Silverleaf, engine fault codes

[smlranger]

UPDATE: Well, the 'check engine' light is back along with engine de-rate and the 'low fuel pressure' error code on the Silverleaf. This time I noticed that while this fault occurred, my electronic odometer got goofy..... it just displays strange characters. I have had this same display intermittently several times with no check engine light but now I wonder if these two issues are somehow related.

If I take it back to Cummins, it will be working fine of course .

Goofy computer display that is intermittent points toward power supply.

Did it run different while error displayed?

Look for loose or odd connections either in connectors or grounds.

If engine was fine but silverleaf stated otherwise then look at dash area for poor ground buss connections.

Get an auto headlamp for test load and test ground buss to battery hot to see if it is good.

Engine was not fine.... when you get a 157 (559) error code the engine ECM thinks there is some problem with fuel delivery so you get a 'check engine' light and a significant loss of power. Based on the VMS history, this error code has occurred many times but only recently did I notice the goofy odometer display occur at the same time. I suspect these are two unrelated issues but was looking for any and all possibilities.
