Vehicle Can Bus Access

not really sure where to put this, so please direct me elsewhere is this is not a good fit for this question.

I am currently exploring car programming via the OBD2 port. I have been scouring the internet for a OBD2 solution that will allow me to read RAW CAN bus messaged from my car. So far I have not been able to find a software that lets me do this with a ELM327 adapter. Does anyone know if there is software available that can read these A.) with this adapter and B.) Actually show me RAW CAN messages?

So far I have only been able to see the OBD2 messages, but I would like to get under this layer. Any guidance here is greatly appreciated!

Thanks!

If your car is recent enough, you won't be able to get the "RAW CAN" traffic. Because behind the OBD port is a gateway that only relay SOME of the CAN messages.

You can still get those messages with your ELM but as this device is not made to be a CAN adaptator it can be tricky. You can find a lot of information here.

To get more information on what you can find on the CAN bus of the OBD port, you can read this article. It's a good way of having a first overview of the CAN bus in cars.

If you want to have access to the CAN traffic, you will have to do some soldering on your car's wires. Here is an article of what it can look like. WARNING : do not perform random stuff on your car, it can be as dangerous as expensive.
