Important Note:

  1. DO NOT change the “User Type” when you will run your TIS Techstream for 1st time! LEAVE IT with the Default option! “Official” Dealer/Repairer with other words…
  2. in [ VIM Select ] option, please select the [ Xhorse — MVCI ], not [ TIS Techstream VIM ]
  3. If you get the following reminder while using the program:

— — — — — — — — — — — — — — — — — — — — — –

Register Techstream Software (S314–03)

Network connection is unavailable. A network connection is required to use Techstream software.

You can only connect 29 more times without a network connection before software registration is required.
