On our way home from Florida we got the dreaded "check engine" light about 60 miles from home.The coach is running good and all fluids are good ,temps are good, but the code on the LCD display shows an SPN 3474 FMI 31 code in the diagnostic readout.
The Cat Hotline says the code is a failure to ignite code and I probably have an issue with the ARD and/or regeneration function of the C9 engine I have.
I scheduled an app with the local Caterpillar shop for Wed and I was just trying to find out as much about this issue as I could before I get there.
I know there have been issues with this engine and the turbo and ARD head were replaced in June 2013.
What experience have others had lately??
Anything that might help me at the repair shop??
Thanks,
Dan
