Infrared System, Calibrating, Q7 Before Product Improvement
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
- Wheel Alignment Computer
- Calibration Tool - Linear Laser: VAS 6350/3A (can be used from the Calibration Tool: VAS 6350 )
- Setting Device - Basic Set: VAS 6430/1 or Setting Device - Basic Set: VAS 6430/1A
- 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 NIGHT VISION SYSTEM .
-- 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 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 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 .
-- Move 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.)
-- Position the Night Vision Calibration Tool: VAS 6430/6 so that it is centered on the calibration beam on the Setting Device - Basic Set: VAS 6430/1 .
-- When sliding the Night Vision Calibration Tool: VAS 6430/6 onto the calibration beam, the opening -arrows- must fit around the nut or bolt -A-.
-- Fold up the right and left bracket -A-.
-- Tighten the right and left clamping screw -1- hand-tight.
-- Place the Setting Device Basic Set: VAS 6430/1A with the Night Vision Calibration Tool: VAS 6430/6 in front of the vehicle.
-- 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-.
-- Insert the Calibration Tool - Linear Laser: VAS 6350/3 -arrow- into the guide on the Night Vision Calibration Tool: VAS 6430/6 and secure it.
-- Switch on the Calibration Tool - Linear Laser: VAS 6350/3 . 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 Linear Laser: VAS 6350/3A can be switched off.
-- 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 : VAS 6430/1A sideways -arrow B- until the display on the alignment computer is within the tolerance range.
-- Secure the 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 precision adjustment screw -1- on the calibration beam until the display on the alignment computer is located within the tolerance range.
-- Balance the bubble level -A- using the adjusting screw -1-.
-- Balance the bubble level -B- using the adjusting screw -2-.
-- Switch the Calibration Tool - Linear Laser: VAS 6350/3 on again and check the specified height. Correct the height 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 Linear Laser: VAS 6350/3A can be switched off.
-- Connect the plug -A- for the Night Vision Calibration Tool: VAS 6430/6 to the socket.
-- 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.
-- Press the button -A- to activate the heat 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 Night Vision Calibration Tool: VAS 6430/6 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.
