-- Now using the laser beam -3- on the :VAS6430/1 , check if the laser beam contacts the sensor lens.

NOTE:

If the laser beam still meets the sensor lens at this step after adjusting the same individual toe values, the :VAS6430/1 is aligned correctly (positioned).

If the laser beam does not meet the sensor lens, the :VAS6430/1 must be aligned again.

-- Connect the Vehicle Diagnostic Tester

The Vehicle Diagnostic Tester is ready for operation when the operating modes are displayed.

-- Turn on the 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 the vehicle control module.

-- 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 :VAS6190/2 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".
