Mobile operators to shut down 3G networks in 2022

[mcmancuso]

After doing a TON of research on this for my 2013 leaf SV, it appears that the newest part, superseding the older ones is 283B0-3NF2B, the FCC ID on this (from looking up other parts with the same lookup code - 283B0P) is N7NSL8080, this contains the Sierra wireless SL8080 modem, which supports 4G bands. The pricing is the same as the previous model, and they both show compatibility with the 2013-2015 leaf SL/SV. It looks like if you request this part number for the upgrade, you should be in good shape for 4G from everything I can see about the chip it uses.

This is the part with the same lookup code where I was able to see the FCC ID:



Here's the official leaf part, kinda hard to read, but it's the same FCC ID:

Unfortunately, it looks like there's a revision C that I don't have the PDF for. But, https://www.aboutautomobile.com/Technic ... cal-System was a hit that came up that has stuff like this:

Thanks for the research. This still requires the dealer to configure with Consult to work, right? I'd be very interested in hearing of someone successfully doing this.

Incidentally, the linked part gives me a "Unable to verify part fitment for your vehicle" message for my 2017 SV (searched by VIN). Seems like there are a bunch of TCU variants.

AT&T appears to have removed 3G from the tower(s) nearest my house in the last week, so no more telematics from that location. I'm getting random notifications about the battery being fully charged, presumably where the car picks up a signal.

I just spoke with my dealer here in Longmont, CO, and was told that the service bulletin that replaces 2G with 3G has expired (service comm ID PC449). Has anyone else had the same response lately?

At least 4G likely won't go away fast. 5G is built on top of 4G.... so they both have to work.

The page for the app seems to say with certainty that only 2018 and newer Leafs will be able to use it.

"Please see important information below on 3G cellular network discontinuation impacting MY11-17 LEAF vehicles***.

***The NissanConnect Services telematics program will be affected by AT&T’s decision to discontinue its 3G cellular network. On February 22, 2022, all Nissan vehicles equipped with telematics hardware compatible for use with the 3G cellular network will be unable to connect to the 3G network and unable to access the NissanConnect Services features. Clients having purchased a Nissan vehicle with this type of hardware must have enrolled in NissanConnect Services prior to June 1, 2021 to activate the service to receive access through February 22, 2022 (access is subject to cellular network availability and coverage limitations).

Do what I did: replace the (Nissan) TCU with a (3rd party) OVMS module (https://www.openvehicles.com/). You can search the forum for more info/threads on OVMS if interested. Note: the OVMS 4G option/module is set to be released in December.

@Stanton,

What would my time/money investment be on that?

I'd like to keep the capability, but it's also not really a deal breaker since I can work from home for the foreseeable future, so I'm not as concerned about being able to remotely activate the defrost in the winter and the car stays under a 3 sided carport under part of the building at home.

Mostly I'm worried about how much time it would take me since I've never had a car with a TCU or even any sort of built in navigation/radio system before this one. I'm juggling work, law school, condo association, and kids so I really don't want to spend over an hour in it. Is it pretty much plug and play with the wiring/TCU unit?

I was hoping for some new information here. I got the email from Nissan this morning saying basically we are SOL for service. I paid the $200 for the upgrade from 2G to 3G several years ago. It would be nice if they offered an upgrade to fix it this time around.

@Stanton,

I'm also interested in OVMS, but the web site doesn't seem to give any technical details at all. If you hadn't mentioned it, I would assume that it was a Tesla Roadster only product.

Any information you can share specific to using OVMS for a leaf? Is there an additional subscription fee, or do you need to provide a SIM to enable cellular data?

I have a 2017 SV and will likely be SOL, as many others have mentioned.
