Hi guy's, I'm here at work and we have a sweeper in the shop with the 24v ISB cummins. Hooked up the lap top to it and ran the "ISIS" read it, under the data sheet in the VP44 section there is a fault code "12", thats it. No "p" or description of the code and we can't find it ni any of our books or the lap top. Do any of you know what that code is? Thanks for your help!

New info..... New code is vp44F "Fuel pump statous. And a 4 when running, 12 when not running.

 

Call your local Cummins dealer. They will know.

 

LOL, We did, they are in the process of trying to find out them selves! They have no idea. I thought I might get a quicker awnser here.
