90% of problems on modern cars are computers miscommunicating with other computers, out just deciding that some sensor isn’t behaving well enough, so you have to throw the baby out with the bath water. All this in proprietary formats in proprietary subsystems a filthy mortal like you can’t afford the tools to even know what’s wrong.
And then you can get 3rd party tools like Autel, which also aren’t cheap. But this model of tool can only talk to these modules on this model of car. Any car that requires a scan tool to bleed the brakes can go straight to the crusher. Oh and let’s run all of the buses through the radio so you can never change that out without a dongle to try to keep things working.
How do I read the knock sensor info from OBD port for Subaru
A: It’s not part of the OBD standard, so you need a Cobb access port to read the data
Okay but I don’t have money for that and I’m literally just making a python script to do this.
A: Well you need the custom ID to query the sensor info
Okay what’s the custom ID?
A: You have to pay morbillion dollars to get access to the documentation that has the custom info that you can get from the ECU
Not even close to doing anything with tuning ot modding, but you’re telling me I can’t even read a sensor because neither Subuaru nor Cobb will tell me a single hex ID bruh
I just wish I could but a fucking service manual. Seems like like the only way is to get access to a digital copy through a subscription service. I don’t need service manuals for every car made, just mine.
I like to work on cars. Behold modern cars and all of their overcomplicated bullshit.

I really hope that right to repair at least makes the hex IDs available

I’ve kind of used it, but I’ve found a lot of service manuals for my cars on enthusiast forums.
I managed to find a PDF for my vehicle. But I would much rather have a physical book.
Oh believe me, I know. I’ve printed out hundreds of pages to put in a binder when I did my transaxle rebuild.
My trick is buying the paper with the 3 holes already punched. But almost any print shop should be able to print and bind it for you as well.
I have started a binder myself. The idea for the paper is real good. Thanks.
