If it’s software, you could just reinstall it.
Hardware would be a different story. But I’m not sure how that’s different than today. My friend has a RAV4 that he’s added several hardware hacks to. For example, there is a module you can add that will give you actual numbers for each tire’s pressure instead of the usual warning light that a tire is low with no indication of which one. It even shows up as an extra screen on the normal interface between the gauges.
