Newer Deere equipment has a lot of components that have to be adapted using DSA - turbo actuators, various hydraulic sensors, various suspension leveling sensors, fuel injectors, interior displays, and anything SCR related are the big ones. Basically, any sensor that needs a calibration step or triggers an emissions code, or a few intentionally vehicle locked modules (ECM).

Interesting. I just finished with a thorny hydraulics problem on a 9870 Combine. It turned out to be a faulty sensor. Part of my troubleshooting involved buying a new sensor, and swapping out each sensor in the system one by one with the new unit until I was sure they were all working correctly. No calibration needed. When i do need to calibrate a system i can do it all from the onboard computer.

What a systemic downgrade in capabilities.

Yeah, that’s a good way to summarize what people are mad about; they basically moved all of the calibration from onboard to offboard diagnostics, and then thwarted most efforts to access the offboard diagnostics.

Automotive is similar and I’m a bit worried for EVs; for ICE autos there’s enough emissions related regulation that some diagnostics and manuals are accessible, but for EVs there’s nothing much stopping a Deere style complete lockdown.

Exactly, go look at Lucid/Tesla and a few others for examples of how the car is a brick without the manufacturers sekret unlock codes and calibration software. If they decide not to help, you are out of luck.

Ah but you didn't buy the car, you bought a license to drive the car. You know, like CD or Playstation game.

Until some kind anon hopefully leaks it...
