Calibration Procedure With Or Without A Previous Axle Alignment

-- Remove the right front air intake grille. .

-- Remove all dirt on the sensor lens.

-- Position :VAS 6190 at a distance -A- of 120 cm +/- 5 cm from sensor lens to mirror surface.

WARNING:

Place a toolbox or container weighing approximately 5 to 7 kg on the :VAS 6190 before installing the measuring sensors and moving the mirror on the calibration beam.
If weight is not put on the :VAS 6190 , it could tip over when the mirror is moved and/or when the measuring sensors :VAS 6190 are installed.

-- Install the front wheel measuring sensors -1- on the :VAS 6190 .

-- Adjust vertical slits -4- on :VAS 6190 so that laser beam is vertically centered on sensor lens.

-- Adjust the same front axle individual toe settings using fine adjustment screw -3-.

-- The difference between individual toe values must be less than 6' or they must be the same.

-- Bring bubbles -2- on measurement sensor -1- into balance.

-- Now using laser beam -3- on :VAS 6190 , check whether laser beam contacts sensor lens.

NOTE:

If the laser beam still meets the sensor lens at this step after adjusting the same individual toe values, the :VAS 6190 is aligned correctly (positioned).

If the laser beam does not meet the sensor lens, :VAS 6190 alignment must be performed again.

-- Connect vehicle diagnostic tester.

-- Connect vehicle diagnostic tester to diagnostic connector.

-- Switch vehicle diagnostic tester on.

Vehicle diagnostic tester is ready to operate when it displays operating modes in button fields.

-- Switch on ignition.

-- Touch Guided Fault Finding .

-- Select in succession:

Brand
Type
Model year
Version
Engine Code

-- Confirm data entered.

Wait until the vehicle diagnostic tester has checked all available control modules in vehicle.

-- Press the go to button and select "function/component selection".

-- Select the corresponding program in "Guided Functions".

Now follow instructions on screen to perform adjustment.

-- Turn the :VAS 6190/2 in -direction of arrow A or B- and use the upper screw -2- and the lower screw -1- for precision adjustment in "Guided Fault Finding".

WARNING:

The ACC adjustment is only accepted if "actuator diagnosis ended" is displayed in vehicle diagnostic tester.

-- Switch ignition off.

-- Disconnect vehicle diagnostic tester connector from diagnostic connection.

-- Disconnect battery charger. Refer to GENERATOR .
