> "Tesla is the same pattern applied to consumer vehicles" It really isn't. Unlike John Deere, Tesla is actually pretty good on right-to-repair. All of their technical and repair manuals are available for free to anyone. The service/diagnostics software ("Toolbox") is also available to anyone, albeit for a (not entirely unreasonable) fee. (There is also a service mode built in to the car which can do many basic diagn…

Being forced to release manuals doesn't make them good (thanks Massachusetts).

This is a misconception. The Massachusetts right-to-repair law didn't force Tesla to make their manuals free.

As others have pointed out here, other manufacturers like Ford and Toyota still charge for access to their manuals, even in Massachusetts. Tesla gives free access to anyone, worldwide.

Not sure - if I was designing it, feels like it would be a good way of getting the right build to the right car so that all the HW versions of each module are in line.

I'd imagine that the update includes all the possible hardware, and the update script actually decides which components to use. Like apt on Debian or yum on RHEL.

Interesting - just found this: https://www.pentestpartners.com/security-blog/reverse-engine...

Not had a chance to read it properly but definitely will be!

That was an amazing read, thank you!

It appears that the Tesla is running a full Ubuntu Linux distro. And here's a small quip to entice passers-by to read more:

From the article > Tesla offers a “Root access program” on their bug bounty program. Researchers who find at least one valid “rooting” vulnerability will receive a permanent SSH certificate for their own car, allowing them to log in as root and continue their research further. Pretty interesting. Sounds like Apple's Security Research Device Program[0], where you're loaned a rooted iPhone, but with a clear qualificati…

It's a mixed bag. This only applies to the infotainment system and not the autopilot computer. They've also revoked certificates from researchers personal cars in the past

FWIW, I think they share resources. I was able to crash the browser via a GPU benchmarking website while using autopilot. Autopilot disengaged and the “instrument cluster” lit up like a Christmas tree for a few seconds.

So I’d imagine an infotainment exploit would be able at least DOS the AP system.

Any chance someone ripped that old site? Do you remember the URL? I don't have a Ford, just always curious about this stuff.

charm.li covers Fords and many other makes too up to 2013 ish. It is a pirate archive site holding workshop manuals for thousands of cars. Very useful. Very free. Long may it stay hidden. More legitimately, alldata.com has repair data, workshop manuals for most marques up to today and will sell you either single vehicle (called "DIY") or a package aimed at independent mechanics where you can access anything. Same man…

I love whoever is behind charm.li very much- after the bad old days of Haynes manuals and broken PDF links on make-specific forums, it's a breath of fresh air to have one repository like that.

ECU software development is sort of my day job. If you're going to go down this path, I seriously recommend getting the specialized plugs and connectors and making your own wiring harnesses to whatever size you need. It's absolutely easier than manhandling a full wiring harness or cutting one down. Cheaper, too.

The author mentions not being able to get the connector in single digit quantities, seems pretty specialized.

That sorta surprised me. Once I could identify a connector type from a schematic, it was almost never a huge problem getting them in small (1 to 5 piece) quantities. It's mostly a question of finding the right distributor.
