Update-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.
 If software updates or flash campaign/actions are performed on a vehicle, a charger with at
least 70A charging current MUST be used in order to avoid problems during software
updates and flash campaign/actions.

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!

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, 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.
