the : VAS6430/6 in distance -A- to the night vision camera.
- Distance -A- = 120 cm ± 2.5 cm, measured between the : VAS6430/6 and the lens on 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-.
-- Place the : VAS6350/3A -arrow- in the guide of the : VAS6430/6 and tighten.
-- Switch on the : VAS6350/3 . A laser beam is beamed on the vehicle.
-- Turn the lever on the back of the calibration board to align the laser beam so that it is in the center of the camera lens in the horizontal position.
The specified height is now reached and the : VAS6350/3A can be switched off.
-- Level the bubble level -A- using the adjusting screw -1-.
The bubble level adjustment -A- serves to balance the ground conditions.
-- Move the : VAS6430 sideways -arrow B- until the display on the alignment computer is within the tolerance range.
-- Secure the : VAS6430 by tightening the bolts -2- and -3- slightly. (This prevents the : VAS6430 from rolling away).
-- Turn the precision adjustment screw -1- on the calibration beam until the display on the alignment computer is located within the tolerance range.
-- Level the bubble level -A- using the adjusting screw -1-.
-- Balance the bubble level -B- using the adjusting screw -2-.
-- Turn the : VAS6350/3 back on and check the specified height and correct if necessary. A laser beam is beamed on the vehicle.
-- Turn the lever on the back of the calibration board to align the laser beam so that it is in the center of the camera lens in the horizontal position.
The specified height is now reached and the : VAS6350/3A can be switched off.
-- Connect the connector -A- for the : VAS6430/6 to the power supply.
-- Turn on the switch -B- for the : VAS6430/6 .
TIP:
After switching on the : VAS6430/6 an inner initialization takes place. 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. Then the : VAS6430/6 is in the ready mode. The green LED will blink 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:
- Body
- Electrical system
- 01 - OBD-capable systems
- 84 - Night Vision System Control Module
- 84 - Night Vision System Control Module Functions
- 84 - Control Module, Calibrating
-- Start the selected program and follow the instructions on the Vehicle Diagnostic Tester display.
Turn the adjusting screw with a Phillips screwdriver to mechanically adjust the Night Vision System Camera -R212- around its roller axle.
-- Insert the Phillips screwdriver -arrow- and make the adjustment according to the specification using the Vehicle Diagnostic Tester.
- Make sure there is no one or nothing between the Night Vision System Camera -R212- and the : VAS6430/6 while making the adjustment.
Adjusting the pitch-yaw angle of the Night Vision System Camera -R212- takes place completely electronically via the Vehicle Diagnostic Tester.
