I'd suggest logging what the Tesla is trying to connect to/ping on the internet and use the Pi's server to trick it into meeting those requirements. Might be a way to get around the teatherd phone problem.
I gave it a quick try this afternoon, and found that tcpdump doesn't work when the usb0 interface is active. It's possible that I had a network misconfiguration (the android phone DHCP issues addresses on the subnet that I had just happened to choose for my own WiFi network), and didn't realize this at first. I'll investigate more later. I agree that a replay attack may work well.
just take notebook - up the wifi AP on it, try to connect the car with running tcpdump. R-PI is ok for the task too, you just have to have some display, that is the reason to use a notebook. They might use robust ways to determine if it is real internet or not (ssl connection to tesla servers, or any known server, but I doubt they do)
+freakaefari if it the case, at least you will be able to see that it is the case, and probably it might be the case after next update after that video )) I doubt for the following reason what if the servers are not accessible, so then the internet is gone for all cars? Most likely it pings or tries to resolve some domain names (firmware upgrade domains or something like that)
I've watched most of your videos and have been for a couple years now. You are by far one of the most intelligent and capable channels that we have to watch. Thank you for all the great work and inspiration.
Very cool! I've been getting into car hacking lately as well. I'm hoping to build some cool data logging digital gauges. I should mention that linux has built in CAN bus support in the kernel that treats CAN as a network interface device. There is a suite of tools that can be used to display can bus information. cansniffer, canlogserver, candump, cangen.. One of the most useful is the ability in cansniffer to display ONLY values that have recently changed. It really helps with reverse engineering because you can try messing with things and it will only display the values related to the thing that you're messing with.
You have that gift of being able to explain complex projects in a manner that even cave dwellers like myself can understand. Nice work, please keep it up, and thanks.
DigitalYojimbo I have a Tek 466 and did single takes then writing down the timings to figure out a bus issue from an AD converter, good times... I wish I could afford a nice scope
A Controller Area Network (CAN bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles, but is also used in many other contexts.
I think I've only ever understood about 20% of what you've ever talked about... I don't even know why I watch, but I just find it relaxing and the stuff you do looks cool... lol
With enough development work you can create an advanced diagnostic tool for your tesla. Being able to log and graph things that are not available on the head unit normally is a huge help.
You are a hero Ben, congratulations on the Model S! (Saving up for one myself) The motor controller uses large and well heatsinked shunts for phase current measurement, if you decrease the shunt resistance, or intercept the on-shunt amplified signal and scale it down by some amount, the motor controller will drive proportionally higher phase currents relative to the amount of shunt signal attenuation. It may require re-scaling the battery current measurement proportionally as well depending on a number of factors. I don't think it will impact traction control functionality or launch mode.
I miss making videos too! Even though I'm really busy with work these days, I feel like I need to up my motivation game. I used to be more productive in the past despite the work load. Got any motivation tricks?
Applied Science heres a motivation, you bring happiness to many people with your videos including me. Happiness is the greatest gift you can give someone, thrive on that.
Applied Science. Ummm... Cannabis and good music works great for me, but I am a self employed artisan. I don't require the critical thinking part of the brain vs someone such as yourself lol. Is there any new tools or equipment that you want to acquire? New experiments always seem to get you back in the shop for video content:)
what I dont understand is why the car doesnt already have a cool readout like this already. its like engineers forget about the nerds like us that DO want to see this data and find it so fascinating
programming expenses, UI organization. They try to keep it simple for another half of owners(but let's be real, for 95% of them, and 99.99% in the possible future)
Very cool Ben it reminds me of my efforts to RE the BMW I-bus and K-bus back in the day although all I was going for was making a button on the steering wheel roll down all the windows. I have also used a similar webkit websockets browser trick to get realtime apps running on the IP phones at work (Polycom VVX). By the way you might consider testing using noVNC to display the rpi console in the browser. If you run x11vnc to mirror the local display to the vnc client you can use a USB keyboard directly on the pi and you have the display in the car's browser.
I suppose one solution to the attack vector would be to remove the tx pin trace on the MCP can transceiver that way the device would only ever be able to listen to CAN data and not reply. Great video!
Great to see some new stuff! I totally agree with the text message. Even if I love network connected technology, I'm really against all the "cloud stuff" and always keep stuff like this locally and WAN disconnected. Two ideas: you could run a simple firewall on the rPi, that only allows access from the cars IP address. A better solution would be to use the rPi to create a network using a USB WiFi card. This should be pretty simple to do and you wouldn't be at the risk being kidnapped in the middle of a road trip ;)
I love the hack, so much potential! Great job done there! I think You could easly persuade car into connecting to `offline` hotspot by just logging all packets on the RPi by the time the car tries to connect into it. There are really not to many options here, they could be using some ICMP communication to just check for particular IP network presence or checking some static response from known service (maybe even just checking public DNS) . You could just log these packets and replay them automatically as needed. I dont belive they would have gone into so much effort that they using any advanced CRC just for that simple task, so this approach should be really effective. Would even love to help You with that - however I wont buy tesla just for that ;) Good luck!
This is pretty cool, I'm using the same hat in my own car to log info like mpg, trip distance, and DTCs, and send them back to a mobile app on my phone.
I've been thinking about the framegrabber and digital control project for the SEM. I'm planning to use the Teensy 3.6, and was hoping the USB high-speed port would be working soon in client mode, but it could be some time yet. Someone sent me some code to experiment with, so I should probably hunker down and just start doing it.
Hey - I'd love to see a video on reverse engineering the charge cable. Specifically what communication occurs between the car and the charger both during charging but also even what the signal looks like to open the charge door when transmitted from the button on the charge cable? Love the channel.
Since you are only listening to the CAN bus, you coult desolder the TX-Enable pin of the CAN-Bus tranceiver on the Pi shield. Thatway, even if the Pi gets compromised the attacker would not be able to send data to the car. So the security risk gets quite a bit smaller.
If you wanted to get really fancy, you could even run the signal through an opto-isolator. The Pi wouldn't be electrically connected to the CAN bus at all.
For the security concerns, if you are fine only snooping the data passing by and don't plan on transmitting anything (and frankly you shouldn't be anyway, since I'm not so positive the internal can network has been properly fuzz tested) you can just physically unsolder the tx pin between the raspberry and the transceiver, this means that even if an attacker fully owns the raspberry it can only read the data on the bus and it can't sneak anything in, you will lose the ability to specifically request data, but that is the small price you have to pay
This is the first video I've come across where the OP uses a lab/bench scope in automotive diagnosis ! Are there any others on TH-cam or other sites? And many thanks for sharing this content.
So cool. I'm sitting here trying to decide how one gets from knowing basically nothing to knowing how to do what you've done here. It's really impressive to an ignorant fool like me. Thanks for sharing. Getting data out and describing it is interesting, but what about going the other way? Seems like one could write and run their own programs: silly horn music or headlight sequences... who knows. Anyways, very cool.
This channel is absolutely great, by far my favourite in YT!! But lately, the frequency of uploaded videos is low. Do you guys know any other channel with similar content?
I might be able to help you out with what is known as a CAN database. In the automotive industry these database files are often referred to as DBC files. DBC comes from Vector Informatika. There are some good CAN reverse engineering tools on the market that will show you live CAN data and highlight just the values that are changing so you can sort of work out & create your own DBCs. My ISO14229 stack is running in many US vehicles. ISO14229 is the diagnostics protocol that runs on top of CAN sort of like HTML on top of TCP/IP.
Nice job man! I've never wanted a Tesla as much as I do now! I imagine you've already been talking to Samy Kamkar about this project? (He is already a fan of yours.) I was just thinking that, if you knew what the car was pinging in order to determine if there is an internet connection, you could reroute that traffic to a local IP like you did with your server. I guess if it was more of a complex query than a simple ping, that would be more difficult, but I would think it's worth looking into. Please keep us updated on this project! And talk to Samy if you haven't already! :-)
about the attack risk mentioned, It may be possible to disconnect the can tx pin from the pi side, then the module can only listen to the bus but cannot send anything
considering security against hacking, your raspberry pi don't need to be really connected to the internet, the just needs to think it is. so you can wireshar the packets passing through the pi, and see how the car is testing connectivity, then you can make a script on the py that replays the packets you grabbed every time the car tries to detect internet connection.
You could still connect the wires to a Bluetooth obd adapter and use torque to find the pid and log it through your phone. I would be interested to see if you could send an odb command though, the doors are controlled through one of the CAN buses.
The OBD2 port is required by law to be there and have certain information in it. I believe it is required to be within 12 inches of the steering column.
Great video!! I was thinking you could temporally connect the Pi to Ethernet on your wired network to do some packet capturing and see how the car is checking for an internet connection. Once you know that, should be able to tell the car what it wants to hear from the Pi and get this working off the web. This is basically what I had to do with my blue-ray player a few years back when Sony servers went off line and the blue ray would not play Netflix without being able to phone home first.
cool man you are awsome I use to work with CAN and CANOpen / KWP2000 nets since 15 years new ... I have no tesla under elbow (no money) but if I can help you with differents protocols it will be a pleasure ... anyway congratulations and keep going !!
You could log it to a timeseries database like influxdb on the rpi and use something like grafana as frontend for your graph visualisation... not sure if the rpi3 is fast enough for that, but you could give it a shot...
I didn't think it was possible to have all of my favorite things in one video: Raspberry Pi, CANbus, Tesla cars, Node.js, and websockets 😮❤
awesomeguy2802
yes
all in one video
unbelievable,
applied science 👍👍
what a time to be alive
start by getting respberry pi and learning react.js
awesomeguy2802 don't forget a nice oscilloscope
I can't believe that anyone would list CANbus as one of their favourite things

They might use robust ways to determine if it is real internet or not (ssl connection to tesla servers, or any known server, but I doubt they do)
i'm quite positive the car will try to setup a secure connection to Tesla servers... so spoofing that with the RPi will not be possible...
+freakaefari
if it the case, at least you will be able to see that it is the case, and probably it might be the case after next update after that video ))
I doubt for the following reason what if the servers are not accessible, so then the internet is gone for all cars?
Most likely it pings or tries to resolve some domain names (firmware upgrade domains or something like that)
good point.
well, only 1 way to find out, i guess...
I've watched most of your videos and have been for a couple years now. You are by far one of the most intelligent and capable channels that we have to watch. Thank you for all the great work and inspiration.
Very cool! I've been getting into car hacking lately as well. I'm hoping to build some cool data logging digital gauges.
I should mention that linux has built in CAN bus support in the kernel that treats CAN as a network interface device.
There is a suite of tools that can be used to display can bus information. cansniffer, canlogserver, candump, cangen..
One of the most useful is the ability in cansniffer to display ONLY values that have recently changed. It really helps with reverse engineering because you can try messing with things and it will only display the values related to the thing that you're messing with.
ryan edge thanks for sharing this information 😊😊😊😊
That's really useful. Thank you.
Hmm, DeLoreans, old trucks and Telsas (and an MDO4000)... ...Ben's garage is a great place to be!
:) For both test equipment and cars, both new high-tech and old/quirky is a lot of fun.
You have that gift of being able to explain complex projects in a manner that even cave dwellers like myself can understand. Nice work, please keep it up, and thanks.
That's one very expensive digital scope you've got there.
Spoif Tektronix ? I prefer agilent or keysight.
+DigitalYojimbo Personally, I prefer Agilent too.
I bought myself a hameg ... made in western germany.
Still better than no scope at all.
Fatalcreator rohde schwarz ? or hameg ? probably hameg by the west German reference. classic, but good luck trying analyze logic with that ;)
DigitalYojimbo I have a Tek 466 and did single takes then writing down the timings to figure out a bus issue from an AD converter, good times... I wish I could afford a nice scope

Would LOVE to see a follow up video to this to see all the progress you’ve made!
I bet Nicolas Tesla would have enjoyed watching all your projects, including this one :-)
After seen this video on my recommendations, I had to subscribe without even looking on older videos! Amazing video!
With enough development work you can create an advanced diagnostic tool for your tesla. Being able to log and graph things that are not available on the head unit normally is a huge help.
You had me at "ODB2" you prankster you.
I was getting a little suspicious at "the number of amps being pulled out of the battery pack" though
you are the coolest nerd in youtube
I'll never understand how anyone could thumbs down videos like this. Keep up the super cool science stuff!
You are a hero Ben, congratulations on the Model S!

Been missing your videos
I miss making videos too! Even though I'm really busy with work these days, I feel like I need to up my motivation game. I used to be more productive in the past despite the work load. Got any motivation tricks?
Applied Science well you make us happier and less dumb
Anything cool at work that you might be able to talk about? or film...
probably not, but it would be cool
Applied Science heres a motivation, you bring happiness to many people with your videos including me. Happiness is the greatest gift you can give someone, thrive on that.

11:40 - when your car ends up being less secure as a result of them trying to make it more secure. XD
holy moly where has this channel been all my life
Can I say that explaining to us how you setup your scope and went through the steps was brilliant👍
Sir, you are an awesome dude. I can build circuits and toy around with a scope, but I wish I had half of your knowledge. Thanks for the video..
what I dont understand is why the car doesnt already have a cool readout like this already. its like engineers forget about the nerds like us that DO want to see this data and find it so fascinating
yeah, any car with an lcd could do this. It would be nice if it could show you why the check engine light is on at least.
programming expenses, UI organization. They try to keep it simple for another half of owners(but let's be real, for 95% of them, and 99.99% in the possible future)
some morron will look on the screen instead of the street.
They don't want you staring at real-time data graphs while you drive. It is very likely a liability requirement set forth by Tesla, Inc. legal.
Wait until driverless cars are commonplace. Then you can stare and have nergasms at real-time graphs on the screen to your hearts content.
You are the most technological guy I ever met.
I can't deny, the "...a little magic..." thing really made me laugh.
You are an inspiration to tinkerers and engineers everywhere! I love your videos!
Ben there's only so many times I can rewatch your videos until you put out a new one Hahah
He's alive! feels like it's been ages since you're last vid
Finally a tesla driver who knows what he is talking of!!!
Wow, you have so many cool things!
Very cool Ben it reminds me of my efforts to RE the BMW I-bus and K-bus back in the day although all I was going for was making a button on the steering wheel roll down all the windows.

oh yeah. lovin the rain down here in LA too ;) "what to do on a rainy day" some fine work Ben. Thanks for sharing!!! ~Russ
rwg42985 what's up man? Get back into VBM research your getting off track that's what your followers wanna see.
Amazing work. I cannot wait for the follow up videos!
Nice scope. Reminds me of using an hp 1630d logic analyser with a 1k trace buffer. lol
Technology sure has come a long way in my life.
You have a beautiful brain Ben.
I suppose one solution to the attack vector would be to remove the tx pin trace on the MCP can transceiver that way the device would only ever be able to listen to CAN data and not reply. Great video!
OBD2, not ODB2! How dare you
I'm definitely offended
I've been saying it incorrectly for years! :0
You're not the only one. OBD = On-Board Diagnostic ;)
ODB is database drivers. Anybody who has ever worked with them and cars is mind poisoned on those terms haha
you good, on-doard-bionotics basically AI level robo-cyber-tech androids, known as ODB
I think ODB2 is Wu Tang Clan's new rapper.
Great to see some new stuff!

Why must you make me miss you so much!?!??!?!? (Overjoyed to see you posting!)
This is pretty cool, I'm using the same hat in my own car to log info like mpg, trip distance, and DTCs, and send them back to a mobile app on my phone.
Still waiting for the next video on this! Loved this one!
I use node.js on my Raspberry Pi's all the time! It's my favorite language :D
Made my day.
Still waiting for SEM upgrade.
I've been thinking about the framegrabber and digital control project for the SEM. I'm planning to use the Teensy 3.6, and was hoping the USB high-speed port would be working soon in client mode, but it could be some time yet.

Damn, that's one cool oscilloscope! I want one as my wedding gift

If you wanted to get really fancy, you could even run the signal through an opto-isolator. The Pi wouldn't be electrically connected to the CAN bus at all.
No wonder he hasn't been uploading many videos recently... he bought a Tesla!
COOL
That's a neat idea with websockets. Nice.
Cool, Always have been wanted to learn this. Tips on a good start to learn oscilloscope
This was so damn interesting. I can't wait to see what you do with this.
That's quite an awesome video! Love the thoughts and processes how to capture CAN bus data! Nice TEK Digital scope by the way!
Here so early!
Grant Thompson - "The King of Random" whoa!!
Get back to editing videos Grant
clickbait...
What are you doing here?! :o
go back to making dry ice chocolate sillicone proto-putty vacuum chamber liquid nitrogen clickbait videos
the price of that scope tho'
These are the men that we thank god are good and not super villians.
For safety, you could hardwire the CAN transceiver into recessive state. As long as you don't want to inject packages, you don't lose anything.
For the security concerns, if you are fine only snooping the data passing by and don't plan on transmitting anything (and frankly you shouldn't be anyway, since I'm not so positive the internal can network has been properly fuzz tested) you can just physically unsolder the tx pin between the raspberry and the transceiver, this means that even if an attacker fully owns the raspberry it can only read the data on the bus and it can't sneak anything in, you will lose the ability to specifically request data, but that is the small price you have to pay
Wow this is amazing! Please make another video about this topic, it is super interesting! :)
Thanks for the great videos. :-)
P.S. Love the hitchhikers guide reference.
This is the first video I've come across where the OP uses a lab/bench scope in automotive diagnosis !
Are there any others on TH-cam or other sites? And many thanks for sharing this content.
So cool. I'm sitting here trying to decide how one gets from knowing basically nothing to knowing how to do what you've done here. It's really impressive to an ignorant fool like me. Thanks for sharing.
Getting data out and describing it is interesting, but what about going the other way? Seems like one could write and run their own programs: silly horn music or headlight sequences... who knows.
Anyways, very cool.
Nice radio dude. It has visualizations and everything! I bet you heard that joke many times already :)
Excellent video as always, thanks Ben!
Ah man! That scope is dope!
this guy is genius
This content is always the best. You're the man!
You have a model S now! nice, and great video.
Great video! But I'm curious to see Tesla's reaction to this.
YES!
New video,
This is most welcome.
This channel is absolutely great, by far my favourite in YT!! But lately, the frequency of uploaded videos is low. Do you guys know any other channel with similar content?
Hey, that's a really cool way to combine many skills. Very nice. Very good videos.
OBDII =/= ODBII Glad to see another video.
Thank you for a very informative and concise explanation! You should make education videos.
Can't wait for your next video!

Old Dirty Bastard live and uncut! :P
I am new to CAN but I have a list of codes from my Model X. How do I decode the messages to get a value?
Thanks, this is amazing work. Well sleuthed, well executed, and well explained.
You should take a look at Grafana for the graphs in the Browser. It's very powerful for monitoring and works with different timeseries databases.
I might be able to help you out with what is known as a CAN database. In the automotive industry these database files are often referred to as DBC files. DBC comes from Vector Informatika. There are some good CAN reverse engineering tools on the market that will show you live CAN data and highlight just the values that are changing so you can sort of work out & create your own DBCs. My ISO14229 stack is running in many US vehicles. ISO14229 is the diagnostics protocol that runs on top of CAN sort of like HTML on top of TCP/IP.
This is amazing.
Some DefCon type of stuff man.
Ben, I had no idea you had a Model S. I've got a 2013 early (Vin less than 3300) S60.
Hope things are going well there...
Nice job man! I've never wanted a Tesla as much as I do now!
I imagine you've already been talking to Samy Kamkar about this project? (He is already a fan of yours.)

Microchip CAN BUS Analyzer is a nice tool for capturing data from the CAN bus. Also inexpensive.
really intelligent
Such a cool video! Did you ever do Part 2?
Man I should look into this I've been wanting to monitor the fuel flow in my car for a long time.
You could still connect the wires to a Bluetooth obd adapter and use torque to find the pid and log it through your phone. I would be interested to see if you could send an odb command though, the doors are controlled through one of the CAN buses.
The OBD2 port is required by law to be there and have certain information in it. I believe it is required to be within 12 inches of the steering column.
