Normally, your computer will automatically recognize the OHP ELMconfig OBD2 USB adapter as soon as you connect the device to your vehicle. There are times however when your computer fails to read the device and a "No ELM Found" error message occurs. There are many possible reasons why this error message appears - like an outdated device driver, incompatible computer system, a malfunctioning unit, and many others. Solutions for such error message vary. Here are some common procedures that you can apply in order to diagnose and potentially sort out the problem.

Also, the device is currently having compatibility issues with Windows Surface and Surface Pro computers. So, please find another computer if you're using one of these incompatible computers. 

3. Test the Physical Connections

Check and test the connection of the device to the OBDII port of your vehicle and to the USB port of your computer for any "loose" connection. Try to adjust or move the connectors around and see if you gain any connection. Also, flip between the MS-CAN/HS-CAN switch as you make the adjustments.
