Is there any detailed information anyone can find on what they allegedly did, at a technical level? "Defeat device" is such a broad category of term that it's useless for understanding the details of what it's claimed they did.
The Justice.gov writeup [0] isn't any better.
> The company allegedly installed defeat devices on 630,000 model year 2013 to 2019 RAM 2500 and 3500 pickup truck engines. The company also allegedly installed undisclosed auxiliary emission control devices on 330,000 model year 2019 to 2023 RAM 2500 and 3500 pickup truck engines.
I'd be interested in reading technical details on what, exactly, they did or didn't supposedly do.
