They'll provide "tools and manuals". If this includes service software that is good. Also I wonder what kind of detail is there in those service manuals. For the mechanical components I would at least expect drawings of each assembly showing every gear, every seal, every clip with spec. For electronics I would expect at least board view files if not schematics. Do I believe this will happen before it is law to publish it? Not really.
When finally those laws get proposed I fully expect manufacturers to claim "security and IP theft" exceptions and politicians will fold. I still have electronic equipment made in the 80's that had not just schematics in its manual, but pcb layout drawings so you could remake a pcb if it got destroyed... And somehow we didn't have clones of this equipment appear.
While I agree with you that companies should provide sufficient information to enable consumers to repair their products, I think considering the complexity that goes into manufacturing mechanical components and fabricating circuit boards, it would be a long shot for many consumers to repair equipment on their own.
Hobbyists/industrial outfits would be a different story as they would have in-house expertise....
Are they worth to buy for modern/semi-modern cars? I think I owned one for Peugeot 106 2002. There wasn't that much really useful stuff in it No detailed exploded mechanical drawings of all parts, just drawings showing major assemblies and selected parts.
Then I bought some "service manual" cd on ebay and there was everything there. Even estimates how long it "should" take to replace specific parts.
I doubt it, I don't have one for my early 2000s vehicles but for my early 90s vehicles it's a boon. I think they stopped printing and moved to online. Perhaps it was an IP fear that led to them getting less detailed?
But the 1991 Nissan Patrol manual for instance doesn't show how to reflow your injectors. It does however indicate you can use a fish scale to measure the force of the throw for the steering swivel hub so you can decide if you need to add or remove shims from the king pin bearings. Rebuilding this hub and even the diff is described.
