HELP: Openflash Tablet is not powering up when plugged into my OBD2 port.

If your OFT worked before, but for some reason has stopped read more below.


  1. First, plug in your OFT to your PC using your USB cable. If it power up, then move on to the next section.
  2. Check your FUSE panel to ensure that the 12v is present at your OBD2 port. If you have access to one, try plugging in another scan tool to see if it turns on as well.

    The OFT uses the supply voltage from your port. If the fuse is blown, the OFT will not turn on.


Pin 16 should have +12v.
