DCM fuse

Ok, I think I'm understanding now. I'm sure you know but key fobs are susceptible to MITM attacks so keys only to unlock!

I would also say you are more likely to be affected by attacks from using the Internet than any car based attacks. So I would highly recommend never using the Internet as well. Good luck out there.

 

Key fob attacks are precisely why many people buy faraday bags or boxes to put their keys in when they're home. It's fairly trivial to defend against.

I don't know how many times I have to say this in the same thread for people to understand, so I'll try to make this so incredibly clear that there isn't room for misinterpretation anymore. A hack of one of your internet connected devices, such as your computer, has reversible consequences. Exposure of private data will not kill you. The reason you should be more worried about your car being hacked is that it can literally end your fucking life. I've already explained this a few times so I don't know how the fuck this is still so hard to understand. I feel like you have to be literally dumb to think your computer getting hacked is worse than your car getting hacked when you're going 90mph on the freeway.

 

Statistics have entered the conversation. Can you link me to a single instance where an accident was caused by hackers in the wild? And better yet, one that caused death?

 

This thread started with wanting information on which fuse to pull, in order to prohibit transmitting personal data, right? I think your concerns are best addressed with the Chief Engineer for the Tacoma.

 

I'm old enough to remember when worrying about getting cancer was a thing.

 

What is this supposed to mean? All I need to know is if the same thing that worked in the '23 works in the '24. Anyone who owns one could say... I don't need to talk to the "Chief Engineer"

 

Maybe wrap the whole truck in tinfoil? Should keep the aliens out also

 

Seeing as how Toyota has completely revamped their electrical/data architecture in new models, I'm going to say it's unlikely that the same thing from a 3rd gen works on a 4th gen in the same manner.

I took like to disconnect telematics in our vehicles. Been doing it for about 8 years now, starting with my 2016 VW GTI, and now my new Titan and 2020 Corolla HB.... All of these vehicles can be disabled the same way: disconnect the wifi and cellular antennas. So far, the aforementioned vehicles now just think they are in a no service area.

Note that our 2020 Corolla has the older system than your new Tacoma.

If manufacturers start getting wise to disconnected antennas, they may make the system notice and shut down, or something. Currently, no harm that I've seen.

On my Titan, the navigation still functions because I left the GPS antenna connected. I do occasionally get a notification during startup that data is waiting to be transferred, but that only happens once every 2 weeks or so.

BTW, all my vehicles used what look like the exact same connectors, looks like the industry standardized them.

 

The tinfoil hat memes are tired. We are only a few years away from a time when authorities will be able to geofence certain places, then purchase the data from data brokers (without a warrant) to see who's been there. They can already use the ubiquitous Flock cameras to build a history of where you have been, and they can extrapolate your path across town or even across a state.

Yeah, yeah, most of us have nothing to hide so there is nothing to be afraid of.

But what if you, for example, eat at a restaurant in Colorado that shares a parking lot with a dispensary? Your phone location (or your location that is phoned home by your truck without your knowledge) could tattle on you. We're close to a time where law enforcement in one state will be able to purchase the location data of people who have visited certain geofenced areas in other states, then set the automatic license plate readers on highway patrol vehicles just inside the person's home state border to alert on the vehicle so they can pull it over for a little look-see.

Another situation that could arise is if you need to travel if certain types of healthcare are not available in your home state. In that case you can leave cell phones at home, park away from the medical office and walk in (so your plate isn't seen by recorded by people who monitor the parking lot) but should have a full understanding of the data the vehicle is sending out, disabling the system if necessary (or maybe just taking a 2016ish or earlier vehicle).

The first time someone gets busted with information gained in this manner, it is going to cause an absolute firestorm. I am not trying to be political with this post, just making sure everyone understands the full implications of privacy and why many folks are starting to get a little concerned about it.

Instead of blasting everything out by default, not knowing how it's being used and where it's going, we should strive to restrict everything to the maximum by default and then only allow the minimum amount of data to be collected.

 

I'm curious how you plan to fix it.

 

The truck or the surveillance society?

The truck is easy for now, I disabled it all on the Toyota Privacy Portal. But I'm sure soon they will require the DCM to be active or the truck will go into limp mode (like when a diesel runs out of DEF)

To me it's mostly important that everyone understands what is happening and what is occurring, then you can conduct yourself accordingly if needed

 

DCM = Dichloromethane

 

The surveillance. You seem really plugged in, but don't care to do anything about it. Nobody seems to care. I kinda wonder if the great reset is going to happen after I die.

 

Not really... you can use a VPN, lockdown/restrict those devices with software/firewalls, completely turn them off, not bring them, not have a Google account, etc. The DCM, on the other hand, is always powered on and has its own cellular connection and an eSIM that you can't remove. It has a battery and memory so it can store events as they happen (even if there is no cell service) then it will send the archived data out once you come back to the city. Without knowing fully how it works, or what it reports and to whom, it's best to behave like it's a little snitch.

I mean, I have thoughts that aren't allowed on this forum so I'm being intentionally vague. But, I mean, the surveillance is here, and I assume that we will never have privacy protections like they have in the EU because too many entities make too much money off of it at every step. The best you can do is be informed and be aware of how the information is used, how it could be transmitted and how it could be used, and conduct yourself accordingly.

 

Conspiracy theories aside....

A more practical point.....

What if manufacturers begin putting key vehicle functions on the cloud? Like HVAC, cruise, driver assist, etc...
And someone like me, just wants to not have my vehicle tracked everywhere, for my own reasons... I disconnect my telematics antennas and lose those cloud based functions?

A few car manufacturers already are trying to put options on subscription, which would require your car to be connected to authorize those options to work.

I just don't like the premise of the expensive vehicle I own, and should be my own private property, actually isn't private....

Even without disconnecting telematics, some of these newer vehicles could lose some subscription functions when the cloud servers go down.

Ok for a smartphone, not ok for a vehicle that costs half of someone's yearly salary....
