Guess what's back! HV battery issues!
I've had all the idiot lights come on a couple times in the last few months, but both times my Ultragauge didn't see any codes (or even that the CEL was on) so I just cleared the codes and went on my way. It happened again the other day while my wife was driving. This time I was able to check the codes with my bluetooth scanner, and it looks like there's a module or two that needs some loving.
