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 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.
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.
