Section B – Update Engine Control Module
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 (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.

The VAS Diagnostics Interface MUST ONLY be connected to the tester with a USB cable.
•

Performing a software update using a Bluetooth or WiFi 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
•

Damages resulting from improper repair or failure to follow these work instructions are the dealer’s
responsibility and are not eligible for reimbursement under this action.

•

Diagnosis and repair of pre-existing conditions in the vehicle are not covered under this action.

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.
