Procedure 

-- Place vehicle on a solid, level surface.

-- Activate parking brake - vehicle must not move during measurement.

-- Place the steering wheel in the neutral position with the front wheels pointing straight ahead.

-- Connect the vehicle diagnostic tester using the Vehicle Diagnostic Tester.

-- Turn on the ignition.

-- Remove sticker with metal foil from bumper cover if necessary.

-- Secure three suitable wheel bolt adapters for the wheel bolts on each Calibration Tool - Wheel Center Mountings VAS 6350/1.

-- Insert the measuring paddle on both Calibration Tool - Wheel Center Mountings VAS 6350/1 and secure with lock nut.

-- Place the Calibration Tool - Wheel Center Mountings VAS 6350/1 onto the wheel bolts on both rear wheels.

• The wheel center mounting rotation center must be in the rotation center of the wheel.

-- Adjust the measuring paddle with aid of locking nuts so that they move freely just above the floor.

• The measuring paddles must move easily.
• The measuring paddles must be vertical.

-- Position the Calibration Tool VAS 6350 at distance -a- from rear wheels.

• Dimension -a- = 1700 mm.

-- Switch on the Calibration Tool - Spacing Laser VAS 6350/2 with the ON  button.

Display on the Calibration Tool - Spacing Laser VAS 6350/2:

• "- - - m"

-- For distance measurement, hold the Calibration Tool - Spacing Laser VAS 6350/2 -2- flush to the right stop bracket as illustrated.

• The Calibration Tool - Spacing Laser VAS 6350/2 must lie firmly against the catch bracket.

-- Make sure the "laser beam" for the distance measurement contacts the paddle on the lower enlarged part -1-.

If this is not the case, measure paddle height must be corrected using locking nuts on Calibration Tool - Wheel Center Mountings VAS 6350/1.

-- Briefly press the ON  button for distance measurement.

Display on the Calibration Tool - Spacing Laser VAS 6350/2:

• "1, 700 m" (specified value: 1, 700 ± 2 mm).

-- Repeat measurement procedure from left catch bracket to left rear wheel.

• The distance value must be the same on both sides.

If both measured values are not the same, adjust the Calibration Tool VAS 6350 accordingly.

Performing calibration 

Vehicle Diagnostic Tester is attached.

-- Choose operation mode Diagnosis  and start the diagnosis.

-- Select the tab test plan  .

-- Select select individual tests  and choose the following sequence.

• Body
• Electrical Equipment
• 01 - On Board Diagnostic (OBD) capable systems
• 3C - Lane change assistance control module - J769
• 3C - Lane change assistance control module, functions
• 3C - Calibration

The Vehicle Diagnostic Tester continues with the calibrating procedure from here on.

-- Secure the Calibration Tool - Lane Change Calibration Tool VAS 6350/4 at right rear of the Calibration Tool VAS 6350 mount.

• When installed correctly, vehicle electrical system voltage line must be connected at bottom left of calibration tool (as seen in direction of travel).
• Dimension -a- is measured from the upper edge of calibration tool to the floor.

-- Connect the Calibration Tool - Lane Change Calibration Tool VAS 6350/4 to the vehicle electrical system voltage.

-- Bring Calibration Device VAS 6350 into horizontal position by turning plastic base.

• Observe the bubble level (sight glass) on the Calibration Tool VAS 6350 -arrow-.

-- Switch on the Calibration Tool - Linear Laser VAS 6350/3 on the Calibration Tool VAS 6350.

-- Put on "Laser eye protection".

-- Align the Calibration Tool VAS 6350 so that the Calibration Tool - Linear Laser VAS 6350/3 strikes the center of the brand emblem on the rear lid.

-- Check the left and right distance between the catch bracket on the Calibration Tool VAS 6350 and measuring paddle -1- on wheel mountings again.

• Specified value: 1700 ± 2 mm

Calibration Procedure 

The following should not occur during the calibration procedure:

• No metal reflectors may be located within a 2 m radius of the calibration device (i.e. tool carts, metal cabinets).
• Vehicle doors must not be opened or closed.
• People should not sit in the vehicle.
• People must not go between the vehicle and the Calibration Tool - Lane Change Calibration Tool VAS 6350/4.

Procedure 

-- Switch the Calibration Tool - Lane Change Calibration Tool VAS 6350/4 on at the power switch -3-.

• The green LED -1- must light up.

-- Follow the instructions on the Vehicle Diagnostic Tester display.

During the course of the program, a request is made to switch the Calibration Tool - Lane Change Calibration Tool VAS 6350/4 from the right to the left side of the Calibration Tool VAS 6350.

-- Switch the Calibration Tool - Lane Change Calibration Tool VAS 6350/4 off and move device.

• When installed correctly, vehicle electrical system voltage line must be connected at bottom left of calibration tool (as seen in direction of travel).
• Dimension -a- is measured from the upper edge of calibration tool to the floor.
