Hello, I have a CF450, the engine failure light is flashing.  Is it possible to read the fault with an ELM327?  Has anyone tried, on YouTube they diagnose a CF700 with an ELM327

I received ELM327 from AliExpress, I downloaded the application of the same device (Car Scanner) and I diagnosed the quad, everything worked, when choosing the vehicle brand all the car brands appear, at the end there is a brand like "OTHER", with this it has worked well. 
The problem was P0134, I was able to reset the control unit fault and now the flashing light is not there, perhaps it was an occasional fault or perhaps the error will appear again and in the end I will have to check the sensors.

Check the connector. No activity usually means it's lost all connection.

Thank you, I think the error was because the children were in the machine, they moved the key from one side to the other and then when turning the ignition on and off the error occurred.
At the moment everything works fine.

Regards
