Motorhome ISB ?

Buddy has a 98 Holiday Rambler with a 275 HP ISB, just replaced his lift pump and still has trouble starting after it sits a bit. How do you check codes on these without a code reader, talked him through the key on-off on thing , but he says no codes or anything odd happened with the check engine light. Did he cook his VP-44?

You'll need a scanner that can access the Cummins data link to pull codes.



Eaton, Cummins, the OTC heavy truck scanners, etc..... IIRC nothing else will do it.

Thanks Dan, kinda thought along those lines seeing as how the key thing didn't do anything.
