Now that you have copied the codes.

Clear all codes, and drive it to see if they all come back (this may take seconds - two days depending on cause) .
If the battery voltage dropped off during service or for any other reason, it sets random phantom codes.
There are few things more frustrating than chasing phantom codes.

If this has been done, we can continue diagnosis now.
