-- Place the front wheels in a straight-ahead position - steering wheel in 0 position.
-- Connect the vehicle diagnostic tester using the Vehicle Diagnostic Tester.
If a malfunction message appears in the display, refer to the Vehicle Diagnostic Tester Operating Instructions.
-- Turn on the ignition.
Risk of unintentional engine start and poisonous gas in closed spaces when working on vehicles with ignition turned on or on vehicles that are ready to drive. Risk of limbs and/or clothing being pinched and pulled.
Perform the following items before turning on the ignition:
- Put the selector lever into position P.
- Activate the parking brake.
- Turn off the ignition.
- Open the hood.
- Connect the charging unit for example, Battery ChargerVAS 5095A to the battery jump start terminal for the 12V vehicle electrical system.
- Turn on the ignition
-- Remove the sticker with metal foil from the bumper cover if necessary.
-- Secure three suitable wheel bolt adapters for the wheel bolts on each Calibration Tool - Wheel Center Mountings -VAS6350/1-.
-- Insert the measuring paddle on both Calibration Tool - Wheel Center Mountings -VAS6350/1- and secure with lock nut.
-- Place the Wheel Center Mountings -VAS6350/1- onto the wheel bolts on both rear wheels.
- The wheel center sensor rotation center must be in the rotation center of the wheel.
Place Wheel Center Sensor -VAS6350/1- on wheels so that "anti-theft wheel bolts" are not connected with wheel center sensor.
-- Adjust the measuring paddle with the aid of the lock 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"
The laser is switched on at same time.
-- For distance measurement, hold the Calibration Tool - Spacing Laser VAS6350/2 -2- flush to the left catch bracket as shown.
- 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 Wheel Center Mounting -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 the measurement procedure from the right catch bracket to the right 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.
-- Select the Diagnostic mode and start the diagnostics.
-- 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.
The following information clarifies which version of the lane change assistance is installed (version SWA1.7).
This information for adjusting the calibration tool is important for later steps in the procedure to avoid malfunctions.
-- Secure the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- at left rear of the Calibration Tool VAS6350 mount.
- When installed correctly, vehicle electrical system voltage line must be connected at bottom left of the calibration device (as seen in direction of travel).

Procedure
-- Switch on the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- at the power switch -3-.
- The green LED -1- must light up.
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 program sequence, a request is made to switch the Calibration Tool - Lane Change Calibration Tool -VAS6350/4- from the left to the right 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 the calibration device (as seen in direction of travel).
