Yes i too had the same problem it would not recognize the car but my passthru device wasn't recognized. Change the adapter setting to COM 2 and see if that helps. For some reason that port i remember has to be set and how i set mine. Try to connect to the vehicle again after the change. It shouldn't stop on that error screen but should only give you an error about not seeing if the ignition is on.

You can also run the toyota mvci firmware update tool only to make sure it sees the cable but not to update it. I can provide the file if you don't have it and a screenshot what mine looks like if the COM 2 setting doesn't work.

ok ok I understand, change the settings on com 2 and check if something will give. I will add that my interface is a Chinese mvci clone, originally purchased for the Toyota software, the interface exactly has a sticker on the mini vci j2534.  and in the attachment I send a picture of my mvci see if yours is the same.


send me a photo of your mvci. your mvci is clon or original ??
