Section F – Software Update Procedure
NOTE
Prior to launching the VAS Diagnostic Tester and starting an update, ensure the following conditions are
met;
The ODIS software is completely up to date.


Refer to the “Alerts” section on ServiceNet home page for the current ODIS version.

The battery charger is connected to the vehicle battery and remains connected for the duration of
the software update.


Battery voltage must remain above 12.5 volts for the duration of the software update. Failure to
do so may cause the update to fail, which could result in damage to the control module. Control
modules damaged by insufficient voltage will not be covered.

The screen saver and power saving settings are off.


Failure to do so may result in the tester entering power save mode during the software update,
which could result in damage to the control module.

The VAS Diagnostic Tester is plugged in using the supplied power adapters.


Under no circumstances should the tester be used on battery power alone during the software
update. Failure to do so may result in the tester powering off during the update, which could
result in damage to the control module.

If using the Bluetooth VAS 5054A transmitter head, it is connected to the tester with a USB cable.
NOTE
Using Bluetooth for this action is PROHIBITED!
Damage caused to electronic components (e.g. ECM, TCM, etc.) during the SVM flash process is not covered.


Performing a software update using a Bluetooth connection increases the risk of losing
connection during the update, which could result in damage to the control module.
It also greatly increases the time required to perform the update. Requests for additional time
or parts will be denied if the GFF log shows the update was performed using Bluetooth.

The Bluetooth function of the scan tool is physically switched off .

WARNING
Radiator Fan(s) may cycle ON high speed during the Update Process! There is a serious risk that personal injury
may result if contact is made with spinning fan blades. Keep hands and all objects away from Radiator Fan(s) during
Update Process!
TIP
To Update-Programming using SVM, review and follow instructions in Technical Bulletin 2014603: Software Version
Management (SVM) Operating Instructions.
The SVM Process must be completed in its entirety so the database receives the update confirmation response. A
warranty claim may not be reimbursed if there is no confirmation response to support the claim.
Things to check before starting Software Version Management (SVM):

Verify your network connection through
LAN by checking the connection icon
(lower right of the home screen).

Check the icon within the ODIS
software that you have a connection.

Within the Connection Tab, verify that the
Connection type(s) display “Internet” .

Start a connections test and verify
that all connections pass.



At this time, refer to the “Alerts” section of ServiceNet
to verify that the most recent version of ODIS
Software is loaded to the VAS6150X Diagnostic
Tester (or equivalent). Failure to flash the vehicle
using the most recent version of ODIS Diagnostic
Software will cause faults in certain features of the
flash operation.



Failure to validate the ODIS Diagnostic version
before flashing the vehicle may result in flash failure,
and may delay if not negate the payment of the
emissions modification.



Switch the ignition on.



Apply the parking brake.



Switch the headlights off.



Connect the VAS6150X Diagnostic Tester (or
equivalent) to the vehicle.



Start the ODIS program.



Open the hood.



Open the battery cover.



Attach the GRX3000VAS Tester/Charger to the
vehicle battery.

TIP
Time to connect battery charger is included in the GFF
diagnostic protocol time units.
NOTE

STOP!
All TDI flashes MUST be completed during a single,
standalone ODIS Diagnostic Session. You MUST fully
complete this campaign and send all GFF Paperless logs
before beginning any other campaigns or operations.
You MUST also conclude any other campaigns or
operations that have been started and end the
corresponding diagnostic session and send all GFF
Paperless logs before beginning this operation. Failure
to independently separate the ODIS diagnostic session
for this campaign will cause problems updating the FAZIT
server in Germany and will delay if not negate the
payment of the emissions modification.
IMPORTANT!
If there are any ODIS “Hot-Fix” patches installed, they
MUST be removed from the scan tool before beginning
this operation. ODIS “Hot-Fix” patches may affect the
flash process.



Confirm that scan tool is communicating with the
diagnostic head by USB .
o

If the Bluetooth symbol is shown then disconnect the diagnostic head
from the vehicle and reconnect the USB
cable to the diagnostic head and then
reattach to the vehicle.

NOTE
KESSY Vehicles!


If loss of communication between the reader coil and
the key occurs during the flash, it may damage a
control module.
If equipped with a removable reader coil cap, it is
REQUIRED to remove the reader coil cap and insert
the key into the reader coil, or secure the key in close
proximity to the reader coil throughout the flash
process.
If the reader coil cap is not removable, it is REQUIRED
to secure the key to the steering column in close
proximity to the reader coil using a residue-free
adhesive or tape, an elastic cloth or stretch bandage,
or other improvised retaining device.
