Section B – HV Battery Software Update
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 “Current ODIS Service Version” circular found in Elsa2Go Service References.
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 (or higher, if directed in the work instructions) 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.
Flash process through “Audi Flashing” not Guided Fault Finding (GFF).
•
DO NOT USE Guided Fault Finding (GFF) to perform this flash. Using GFF will cause the flash to
take longer. Requests for additional time will not be considered.
The VAS Diagnostics Interface MUST ONLY be connected to the tester with a USB cable.
•
Performing a software update using a Bluetooth or Wi-Fi 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 or WiFi.
NOTE
•
All campaign software updates must be completed during a single, standalone ODIS Diagnostic Session.
You must fully complete this campaign and send all logs before beginning any other campaigns or
operations.
•
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 update process.
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!

warranty claim may not be reimbursed if there is no confirmation response to support the claim.
CRITICAL REPAIR STEP
STOP!

below prior to starting the flash.
•
Switch off all consumers, air conditioning, heater blower motor, lights, heated seats, etc.
•
Connect battery charger.
•
Ensure the latest version of ODIS is downloaded.
•
Ensure diagnostic head is connected to ODIS tester via USB cable.
•
Move selector lever to P.
•
Switch the hazard flashers on.
•
Verify that the ODIS version is 2.37.7 or later. If the current ODIS version
is below 2.37.7, do not start the flash until the scan tool has been
updated to ODIS version 2.37.7 or higher.
•
