They can make the engine run but without salvaging data from the old ECM it becomes a $175/hour guessing game. Cummins has no idea of what your coach parameters are.
CUMMINS ISX CRUISE CONTROL NOT WORKING ISO
I was able to get the ECM ISO programming file from another coach exactly like mine.
Cummins Coburg originally did the programming for Monaco Oregon but they changed their computer system and erased all of those old files. That includes Cummins Corporate, Monaco Rev Group Coburg, Cummins Coburg etc. When I had an ECM issue there was no one that had the programming. I would want confirmation by a highly skilled Cummins tech before I started sleeping good at night again. There isn't a chance in hell I would drive out of there and call it good and think I am good to go. I highly recommend that once you get things set you schedule an appointment at a good Cummins facility and have them go through all the parameters and be sure nothing is messed up. A tech who does not have the experience and starts screwing with parameters in an ECM can create headaches for you - improper shift points, higher fuel burn, etc. This is why I have always said never let anyone screw with the parameters of an ECM unless they are experienced cummins techs. Pac/Jake Brake operation, transmission shift points, engine fuel burn are just some of the critical parameters controlled by the ECM. People do not realize that the ECM is the brains of their coaches.
CUMMINS ISX CRUISE CONTROL NOT WORKING SOFTWARE
Even then it should have been a simple upload of the software to get things right again. Or it could be the previous mechanic really screwed things up. I do not know if your shop is lost on this issue or are making it harder then it has to be. Maybe I am missing something here but all the ECM change outs I have seen or heard of was a fairly simple process. He is the only one on this forum that I know who has the experience of setting paramaters and working with the software on a Cummins ECM. Thanks for taking the time to read this and God bless you all! With the Covid thing and our efforts to complete rebuilding from Hurricane Michael from 2018, we'd be fortunate just to get the coach running with the hope of getting back out on the road again for a weekend or twenty! FIve-Star is convinced they should have it and will attempt to follow up with Rev tomorrow on this last issue. Unfortunately, he failed to source the ACM parameters and we are now looking to see if anyone may have the source addresses for the engine brake (exhaust brake, not Jake), all cruise control functions, service brake switch and the park brake and other functions that would be helpful.įive-Star is also looking for the rear end ratio and although we tried to get any and all information available for our unit from Rev, they claimed they have no info at all.
He left the new one in as I understand they return the old one to recover core charges. The previous mechanic replaced the ACM in an effort to resolve any issues that may have been caused by faulty program parameters. Last mechanic crapped out on us and said he could not resolve it so we took the unit up to Five-Star Freightliner in Dothan, AL and the managed to resolve what turned out to be leaks in the fuel rail.Įveryone up there was great but it seems our passion for these older Monacos means nothing is that simple. Karen and I are still working on getting the 2008 Diplomat with the 400ISL, Allison Transmission and Roadmaster chassis fuel system resolved.
