Preparation
Important
- Observe ⇒ Rep. gr. 98; Necessity of calibration.
- There must be no entries in the event memory that would
hinder calibration.
- Check camera image on display unit for front information
display and operating unit control unit -J685-.
- Read and clear event memory using ⇒ Vehicle diagnostic
tester.
- Verify pitch circle of rear wheel rims, and prepare wheel
centre mounting -VAS 6350/1A- accordingly.
Vehicles with 17 mm wheel bolts
- Secure wheel centre mounting -VAS 6350/1A- with wheel
bolt adapter -VAS 6350/1-3A-.
All vehicles (continued)
Vehicles with 19 mm wheel bolts
- Secure wheel centre mounting -VAS 6350/1A- with wheel
bolt adapter -VAS 6350/1-4A-.
All vehicles (continued)
- Fit paddle -2- from calibration unit -VAS 6350A- to wheel
centre mounting -VAS 6350/1A--1-, and secure it using
clamping bolt.

- Fit wheel centre mounting -VAS 6350/1A- to wheel bolts of
rear wheels.
Important
- Fit wheel centre mounting -VAS 6350/1A- in such a way that
the anti-theft wheel bolts do not make contact with wheel
centre mounting -VAS 6350/1A-.
Important
- Paddles -2- must free to move smoothly just above the
ground.
- Position calibration field -1- from calibration unit -VAS
6350A- at distance -a- behind vehicle.

- Align calibration panel -1- parallel to paddles -2-.
Important
- Distance -b- must be the same on both sides.
Note
Make a note of dimension -b- for the subsequent calibration
procedure.
- Switch on linear laser -VAS 6350/3A- -1-.

- Align calibration field in such a way that laser beam -2- is
centred on rear badge
- Turn plastic feet under calibration field until spirit level
-arrow- is centred.

- Switch on spacing laser -VAS 6350/2A-, and hold it as
shown on display -1-.

- Press corresponding button of spacing laser -VAS
6350/2A--2-:

- -Arrow 1-: Fit with front edge
- -Arrow 3-: Fit with rear edge
- Fit spacing laser -VAS 6350/2A--2- with rear edge -arrow 3-
and press corresponding button.
- Position spacing laser -VAS 6350/2A--2- flush in bracket on
calibration field, and hold it in place.

- Press measurement button.
Important
- Laser beam from spacing laser -VAS 6350/2A--2- must hit
paddle -1-.
- If laser beam is not centred on paddle -1-, adjust paddle -1-
again.
- Note reading.
- Repeat procedure on other side of the vehicle.
Important
- Determined values must be the same on both sides.
- If the values differ, align calibration unit -VAS 6350A- again,
until the values are the same.
- Switch on spacing laser -VAS 6350/2A-, and hold it as
shown on display -1-.

- Press corresponding button of spacing laser -VAS
6350/2A--2-:

- -Arrow 1-: Fit with front edge
- -Arrow 3-: Fit with rear edge
- Measure and record dimension -a- using a commercially
available folding meter.

- Measure and record dimension -b- using a commercially
available folding meter.

- Enter dimensions -a- and -b- in "mm" in ⇒ Vehicle diagnostic
tester.
- Proceed as prompted by ⇒ Vehicle diagnostic tester.
