We've had pretty much the same problem with you here in the UK
So our Leaf 24 kWh 2017 isn't starting.... this is the second time this has happened this month, read on:
1st Problem
10th July 2018
•Car would not start “EV system warning light” showing
•Car taken by Nissan recovery to local Nissan dealer "EV specialist". Incidentally this is not the dealer that supplied the car to us.
•Diagnosis by dealer was that there wasn’t enough charge in the 12V battery. Suggested that we has left a light on. They suggested that we keep the car on charge when it's not being used. I kind of felt they didn't really know what they were talking about and were fobbing us off. They tested the 12V battery and said that it was healthy.
After reading various articles about problems with EV 12v batteries we purchased a 12v Battery charger just in case this happened again.
Second Problem
28th July 2018
Repeat of problems from 2 weeks before
Actions taken
•Battery is removed from the car and left to charge on a trickle charge . Charger reports battery is full. •Battery is put back into car. Still the same problem
•We try and jump start the car using our other car ( a Hyundai Santa Fe fitted with a huge battery). This is to rule out a battery that has really died but still looks normal. Still the same problem
•I test the voltage of the battery using a multimeter . This reports that the battery is producing 12.5volts. Seems healthy. Car still has the same issue.
No lights have been left on, no accessories have been left on. Nothing appears to be draining the battery. The 12V battery appears to be ok.
Note that the main battery will not take any charge ( it wouldn’t during the first problem either. Incidentally the main battery is about 50% charged ( showing 40 ish miles)
Other info
We are using a Chargemaster 7kW Homecharge unit- this plugs into the J1772 connector ( right connector on the car). We almost always use this to charge the car. We have used the CHAdeMO port half a dozen times only.
Update as of today. In order that we don't get fobbed off by the dealer I have purchased an ODB2 Bluetooth device and have downloaded LeafSpy Pro to my iPhone
The Error logs from LeafSpy Pro are:
P31E7 000B EV/HEV Restart Inibition EVC-310
P0AA6 0008 EV/HEV Hybrid Batt Volt Sys Isolation EVC-157
U1266 0208 Multi AV TCU Conn AV-92
So this tallies with your problem ( at least some of your codes).
I'd be really interested to know what your dealer has found was wrong . I hope that the car doesn't need to be taken apart to sort out the problem.....
