I have a 2012 Subaru Impreza wagon. My inspection is up and it keeps failing emissions because 3 of the computers are coming up as not ready when scanned. I have attached a pic for reference. Has anyone ever experienced this? I’m lost as of what to do at this point.
Failing inspection. Computers not ready?

The Vehicle needs to compete a specific / mixed road test over time and distance.
It is not "computers", it is what the Subaru engine controller monitors and can be called "Readiness Test".
It will take a mixture of city and highway driving to have the ECM (Engine Control Module) monitor and set the multiple tests as a pass or fail.
This is one of a series of tools that I use with Android and Bluetooth, your tool may no have the details but works.\
