Morning.....my SM 3 is glitching after working great all last year. the first screen is all zero'd out and the following screen has erroneous numbers too like coolant is at 0, ALT 0, etc. I know it is not my XFI 2.0 as i hooked up the laptop and the readings are all good. i unplugged and plugged several times and obviously it is getting power due to erroAny help appreciated
