Those codes aren't the ECU codes. They are codes that relate to the sound system only.
To check the ECU codes you either need to do the paperclip test - or on some of the later ones, and all 3 pot engines, you need a code reader.
The ones which can be checked with the paperclip test can have the codes cleared by disconnecting the battery for an hour.
The Corsa C can be checked with the pedal test.
