You’re talking about the “Right to Repair” act which is a pretty divisive issue in the automotive community. It’s impossible to properly maintain and repair a modern car without extensive service information and access to manufacturer software and technical bulletins. The $100 code reader and so-called scan tools and gizmos that geeks plug in under the dash are nothing like the diagnostic and repair systems that professional competent shops use.
On the face of it, Right to Repair seems to have the public in mind, giving access to service and repair information to the DIY motorist and the independent shops many people use. In other words, you or your favorite independent shop would have access to everything they need in order to properly maintain and repair your car, as opposed to being “locked out” of the system forcing the driver to take the car to the dealer.
The problem with this is that none of the above is true. All the equipment, service info, and software updating (aside from safety recalls and a few things from Euro makes) is available to anyone anywhere anytime. No one is locked out of anything. When your local garage complains that they have to send your car to the dealer because they’re the only ones with access to the equipment, they’re wrong. It’s just that they haven’t bought the right stuff.
When a guy bought a new Oldsmobile in 1965, he could buy a tool set, order a complete factory service manual and go about maintaining his car from day one. He didnt get the wrenches and manuals for free–he had to buy them. The same is true today, except now we’re talking scan tools and software. “Right to Repair” would have carmakers giving the stuff away.
