Curious.........how was this procedure figured out???


I think using the word "procedure" might be a bit generous. ;)
I'm not the one who figured it out, but the reasoning is logical: if the TCU is in fact "timing out", then a "reboot" of the module would probably correct that. Luckily, there's a simple way (fuse #34) to power cycle that module without too much difficulty...and it obviously works. :D
I simply put a sticky label on the fuse holder/cover so I don't have to "hunt it down" every time my car stops communicating.


Hello fellow LEAF-ers :)

I am in the same boat, I tried the fuse procedure to no avail...

Found only one fuse of 20A noted as audio in the fuse box perpendicular to the 12V battery? Is that the one? Can someone post a picture of the location? TY!!

Here's my saga:

Nissan LEAF SL 2013, purchased in July 2014 - 36,500 miles, now at 256 GID's ~ 91%.

My telematics unit was upgraded to 3G on 12/22/26 and I paid $199.
On 7/1 I started having issues with the telematics unit – not being able to connect using the official NissanConnect app nor the web site so I brought it to the dealer.
On 7/3 the dealership said that they could not verify my concern – in the paperwork - however I saw it working as it was charging there that day.
On 8/25 started having issues with the telematics unit – not being able to connect using the official NissanConnect app again - so I brought it to the dealer - again.
On 8/30 the dealership said that telematics nit had internal failure codes U1A00 and U1A05 and they replaced it and said working correctly.
BTW They tried to tell me that I needed to pay $480 for the replacement saying that the telematics unit only had a software update back in
On 8/31 – stopped working and I made an appointment for next day
On 9/1 – started working in the AM and brought it to the dealer- the dealership said that they could not verify my concern – in the paperwork - as there are no error codes? However the telematics/ NissanConnect app did not work anymore since that day…
On 9/5 – called Nissan around 6 PM and spent time with the tech to do a step by step procedure to no avail. I was told I will get a call within 48 hours. Did not happen…
On 9/7 – called Nissan tech directly around 6 PM using their ID and left a message – no call back
On 9/8 – called Nissan tech directly around 6:30 PM using their ID and left a message – no call back
On 9/11 – called Nissan tech directly around 4:30 PM using their ID and left a message – no call back
On 9/11 – called Nissan around 4:30 PM and talked to another rep who said I should wait
On 9/11 – called Nissan tech directly around 5:30 PM using their ID and left a message – no call back
On 9/11 – called Nissan dealership and was told that they cannot do anything
On 9/12 – called Nissan tech directly around 3:40 PM using their ID and left a message – no call back
On 9/13– called Nissan tech directly around 2:36 PM using their ID and left a message – no call back
On 9/13– called Nissan tech directly around 4:56 PM using their ID and left a message – no call back
On 9/13– called Nissan around 4:48 PM and talked to another rep who said they submitted twice a request to Nissan support (?!) and that they did not hear back but that he knew they were very busy due to a new deployment and that this may be a bug that happened to a few other users over the summer
On 9/15– called Nissan tech directly around 6:34 PM using their ID and left a message – no call back
On 9/16– Tweeted the above + pics/screenshots to Nissan direct message around 6:34 PM

"I have more pics if you want... as it's been more than 11 weeks since this issue started. While I read the Nissan's disclaimer on the telematics, it is not acceptable not to have access at the remote charging and climate control during a hot summer! An EV is a special type of vehicle that almost REQUIRES telematics support due to its unique requirements to control and monitor charging - since the real miles are less than the 80 miles or so per charge...Please advise:1. When can I expect this to be fixed?2. When will I be compensated and at what level? :

The ! yellow car generally goes away after a couple power cycles, unless another DTC (diagnostic trouble code) is triggered. If you use something like Leaf Spy, you can see the DTCs.

If you clear them all or clear it for that system, you can wait for the yellow ! car to come back and see if the same DTC is has returned.

BluDragoon: Since you've obviously wasted a boatload of time, I'd try these:
- make sure you still login thru the owner's portal (https://owners.nissanusa.com/nowners/). You can also trying refreshing there. I suspect that'll fail or not be able to retrieve current info.
- disconnect your 12 volt for 5+ minutes and reconnect. Try signing in on from the car's head unit.

Unfortunately, I doubt these will help.

For those w/the upgraded TCU that are sometimes hitting yellow ! car accompanied by DTC P3131, clearing it and then both return later AND those who aren't having any of these, I'm wondering about these settings on your car.

I've not had a single yellow ! car and DTC P3131 since 8/31/17 on my upgradd '13 after clearing that stuff and doing the below.

Zero Emission Menu > Charging Messages > Saved locations for unplugged messages: I have no entries there. I deleted them all.
Zero Emission Menu > Other Settings > Autosave New Charging Station: I have all 3 types (Quick, Standard and Trickle) NOT selected.

So far, that seems to be the key to having no problems. Of course, this was never an issue w/the old 2G TCU.

So, for those w/no problems, are your settings like the above?

For those w/problems, do you have any Saved locations for unplugged messages stored? Do you 1 or more types selected for Autosave New Charging Station?

I do not have any of the issues you mention. I do occasionally have to pull the fuse to reboot the TCU. I'm still using the original 12v battery. If the car does not charge everyday, the battery will drop low enough to cause issues. I have all the settings the same as I had with the orginal TCU. I have it set to send all possible messages. My home charger is saved, and I get a message if not plugged in within 5 minutes of turning the car off. The only difference from before, is I don't get the Charging Complete message, unless it actually does some charging (starts with SOC below 100%). With the old TCU, I got the message every time the charge timer engaged, even if it didn't actually add any charge to the battery.

OK, so after a week with the new TCU, twice I got a car light with "!" on it in the morning after driving the day before. Did a scan with LeafSpy, and sure enough, low 12v batter level. Not enough to prevent start, but looks like it's well on it's way. Also, my 12v USB charger, the LCD read 11v.

Curious though, I'm new to being able to remote-start climate controls with the app. I did it this morning when I got that light. So, is it potentially running down the 12v battery to power the fan/AC? I would have thought that, remote climate control would also turn on traction battery charging to keep the 12v battery up.

If its plugged in the power to run the AC comes from the charger.

OK, so the fact that the 12v battery was low this morning had nothing to do with the climate control then as it was attached to the charger. I had even turned on the charger for the car about an hour before I had started as well. Seems odd that the voltage was low after both of these scenarios.

I drove home for lunch, parked and powered off. Came back to work, and no noticeable warning lights. Voltage was at 13v while driving back. I've not left the OBD2 connector attached either, so no other accessories attached. I'll need to get the battery tested.

AFAIK when the EVSE (read: charger) is connected the 12V battery is not being charged by the main traction battery through the DC-DC converter (read: big battery to the little battery) - which is the only way the 12V battery gets charged.

So actually, AFAIK, keeping the car plugged in and not driven will NOT charge the battery and will lead to it potentially being discharged. Unfortunately, the car will only charge the 12V battery every so often when it is NOT plugged into the EVSE, so actually it's a catch 22.

Thanks Nissan!

The 12v battery gets charged every time a charge cycle is started. The charging algorithm is not great, so it does not get a full charge like it would from an external 12v battery charger. If the car is charged every day, it should keep the 12v battery at an acceptable level. If the car is left plugged in, but does not charge every day, the 12v battery can be depleted by the car regularly checking to confirm that the external power cord is still attached. If the car is not plugged in, and not driven regularly, the 12v battery is periodically checked and charged, if needed, using power from the traction battery (provided the charge level is not too low).

The problem with the above is that the car makes no effort to FULLY charge the 12 volt battery even under optimum conditions. It either charges for a fixed amount of time or to a too-low voltage. As a result the 12 volt battery in a pre 2014 will be chronically undercharged unless you use an external charger once or twice a week...
