I occationally get a Firmaware Update Failure. It says to try disconnecting the scanner from the vehicle and try it again, but it doesn't say how to actually do it. It happens automatically when I try to scan (randomly and occationally) but I can't make it happen when the car isn't hooked up. Then it just says it can't find the vehicle.
By the way, I have Firmware version 112. Is there even a newer version? Why is it doing this? My scanner is not very dependable. I even had my first write failure yesterday which left me with a no start condition. It was repaired during a reflash, though, but it was scary.
