According to records filed in the case, Achtemeier conspired with mechanics in garages and operators of truck fleets to disable the anti-pollution software installed on diesel trucks.
Coconspirators who wanted to disable their trucks’ pollution control hardware system—a process commonly known as “deleting”—sought Achtemeier’s help to trick the truck’s software into believing the emissions control systems were still functional, a process known as “tuning.”
Monitoring software on a deleted truck will detect that the pollution control hardware is not functioning and will prevent the truck from running. Achtemeier disabled the monitoring software on his client’s trucks by connecting to laptops he had provided to various coconspirators. Some of the coconspirators would pass the laptop on to others seeking to have the anti-pollution software disabled on their trucks. Once the laptop was hooked up to the truck’s onboard computer, Achtemeier could access it from his computer and tune the software designed to slow the truck if the pollution control device was missing or malfunctioning. Achtemeier could “tune” trucks remotely, which enabled him to maximize his environmental impact and personal profit.
Manufacturers try really hard to stop their proprietary software from getting out into the world, because when it does this is exactly what happens.
Case in point: I have a $35 phone app that lets me change software configurations on my BMW, and it is great. Can’t change anything related to engine, aftertreatment, or safety though…which is a good thing.
Flipside of this coin: this results in repair monopolies because users cannot repair their own vehicles and equipment and manufactures use this exact excuse to claim they HAVE to run a monopoly cause the EPA. Literally John Deere has said this.
In truth, illegal vehicle mods have been and will always be a thing. Manufacturers should still provide all the tools to users to repair, and emissions checks on trucks will have to be smarter to catch cheaters. Make the penalty for a deliberate violation (willful not accidental) so egregious that no one would consider it, even if it saved 50k+ per truck.
100% - I started writing a second paragraph about John Deere’s fuckery, but deleted it. You are spot on.
