Sounds like your 12v battery got cold last night. Might be time for replacement. If you delete all Carwings info and sign in again and it starts working, it's the 12v battery being low.
...or it may just be that Nissan's system was down. It is not "up" all the time!
I get that you had 12v problems, but you need to stop telling folks to replace their 12v battery every time NissanConnect doesn't work.
Yes: it's a good idea to keep an eye on voltages, but real 12v problems will manifest themselves in other ways (like your car won't start).
I thought I remember reading back in december/early January that people were having this issue after the upgrade but I don't remember how far back it was. Just wondering if anyone was experiencing this and had a solution.

I'd love to hear if anyone had daily operation of their new 3G unit for more than a month straight.
I have replaced 20-30 of these units and the failure rate seems to be 100%. They usually work for 1-4 weeks and then stop working. I force the TCU activation team to force the registration on the spot when I call in the replacement unit. All of mine leave the dealership working/signed in. The problem is that after a few weeks they come back not working. I replaced the 12 v battery on one, but it then only worked for 4 days after that.

Email me if yours has worked for a month straight without the ID numbers turning to asterisks: runforwwp@yahoo.com
I need to find a solution to this. I have already read all 60 pages of this thread :shock:

A) People say over and over that "oh Nissan's servers are down..." and then I update my Carwings and it works immediately.

B) I don't tell people to replace their battery, I tell them to do a test and then I say if the test passes then I recommend they check or replace their 12v battery.

C) How many people's Carwings have you fixed?

My Carwings has worked 100% since I installed a new 12v battery 22 days ago.

If you install these for a living, then you know the TCU is only one part in the NissanConnect signal chain. My 3G modem has been working for almost 3 months now; I don't think the "service" has ever worked every day for a month straight...and that goes for the (old) 2G modem as well as the 3G modem.

Not quite a "ghost." I mean 24/7 they are not working. The customers usually come in complaining about it after it has stopped working for 2 weeks straight. Being on the other side of this, I get to see all of them coming back with problems after a few weeks. All of the TCU info goes to ***** permanently.

I have purposely not upgraded my 2012 Leaf to 3G until the Nissan engineers come up with an amendment to the recall.
On the ones that the customers have called consumer affairs, they are just telling the customers to come in for us to do a parts warranty on their unit, but that only ends up being a temporary fix. The problem is that the TCU units are going into standby permanently. When I check the history data on them, they typically have been in standby for 2 weeks already.
Unfortunately we cannot tell customers to disconnect their batteries once in awhile as the permanent fix. Haha.

Your last sentence suggests a design issue/flaw not related to 12v issues. If the TCU is "timing out", then a software fix is possible; I don't consider "reset" (cycling power) a hardware issue in this day and age.
Bottom line: if you're right about the root cause, then I hope there's an amendment/recall that would result in a permanent fix across the board.

I have found that I can reset the TCU just by going into Carwings settings and "deleting all Carwings settings," then logging in with the ID and PW again, no reset needed. That has helped a few people in this thread and on facebook that I've talked to.

Like I said mine has been working 100% except for a few times when I purposefully took my voltage down to the low 12v range in which case it stopped responding (then I reset my Carwings). I will let you know in another week when I reach 30 days. I also noticed when pinging the car, relays or contactors will click on an off, normal enough, except that they are accompanied by another .5v or so voltage drop on the 12v system, that is on my car with a healthy 12v battery. The very act of pinging the car could send the 12v voltage down below 12v on a weak battery.

Standby mode is a good way to describe it as the car can still update charging stations, navigation, etc. but the apps and websites don't work...until you reset it. I'm very curious as what you describe sounds like a total hardware failure, I guess I will see in 7-10 more days as you've decided 30 days is the magic number.

Also unrelated, Leaf Manager has been down for about 36 hours. Nissanconnect EV still works through the website and the app but Leaf Manager is down. Hopefully not long :( I used the app to start my CC just about 2 hours ago.


Edit: Actually, I take that back. My TCU was installed by the dealer on 1/16/17 so my unit has been in my car for over a month now. I was counting 22 days from when I replaced my 12v lead acid battery with a LifePO4 litium battery that has never gone below 13v. And full disclosure I have noticed sometimes on Friday nights into Saturday afternoon my car will not respond and resetting doesn't help, I attribute that to Nissan but have no proof.

Is there anything on the owner side that can be done to look at the TCU history or see if the unit is in standby mode? My unit worked a couple hours at the dealer then was never heard from again. Lost in space. :mrgreen:

I had my TCU updated on my 2012 LEAF on 2/10. it seemed to work until 2/13 -then stopped.
I will also note they did the P3227 update (or whatever the chargebar 'battery warranty' update is...) at the same time.

I'm also seeing the car light up the EV warning light each morning after overnight charge.

I alos have the following codes:
P312A 00C0 EV/HEV Comm Error EVC-208
P3131 00C0 EV/HEV System Shutoff Timeout EVC-220
P31C2 00C0 EV/HEV TCU EVC-273
U1000 000b TCU CAN Comm Circuit


The car does update local charging stations and will sign in etc. I just get no email notifications and have no webpage/app functionality (charge status, charge initiate, Climate control start/stop etc)

I spent 2.5 hrs at the dealer today. All I got was a cup of coffee and car wash.

I'm pretty sure my 12V battery is OK. It's less than 2yr old. -- LeafSpy pro reported it at 12.76 v at the time my car finished charging (and the BT link shut down -- but I haven't load tested it...

I will try to read the 60 pages of this thread to catch up, but I thought I'd put my info out there incase it helps provide any info to anyone else.
