UPDATE Technical Bulletin
NOTE:
• Elsa is the only valid inquiry/verification source. Check Elsa on the day this vehicle UPDATE will be
performed to verify vehicle eligibility for the UPDATE. Status must show “open”. Attach an Elsa printout
showing the “open” status to the repair order.
• If this UPDATE appears to have already been performed but the code still shows open in Elsa, contact
Warranty before proceeding further. Another dealer may have recently performed this UPDATE but not
yet entered a claim for it in the system.
• Elsa may also show additional open action(s); if so, this work can be done while the vehicle is in for this
UPDATE.
• Contact the Warranty Helpline (U.S.) or the Warranty Campaign Specialist (Canada) if you have any
questions.
•

Enter the VIN in Elsa and proceed to the
“Campaign/Action” screen

TIP
On the date of repair, print this screen and
keep a copy with the repair order

UPDATE Technical Bulletin
SVM Update Instructions
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 a Bluetooth transmitter head, it is connected to the tester with a USB cable.
•

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 <see pictures below>.
