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:

Prior to launching VAS-PC application and starting control module update process, confirm tester screen saver and power settings in accordance with Special Tools and Equipment - Service Information Circular # VSE-08-18.
Failure to do so may result in the tester entering power save mode during data transfer, and subsequent control module failure.

When using a VAS 6150, 5051B or 5052A tester in conjunction with a VAS 5054A wireless transmitter head for a flash procedure, please connect a USB cable between the transmitter head and the tester. Failure to
do so may lead to errors during the flash procedure.
