I purchased a Cat 320DFM second hand and the previous owner doesn't know what the password is for the in cab monitor. Is there a default password that will let me in to the basic functions of the monitor? And can I somehow reset the 'lost' password?

You will need cat ET to reset the ash and soot load. The ecm doesn't know that you replaced all those parts until you tell it.
