ADJUSTMENT PROCEDURE WITH Setting Device - Basic Set:VAS 6430 FROM MY 2017: Procedure

The procedure is described for a John Bean V3D Aligner :VAS6331  .

• Check if the adaptive cruise control (ACC) radar sensor is seated correctly in the bracket.
• Before beginning the adjustment, read out the DTC memory and correct any malfunctions present.
• The bolts on the ACC radar sensor are only for the first basic setting of the sensor.

There are two options for adjusting the adaptive cruise control sensors:

The "quick access"

Select this procedure for the following operations if only the adjustment should be performed.

• The Distance Regulation Control Module -J428- was removed and installed.
• The front lock carrier was loosened or adjusted.
• The front impact member was loosened or adjusted.
• There is damage on the front impact member or lock carrier.
• The adjustment angle is grater and -0.8° to +0.8°.

The "complete alignment"

Select this procedure for the following operations if the adjustment and a wheel alignment should be performed.

• The rear axle toe was adjusted.
• The vehicle suspension was changed, for example changing from standard to sport suspension.

Do not perform the steps under "Calibration procedure without a previous axle alignment" if an axle alignment has already been performed.

• Preparation work for calibrating and adjusting driver assist systems. Refer to PREPARATION WORK FOR CALIBRATING DRIVER ASSISTANCE SYSTEMS .
• The ACC Setting Device must not be moved on the calibration beam.

Calibration Procedure without Previous Axle Alignment: 

-- Switch off the ignition.

-- Connect the battery charger for the battery support mode. Refer to BATTERY .

-- Position the front wheels so they are straight.

-- Connect the Vehicle Diagnostic Tester to the vehicle and guide the diagnostic cable through the open window.

-- Turn off all vehicle exterior lamps.

-- Close all vehicle doors.

-- Mount the quick clamps to the rear wheels.

-- Mount the measurement sensor to the rear wheels.

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

Calibration Procedure with or without Previous Axle Alignment:

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

-- Install the :VAS6430/10  centered on the calibration beam.

-- Remove any dirt from the sensor lens.

-- Position the :VAS6430/1A  using the :VAS6430/10  -1- centered and parallel at the distance -a- to the sensor lens in the radiator grille.

• Dimension -a- = 120 ± 2.5 cm

-- Place the Camera :VAS6331/1  -1- for the ACC adjustment on the :VAS6430  on the right side and tighten.

-- Level the bubble level -B- using the adjusting screw -2-.

-- Adjust the height of the reflector mirror with the crank -arrow-, so that the laser beam is in the vertical center of the sensor lens.

-- If necessary, reposition the reflector mirror at the side on the calibration beam, until the laser beam is in the horizontal center of the sensor lens.

-- Turn the fine adjustment screw -4- until the display on the wheel alignment computer is within the tolerance range.

-- Using the laser beam on the reflector mirror, check again if the laser beam contacts the center of the sensor lens. If necessary align the reflector mirror again.

Perform any Subsequent work using the Vehicle Diagnostic Tester:

The Vehicle Diagnostic Tester is connected.

-- Select the Diagnostic  mode and start the diagnosis.

-- Select the Test plan  tab.

-- Select the Select individual test  button and select the following tree structure consecutively:

• Body
• Electrical system
• 01 - OBD-capable systems
• 13 - Distance regulation -J428
• 13 - Distance Regulation Control Module, functions
• 13 - Adjustment

Follow the instructions on the screen to perform the adjustment.
