Section B – Update Engine Control Module Software
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.
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.
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.

NOTE

This software update will bring the ECM software level to 9970 (or higher) and may address some DTCs.

If the car arrives with a MIL and/or one or more of the DTCs described below and the ECM software level is
lower than 9970, the 24Fi software update should be performed before diagnosing the fault(s).

The DTCs are separated out by ECM part number. If the DTC stored in the vehicle does not match the ECM
part number/DTC chart below, further diagnosis may be required.

Diagnosis and repair of any DTC will not be covered under this action.
