648 Glll service code

[br389]

All of a sudden my 648 Glll is throwing a 475 service code and the alarm goes off but it's only on the first pull with it and when clear it out or shut it off and turn it back on its fine.. any thoughts? It happens about once a day..Could it just be an electrical problem? Thanks for any help

OK so now it wants to stall.. I checked inside the motor area and discovered that the fins on the radiator in front of the fan are plugged.. Could that be it?

I think F475 is the engine derate code. What year is your machine? Have you ever changed the ECM or monitor updated.

It's a 2005 and no I have not I just bought it last year

check the plug that goes into the back of the injector pump.  Unplug it and check for broken wires right close.
