Here you go
P0171--System to lean on bank 1
P0420--Catalyst System Efficiency Below Threshold (Bank 1)
p0430--Catalyst System Efficiency Below Threshold (Bank 2)
p1000--Monitor test not complete.

It sound like either catalytic failres or oxygen sensor failure. Did your friend recently have any exhaust work performed???
