Daf multi warning

I was out in our 06 Daf CF75-310 is started throwing up all kinds of messages, engine fault, low oil pressure, alternator fault, starter overheating, transmission warning and so on, nursed it back to the yard now it will not start, any thoughts please

One of my 105s and a cf did something similar and it was just 2 relays that needed changing its a common fault daf knew what it was straight away.
