Adjustment Procedure Using ACC Setting Device (VAS 6190)

Adjustment Procedure using ACC Setting Device (VAS 6190)

Special tools, testers and auxiliary items required

• Vehicle Diagnosis, Testing and Information System (VAS 5051 A)

• Diagnostic Cable (VAS 5051/5A)

• ACC Adjustment Device (VAS 6190)

• Adjuster for ACC (VAS 6190/2)

• Wheel alignment computer

• ADC Test Fixture (VAS 6041)

• ADC Reflector Mirror (VAS 6041/1)

• The (VAS 6190) may have to be adapted for the adjustment procedure. Refer to => [ , Converting for Adjustment Procedure ] ACC Setting Device (VAS 6190), 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 (VAS 6190). The distance between the (VAS 6190) and the vehicle must be 120 cm +/- 5 cm.

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

• Before beginning the adjustment, check the Diagnostic Trouble Code (DTC) memory and correct any malfunctions present.

The adjustment procedure is described here with the (VAS 6190). However the (VAS 6041) and (VAS 6041/1) can also be used.

• 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 battery charger.

- 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.

• The (VAS 6190) must not be moved on the calibration beam.

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.






• 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.

- Load the (VAS 6190) with the weight - arrow - as shown in the illustration.






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






- 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 by sliding it sideways - arrows B - (VAS 6190) so that the laser beam is horizontally centered on the senor lens.






- Bring bubble levels - 2 - on (VAS 6190) into balance using adjustment screws - 1 -.






- 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.

• 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 (VAS 5051 B).

- Connect (VAS 5051/5A) to Data Link Connector (DLC).






- Turn (VAS 5051 A) on.

(VAS 5051 A) is ready to operate when it displays operating modes in button fields.

- Turn on ignition.

- Touch Guided Fault Finding.

- Select in succession:

• Brand

• Type

• Model year

• Version

• Engine Code

- Confirm data entered.

Wait until the (VAS 5051 A) 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".






The ACC adjustment is only accepted if "actuator diagnosis ended" is displayed in (VAS 5051/B).

- Turn ignition off.

- Disconnect (VAS 5051/5A) connector from DLC.

- Disconnect the battery charger.

- Install the air intake grille.
