Section F – Software Update Procedure (All Criteria)

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 or WiFi transmitter head, it must be 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 .
