How to hack your car | Part 1 - The basics of the CAN bus

Great video by the way thanks for uploading. Btw, anyone who's manged to get IDE to print "CAN Receiver", but has not got any CAN data...... I had this problem, did a day or so of debugging, turned out to be a defective MCP2515. Worked perfectly after swapping for another. Try swapping them if it doesn't work!

I'm an industrial control engineer just breaking into CAN bus communication to sensors brought to the industry in the past 10 yrs. We work mostly with PLC's on either hardwire, RS-485 or EthernetIP....now there are sensors on CAN...the older PLC's need change outs and we need CAN adapters and understanding to re-engineer these PLC systems which become outdated. Thanks for the intro tutorial of the basics.

Really nice video I am building Omega with BMW engine(car is running for 3 years allready), and I have trouble with omega esp to ecm and various additional systems like cruise etc. I am mechanical engineer, but i desperately need someone with deep knowledgemenet in electronics. I have tried self learning but 0 times something still equals 0. Evey this kind of video boost everytime.

[@thelondonbroiler]

This is a really great tutorial, I know it took a lot of time and effort, thank you! Hopefully with the knowledge you're providing, I can figure out how to activate the battery heater in my electric car, so when I take road trips in cold weather, faster charging speeds can be achieved. Tesla does this, but my GM EV does not. Thanks again!

[@adam_]

My first tip would be to get a somewhat official diagnostic tool that they're using in the repair shops. With that tool, you should be able to trigger the battery heater ON and OFF. All there's left is to catch those messages with your own sniffer, so you can manually send those commands later.

[@thghho]

​@@adam_​ I am getting required message, now how to decode that message? and in which format to send it back?

[@ekasusilo]

I don't seem to see a lot of CAN frames on my hybrid Prius 2017. I have the exact same setup like in this video. I am expecting to see more than just a couple of CAN IDs. I also tried to put a jumper on the 120 ohm terminator, but it does not make any difference.

[@nikolapremcevski9051]

I've been waiting for this for almost half a year since you first uploaded the video with your vectra! Awesome and very informative video. Would you be kind enough however to provide the links to the exact hardware that you ordered/purchased ? I have the same car (also 2005) and I attempted a similar thing last year with an arduino uno and a CANBus shield - but that one is made for exactly one canbus speed and not much data can be accessed with it therefore. Looking forward to part 2 :)

[@thghho]

[@EmreKonca]

Hi Adam, I made connections like your "wiring diagram" on my Opel Crossland X 2020i I measured 12V with multimeter on "Low Speed Can" line. Is that normal? Other question, may i change the can speed when sniffing medium spped or low speed can?

[@adam_]

12V is probably not right. You can change the speed, but you need to change the connections anyway, so I don't understand the question.

[@EmreKonca]

@@adam_ thanks for fast reply. When I sniff the low speed can line, may i change the can speed variable on the arduino code to 33e3? You connected the low speed can line to pin 1 and pin 4 on the obd2 port. Pin 4 is gnd. So how can canbus data will flow?

[@adam_]

When you sniff the low speed can, you HAVE TO change the speed to 33k3. In the vectra (I don't if this is true for all opel cars, but probably) the low speed bus is called GMLan. This is a single wire protocol instead of the usual Can H/Can L. Actually, you should think about it GND being the Can L for this bus.

[@EmreKonca]

@@adam_ if 12v between pin 1 and pin 4(gnd) is not normal, how can i find the right pin? How can i be sure about which line has "ligths, window controls etc" ?

I have triple checked all the wires, they are connected securely and correctly. I have the exact same MCP2515 board he is using and the UNO R3 as well. Apparently it may be because I do not have a 120ohm resistor, but the video didn't specify that. Wondering if thats the case. Any suggestions to fix this issue?

Hello Adam . I have a Vectra C 2004. The stock player was Siemens NCDC 2013 and the BC button is on that player and i don't have it anymore . The steering wheel have 6 buttons. I can't use the board trip computer and the other functions . It's any chance with the arduino to set the 6 steering wheel buttons to navigate on the display to see the trip consumption and other info ? Thank you for your time , you do a greate job and make a lot of people happy with your knowledge

[@adam_]

I think it's possible, but I'm not familiar with the NCDC2013 :/ First, you need to learn the messages of the steering wheel and then figure out how to control the player.

[@JoseLopez-mj5gw]

Hello Adam. forgive my english but i'm using google translator. Spectacular videos. I've followed in your footsteps and I can sniff the net on the high and low channel, but not the middle. My car is a 2017 opel astra. But the main problem is that I can't send command to the can bus network and I don't understand why. The 500 and 33 speeds work fine. 95 does not work `at least on pins 3 and 11. Why can't I send data via can bus?

[@Scortexx]

Great tutorial! The only guy where I found that the baud rate has to be higher! I didn't have success in connecting my shield to my car, I will try it again, I hope that it will work using these methods. I only want to read multimedia data because I want to make a interface for my Renault steering wheel command for my radio. Also I want to make hand gestures using gesture sensor just like in BMW 7 series :)

[@Scortexx]

Just to let everybody know and to thank Adam Varga, it works, it lists CAN BUS codes, now it is just a thing to find the ones I need, for the radio control.

[@SimonPlatten]

I have lots of boards, shields and cables, so far apart from spending a lot of time trying I haven't managed to capture any data from my car (Audi A5 2012 2.0 TDI), I've tried using a cable to connect to the CAN BUS via the connector on the dash, I've also tried a device called a CAN Crocodile which allows you co connect the device over the cables without cutting. Still haven't managed to capture anything, this could be due to the speed which I have no idea on.

[@Ro_Wa]

That was a very well made video! Thank you for your time and effort explaining everything very clearly. Have you tried replacing the 8MHz oscillator with a 16 MHz oscillator and could you imagine possible advantages? The library I tried to use, was configured to 16 MHz and didn't work at all with 8 MHz. After swapping the oscillator for a 16 MHz, the arduino could communicate with the MCP. I however, didn't manage to get any data of the car. I will try out the library you used. I am looking forward for the next video. Have a nice day!

[@adam_]

Thanks for your reply! Yes, I tried with a 16MHz oscillator, but for the sake of the tutorial, I thought that it is easier to just modify a define rather than re-solder the oscillator. Actually, there's no real benefit unless you want to achieve a really weird frequency that the mcp2515 is only capable of making either only from 8MHz or 16MHz.

[@michaeldruyan1506]

About the junction box, what was the reason you used 2 independent switches and not one DP3T switch?

@Adam Varga Hi, I followed the tutorial and I got it to display "can receiver" but I'm not getting any data, would you have a idea what could be wrong?

[@danradum]

Some cars have the OBD connector behind a gateway that is filtering out the traffic from the internal CAN network unless you request it to route it. This is one potential cause.

[@kapazo13]

Thanks for the video and sharing your findings, i was looking something similar for a long time. I have made the setup you show us. I can use the examples, like read the rpm and read the vin code etc. Although the examples doesn't always work. For example the rpm doesn't always show in the console. My connections am pretty sure they are good. Do you have any suggestion? Also when i try to read different PID i cant make it work either. I try simple PID to keep the code same as the RPM example and if it works to move forward to something more complicated. I try to read MAF sensor PID since it is very similar to RPM PID. So i changed the code from the RPM example CAN.read() != 0x0c // correct PID RPM PID to this CAN.read() != 0x10 since 0c is the rpm hex and 10 is the maf value and also change the calculation algorithm to match . But it doesn't work i get no data at all.
