SERVICE

Update-Programming Procedure:

Tip:

To Update-Programming using SVM, review and follow instructions in Technical Bulletin Instance 2014603 "Software Version Management".

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: Ensure that SVMs are always performed while using the most recent ODIS Service application and diagnostic content versions (Application Version 4.0.0 and VW Diagnostic Content Version 2.33.2 (or higher) .

Prior to launching the ODIS service diagnostic applications and starting control module update process, confirm Date/Time & Time Zone.

The Windows date/time and time zone settings are used by the diagnostic software as a component of the diagnostic logs submitted for warranty purposes. If the date/time and time zone are incorrect on submitted diagnostic logs, warranty claim reimbursement may be questioned and/or delayed.

Ensure date/time etc. settings are correct as follows:

From the Windows desktop toolbar, double click on the local time indicator (typically found in the lower right corner of the desktop).
Use the tabs to ensure the current date/time, and time zone applicable to your location is set correctly.

Always connect a USB cable between the VAS 5054A or VAS 6154 Diagnostic Interface and diagnostic device for SVM procedures. Using a diagnostic interface with a wireless connection (Bluetooth or WLAN Infrastructure) is prohibited. Failure to do so may lead to errors during the flash procedure.

VAS tools must only be used with their power adapters plugged in. Under no circumstances should they be used on battery power alone during the programming procedure.

Critical Warning :: The Midtronics Battery Charger must be connected to the vehicle battery for the duration of the programming, to ensure the battery state of charge remains above 12.5 volts during the update process. If the battery drops below 12.5 volts, the programming could fail which may result in damage to the control module. Control modules damaged by inadequate voltage will not be covered under the warranty policy. The technician should verify the vehicle voltage prior to starting the update process, and should monitor the voltage for the duration of the update.

WARNING: Radiator Fan(s) may cycle ON high speed during the Update Process! There is a 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!

Update the Engine Control Module using the SVM Unit code as listed in the table below:
