[@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 :)

[@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?

[@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" ?

[@Adamyno]

Szia! Van egy USB-s CAN snifferem, sikerült elkapnom a kommunikációt. Egyelőre csak néhány alap adatot szeretnék értelmezni. Vannak hozzá tábláim, amikkel elvileg vissza lehet fejteni az adattartalmát az üzeneteknek, de nem mindig azt az eredményt kapom amit szeretnék. Nincs egy blogod vagy ilyesmi? Jó ideje érdekel a téma, végre mélyebben is bele tudok merülni egy kicsit. Igazából mikrokontroller programozásban megvagyok, csak a CAN asatokat kéne kibigizni és egy kis aprócska műszerfalat tudnék magamnak gyártani :)

Brother please, make for very easy explain about this video...i'm waiting for second part 🙏

[@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.

Thank you ! But at 13:24 you edited the MCP2515.h from 16 to 8MHz. There the pins are still showing 3 and 7. Is that not a problem? Should they not be configured differently for the UNO ?

[@mrs_radrod]

Thanks so much for this video. I would love to see the next part as that is really pertinent to using CAN to do data logging for my car when doing track days and making sure the vitals are all within operational parameters. Subbing for sure. Also thanks for showing basic Arduino setup. It’s very easy to skip over things that you’ve done before that seem simple, but that really does help me since this is a system I’ve never really looked at before.

[@almq1825]

[@bearwolffish]

There is so little on these topics outside of the iso's/datasheets, that in exploration of the protocols involved in the the communication with an R7 I am constantly rescued by the car community in my search for info. Wonder why is there such an abundance of people willing to throw money at proprietary options from random companies that are licensing from other random companies, and yet so little desire to understand how any of it works.

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.

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.

[@Adrian159396]

Hey! I have also started work on receiving and injecting data into the CAN network in my Opel Astra H GTC. I work on Atmega 328p and MCP2515 module. After several hours of trying and listening, I was able to set only a few IDs and data values. So far, I've been able to turn on several IPC lights and turn on the lights. In addition, the car went crazy several times, turned on the horn and a few other things permanently. I'm afraid to experiment blindly sending unconfirmed information, because I'm afraid that, for example, I will launch Airbag ... Would you share your notes, what ID and data do you send to turn the lights on and off, open the windows, etc.? I'm not going to the easy way, I just don't want to damage the car with experiments. In Poland, this is said to be "breaking open doors." That is why I am asking you for some information that you have already established.

[@adam_]

Thanks for your reaching out! You are right, you need to be careful with sending messages. Always make sure that your equipment is working properly and test that you are sending out what you really want. I don't think that my reverse-engineered message would work perfectly with that astra H. In the next video, I'll try to show my application that I used for reverse engineering. That might help you as well.

[@MrPery121]

Hey Adrian! Can you share with us which frames are you using to turn on the lights?

[@Adrian159396]

@@MrPery121 Hey! Uunfortunately I dont have ID and frames turning lights on. I can only turn on the IPC dashboard light controls. Once I was able to turn on the traffic lights, unfortunately the effect was that there were additional errors in the CAN bus, random lights came on and I couldn't turn off those lights. It just helped disconnect the battery. Adam Varga rightly wrote me to check my hardware and be sure that my harware is sending what I really want to send. He's right, because before, the frames read by "Super sniffer", when I sent them, various strange things happened. I will leave my car for a while, buy a second MCP2515 module and use one to send frames to the other MCP2515 module and check on the other which frames have arrived. In my MCP2515 I replaced the resonator from 8MHz to 16MHz because the mcp_can.h library contains the configuration for 16MHz. I recommend you such a "self test". The second module will be useful later to simultaneously support Slow CAN and Middle Speed CAN by a microcontroller.

I transcribed the frames I suspect to the second sketch injecting the frame into CAN every 2 seconds, uploaded the sketch and checked if it works. There were many attempts. The sketch lighting up the controls has long been overwritten with other lines of the Arduino code with (wrong) frame data when trying to turn on "traffic lights", so I don't have those frames: / Read this article: techtinker.co.za/forum/viewtopic.php?f=14&t=18 I use this as way to reverse engineering, but I think I'll try with other software. I warn you from my short experience! If you upload anything to an Arduino connected to CAN, disconnect the CAN cables from the car! When uploading a sketch to Arduino, some trash-data is transferred to the car via MCP2515 - the car goes crazy. As soon as I remember what the control frame on the IPC was, I promise to write to you. I have a key question: ID number and data from frames are sent in the form DEC or HEX?
