Check engine light

[Volvo8873]

I do get that display icon on my 2005 Volvo D12 when I hit the switch to prime the fuel system after a fuel filter change. Always thought it meant that it was a sign that it was purging the air from the fuel system. But what do not know... I never do get a code from that and I have PTT software to look for one also.


EDIT:

I am 99.8% sure that it came on also when I changed my main filter out on my 2011 Volvo with 2250 ISX. It came on automatically when I turned the key on to prime the system. I have only changed the main filter once since owning the truck and it was last February. It has been parked for the last 6 months. So I am a little vague on remembering it.
