Special Tools And Workshop Equipment Required

Vehicle Diagnostic Tester
Vehicle Diagnosis System - Updated Cable - 3m VAS5051/5A
Setting Device Basic Set VAS6430/1
ACC Adjuster VAS6190/2
Wheel Alignment Computer

NOTE:

The Setting Device Basic Set VAS6430/1 may have to be adapted for the adjustment procedure, refer to Setting Device Basic Set VAS6430/1 CONVERTING FOR ADJUSTMENT PROCEDURE .

Before driving the vehicle onto the alignment stand, check whether there is a sufficiently large space between the vehicle and the Setting Device Basic Set VAS6430/1. The distance between the Setting Device Basic Set VAS6430/1 and the vehicle must be 120 cm ± 5 cm.

If there is not enough space, drive vehicle the backward on the alignment stand in order to be able to use the space.

Before beginning the adjustment, check the DTC memory and correct any malfunctions present.

The adjustment procedure is described here using the Setting Device Basic Set VAS6430/1. The ADC Adjustment Fixture VAS6041 and the ADC Adjustment Fixture VAS6041/1A can also be used.

NOTE:

If there was a previous axle alignment, the steps under "Calibration procedure without a previous axle alignment" should not performed.

Calibration procedure without a previous axle alignment

-- Connect the battery charger, refer to BATTERY, CHARGING .

-- Select the ACC calibration button on the alignment computer.

-- Install quick clamps on the rear wheels.

-- Install measuring sensors on the rear wheels.

-- Perform a rim run-out compensation on the rear wheels.

NOTE:

The Setting Device Basic Set VAS6430/1 must not be moved on the calibration beam.

Calibration procedure with or without a previous axle alignment

-- Release the bracket -1- and remove the air intake grille -2-.

WARNING:

Place a toolbox or container weighing approximately 5 to 7 kg on the Setting Device Basic Set VAS6430/1 before installing the measuring sensors and moving the mirror on the calibration beam.
If weight is not put on the Setting Device Basic Set VAS6430/1, the Setting Device Basic Set VAS6430/1 could tip over when the mirror is moved and/or when the measuring sensors are installed.

-- Load the Setting Device Basic Set VAS6430/1 with the weight -arrow- as shown in the illustration.

-- Adjust vertical slits -4- on Setting Device Basic Set VAS6430/1 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 Setting Device Basic Set 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 Setting Device Basic Set VAS6430/1 is aligned correctly (positioned).

If the laser beam does not meet the sensor lens, the Setting Device Basic Set VAS6430/1 must be aligned again.

-- Connect the Vehicle Diagnostic Tester:

-- Connect the connector of the Vehicle Diagnosis System - Updated Cable - 3m VAS5051/5A to the diagnostic connection.

-- Switch on the Vehicle Diagnostic Tester.

The Vehicle Diagnostic Tester is ready to operate when it displays operating modes in button fields.

-- 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 check all the control modules in the 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 ACC Adjuster VAS6190/2 in direction of -arrow A or B- and use the lower screw -2- and the upper screw -1- for precision adjustment in "Guided Fault Finding ".
