Leaf won’t start or charge - 12v is good

Tue Jan 05, 2021 2:25 am

Yesterday i got to my leaf and the car wouldn’t start. So I contacted a local enthusiast and he recommended i charge my 12v, so i did. To my surprise it started right away but as soon as i shut it down to charge it wouldn’t and also wouldn’t restart again. I have checked and my 12v is in excellent condition.

When i pull up some codes on leafspy i was shown the following:

P31E7 00C0 EV/HEV Restart Inhibition EVC-310
P0AA6 00C0 EV/HEV Hybrid Batt Volt Sys Isolation EVC-157


My car is a gen 1 2011 24kwh leaf

It would be of great help to me if I could get this sorted, thank you.

There is some indication that there are one or more bad cells in the main battery. You will of course need to verify that. I'm sorry.

I see that you've already posted in another existing topic that is very similar. One of the mods will probably move this post there. I'll leave it up for the morning, anyway.

What do you mean by two dead battery cells? Has the pack been opened?

I’m not sure when i got the car it didn’t have any dead cells but after a while of having it, I checked on the leafspy and saw two dead cells

Cells shown in red on LeafSpy are just balancing, not dead. A dead cell would have no graph line above it, and you likely wouldn't be able to drive the car with 2 dead cells.

ahh, I understand. right now I have sent it to a local leaf mechanic and he is suspicious of the PDM because the car will not accept charging. I'm still a bit worried as he has never seen a case like this.

If he specializes in Leafs, then you have a decent chance of a good diagnosis. By "good" I mean accurate, though, not necessarily cheap.

What is the age of your aux battery; what was your charging procedure; what test data do you have as evidence that it is in "excellent" condition? Seen this too many times to just gloss over the root cause.

I don’t have that much data but i put a brand new battery in it and it stayed the same. I also tried batteries from my other cars that could fit into the leaf with a similar capacity but same results
