There are two choices for calibrating:

The "complete alignment"

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

Rear axle toe/chamber was adjusted.

The "quick access"

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

The installation position of the Night Vision System Camera -R212- in the vehicle has changed.

TIP:

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

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 access" mode is described in the following.

Procedure

NOTE:

The procedure is described on a John Bean Wheel Alignment Computer: VAS6331 .

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 -R212- calibration procedure on the wheel alignment computer.

-- Place the Night Vision Calibration Tool:VAS6430/6 centered on the calibration beam from the Setting Device Basic Set:VAS6430/1A .

-- The opening -arrows- must surround the nut and bolt -A- when the Night Vision Calibration Tool:VAS6430/6 is pushed onto the calibration beam.

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

-- 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 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-.

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

After switching on the Night Vision Calibration Tool: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 Night Vision Calibration Tool:VAS6430/6 is in the ready mode. The green LED will blink 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.

-- Connect the Vehicle Diagnostic Tester.
