Alright, so I disconnected the 12v and it worked. Kind of strange tho, cuz when I disconnected it it was on 62.5, and when I turned it back on it went straight to 61.8, so the ECU seems like it was still keeping track..Must have been a guage cluster issue.
Now for another interesting thing: the reason I didn't reset the 12v right away (just did it today) was cuz it didn't seem urgent. So, I'm driving around today and I was like 4 notches down from a full IMA charge and all the sudden it just started dropping..All the way down to 3 notches away from complete discharge in about half a mile. No IMA light or anything..Just started to discharge for no reason. Wtf?
So, I reset the ECU and it's at full charge again and working just fine. Is there a known issue with the guage clusters where they just start acting funny?
