Infrared System, Calibrating: Procedure

WARNING: This page is about a different car, the 2025 Audi SQ7 and 2025 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The procedure is described on a John Bean Wheel Alignment Computer John Bean V3D Aligner : VAS 6331 .

The procedure may vary if using other wheel alignment computers. In this case, follow the instructions on the wheel alignment computer screen.

Note the test requirements. Refer to 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 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-. Fix all displayed entries.

-- Move the wheels so that they are straight.

-- Install quick-action clamps on the wheels.

-- Attach the reflectors to the quick-action clamps.

-- Perform the wheel run-out compensation.

The ACC 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 :VAS 6430/6 so that it is centered on the calibration beam on the Setting Device - Basic Set :VAS 6430/1 .

-- 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 .

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.
