Farmers Struggling With High-Tech Farm Equipment
An anonymous reader writes: Farming is a difficult profession. One of the constants throughout the generations is that if you're working out in the field all day, machinery eventually breaks down. Farmers tend to deal with this harsh reality by becoming handy at basic repair — but that strategy is starting to fail in the digital age. Kyle Wiens, founder of iFixit, writes about the new difficulties in repairing your broken tractors and other equipment. Not only do you often need experience in computer software, but proprietary technology actively blocks you from making repairs.
"Dave asked me if there was some way to bypass a bum sensor while waiting for the repairman to show up. But fixing Dave's sensor problem required fiddling around in the tractor's highly proprietary computer system—the tractor's engine control unit (tECU): the brains behind the agricultural beast. One hour later, I hopped back out of the cab of the tractor. Defeated. I was unable to breach the wall of proprietary defenses that protected the tECU like a fortress. I couldn't even connect to the computer. Because John Deere says I can't." Wiens also tells us about Farm Hack, a community that has sprung up to build a library of open source tools and knowledge for dealing with high-tech modification and repair in agriculture.

This isn't actually the case. I know of no Federal regulation that disallows adjustments by a particular party. All that the regulations require is that there be no unauthorized modifications to the system. They don't place the onus on anyone to prevent such modifications in any particular way.
A successful API design takes a mixture of software design and pedagogy.
Dongles are cheap. The information they give you is fairly useless in diagnosing specific hardware faults, sensor codes, etc unless you have the factory proprietary software.
Want to modulate the ABS module to purge air and replace the brake fluid? Sorry.
Want to see which wheel is giving you the TPMS low pressure error even though they are all properly inflated? Sorry.
Want to see specifically why a code is being thrown that disengages the AWD? Sorry.
Well, sorry for me unless I get a Tech2 scanner maybe for $1500 used, or $4000 new off fleabay.
