4G Modem Disabling Instructions:

[Bikeman315]

Hey, while I'm thinking of it, does your GT have a spin on oil filter?

Yup, FL-500-S

Wi-Fi can be turned off in settings. Then you should be good to go.

Does it mean that your car will store your driving data and then upload it to Ford once it connects to your home Wi-Fi?

If you turn off the Wi-Fi it will not connect to your home system.

You're not paying for the LTE/4G service your car is connecting to, but someone is. This implies the value of the data captured is high enough to warrant adding the modem and having an always-on connection. Therefore it would be very safe to presume the computer would use every opportunity given to it to make a connection and phone home, and they were probably already doing this when connecting to Wi-Fi before they started incorporating the modems. I'd also presume the data would be sent through the Ford Pass app when you are connected to the car via Bluetooth.

I don't think it was ever positively proven that pulling the fuse or diabling the 4G modem will prevent data transmission via wifi.

I'm not going to guinea pig this one because I'm 99.999999999% certain we already know the answer.

The question is, how would the mustang have the security key for your Wi-Fi network. Every device must have a key to connect to your local or any Wi-Fi network.


"G LTE mobile coverage areas of the nation’s four largest mobile wireless carriers: AT&T Mobility, T-Mobile, UScellular, and Verizon."

If you have not paired the cell phone with the car, snooping is avoided.

You can use the phone navigation without paring it.

Seems without one of the methods active above, one will be riding free of unwanted snooping.

I am sure most have noticed the software updates, all want to connect, sync all the devices ............. SO THEY CAN SHARE what BS.

Isolation is the best firewall, each device having its own preferences login/pw. Might be worth the trouble.

Without the modem powered it's like not having an engine, in the car it ain't gona go.

I've not looked or seen the modem so I don't know if the input is a coaxial cable or not. It should be a shielded type of wire for sure, pull that and you will kill the Wi-Fi.

Some wifi networks are open. This is the problem. It was discussed before that ET will find whatever connection it can find to phone home. If anyone wants to test this, the process is simple. Locate your modem in the left rear trunk area (behind all the plastic trunk liners) and pull the modem harness. If your car is in reception of an open wifi network, attempt a fordpass connection.

It is believed the 4g modem and wifi module are not the same. If you disable the 4g modem, the wifi module isn't necessarily offline.

Test it. I would do it, but I long since cancelled my Ford pass and deactivated it all.

Yes, without the password it will not be able to connect. I have not specifically sought it ought and tested, but I have never noticed any transmissions with Wi-Fi turned off. If it were turned on, I wonder if it would attempt to connect to public networks...

My view of a public network is, at the donut shop. You ask the counter what is the name of the network & then get a login donuts/ pw eatmoredonunts.

I don't think anyone can just walk into a public place and sign on to the internet, and go surf. Without a login/pw

A cell works like what you maybe think is a public network. But that is cause there are cell towers, your cell being a registered device of a carrier allows web access. Wi-Fi networks are different, need user/pw for access.

While not necessarily applicable in this case that isn't entirely true anymore. There are sub network sharing devices out there that are beginning to blur that line. Comcast and Amazon both have devices that will allow other "partner" devices to connect and share bandwidth from their connected networks. These BS features are on by default so even if you turn them off Joe Schmoe nextdoor has his connecting to anybody that comes along.

If wrong, correct me this reads as if Amazon sniffing traffic over Concast. Will be able to load a browser or an inbox with ads?

More direct than the algorithm?

Hes not saying Comcast and Amazon are working together he's using both companies as an example.

Yes, that is correct. Both are examples of products that open an access point for traffic through your network that you don't control or even know are there.

That's certain. The 4G modern is in the trunk, below the left tail light. The wi-fi module is integrated in the APIM (the Sync unit).

Since this is so old and I had to refresh my own memory, here are a couple reminders:

That top picture shows two orange circles where a guy could look (from underneath the car) to find a couple of antennas. I don't remember if these are Wi-Fi or 4G/LTE antennas. There is an antenna in the rear package tray that is 100% a 4G/LTE antenna (you can tell what sort of transmission/data is broadcast by the sound the RF meter makes) The two antennas in the trunk need to be identified and checked. They are shown in the diagram in the link below to be in a different location from where I have circled. I will check and test all this this weekend.

Pulling the fuse disables item #6 from that diagram, referred to in various manuals/diagrams as modem, TCU, telematics, etc. and contains at least the 4G/LTE modem as there is a sticker with an IMEI printed on it.

Item #5 is the 4G/LTE antenna as confirmed by my RF meter spiking (and audibly confirming 4G/LTE) in the center of the rear package tray.

Items #8 (splitter) and #9 (antennas) are confusing, because they are labeled "cellular" but I want to make it very clear that I remember these antennas only transmitted when I turned on the in-car hotspot. I do not remember if they were transmitting 4G/LTE or Wi-Fi, but I will check again.

I will attempt this weekend to isolate where the Wi-Fi transmissions come from.
