Ecam actions I would perform as pnf are:-
Announce failure
Look at SD to confirm failure
Having confirmed failure and with no action to perform press Clear pb having coordinated with pf
Review Status with pf
Review Inop systems with pf
Press Clear again to return Ecam to normal operation
Then consult QRH/FCOM as appropriate.
Resume normal comms handling as pnf
I always believe that the word CLEAR has two meanings with regard ecam handling.
The first is that the pf has understood what the failure is and that he is aware what actions have been performed(Al ist klar) and secondly to remove the failure on ecam.
