Scott Disick & Tyga Go Luxury Car Shopping After Lunch At Il Pastaio In Beverly Hills 12.5.15 My Genisys Evo does the same on some cars
When I was diagnosing a Kia Rio, it said the car was going 40 MPH in the shop, the idle speed was 21982 RPM and a few other nonsense numbers. I couldn't use any of the data, so I looked at it in Global OBDII and the datastream was fine.
The Genisys is a decent scanner for the money, but has it's limitations. On some vehicles it won't work on some functions.
What is really annoying, you go into demo mode and a function or PID is there, but in real time data, it doesn't read or the PID is missing. Jeep fuel sync comes to mind on my old Genisys system 2.0.
