I'm curious to see if anyone has experience working with CAN, specifically in an automotive environment. I'm starting on a project to snoop the CAN bus on my new car for some monitoring an information gathering. I'm reading everything I can find on Google, but if anyone has some specific references they would recommend, I'm all ears.
If you have a car post 1996 you can get a USB to OBDII converter and some software on your PC to read and display basic OBDII functions and check for DTCs. You won't be able to change anything though.
If you got a spare $15,000 lying around, buy a scan tool LOL.
I've worked with the HDS (Honda Diagnostic System) when I was working at a Honda dealership.
