Continuation of my saga from viewtopic.php?p=494796#p494796
So, everything seemed ok or mostly ok for probably a week w/no ! yellow car lights including thru the Memorial Day weekend (so, thru Mon 5/29), possibly going as far back as 5/17. Prior to 5/29, it looks like the last charge complete email I received was on Fri 5/26. Over the weekend, I did notice some wonkiness (I think) w/the NissanConnect app showing 0 miles and not being able to retrieve info. Wasn't clear if it was due to AT&T reception probs.
Drove to work on Tuesday morning 5/30 (still no warning lights). Parked, and turned on timer 1 (timer 2 was off) w/my midnight to midnight 80% timer. Turned car off, opened charging door, hoping someone would plug me in later or that I'd plug myself in.
I returned to my car in the afternoon which I found hadn't been plugged in. The 2 original cars nearby were still plugged in. Was planning to move my car to another level in the garage. Upon power up, I see the darn ! yellow car again. Checked DTCs and confirmed this was present:
P3131 000B EV/HEV System Shutoff Timeout EVC-220
I'm pretty sure I cleared it before. The car hadn't even been plugged in! Of course, after a few cycles, the warning light went away.
Later in the day, in the evening of 5/30, I did receive a charging complete email once I finished charging (to 100%, I shut the timer off). And, no yellow ! car was present. I do recall hearing my car recite stats from a Nissan feed that day (mentioning as of May 28th stats).
Will probably clear that DTC again to see if it and the yellow ! car come back.
