Lane Change Assistance, Calibrating, Stationary Calibration

Calibration/adjustment must be performed if:

• "No or incorrect basic setting/adaptation" is actively entered in the DTC memory of the Lane Change Assistance Control Module -J769- / Lane Change Assistance Control Module 2 -J770-.
• The Lane Change Assistance Control Module -J769- and/or Lane Change Assistance Control Module 2 -J770- has/have been removed and installed or replaced.
• The rear bumper was removed and installed.
• The rear bumper cover has been damaged or replaced.

Preliminary Work

• Move the vehicle onto a solid, flat surface.
• Move the wheels so that they are straight.
• For vehicles with rear axle steering, steer the rear axle to the zero position. Refer to Rear Axle Steering . This is the only way to ensure that the rear axle steering is in the straight-ahead position.
• Vehicles without air suspension: deflect the springs several times and let settle.
• Electromechanical parking brake applied.
• The vehicle exterior lamps are off.
• All the vehicle doors are closed.
• Remove the label with the metal foil from the bumper cover, if necessary.
• Connect the battery charger for the battery support mode. Refer to BATTERY A, CHARGING .
• Before starting the calibration/adjustment, check the DTC memory and correct all displayed entries.

Procedure

-- Check which hole circle the rims have.

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

-- Insert the measuring paddle at both Calibration Tool - Wheel Center Mounting:VAS 6350/1A  and secure with the locking nut.

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

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

-- Place the Calibration Tool - Wheel Center Mounting:VAS 6350/1A  on the wheels so that any "anti-theft wheel bolts" are not connected to the wheel center mounting.

-- Adjust the measuring paddle using the 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 6350A  at distance -a- to the rear wheels.

• Dimension -a- = 1, 700 mm (66.93 in.)

-- Using the bubble level (level indicator) -arrow-, bring the Calibration Tool:VAS 6350A  into a horizontal position by turning the plastic bases.

-- Turn on the Calibration Tool - Linear Laser:VAS 6350/3A  on the Calibration Tool: VAS 6350A  .

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

-- Turn on the Calibration Tool - Spacing Laser:VAS 6350/2A  . Refer to Calibration Tool - Spacing LaserVAS 6350/2A Operating Instructions.

The following display appears 1 :

The display -2- shows how to position the Calibration Tool - Spacing Laser:VAS 6350/2A  .

• -arrow 1- : position with front edge
• -arrow 3- : position with rear edge

-- Press the corresponding button.

-- Hold the Spacing Laser:VAS 6350/2A  -2- for the distance measurement on one side of the calibration board flush to the catch bracket, as shown.

Courtesy of AUDI OF AMERICA, LLC

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

-- Push the measurement button briefly.

The laser switches on.

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

If that is not the case, correct the measuring paddle -1- height using the clamping screw on the Calibration Tool - Wheel Center Mounting:VAS 6350/1A  .

-- Use one hand to hold the Calibration Tool - Spacing Laser :VAS 6350/2A  firmly in the catch bracket on the Calibration Tool :VAS 6350A  ; the laser beam should be seen on the measuring paddle during this.

-- Then press the measurement button for the distance measurement briefly.

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

• "1, 700 m" (specified value: 1700 ± 2 mm (66.93 ± 0.08 in.)).

-- Repeat this measurement on the other side of the Calibration Tool:VAS 6350A  in the same way for the rear wheel.

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

-- If both measured values are not the same, then readjust the Calibration Tool: VAS 6350A  correspondingly until the distance values are the same on both sides.

-- Make sure the Calibration Tool - Line Laser:VAS 6350/3A  strikes the center above the emblem and that the level indicator remains centered. Adjust if necessary.
