question i have is will the BCM throw faults if disco'd ?

Possibly as the software has different options enabled between trims. We see this in the head unit, a/c and gauge cluster.

Head unit needs it for maps. If the unit is disco'd and the HU calls for it, the BCM will issue a fault of it not working.

If you take off the antennas then it will just see bad signal. Of course, again, it may get a signal here and there. Albeit a weak one, but enough to get those worried about it.

After disconnecting GSM antenna, have the connector shorted. That will prevent any communication with host system. This should be sufficient. It is also possible that telematics controller has SIM card in it. Removing that will also make calling host system impossible.

and, just to show how that is used, if you have an insurance company who wants to offer you lower rates by showing you follow the rules, they will track your vehicle using that type of thing.

back a number of years, i ahd a 93 chevy truck and had state farm insurance. they offered a discount for following the speed rules and not hot rodding off the line or late braking. i asked how do they know if you do that? the person on the phone said all new cars can be tracked by giving them the vin so they can see how fast you take off from the light or if you slam on the brakes last minute, or of course, if you are speeding. since my truck was older, they wanted to send me a little deal to plug into the odb (or maybe it was the cigarette lighter, that would allow them to track my driving.

i passed on the deal but you see how companies track you using your vehicles built in systems.

The auto manufacturers stopped using SIM cards some time ago, the sim is not something you can remove on these things. Ive opened several from other manufacturers. As I mentioned previously, we only need to disconnect the cell antenna connector, not the GPS. And we can test if this is killing data transmission by using the Nissan connect app.

Yes, never use an obd dongle for insurance discounts. It gives them too much info. Instead I use an old phone with the app, this way I control when it collects info, and the phone has no connection to the vehicle so it can’t collect anything from the vehicle, it can only use the gps in the phone to determine speed and distances…

 

[busemans]

good idea on the old phone

 

[caddisguy]

Has anyone figured out a solution to this and if there is a "how to" (ie: disconnecting the cell antenna connector) for preventing the vehicle from transmitting my location and driving data to Nissan and the various partners and agencies they share it with?

I don't want big brother knowing my secret mountain bunker or my "carbon score" or whatever they decide to do with the data. And in theory, could these trucks be remotely disabled? They can push software updates right?

They can remote start, unlock, locate. So yes, it's possible. For you, only possible if you pay for it.

Do you know if there is a way to prevent all the data transmission in both directions. Ideally looking for a how-to if anyone has every successfully done this.

Have you located the vehicles sim card? you may can just remove this. of course that will disable a lot of things, like maps and any remote ability but this is the point.
removing antenna will give weaker signal, but like a phone it will just boost the signal output and like a phone does not need a big antenna anyway.
you are the product. this is not a feature saved for luxury vehciles, all vehicles have people and people are the product. data is more valuable than the car. all the data is encrypted. companies never talk about it. is worse than your phone for privacy, way worse than the dummies calling you tinfoil can or ever will imagine.

could you tell us all where that SIM card is located please and the 10 digit nissan pn#......

these are not things automakers want you to know, and im surprised the see ey aey has not chimed in telling us it does not exist and tinfoil hats and all that, but no, I have not explored around to find it yet. official comment is you are all crazy and nobody wants your data and this is stupid and why would anyone want to know anything about you and why do you care who knows everything you do, say and where you go and how fast and how often...

Looks like a fuse pull will not be possible. It appears the TCUI is connected to multiple fuses. One of them is (Fuse 6 / 10A) that is shared with multiple things like CAN gateway, TPMS, DIff lock(if so equipped)..

I think our best approach is to knock out data transmission from the TCU.

Look at greyfox pictures above from the TCU on eBay, I see two obvious antenna connectors, blue and purple. One of these is GPS, one is GSM (cellular). Looking at the wiring diagram, it looks like it is a one piece connector labeled "M150". We don't want to pull the GPS portion, or we loose navigation ability using GPS. We want to disconnect 1 & 2 of M150 which goes to the TEL ANT. I'm fairly certain if you disconnect that, the TCU will lose the ability to phone home... Effectively cutting off big brother.

Mind you, our less luxurious models don't have the same hardware

Crutfields photos were taken with a potato, so it's really difficult to make out the cables and connectors with the dash removed. I'd like to think that if you have that removed, you've have access to the antenna cable that runs through there. Ideally, you unplug the connector (M150) if it's accessible. A more destructive method is to simply snip the cable there. The antenna itself looks like a major problem to remove; dash needs to come out, ac ducts need to come out, trim needs to come out, etc just to have access to the screws that keep it in place.

So is this diagram showing that the cell and gps connected to the TCU are actually under the dash and not in the sharkfin antenna on top?

Would that mean the sharkfin has XM and AM/FM?

I'm trying to figure out how to physically delete any telemetry that doesn't stay local as well as XM. That would mean any GSM and all GPS. Potentially Wifi and technically bluetooth but i'm not gonna go that far right now.

I would just make a little tin foil hat and glue it over your antenna.

FWIW, I saw a news story the other day and they mentioned you can look-up what data a particular car company supposedly collects and does with it. I don't know how legit the info is but, here's what it says about Nissan:

Ran across this article today. More intrusive (and unconstitutional) gov't over reach. Going forward, owners of newer vehicles that value their freedoms will need to disable this crap.

More Intrusive BS, for your protection, of course
