I really, really hope I'm not opening up a can of worms. I'm not interested in becoming a "gateway" into Tesla's service docs.
Having said that: there are materials here for both Roadster and S. I purchased a one hour subscription, which is ending in a few minutes. Major sections as follows:
Service Manuals
==========
Service Manual - interactive. An exhaustive list of topics that you drill down into. When you get to a leaf node, you can generate a printer-friendly version. Lots of pictures. How to get at pretty much everything in the car. One interesting thing for me: I was interested in the SIM card. Turns out that you can drop down the bottom of the touchscreen area, somehow, then get access to a "SIM extender", then the SIM. Total time estimated to replace: 0.2 (I think that must be hours). Much less effort than what I'd previously imagined.
Parts Manual - takes a while to load. Comes as a PDF, probably can just be printed off or saved.
Labor Codes and Flat Rate Times
Circuit Diagrams and Connector Reference. Note that there are many versions of these, as changes were made during the production runs.
Service Documents
============
Searchable database of service bulletins and perhaps other stuff. Keyword searchable; also can search by document number, vehicle system; and play around with sort order. The documents that come back are PDFs.
Owner Manuals
==========
I believe this is all stuff owners already have access to.
In conclusion: if you're a service shop, you'll want a subscription for at least a little while and if your business expands to include regular Tesla customers you'll want the year-long subscription. The car's a moving target and you won't want to be operating with documents that are even a year old.
