How to hack your car | Part 2 - CAN Sniffer app

[@MacNate_]

5:08-5:13 noise distortion, anyone? No one noticed? even cc communication was messed up. Aside the complaints you made a great video !

[@Factory400]

This is amazing timing.....I have been studying QT GUI's, designing new products with CAN bus, and have a personal automotive project that needs detailed CAN logging and analysis. Fantastic.

[@Mircea007]

python, arduino, CAN Bus, all in one video. amazing stuff, thank you for taking the time to show this

[@iphooi]

Started a few projects recently for my car, and as a non-car person, I just started to learn about the CAN bus and its use in vehicles. I have to say, it amazes me in its simplicity and reliability. Currently putting together a sniffer with ESP32 while I just found your content. These videos are made unusually well; they cover everything that one needs to understand to start their hacking fun. Wish I started here, hah. Köszi Ádám!

[@Aircooledboxers]

Thanks for the video. I love the organized and methodical method you use to teach build the process in the videos. CAN Bus is sort of a side project for me that i just recently revived. I work on automated industrial equipment and have been looking to eventually cross over my knowledge from that field back to my original field of custom automotive/motorcycle. I sincerely look forward to all of your future videos! Thanks again.

[@POG7606]

Thankyou so much Adam! You are brilliant and freaking genius!! I have been struggling for a longtime with no success. Tried your software and on first go it decoded F-CAN. Thankyouu! My car (civic fd2) is equipped with Single Wire CAN (SWCAN) for B-CAN, as there is only one wire I don't know how to get data from that. I have that wire handy for sniffing purpose. Any suggestion would be very helpful brother

[@POG7606]

Omg! It worked connected chassis ground from obd port to low can of mcp2515 & set rate to 33.33 Once again thankyou so much.. I couldn’t have done with your video! Made my day!! Very happy!!! 😊😊

[@adam_]

@@POG7606 Glad to hear you are making progress, and thanks for the kind words! Your donation is much appreciated

[@AbhishekKr1902]

It is plain criminal to dislike such an awesome tutorial video, I have been waiting for such a project for so long man, and thank you very much Adam for making such a beautiful presentation on this. Love from India 🙂

[@fishburitto3914]

After difficulty with small MCP2515 unit, I decided to try Seeed Canbus Shield v3. To get Shield to work, I needed to switch CS pin to 9 in MCP2515.h. Also, 16e6 clock speed. Video 1 @ 13:46 has incomplete entries (missing 33ke) for MCP2515.cpp. Video 2 @ 17.:49 has the complete entries. Now it is working, thank you for the video, you are very smart. Will go further by seeing video #3 now.

[@fishburitto3914]

I also needed to do some soldering on the shield board pads to make the DB9 port work. Also needed to buy a DB9 jack and OBD male plug wire for DB9 jack. I found it useful to have a second shield in "send" mode so I could test the receive without having to sit in my car.

[@ThomasChapman-q9r]

Really nice video, starting from scratch I am now logging the CAN. Next is to try decoding some of the messages

[@stuffcc]

Really nice work ! You made my day ! There is an audio bug around 5:10 by the way. Keep up the good work, I really appreciate your videos as it is exactly what I need for my project as a beginner.

[@adam_]

yeah, dunno why that happened. I've checked it several times before uploading.

[@jayarchitect]

The highly anticipated part 2....leggo!!!

[@HUDSON-EV]

Thank you, I will try to use this to log CAN Bus data while I do a test drive. Keep up the great work.

[@sfcoawol6273]

Been waiting for this for a while! Thanks so much!

[@iikurt]

If you're using an ESP32 instead of an Arduino like I am, the ESP32 watchdog will kill the 'onCANReceive' function when it prints to serial (as this is quite a length process). I solved it by making a global flag when there is data to be received, and then processed it and printed to serial while in the loop, where the watchdog isn't watching.

[@pm9601]

Yay! So happy part 2 is finally here - Thanks Adam - fantastic video!!!

[@lakshminarasimmanv]

At last its here. The wait is over.

[@chandvirdi27]

amazing work Adam

[@kyleagronick9627]

Cool app. The interface looks great. I'm curious why you didn't use the pycan library. I ordered a USB ELM327 interface. It seems easier than wiring an Arduino.

[@jackspratt4343]

Does the main engine ECU ( black box ) always have to be connected for the CAN BUS to work ? What I mean is, do sub systems broadcast and receive messages among themselves or does everything get parsed through the main ECU. From your experience. Thanks you.

[@adam_]

Good question! I believe there are some information that are being 'queried' by the ECU itself, but in general, subsystems do not need a 'master' to work. So, if you remove the window controller module from your door (if it is a CAN based digital module), it will emit signals upon button presses.

[@TheArdanwen]

Thats cool.... Can you sniff the Codes for the automatic trans.. ? And reprogramm them on another switch ? Like paddels on the steeringwheel ?

[@adam_]

Sniffing might work if those packets are available on the High speed bus, but you won't be able to reprogram them for sure.

[@Dean_Leslie]

Loving everything so far. Bit of help on one thing. I have come to the point where I go to 'pyqt5_tools' in there I should find Qt/bin. I do not. I can find this in 'pyqt5/qt/bin. The only designer I can find in there is Qt5Designer.dll, which is a system file. Any ideas? Thanks

[@adam_]

someone had this problem before I think. Are you using a MAC? I'd suggest searching answers on QT forums, or google. I haven't experienced this issue yet.

[@Dean_Leslie]

After a bit of digging, it appears that this must be something the programmers have sorted and it is already available to use within the files. Simply typing designer.exe in the windows search bar, it pops up and is ready to use ;)

[@v12cat]

Brilliant series of videos! Your app works really well! Just a quick question. I have a message that is very 'busy'. It contains the output from at least 70 buttons and dials, amongst many other things. How would you go about narrowing it down further? It kind of needs a sub filter for some of the bytes. Eg. to show just message 0x613, Byte 0 (value 0x15) for instance. All of my buttons are on message 0x613, with byte zero set to 0x15. Other 0x613 messages are sent reasonably frequently.

[@mehdizeynalov1062]

super video - just one question - i could read the canbus, but the messages were shown encrypted, do you have an idea why could that be? also I tried to change the frequency to 1MHZ, which screwed up a lot of things, so it's not recommended to do.

[@adam_]

What do you mean by encrypted? IF you are getting a lot of nonsense data, it's most likely a mismatched baud rate issue.

[@the_rafa0398]

Very good information thanks for making this video and sharing your knowledge

[@458med]

Thank you for your help, I have a question, my data does not look like yours. Almost all my ID are 8 bytes, such as "1020C040" except one which is "624", all RTR are "00", all IDE are "01" except the "624" ID. The radio up data looks exactly the same as the radio down data: ID: "10AD6080", RTR: "00", IDE: "01", DLC: "08" followed by D0-D7: "02 06 17 02 00 00 00 01". When I playback message, the radio does not change. Please help me understand what I did wrong, thank you sir.

[@458med]

Also I should say I am using an electric car 2018 Chevy Volt on 33.3k bus (GMLAN) pin 1.

[@adam_]

All cars are different. There's nothing wrong with your data, you just have to understand it, and I cannot really help you with that since I don't have experience with that model. Try to experiment more and search on forums.

[@sodapunpunnarai2336]

Can this support canbus with include gateway protection? I have microchip board but I can scan old machine before 2014 but the new car has gateway I cannot get any data from them. Can you advice?

[@burakaydnalp5804]

Thanks for video. I've been waiting for this and now I'm waiting for next video :) . I'm working on Fiat Linea 1-4TJET. My car's canbus is very different from yours. If there is someone working on Fiat Linea, they can connect me.

[@toms8818]

Well done! Thank you Adam.

[@BinaryAdventure]

Nice video and thorough explanation. Thanks!

[@HUDSON-EV]

I'm having issues with this. I have followed your every instruction, however the GUI is not working. This instruction worked up until the clear and reset function. Because it refused to work, I decided to move forward and try to open the GUI app. Arduino file had no problem opening up but the GUI did not want to run at all, it just says "Process finished with exit code 0". Any suggestions? Addendum: I figured it out. I wasn’t using the correct file and I was missing some libraries. Thanks for responding.

[@adam_]

The GUI issue seems like a python related thing. Try to isolate the program, comment out parts, etc. It worked for several other people, so I cannot really sugesst anything super clever here.

[@antaljani]

@@adam_ Sajnos Ez nem platform független megoldás, mert a módszer, amit a videóban mutatsz, csak Windows alatt működik. Sem Linux, sem MacOS alatt nem megy az említett dependencia problémák miatt, amit sajnos - lévén nincs ebben semmilyen gyakorlatom - nem tudok feloldani. :( (hozzáteszem, hogy természetesen rágugliztam, sőt, a pip tool is ajánl egy oldalt, ami segíthet, de az említett megoldások egyikével sem sikerült életre lehelni a QT tools-t.) De ha valakinek van jó ötlete, hogyan lehet feloldani ezeket a dependenciákat, akkor szívesen veszem.

[@antaljani]

Siker! Volt egy kis szívás, de sikerült működésre bírni, a titok nyitja, hogy a Qt5 install nem megy PyCharm-on keresztül, hanem le kell tölteni az open source verziót és a MacOS verziót fel kell telepíteni. Qt Designer helyett Qt Creator van, ami tartalmazza a Qt Designer-t is. Továbbra is kell a virtualenv, ahogy a videón látszik. Futtatáskor jön is a hibaüzenet, hogy nincs pyqt5-tools, de egyszerűen figyelmen kívül kell hagyni és elindul az alkalmazás. Hogy aztán a sniffer-rel működik-e majd rendesen az kiderül a héten, amikor megérkeznek az alkatrészek. Remélem igen, ha nem, akkor tovább kell kutakodni...

Hi, Great videos by the way. Can the MCP2515 store and push out CAN messages without the presents of the laptop. Does it have the capacity to be programmed this way? Thanks

[@adam_]

No, the MCP2515 has no logic in it. It is just converting a CAN packet from a microcontroller to singals that can travel on the can bus. But obviously, you can do whatever you want with a microcontroller and program it to do things automatically for you.

Great videos and software. I am having some trouble reading my can bus though. I can get everything working with the random packet generator but can not read from my bus. I have changed clock frequency back to 16e6 for my shield. Changed random_can to 0. And made sure cnf_mapper is the same as a library that I know works for me. Also set can_speed to 125E3 which also works for me in another library. I just get "Starting CAN failed" message on serial monitor. Any help in the right direction would be great. I really like your software and think it will be perfect for what I want to do. Thank you for the hard work you do and sharing it with us.

[@adam_]

hey Josh. Usually, the library is giving those errors if there's a bad electrical connection, and thus, the voltage levels on the lines are incorrect.

[@s89281b]

Thank you for the tip. I will double check my wiring and also make sure I don't have data lines crossed. Will post back what I find when I get it working incase anyone else is having similar issue.

[@TxRGaming2570]

hello Adam great video , all good so far i can sniff with random can , when i go random can = 0 i only got rx tx started , i think is something with the can calculator or cnf_mapper , you on video on the calculator you put 33,33 on can bus , my question is how you got that number ? i try with 500 bit rate and nothing

[@adam_]

First, you have to make sure that you know what speeds your car is operating at. Then you need to match the oscillator frequency of the mcp2151. Then, I recommend you to try the arduino examples, as I explained in the video. The random can doesn't do anything else, just creates random can packets.

I feel you, I've experienced the same. Different calculators will give you different values mainly because of the different sampling ratio. The best is 87.5% or something like that, but you should be able to receive and transmit with different ratios too. Just try out a bunch of values and see for yourself which one works the best.

Hello. Thanks alot for your work! I'm trying to hack my peugeot 307cc. I've got another shield that is the MCP1525 V2 from seedstudio, for Arduino uno in 16Mhz. Will your .ino file work? With what modifications? How does it push info to your python code (serial?). Finally, do you plane to make an executable of your sniffing .py? Would be really great!

[@adam_]

Hey. Unfortunately, I don't know if the library will work with the 1525 or not, but I think there are some differences between the two. You should find a compatible arduino library for that module. You can create an executable yourself too. Search for pyinstaller
