Does anyone have a good list of the pre 2003 Isl 400 ecm codes. I have checked the online google sites and can not find a decent list. I run vmspc and my rig showed a half dozen codes in a 5 min time line. None of them are in the list i can find online. I took coach to coach care cummins and they checked it and think they found a bad ground connection at the front elect run bay. They checked and then cleared all codes and told me drive it awhile and see if any come back.

Different issue does anyone know the pid to get the real oil pressure and not a constant 55 lbs? I called silverleaf and was informed that it is a cummins ecm issues until about 2008s and it is really a on off value and they just use 55 as a its ok reading.
They told me that my codes are PROBABLY a result of a floating electrical voltage ( bad ground usually) and correct ground and drive it and see what it reports.

thanks

I can't help on the codes, but my VMSpc gives my correct readings on oil pressure on my 05 ISL. It idles at about 30 and runs up to around 60 while driving.

My 07 Neptune with Cummins isb engine always reads 55.0 or 55.5 lbs. pressure according to scanguage D. I'm curious to see what others may say would cause it.

Tech at silverleaf tells me that the pre fuel rail isl and isb ecm just put out value of 55 if there is more than 5 lbs oil pressure so the stop eng light does not come on. The dash oil guage has a separate sensor and it does not route thru the ecm

That's good to know I figured one of the oil pressure sensors was kaput. Thanks for the info.
