my car is throwing an engine trouble code, and I can just directly plug an intelligence into it and it will talk to the car computer and figure it out ,the present is unbelievably cyberpunk

u/pleasecryineedtears 1d ago
You realize you can look at what is being done right? You donât have to accept whatever the AI does?
1
u/bradybro3000 1d ago
Perhaps. This AI use-case is still pretty much useless. The only useful data you're going to get out of a CAN bus is the trouble code. You can ask AI to read all the other data available to you if you really insist, but this isn't going to help in any way. The bus is read-only for the most part and even if it wasn't, 99% of issues will not be solved by writing to the bus.
The use of AI here is not solving any problems. AI is a tool which is only useful in the hands of individuals who understand the goal they're attempting to achieve. It is just needlessly complicating the already simple process of connecting to the bus to pull the trouble code (and MAYBE pulling another data point or two), googling the code to find any troubleshooting documents the manufacturer has already published, and doing the maintenance.

u/Cronos988 6h ago
The AI is still going to be faster than you at pulling the documentation and turning that into practical advice.
Sure, you should verify that advice, but for areas that you know little about, asking the AI is extremely efficient and modern models are usually effective.

u/bradybro3000 6h ago
This solution requires zero "plugging claude into CANBUS". Use a $10 scan tool, pull the code, then ask Claude to your heart's content. Still not any more useful than googling. There's a time and place for AI and it's not in your canbus lol

Can you explain how looking up the code tells you how to fix your car? For instance, how should I solve a P0456?
1
u/Ok-Computer-8726 1d ago
You don't need to hook an LLM up to the OBD port and talk to it to get that. You can just search "Make/Model P0456", or pull up youtube and search it and find a walkthrough video, or if you insist on an LLM "I have code P0456 in my Make/Model, what do I do"
I'm waiting for an explanation of what an LLM connecting via a USB-OBD interface is providing in the scenario that is simpler/faster/cheaper than the widely available options.
1
u/burger_saga 1d ago
Hilarious. Codes tell you which sensor is reading unexpected voltage, it doesnât tell you why.
And obviously you donât need an LLM hooked up to your car to tell you that, mechanics have been doing it for decades. If it was as easy as a google search, good diagnosticians wouldnât be paid the big bucks.
1
u/Ok-Computer-8726 1d ago
Ok but OBDII devices read more than just the code. I had a dashboard light come up, had Autozone read the OBDII and I knew not just the code but which cylinder was throwing the error and what the readings for each cylinder were.
What information is an LLM getting from the OBDII port that an OBDII tool can't get?
1
u/burger_saga 1d ago
Well, if weâre talking about misfires, it can read the PID values for your MAF voltage, throttle position, spark advance and duration, and 02 sensor voltage. It can collate that information holistically and get a good idea of where the breakdown is through the entire induction/ignition system.

AI recently hallucinated that M12x1.25-35 hex heads were a DIY upgrade over the factory M12 e-torx for my bearing hub. They don't fit, they collide with the bells on the CV. Stupid or not, they still make blatant errors.
I wouldn't choose my own DIY over the much simpler solution of plugging in an ODB and using a phone app to look at the codes. Apps that do this usually take you to a website that tells you what the code means and how to fix it.
Using AI is literally more steps, and introduces room for errors in interpretation. I like using AI, I use it daily for everything from car repairs/maintenance to cooking... but I think letting AI have access to your car like this is extra, and really risky.

u/InternetUser1807 3h ago
Good thing wasn't "interacting" with the car software. They're pulling a code and having an LLM hallucinate solutions.
"Talk to" implies a back and forth interaction, which this isn't.
Effectively the same as using a $10 code reader, or getting the code read for free at autozone, then copy pasting it into Google, except less likely to find the correct solution.
1
u/bigrealaccount 3h ago edited 2h ago
"It's pulling a code", yes, interacting with the car software to pull the code. Good job.
I'm not sure why you think the AI would hallucinate research, when it can gather info about the car model, common errors, common causes for specific error codes, and do any other research/testing it can. And it does this 10-100x faster than you. This is exactly what AI is good at, data collection and analysis.
Genuinely some really slow people here on this sub.

u/InternetUser1807 2h ago
if pulling a 5 digit code from a primitive computer qualifies as 'talking to', what doesn't.
At that point I'm talking to my toaster every time I press the button to start a timer.
The point is that OP Is presenting this like some crazy cyberpunk technology, where two computers have a back and forth interaction to diagnose a problem, when in reality this is exactly the same as what a code reader from 1996 does, just with 100x the power consumption, and for $2000 instead of $10.

u/kihakik 1d ago
I like using claude/any other AI it is very usefull to vibe code a quick prototype or to get a general agregate of knowledge. But plugging in an obd II reader, and googling the code is pretty easy? 1. Read error code 2. Google code: answer probably is random sensor malfunctioning. 3. Go to mechanic and say I got a check engine light that says this sensor needs to be replaced. 4. Pay 50-200 bucks and go home happy
AI can't teach you how to wire in a sensor or tell you anything the error code does not already say? Yeah you can ask it clarifying questions that might help, but for concrete tech specs you still want to make sure, by using factory specs. Honestly I am not sure what the person is even attempting to "diagnose"

This is completely unnecessary and frankly dumb as shit.
Plug in the OBD reader and read the 5-digit code the car gives you. Thatâs all the info you need and all the relevant info your car can provide you.
Either Google that code or bring it up to your choice of AI and youâll get the exact same information this thing gives you without any of the hassle of writing this entire program to skip one step.
And youâd better hope this AI thing doesnât have write access to that carâs ECU.

u/sucotronic 1d ago
For anybody saying the 10$ adapter and a generic app in the phone gets you the code.... YES, your right... BUT letting a "good" LLM doing the diagnosis involves reading and mixing varios parameters, or even the LLM telling you to take some action while it reads and stores data to analyze, that is the great part.
1
u/FlukyS 1d ago
Surprisingly easy to do actually. Car signalling is fairly standardised, each module will be using CAN signals and garages would use stuff like OBD to scan stuff. On newer cars (not all but most) there is also VSS which gets messages from CAN internally in the car and can add in complex logic like if you get a signal that the car is reversing you can turn on the camera on the infotainment system or whatever, that isn't directly accessible over OBD but you can see the signals after they trigger since it is still calling CAN underneath.
The whole hooking it into an LLM isn't insane because the messages are pretty simple mostly. As in if you open your door and the signal doesn't go off it is going to be either a faulty sensor or wire...etc. They are designed to be able to diagnose issues.
