ISM Fault Code

[Lug_Nut]

This morning, 29 degrees F I had a breif fault code, then it cleared itself. I'm wondering what exactly the fault was. The code, read on the service panel was "Source 0 SPN111 FMI18. Anybody know what this fault is?

We run an 08 4502 EX w. a Cummins ISM and can't wait to hear what that fault code was for. No,..we haven't experienced the same code, and are now pretty much out of winter's way down here at Wilderness RV Park in Silver Springs, Florida, but always wonder about all those coded fault messages that folks encounter.

By the way, where are you guys experiencing 29 deg./F?? Where ever it is, ya gotta "get outta dodge" and head er South......WINTER IS COMING !!

Think it means low coolant level.

Hi Steve, We were in Merritt British Columbia, in the Canadian Rockies. We are now in Burnaby, kind of a suburb of Vancouver BC.
Doug, that makes sense, it could be low coolant. The fault code would clear as the heat increased and the coolant expanded. I will top it up and post any changes.

Thanks guys.
