12.4.2 Calibration Preparation Work

Special Tools And Workshop Equipment Required

Requirements

Move the vehicle onto a secure flat surface.
Apply the parking brake - the vehicle must not move during the measurement.
Place the front wheels in a straight-ahead position, steering wheel in 0 position.
No persons may be in the vehicle interior during the measurement.
Do not open and close the vehicle doors during calibration.

Procedure

Connect the Vehicle Diagnostic Tester.
Turn on the ignition.
Secure three suitable wheel bolt adapters for the wheel bolts on each -VAS6350/1-.
Place the measuring paddle on both -VAS6350/1- and secure them using a clamping screw.
Place the -VAS6350/1- onto the wheel bolts on both rear wheels.
- -VAS6350/1- must be in wheel rotation center.
NOTE: Attach the -VAS6350/1- onto the wheels so that any installed "anti-theft wheel bolts" are not connected to the -VAS6350/1-.
Adjust the measuring paddle with aid of lock bolts so that they move freely just above the floor. Check the paddles for ease of movement.
- The measuring paddles must move easily.
- The measuring paddles must be vertical.
Position the -VAS6350A- at distance -a- to the rear wheels.
- Dimension -a- = 1700 ± 2 mm
Switch on the -VAS6350/2-

The Following Display Appears:

The display shows how to stop the -VAS6350/2-. Press the corresponding button.

Hold the -VAS6350/2- -2- flush in the bracket on one side of the calibration board (attach with rear edge). The -VAS6350/2- -2- must sit securely on the bracket.
Press the measuring button briefly.

The laser switches on.

Make sure that laser beam from -VAS6350/2- -2- hits lower, enlarged part of the measuring paddle -1-.

If this is not the case, correct the measuring paddles accordingly via clamping screws on the -VAS6350/1-.

Use one hand to secure the -VAS6350/2- in the bracket on the -VAS6350- while the laser beam is visible on the paddle.
Then press the measurement button for the distance measurement briefly.
Write down the value.
- "1, 700 m" (specified value: 1700 ± 2 mm).
Repeat this measurement on the other side of the -VAS6350- in the same way for the rear wheel.

The distance value must be the same on both sides.

If values are not identical:

Align the -VAS6350A- long enough so that both sides are identical.
Secure the -VAS6350/4- for the lane change assistance to the -VAS6350- mount.
- When installed correctly, vehicle electrical system voltage line must be connected at bottom left of -VAS6350- (as seen in direction of travel).
- Dimension -a- = 543 mm (measured from upper edge of - VAS6350- to workshop floor).
The adjustment dimension is set with the measuring point -arrow- on the base of the -VAS6350- on the scale of the steel ruler -1-.
- Left setting = 865 mm (read on measurement scale -1-).
Connect the calibration unit for -VAS6350/4- for the lane change assistance to the vehicle electrical system voltage.
Bring the -VAS6350A- into a horizontal position.
To do so, twist plastic feet under calibration device so that air bubble in level is located exactly in the center of the indicator -arrow-.
Wear "laser protective eyewear".
Turn on the -VAS6350/3A- on the -VAS6350A-.
Align the entire -VAS6350A- so that the laser beam shines on the center of the vehicle rear above the VW logo.
Check right and left distance between catch bracket on the - VAS6350A- and measuring paddle -1- on wheel mountings again.
- Specified value: 1700 ± 2 mm
