Quite thorough, more than I expected, you are a good detective, engineer and hacker.

That's really nice, More contents on CAN bus please.

Yea it is quit difficult without the CAN-Matrix to decode the Messeges with the Signals in it. VW keep this closing like hell. Your way with try and error is really nice. Keep going

Thanks! SavvyCAN also added support for this protocol 5 days ago

Awesome stuff, thanks for posting

Great video Aaron.

Great, in depth video. Danke.

Excellent explanation! This is what I want to do. Thank you

Thank you for this video, hello from Venezuela

Great video 👍

Nice job!

Great video Aaron and thanks for sharing. I have done something similar but I'm very much a novice so your video has given ma lots of new things to try. I've subscribed and looking forward to more videos about CAN-BUS hacking. Good luck and thanks again

Great video, thanks

The bluepill stm32f103 already has CANBUS controller included.So you don't have to use mcp2515.You can connect TJA1042 to bluepill with only two wires. And also, there is a working lib for it

You should see some 2018 and newer stuff with 3 CAN networks, multiple LIN bus, multiple gateway, secure gateway, ethernet and wireless networks. Good times !!

I bought an older electric car last summer. But being older it doesn't have the fancy features to allow you to connect the car to a cell phone. So, I'm going to try and build an ESP32 device that will read the canbus and send me data. First thing I want to monitor is charge level so that I can tell when the charging cycle has finished, I'm fortunate to have 2 charging stations at my place of work.

wow!! This is great work!! I have a few questions. 1) do I need to pick a baudrate before I connect it to the car canbus or the sketch or canhacker will auto detect? 2) I'm using sparkfun canbus and it takes power from OBD2. would it be a problem to connect the USB into PC together?

Hi Aaron, thanks for your vid, I'm just starting to learn CAN Bus my goal is to sniff/decode/display some missing info on my EV car by using Arduino Uno + shield + screen thanks again.

Those Android head units can also read can data for things like outside temperature, reverse gear indication. I wonder if they can also write data too. Great video!

Hello dear It was an honor to watch your training video. I have a question How to activate relay module by using mcp 2515 and arduino nano board at specified engine speed, for exam 4000 rpm? plz guid me by make a short clip. thnx alot...

Sure looks like a lot of work. I just installed a 2 amp trickle charger on my cruze,cause something it doesn't get driven for over a week. But I am fortunate enough to have a garage

For anyone getting the forbidden error go to the url after you get the error and delete ".zip" then hit enter.

Great video! I've checked out your fork of the MCP repo but I'm unclear how to get exactly what you have going in the video. Could you link me to the arduino INO file to make this work?

Very cool

Great video !! I am not sure if anyone else has faced similar issues. I did all required changes for 8MHZ but I am not able to receive any data on reading. I tried sandeep mistry code, there I am able to receive RPM ( example code) but same no output in CANreceiver. Is there anyway I can figure out the issue ? Thanks in advance.

Hello Aaron, first of all - you are making a great videos witch so much knowledge there and thanks for that - keep up the good work! Now to my issue - is it possible to get it touch with you? I am dealing with a problem of 2 different CAN-BUS versions that i need to translate messages between them. Can we discuss this please?

I reversed engineered a VW and ended up with a WV ...everything is backwards.. Mmmm? thanks great video...:)

Hi you gave me a few ideas. I have a radio like that it has CAN built in the radio. there is an app to set the address and bits. I want to monitor my 2019 Jeep JL. I like the sleep function.

Thanks for this interesting setup. Do you need special software initialising for the arduino nano/uno? I think you need some firmware to start with? Is nano better for this or uno? I never used/played with arduino. This would be great for CAN sniffing of ebike communidations (BMS with Drive Unit e.g.).

Great information.. I just ordered some MCP2515. I have a problem with my Jeep Compass where remote door locks stopped working. I have a aftermarket remote starter that works by pressing LOCK on the remote 3 times, and signal is sent over CANBUS. Hoping this may show me if signal is on the BUS. Do you know if your car shows LOCK/UNLOCK?

Could have been fun to see you send a command and have the passenger side airbag go off. ;-)

Hello my friend. I have a nano arduino and a CAN bus MCP2515 interface. I made the connection like yours to the nano and I can connect fine to IDE and Canhacker, I can also upload the sketch without any issues the problem is in the canhacker I can not see any data. Tried connect on desk, directly to the comfort can bus on the cluster and also to the ODB connector. Any advice? I only made a modification to the canhacker.h from 16mhz to 8mhz in the CAN CLOCK portion. Any advice where to look?

Really nice video. Thanks for share. Let me ask you something. What I need to read lights signals from a car and send those data signals to a arduino board with a Led library to make smart Leds act with parking lights, turn signals, brake, drl, dome lights. It could be possible? Thanks in advance

interesting video although i dont really understand hexadecimal and things like that. I was looking for information on canbus and your video came up first thats why i decided to watch it. my application is different and maybe you can point me in the right direction on where to start. basically i bought a electric turbocharger it was originally installed on an Audi Q7 4.0 tdi quattro. i do not have access to the vehicle i only have the turbocharger. i learnt it is 48 volts i know that much i also learnt the 4 pin connector has 2 canbus wires. now i need to figure out a way to send messages to the turbo so it can spin. just so i can do tests for now. so do you have anywhere for a beginner to start on this? i really dont know where to start with this. all im wanting to do right now is make it spin if i can figure out that part the rest will get easier hopefully you can help me out on where to start. Thank you in advance

i can not add MCP2515 library, can you help me, it says "missing header file arduino-mcp2515-master.h"

Hey, i have a Dynaudio amp from VW which has a wake-up lock on it. Also, have an Arduino CAN module. Could you please help and send the sketch so I can unlock the "wake up" with it?

I think you will like commaai opendbc and cabana

Hello Thanks and for your video. It's nice and you good in English. However I tried to buy from pcbway. I am at a lost. There are too many options and I don't know what to choose. I want the one that works for you. Also is there a possibility to get the PCB with the chips and smd parts. Thank you again

Hi great video! How can you determine what each CAN ID represents? For example, how did you know that 353 is the RPM data? thanks

Excellent video! How do you know that the message bytes under 571 corresponds to the battery level? did you get that from a sort of datasheet or from where? and how did you find which one corresponds to the RPM of the car? (Du kannst auf Deutsch antworten falls du möchstest, ich kann es auch verstehen).

Is possible after we fund the rpm signal activate something when let's say, when hit 2000 rpm activate an 12v pump?

hi, it is normal to have on can bus 12V?

How did you get past the gateway handshake? Or are you talking to the CAN BUS after the gateway?

Hi, can I just use TJA1050 module, and connect the TX and RX to the CANBUS port of android car head unit?

Cool video! Don't you need the same gnd between car and laptop?

Hi Aaron! Great video! Have you got a link for downloading canhacker please?

Hi Aaron. I have a question for your project. I 've completed soldering arduino nano with mcp2515, and could you let me know if I put my can high line and low line to the obd2 socket directl?? would it gonna be working? Also, can I clear DTC code with CANHACKER software if I connect to car obd2 ???

greetings, excellent video. how can i do i need that when i exceed 20 km / h read that data and turn on a light bulb. Thank you.

Hey Aaron, hope you're doing well. A good and interesting one. I believe I can use this to get real-time data from my motorcycle. What's the difference between OBD2 and this CAN bus?

Does it work with 29 bit CAN ID? If I have 3 rd party ECU 29 bit CAN IDs, how can we receive data from that?

Hi Aaron! Thanks for your video. It happens that the link you informed for downloading the CAN Hacker software is not working, do you have another mirror? Thanks!

how to sniff for k-line do you know module for an arduino?

Hello, I also have a problem, I can't capture a single time through the can from an Audi tt, I use mcp2515 8mHz, if you can help me a little, thanks!

Long shot but on transportert t5.1/t6 / caddy/ Tiguan. Use the same 3 bottom heater module( but controlled via canbus / could u make one to power it up

I'm trying to figure out steering wheel controls on 2017-2021 kia sedona.

Hi can you share the schematic of your board and the BOM list?

How can i give Internal mcp2515 registers instruments by spi comand list?

Hi Aaron, do you know how to sniff GPIB command from al the instrument connected in the GPIB network using adruino?

Hi Aaron, great video, where did you find the information about the "ID 571" to be the battery level?

Dude , from what part of Germany are you?, I am opening a workshop in HH. the line 3E1 is for power steering wheel 😉, Xanalizer is a fun tool to test

Hi Aaron. I follow your instructions but I can only see my own message. I cant see can message. Obvious the can is working fine because I can interact with other tool. Any idea?

When I try to read with Canhacker, it appear CAN interface not responding. What it can be? I configured the can and com baud rate and

I can't seem to find a similar board with ata6625 for LIN sniffing :C

So you used a different transceiver chip? And how did you set standby mode on the mcp2515; using a gpio on the arduino?

hello! can I send to can too? or just preview? I want to discover the rpm signal of vehicles, to test electrical directions on the bench, some need to be rotated via can.

Hi which PCB design software are you using? thank you

which radio did you swap the stock radio for? any links?

Hi Aaron, richtig gutes Video. Aber eine Frage. Was für ein Baujahr ist dein Polo 9N3? Ich habe gelesen dass die 9N3 Serie noch gar kein CAN BUS verbaut hat. (Zumindest nicht am OBD2 port)

Hi Arron, can you confirm which firmware goes in the Arduino to run with CanHacker? I assume CanHacker needs a specific data format from the Arduino serial output? Does CanHacker work with the CAN_read.ino expample in the ardunio-mpc2515-master library.

Hallo, wie geht's dir? Ich habe einen Polo 9N (aus Brasilien), fast der gleiche wie deiner, aber er hat das Display auf dem Panel. Ich würde gerne wissen, ob es eine Möglichkeit gibt, es mit meinem Android-Multimedia zu verbinden, da das alte Radio RD keine CAN + UND CAN-Anschlüsse hatte. Es verfügt über RCH-, CTRL-, LCH-, +8-, SWC-, CLK-, DATA- und ENA-Anschlüsse

Hi Aaron, fantastic video, just what I'm looking for to diagnose a problem with my MK7 Golf Front ACC Radar. Do you have an up to date link to the Canhacker software as the link in the description no longer works. Thanks!

Great Video, couldn't download the software, got an message saying you dont gave the permission, Are there any other links?

Can i read data in a Elevator system's MODbus or Canbus so that i can find out the floor number shown in the display using arduino? Please help

i am not sure why you are bothered with the power draw of the MCP2515. since that is powered by the arduino, if the arduino is powered from the ignition switch then if you turn the key off all the power source are shut off (no power draw)

Hi, I need the canbus code/parameter to turn on a VW factory radio with the car, can anyone help please? So that I can use the can bus shield with Arduino to turn the radio on on a repair bench.

Hi, tolles video zur richtigen Zeit. 😊 Der link zur can-Hacker software is down. Kannst du den nochmal senden bzw. eintragen? Mfg aus den Alpen

Hello sir Thanks. Please share me software name & website Thanks

Hi Aaron, this is a great video. I found it very interesting and thought of listening my Suzuki car . So far I am able to recognise some IDs connecting to obd2. I am able to send the can message to car but with a limited effect. I can send turn indicator messages and it only flashs turn indicator on dashboard but not the actual indicator. Same with the headlight message it glow the dashboard but headlight is not turned on. Can you please guide me.

Hi. May I ask how you managed to connect that ArduinoShield to canbus system physically. I'm not very into to electronics and kinda scary to me, I'll be very glad if you discribe and share a picture or something. Also have VW Polo. My main issue is getting two canbus lines from one output at multimedia dashboard(For testing I wanna both headunit and arduino connected to canbus network, from one cable located at dashboard multimedia system.).

Could you give us a video on how you do the code please as I'm struggling a bit 😬

Does it not need a common ground, or is it because both USBs are connected to the same power supply (computer)?

Hi Aaron... it is not clearly mention, but did you replaced TJA1050 with TJA1042 or just added this extra wire to TJA1050 ?

I need that software, please

Hello how are you? I have a Polo 9N (From Brazil) almost the same as yours, but it has the display on the panel. I would like to know if there is a way to connect it to my android multimedia, since the old radio RD did not have CAN + AND CAN- ports. It has RCH, CTRL, LCH, +8, SWC, CLK, DATA, ENA connectors

Hey Aaron. Can you increase the car's RPM by sending a CAN BUS message? nice video by the way.

Hi, I really like what you have done here. I am trying to use the software CanHacker you have mentioned but I cannot get any data to appear on it. I can initialize a connection successfully. By using some of the example libraries for the MCP2515 I can get can bus data to appear in a serial monitor but it is very hard to analyse this due to the speed at which the data appears on screen, hence trying to setup the CanHacker software you are using. My setup is the same as yours, I am using an Arduino nano and the same MCP2515 board. I am wondering if i have the can adapter code configured incorrectly. Very much enjoying your videos if you have any suggestions I would appreciate it very much! Shane.

Hi Aaron, great video. I want to download software but link is not working. Give me link for download , please!

what changes in the code you did to configure the bluepill to connect with the MCP2515? what are the SPI bins in the bluepill that you used and how you selected them in the code?

Bom dia, gostaria de saber se consegue ler RPM e temperatura de todos os veiculos, preciso de um projeto para essa finalidade, desenvolver um produto, se interessar a parceria me avise.

Hi, great video and great job! The link for the software is down. Can fix, please? Thank you.

in place of can h&l pin , can I use OBD II port to sniff ?

Hey Aaron, My UNO gets connected but it does not show any data on the software. Please tell me what can be the problem

are you german? because your accent sound so familiar. nice video

nice vid, and i getting date, but it does not refresh/count, i did the same install like you. any options or idea what happened?

Hey Aaron! Sehr informatives Video. Danke dafür!. Ich habe ein kleines Problem mit meinem android Radio in meinem t5. Ich krieg kein zündungsplus über den Adapter raus. Heißt Radio läuft wenn ich 12v auf acc gebe. Komischerweise kommt übers canbus wohl kein Signal. Lenkradfernbedienung usw geht aber. Mein Auto hat tp1.6. Beim Kumpel mit tp2.0 kriegt er mit meinem Radio zündungsplus raus über canbus. Kann ich das irgendwie richten? Der canbus Adapter ist von rais und besitzt auch Pins zum programmieren wie ich das gesehen hab. Dankee 👍🏻

Any way to get this to work with a SparkFun DEV-13262 CAN bus shield? (which uses the MCP2515) I tried it but only got a handful of IDs that stopped after one count each...

Hi friend thanks for sharing your knowlodge, your videos are very complete regarding a can bus project, Im just starting on this but I have a problem, I cant find the software that you mentioned and micrtornics pages shows a message"403 Forbidden", could you give me a hand? regards from Mexico.

interesting, but the can-hacker links seems to have died. (and consider a gorillapod or something to hold the camera, shaky video really brought the otherwise good video down a bit)

Können Sie Deutsch sprechen? Just joking but can you send me a few bottles on Augustiner Edelstoff which is unavailable in Canada. By the way, excellent info. I am just learning about CAN BUS for the fun of it.

Does anyone have a new link to he can hacker software? Also, does anyone know how to use the new R4 Minima with his project- I have an M4 can module which ill use in conjunction with it...
