Elementary diagnostic tools are free. If you think this is actual diagnostic tools? No. Free? Weird that Tesla offers a subscription for it: https://service.tesla.com/en-US/diagnostic-software $700/year is a strange definition of "free". You seem to miss my point. The OP wanted to pat Tesla on the back for their amazing commitment to freeness and openness. My point was that even if they are doing good/much better now…

No, you’re wrong. I have a Tesla and service mode is free and amazing, I can look at any system and subsystems with it, look at logs, and do testing, all from the built in touch screen all for free. No other car manufacturer comes close. Not sure why you hate Tesla so much and are so bent on spreading false information. Maybe you should help save the planet and get one.

Maybe you should read Tesla's own documentation. The service mode you have is an elementary version of diagnostics. There is an actual diagnostics mode that costs $700/year to have access to.

Again, since you plainly didn't read it: https://service.tesla.com/en-US/diagnostic-software

service.tesla.com - if I'm spreading false information, so is Tesla. Oops.

This is awesome. Curious if these are plug and play and if that's the case where is the memory that tells you what the mileage is. If it's attached to the computer than the mileage would be off if you switch/repair it. Completely unrelated. Would be interested if you figure out how to retrofit the new adaptive shocks on performance models to the older cars. Something I would love to do if I had hobby time. I'm pretty…

You can, at the very least, retrofit the Juniper suspension onto the old car [1]. I haven't ridden in the new Performance yet, but I recently got a 2026 Model Y and the suspension is night and day compared to my 2024. [1] - https://www.youtube.com/watch?v=EahoyTgkkyU

That's awesome, I had heard about the new Juniper suspension on premium models retrofitted. I have a 2022 YP and didn't want to change the ride height so I wanted to retrofit the juniper performance shocks. I plan on keeping the car forever so it might be a thing I try to do in the future since it's likely to fit based on the video you sent. I haven't seen any videos on the performance retrofits. One option is to not have the electronic damping and keep the shocks disconnected, but then it will stay on whatever default mechanical setting there is. I could go with aftermarket of course, but this just really piques my interest for some reason.

Is plenty enough to do full diagnosis on the car. Far better than any other manufacturer does. Give me one that’s better.

Makes you wonder why they sell that, then, huh. Obviously nothing fruitful is coming from further interaction here.

> Turns out that actual cars don’t have individual cables. Instead they have these big “looms”, which bundle many cables from a nearby area into a single harness. This is the reason why I could not find the individual cable earlier. They simply don’t manufacture it. I was really surprised to read this at the end of the article -- how could someone be this deep into a project of this depth and not realize this?! Not o…

When told that they had to have a site for people to order parts, Tesla put up a site that had every single item as "Call us", including the most simple of bolts. And when a f…

Well the AG has a lot of work to do then, because basically all other manufacturers are charging thousands for any sort of diagnostic manuals

GM service manuals for instance are $1,344.00/year.

Ford service manuals are $2,834.95/year.

Honda service manuals are $1,500/year.

Hyundai charges $600/year.

Toyota service manuals are a steal, they only charge $580/year.

> Researchers who find at least one valid “rooting” vulnerability will receive a permanent SSH certificate for their own car It feels like this is something you should get by being owner of the car, and not have to do free speculative research for the manufacturer to get it.

[flagged]

The EU has explicit requirements in UNECE R155 and R156 related to cyber security and software update. A manufacturer will NEVER ever get a car homologated with root access, regardless if it is due to a vulnerability or by design. In fact, if some CVEs are found for your car that allows root access, you have to report this to the authorities and take immediate corrective action. It’s basically the same as if you found the car has defective brakes or airbags.

EVS have actually managed to reduce the number of wire bundles (mostly due to switching to Ethernet instead of CAN Bus)

How? When canbus is already two wires, and by definition, is a bus, so you can just keep stringing those two wires to any module you need. I know Ethernet BUSes exist, but what advantage would those have to canbus then? They're both two-wire buses.

Canbus is much slower than single-pair Ethernet. So you can get more data (more modules connected) over a single pair of wires if you switch to Ethernet.

> The underlying tension is that "you own the car" means something very different from "you own the software running the car." How is this different from the 2000s, or the 90s, or even before, when the normal thing to do with commercial software was to purchase a license to use said software and a physical medium containing a copy? You'd also then not "own the software", but you owned the right to install a copy on y…

In 1990 Ford couldn't turn off your Mustang because you plugged a TwEECer into the J3 port and screwed around with the tune. Best they could do was void your warranty and deny you further upgrades (i.e. tunes flashed as part of a recall or TSB). These days unauthorized access tends to lose you effective use of the hardware you bought because the hardware requires software features to work and that software often unne…

I realize that that's the situation. I'm asking why we're accepting it. Especially on flimsy grounds like "we don't own the software".

If Tesla making the service manuals free is due to the Massachusetts right-to-repair law, then how do other manufacturers (eg: Ford) still get away with not doing so?

I don't think there's a requirement that they give access for free but they are alone i think in doing so. Here in the UK (where i also have free tesla repair manual access) i have to pay a daily rate (there are annual subscriptions available) for other marques and i would say it's not cheap. For example, ford charges me £20/hour or £75/day for access to manuals, wiring diagrams, online connected diagnostics (which s…

Why not use something like alldata.com? Still not free , but much cheaper
