Seems good but unlikely to accomplish anything. Manufacturers obviously don't want to make third-party repairs easier because they think they'll lose money, so if the EPA says one excuse isn't valid anymore they'll just find another one. This new guidance doesn't ask or even suggest that manufacturers actually do anything, it just says "hey if you want to help your customers repair stuff, we'd be ok with it".

As long as the manufacturer isn't on the hook for a violation of the EPA when the owner modifies their vehicle to be out of spec.

For automobiles, this has been the case - that the owner is responsible the vehicle goes out of spec... and the owner can also do a lot of customization of their vehicle.

For heavy machinery (which tractors fall into), the manufacture is almost always on the hook for any modification that the owner makes.

> Here’s one real-life scenario that Natalie Higgins, vice president of government relations and general counsel for EDA, shared during a recent presentation for the United Equipment Dealers Assn. “An Ohio equipment owner purchased a tractor and then installed a turbocharger on the engine. The tractor owner sustained injuries and then sued both the manufacturer and the equipment dealer, alleging that his injuries were the result of negligence on the part of the manufacturer and dealer. Remember, neither the dealer nor the manufacturer were involved in the turbochargers installation.”

> And, if you service equipment that has been chipped, the warranty will most likely be denied and you will not be paid for your work. “That can also put your dealership in a sticky situation if technicians in the shop are not conveying to the rest of the dealership what is going in,” says Wareham.

> Financial consequences can be harsh for not following the law. Under federal law 40 CFR § 89.1006, the penalty for a dealer who removes or renders inoperative emissions controls is subject to a penalty of $32,500 for each violation. Wareham says that one manufacturer of chipping software was initially fined $300,000 by the EPA and then $6 million to ensure future compliance with the Clean Air Act. “The EPA has stated that their intent is to crack down on defeat devices in 2020,” says Wareham.

> A dealer may face liability issues when customers tamper with the equipment they purchased, even if a dealer had nothing to do with the modification. For example, in instances in Ohio and Oregon, customers were injured as a result of modifications and dealers were sued.

This kind of do nothingism come up any time something will happen, perfect is the enemy of done.

Exactly. My understanding is that the manufacturers interpreted the clean air rules as conveniently requiring them to use digital restrictions management (explicit or even just tacit) to prevent tampering (aka repairing) your own equipment. Low-emissions diesel engines then get hated on for the "EPA requirements", with the immediate bad actor corporations sidestepping blame (as usual). Removing the initial motivation / excuse isn't going to get rid of those digital restrictions, openly document the systems, nor provide the tools required to work on them.

The way this is framed, it doesn't even sound like the goal is to affect this dynamic at all. Rather it's to create a loophole of "temporarily" bypassing emission systems, such that if you delete and get caught you can just pinky swear that it's temporary for a repair that you're about to complete real soon. So the only real goal seems to be implicitly rolling back emissions enforcement across the board.

Actual right to repair action would focus on making it so individuals are able to self-repair the emissions control systems to function as designed. So this really just seems like yet another instance of a lofty idea being abused as cover for the destructionist agenda.
