Engine and transmission service message! 2003 xc70

[Dempsy]

First I try to start my car and it stalls and then turns over but does not catch so I leave it for awhile and then it starts but flashes 2 messages, service engine and service transmission!! what is going on.
Thought at first it is the fuel pump or relay but why would it start and flash those 2 messages?? just bought the thing. rrrrrr
going to hook obd 2 reader from buddy up to it but dont know if it will read the codes.
It did not have any messages till it fully started.

any ideas????????

a U0073 is showing for a communication module on the code reader. Dont know what that means

Possible dead ECU, but i'd check all the fuses and connectors first

U0073 is a code for CAN network offline.
You need a VIDA or Autologic scan of the vehicle to see the full codes.
Generic code readers will not show all the codes from the modules.

taking it into a volvo specialist in 2 hours and he has the fancy reader so I will hold my breath till then. Second volvo in 3 months and I'm losing my faith. Maybe I should have bought a domestic. Ya i said it
