Small nitpick: “Every car has a CAN bus” except all the cars produced before CAN was implemented… lots of cars are still out there with some variant of Class 2 serial, and even cars that pre-date having multiple control modules and only have a PCM that runs just an engine, or an engine and transmission. In fact, ~85% of the vehicles I’ve owned thus far have not had CAN, but ~65% of them had some form of serial communication and multiple control modules. Second small nitpick: I don’t think the music is needed, I can deal with it, but it is a little distracting at times for me at least.

@@AndrewGerlitz no worries, that’s what growth and adaptation is all about. I personally was hoping for a bit more in-depth exploration of CAN hacking, but I think this is a good “primer” video for anyone just getting their feet wet or discovering CAN stuff. You seem to have no issues presenting clearly and in a manner that I’d think was pretty easy to follow and understand for just about anyone looking for content on this topic. I may have been a little too pedantic/nit-picky with your wording, I tend to be that way with accuracy sometimes. I feel like a majority of people ending up on this content are likely to be more familiar with what vehicles do and don’t have CAN, but I thought about it from the perspective of someone who ended up on this video with very little knowledge of cars and CAN who had a budding interest. Purely trying to provide constructive feedback, not nitpick just for the sake of it.

@@UnlikelyToRemember I agree with CANbus being developed and introduced in the 80s, by Bosch if I recall. But I disagree with it being in “all” US cars since the late 90s. I’ve owned, worked on, and modified a number of late 90s and early 2000s vehicles that only had single wire class 2 serial or some other variant of a single wire serial protocol to communicate between control modules as well as available at the DLC. I actually don’t recall seeing CANbus between any modules in GM vehicles until around 2004, and at least some those particular ones I can recall didn’t have the CANbus present at the DLC and still used Class 2 serial between all the modules as well. It may have indeed existed in some US vehicles since the late 90s, but certainly not “all” of them based on my experience.

Super cool, I'm thinking of peeking into CAN to see if i can get steering wheel angle sensor data for a backup cam project I'm working on. Depending on what's least invasive it might be easier than tapping the sensor directly. The downside might be that it would make installation more car model dependent if I want to share the project.

Andrew, this was awesome to see. I have a 2022 Sentra and I have a handful of things I would like to add to my home automation server from my car, and I was thinking CAN injection would be the way to go. As an experienced electrical engineer but total noob on CAN messaging, where would you start? I want to add things like lights, remote start and a bunch of feedback sensors from the car to a device that can communicate through a cellular modem to my server at home. Its feels very overwhelming to even think about where to begin. I am trying to find someone experienced that could help me get started with some advice. Im even willing to oay, because this is some niche knowledge.

I know the feeling, I was told it was too much when I picked the project. Like any project, lay out everything you want to accomplish, and start working at it one thing at a time. In your case, I'd focus only on getting a reader, and figure out how to sniff data. Once you get a feel for that, then look at actually forging some packets (Start simple, like a traction control light! See if you can find the DBC file for your car on the internet, it'll save a ton of time). Then you should have a better idea if what you want is feasible via CAN, or if you need to make any adjustments. Worry about the transmission of the data and the server side stuff later (Something like a rasPi or arduino with a GSM module can take care of that). Feel free to DM me on X if you have questions.

I would like to have a device that could be plugged inline between the scan tool and the OBD-II port such the device would tell the scan tool the MIL is off and that there are no malfunction codes stored. It would have to pass the VIN and other vehicle specific info. Does anyone have an idea how to do that easily for someone who handy with building hardware but not so much writing code? Does such a device already exist?

Challenge: Find the telemetry code that sends data back to the manufacturer for data collection and third party sales and disable or destroy it. That would be a huge public service!

The steering pump is a hydraulic system independent of the CAN system (Aside from maybe a steering angle sensor). The only potentially exploitable thing would be some sort of assisted driving mechanism, things like lane keep assists, or self driving of some kind. Even then, depending on the implementation it may require other methods to exploit.

This is very elementary. using the can system to tell features like lights or windows is one of the first and easiest things done when diagnosing a repair. you can pretty easily get a scan tool with the ability to use the canbus for a few hundred dollars and they work on any car with an obd2 port. is it anywhere near what you were talking about in the beginning when making a comparison to the f&f movie? not even close. no vehicles yet have the ability to be messed with any exterior programs that aren't plugged into the obd2 port. you could say stuff like onstar and remote self driving control are getting close but they are a lot more limited then what they appear to be
