See attached for a definition file in ECU Flash format that defines all trouble codes for your 2012 Impreza (edit: added RR formatted defs too, which include the 32 bit base and can be pointed to directly in RR ECU editor). Once added to the root of your ECU Flash definitions folder (inside of the Subaru Standard or Subaru Metric folder), you should be able to see all DTCs defined. If ECU Flash is open, you need to close it for the new xml file to be loaded. If you have any questions, feel free to ask.
Feel free to send whatever donation you think is fair to
currancchs@gmail.com (PayPal).
You may find the following posts helpful in seeing how I went about finding the DTCs (thanks DSchultz!):

IDA Setup:Entry Point is C0C
RAM Start is 0xFFFF0000, physical RAM length is 0xC000, but enter 0xFFFF.
Be sure to check the box to make the RAM segment.
Leave ROM length and start at defaults
ROM Search Notes:Location of Relevant 0335 (easily searchable string near start of CEL Routine) - 9EBBC
Start of CEL Routine - 9EBB8
Start of CEL Switch Table - 9EAC0
