Dash is displaying code SPN#3695 FMI#9, my books dont show this code anywhere, can anyone tell me what they are? Thanks.
I have a 2009 MRU, I'm having problems with a code that comes up (MID 128 Engine ECU, SID 232 5 volt supply, FMI 4) Inactive #19. The ecm and wiring harness has been changed, and we are still having the same issue with the same code. The truck will run fine for a day, the the CEL comes on and it goes in Derate. We have taking it to dealers and 3 party shops with no luck. Anyone have any suggestions?????
