Proceed to Section E

Section E – 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):

Check and confirm that you have a LAN
connection .

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

Start a connections test and
verify that all connections pass.

•

Open the hood.

•

Open the battery cover.

•

Attach the GRX3000VAS Tester/Charger (or
equivalent) to the vehicle battery jump point and
ground jump point.

•

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.
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.
•

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.

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.

Upon ODIS startup, verify the “Diagnosis”
operating mode is selected .

NOTE
KESSY Vehicles!
It is REQUIRED to insert the key into the reader coil
, or place the key in the closest proximity
possible to the reader coil throughout the flash process.

NOTE
Before, during, and after the flash process and control
module interrogation phases, any number of instrument
cluster warning indicators (glow plug, check engine,
brake, ABS, etc) may illuminate, flash, or otherwise turn
on and off. It is also possible that other interior or
exterior components such as radio/infotainment
system, lamps, etc. may turn on and off. This is a
normal condition during this process. The illumination
of instrument cluster lamps (etc) will cease once the
ODIS session has ended and the ODIS diagnostic tool
is disconnected from the data port.
