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.
