VVDI MB BGA Tool error “please provide extra power to car” solution

After trying to use Xhorse VVDI MB BGA Tool to read on two Mercedes sprinter 906 cars, I got error message “Car voltage is 7.1V, please provide extra power to car before continue.”  (Shown as bellow).

My friend has vvdi mb and it works without this adapter (power adapter).



Xhorsevvdi.com engineer replied:

Please make sure your car has full voltage before using Xhorse VVDI MB BGA Tool.


Good luck!
