What year is your HS250h and how many miles? What are your symptoms?
You should Google search the word Toyota plus each of the codes listed above for further clues.
If you have a 2010 have you had the transmission replaced per the recall?

No, however you should first check your 12 volt battery as when it gets weak it can cause lots of different warning errors.
You should also try a Google search on those codes. However, the codes are just a map that leads to what is maybe causing them. What is the year and mileage of your HS? https://www.google.com/search?q=code...hrome&ie=UTF-8
Sometimes you really do need a professional to run diagnostics. I suggest one of the https://www.thehybridshop.com/locations
or a Toyota specialist. This is the same engine and hybrid system as the Camry.

Never go to the dealer with a 12 year old car, you are asking to get raped. Find a good independent import specialist. I suggest you look at the recommendations in this link. It contains recommendations from listeners of the old NPR car repair radio show, Car Talk. You can search state and town. https://www.cartalk.com/mechanics-files
