I have a MPVI2+ and a winds tablet that I use with it which I plan to eventual make as a dash for my LS swap. Anyways, I?ve scanned my donor car (a 2007 Chevy express) many times and VCM scanner works, but today I?ve been trying to scan my friend?s 2015 Silverado to help him out. The vehicle connects and displays all the proper info (but the gauges are empty) then I go to press the ?start scan? circle and it greys out for a few seconds then comes back to normal. I?ve tried resyncing interface along with restarting the pc, truck, plugging and unplugging the usb, and installing version 4.12.4. Thank you in advance for any help.
