Hi everybody,
I am having an issue with my 1994 300ZX twin turbo. I have been trying to run the Nissan data scan diagnostics program and every time I connect the car to my phone or laptop the message " unable to connect" keeps appearing. I have both the laptop and android versions of the program and the cable I am using appears to be working as the lights are coming on when I connect it all up. My car is a Japanese domestic market car that was imported. Has anybody had any similar issues?? Any help would or suggestions would be appreciated.

Kind regards
Steve
