Replace complete fiber optic cable if possible.
Make sure that the face surfaces of the connectors do not become
soiled.
If disconnecting the connectors: Attach Fiber-Optic Repair Set -

Notes on MOST Bus

The optical Data bus “MOST Bus” is used in addition to the CAN
Bus.
A fiber-optic cable is used as a “connecting cable”. Fiber optic
cables are routed inside corrugated tubes for protection.
Replace complete fiber optic cable if possible.
Make sure that the face surfaces of the connectors do not become
soiled.
If disconnecting the connectors: Attach Fiber-Optic Repair Set -
Connector Protective Caps - VAS6223/9- .
When installing fiber optic cables, make sure not to go below the
minimum bending radius of 25 mm. Do not crush or kink fiber optic
cables.

The optical Data bus “MOST Bus” is used in addition to the CAN
Bus.
The connection to the other Data Bus systems in the vehicle are
provided by the Data Bus On Board Diagnostic Interface - J533- .
A fiber-optic cable is used as a “connecting cable”. Fiber optic
cables are routed inside corrugated tubes for protection.
Replace complete fiber optic cable if possible.
The front surface of the connectors must not be dirty.
If disconnecting the connectors: Attach Fiber-Optic Repair Set -
Connector Protective Caps - VAS6223/9- .
When installing fiber optic cables, make sure not to go below the
minimum bending radius of 25 mm. Do not crush or kink fiber optic
cables.

WARNING

Danger of unintended engine ignition

Turn off the ignition and remove the ignition key from the ve‐
hicle interior for all work performed on the high voltage vehicle.

DANGER!

Damaged high voltage components may produce dangerously

high voltage.
Note the following when working near high voltage compo‐
nents and cables:
♦ Do not use tools that have sharp edges, that are used for
cutting or shaping, or that generate heat, such as welding,
soldering, hot air or thermal adhesive equipment.
♦ Inspect the high voltage components in the area where the
work will be performed before starting the procedure.
♦ Perform a visual inspection of the Electric Drive Power and
Control Electronics - JX1- , the Electro-Drive Drive Motor
- V141- , the Electrical A/C Compressor - V470- and the
high voltage cables when working inside the engine com‐
partment.
♦ Perform a visual inspection of the high voltage cables and
the covers when working on the floor panel.
♦ Perform a visual inspection of the high voltage cables and
the electro-box with the High Voltage System Mainte‐
nance Connector - TW- when working in the rear of the
vehicle.
♦ Perform a visual inspection of all of the potential equali‐
zation cables.
Note the following when performing the visual inspection:
♦ None of the components may display any exterior dam‐
age.
♦ The high voltage cable insulation and the potential equal‐
ization cables may not be damaged.
♦ The high voltage cables may not be deformed in any way.
♦ Each high voltage component muss be labeled with a red
warning label.

Calibration board alignment

– Position the calibration platform behind the vehicle at a dis‐
tance of 1.47 m to 1.90 m to the rear wheels, see
-dimension A- in the illustration. Refer to ⇒ page 157 .
– Bring the Calibration Tool - VAS6350- into a horizontal posi‐
tion.
– Twist the plastic feet under the calibration board so that air
bubble in level is located exactly in the center of the indicator
-arrow-.

WARNING

Make sure light does not reflect off the calibration platform.
Reflections affect the Rearview Camera - R189- and may
make it impossible to perform the calibration.

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

-1- on the calibration board and align the entire Calibration
Tool - VAS6350A- , so that the laser beam points to the middle
of the vehicle height above the Audi rings.
– Make sure the Audi rings are centered on the rear. Adjust the
laser beam as needed.
Continue calibrating the Rearview Camera - R189- . Refer to
⇒ “9.4.2 Rearview Camera R189 , Calibrating”, page 158 .

Note

Attach the Calibration Tool - Wheel Center Mountings -

VAS6350/1- onto the wheels so that any installed “anti-theft”
wheel mounting bolts are not connected to the Calibration Tool -
Wheel Center Mountings - VAS6350/1- .

– Adjust paddle with aid of clamping screws so that they move

freely just above the floor. Make sure the paddles move easily.
– Install and align the Calibration Tool - VAS6350- . Refer to
⇒ “9.4.1 Calibration Tool VAS6350 , Installing and Aligning”,

Distance measurement:
– Switch on the Calibration Tool - Spacing Laser - VAS6350/2- .

The following display appears:

– Hold the Calibration Tool - Spacing Laser - VAS6350/2- -2-

flush in the bracket on one side of the calibration board. The
Calibration Tool - Spacing Laser - VAS6350/2- -2- must sit
securely in the bracket.
– Press the measuring button briefly.
The laser turns on.
– Make sure that the laser beam from Calibration Tool - Spacing
Laser - VAS6350/2- -2- hits on the lower, enlarged part of

Display readout
– Note the value read off.
– Repeat measuring procedure in the same manner for the other
rear wheel on the other side of the Calibration Unit -
VAS6350A- .
The distance value must be the same on both sides.
If values are not identical:
– Align the Calibration Unit - VAS6350A- long enough so that
both sides are identical.
Pay attention when aligning the Calibration Unit - VAS6350A- ,
that the Calibration Tool - Linear Laser - VAS6350/3- from the
Calibration Unit - VAS6350A- strikes the center of the Audi rings
and the indicator of the level remains centered. If necessary,
make further corrections.
Dimension measurement -H-:

– Measure the height of the Calibration Unit - VAS6350A- , di‐

mension -H- (top edge platform - floor).
Enter the height and distance dimensions into the Vehicle Diag‐
nostic Tester in “millimeters”.
