GM FAULT CODES ON GM H80FT

Checked fault codes on a unit with Check Engine Icon lit. Pulled codes 522630-4 and 522636-4. I have cleared and within a day they have returned. Was also low power complaint. Anyone know what these codes mean?

Ok thanks. That first code was 522630-4 not 603-4 but the last one makes sense. Thanks for your reply.
