Technical Bulletin
Note:
DO NOT diagnose or replace any parts before performing the update function as explained in this bulletin.
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
# VVT-12-02. 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 VAS 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.
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.
• Update the Engine Control Module using the SVM Unit code as listed in the table below:
