Service bulletin AVT-13-15

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

If a VAS diagnostic tablet or laptop device is used to perform Software Version Management (SVM) or immobilizer adaptation, it is necessary to connect a USB cable between the tablet or laptop and their Bluetooth (wireless) matched VAS 5054A Transmitter Head. This ensures uninterrupted data transfer. Use the following procedure to install and configure a VAS 5054A transmitter head for USB (cabled) operation on a VAS diagnostic laptop or tablet with ODIS Service ONLY ?i.e.: VAS-PC not installed or previously uninstalled. Attempting to use the USB cable without first performing the initial USB configuration may cause the tablet or laptop operating system to "lock up", which requires a forced, manual restart and loss of the session diagnostic log.
