- Insert the measuring paddle on both Calibration Tool - Wheel Center Mountings -VAS6350/1- and secure with lock nut.

- Place the Calibration Tool - Wheel Center Mountings -VAS6350/1- onto the wheel bolts on both rear wheels.

• The wheel center sensor rotation center must be in wheel rotation center.

  Note

Place the Calibration Tool - Wheel Center Mountings -VAS6350/1- on wheels so that "anti-theft wheel bolts" are not connected with wheel center mounting.

- 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 -VAS6350- at distance -a- from rear wheels.

• Dimension -a- = 1700 mm.

- Switch on the Calibration Tool - Spacing Laser -VAS6350/2- with the ON button.

Display on the Calibration Tool - Spacing Laser -VAS6350/2-:

• "- - - m"

  Note

The laser is switched on at same time.

- For distance measurement, hold the Calibration Tool - Spacing Laser -VAS6350/2--2- flush to the right stop bracket as illustrated.

• The Calibration Tool - Spacing Laser -VAS6350/2- 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 -VAS6350/1-.

- Briefly press the ON button for distance measurement.

Display on the Calibration Tool - Spacing Laser -VAS6350/2-:

• "1.700 m" (specified value: 1700 +- 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 -VAS6350- 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 - 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.

  Note

• The following information clarifies which version of the lane change assistance is installed (version SWA1.7).
• This information for adjusting the calibration device is important for later steps in the procedure to avoid malfunctions.

- Secure the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- at right rear of the Calibration Tool -VAS6350- mount.

• When installed correctly, vehicle electrical system voltage line must be connected at bottom left of calibration device (as seen in direction of travel).

Dimension -a- is measured from the upper edge of calibration device to the floor.

- The indicator on the base of the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- must align with adjustment dimension on the measuring scale -1- on measuring field -arrow-.

- Connect the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- to the vehicle electrical system voltage.

- Bring Calibration Device -VAS6350- into horizontal position by turning plastic base.

• Observe the bubble level (sight glass) on the Calibration Tool -VAS6350--arrow-.

- Switch on the Calibration Tool - Linear Laser -VAS6350/3- on the Calibration Tool -VAS6350-.

- Put on "Laser eye protection".

- Align the Calibration Tool -VAS6350- so that the Calibration Tool - Linear Laser -VAS6350/3- 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 -VAS6350- 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 two m radius of the calibration device (for example, 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 -VAS6350/4-.

Procedure

- Switch on the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- at the power switch -3-.

• The green LED -1- must light up.

  Note

If the red LED -2- illuminates: Check the Calibration Tool - Lane Change Calibration Tool -VAS6350/4-.

- Follow the instructions on the Vehicle Diagnostic Tester display.

During the course of the program, a request is made to switch the calibration unit for lane change assist -VAS6350/4- from the right to the left side of the Calibration Tool -VAS6350-.

- Switch the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- off and move device.

• When installed correctly, vehicle electrical system voltage line must be connected at bottom left of calibration device (as seen in direction of travel).

Dimension -a- is measured from the upper edge of calibration device to the floor.

- The indicator on the base of the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- must align with adjustment dimension on the measuring scale -1- on measuring field -arrow-.

- Switch on the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- at the power switch -3-.

• The green LED -1- must light up.

- Follow the instructions on the Vehicle Diagnostic Tester display.

- After calibrating the lane change assistance successfully, end "calibration", switch off the ignition and disconnect the diagnostic connector.
