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 the ODIS service diagnostic applications 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/X or 6160/X 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.
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!
