Spn 2000 Fmi 31 - Indexlocal Truck Driving Jobs Craigslistforums Category It has codes spn 639 fmi 14, spn 2000 fmi 9 and 19. I took this readings from the screen on the truck, because i can connect the scanner, but there is no data. Running my bluefire module i get a spn 2003 fmi 31 code in their program. 2003 31 is what i can found online to be a bad communication issue between the tcm and ecm. Common fmi errors from 0 to 21 numbers.
