Calibration Procedure with or without a Previous Axle Alignment

-- Remove the right front air intake grille:

RS Model:

-- Remove the air guide to the coolant auxiliary cooler. Refer to AUXILIARY COOLER, REMOVING AND INSTALLING [For engine(s) CFSA] .

All Models:

Refer to FRONT BUMPER

-- Remove all dirt on the sensor lens.

-- Position :VAS6190 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 :VAS6190 before installing the measuring sensors and moving the mirror on the calibration beam.
If weight is not put on the :VAS6190 , it could tip over when the mirror is moved and/or when the measuring sensors are installed.

-- Load the :VAS6190 with the weight -arrow- as shown in the illustration.

-- Mount the front wheel measuring sensors -1- onto the :VAS6190 .

-- In area -A-, bring item -2- on rotary knob into alignment with marking on mirror (number 2 on rotary knob must face toward vehicle).

-- Now align the :VAS6190 by sliding it sideways in direction of -arrows B- so that the laser beam is horizontally centered on the senor lens.

-- Adjust vertical slits -4- on :VAS6190 so that laser beam is centered vertically 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 the laser beam -3- on the :VAS6190 , 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 :VAS6190 is aligned correctly (positioned).

If the laser beam does not meet the sensor lens, the :VAS6190 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 -arrows 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 confirmed when "output diagnostic test complete" appears in the Vehicle Diagnostic Tester.

-- Switch ignition off.

-- Disconnect the Vehicle Diagnostic Tester from the diagnostic connector.

-- Disconnect the battery charger. Refer to BATTERY .

RS Models:

-- Install the air guide to the coolant auxiliary cooler. Refer to AUXILIARY COOLER, REMOVING AND INSTALLING [For engine(s) CFSA] .

-- Install the front bumper cover. Refer to FRONT BUMPER .

All Models:

-- Install the air intake grille. Refer to FRONT BUMPER .
