Many years ago I had our coach worked on. Following the service the Silverleaf started throwing a series of code failures, but the engine was running fine! I also noticed numerous wire harnesses were drooping back by the service panel... When I climbed under the coach I found that the service techs had cut the wire ties when servicing the coach. I redressed the wire harnesses, secured them with wire ties and "POOF" the coach stopped throwing codes! Oh, and I found a new service center!!

Probably spurious due to wiring problems or sensor. When I first got my Silverleaf I was throwing similar codes but my engine was having some problems so when I replace the crankshaft sensor all the spurious codes went away.

Later when I changed my lift pump the spurious codes came back so now I have to go back and reseat connectors and tie wrap my cables from moving and that should do it.

Go to the Cummins site and get a login. On that site it has a converter for converting the Silverleaf codes (SPN/FMI) to Cummins fault codes and provides procedures for repair.

Your problem is probably loose wire or sensor.
