The engine ecm has failed on a cb 24 b roller I am working on. Cat can't find one anywhere. Does anyone know of a company that might be able to repair this one or maybe have an aftermarket one for sale.
Do you have a Part Number for the ECM you’re looking for.? If not post the machine Serial Number and I can look it up.
the part number is 439-0291 . thanks for looking
Are you positive it has failed? How was this determined?
i followed all the diagnostic procedures, twice. double checked the harnesses and all the connectors. then had Cat field service come out and check it again. They confirmed what i thought and said the ecm is not responding.
439-0291 was replaced in 2014, first by 444-7918 and finally to the latest number 478-1711. I assume the last number was the one the dealer was trying to source for you. Unfortunately this module is only used on a couple of C1.5/C2.2 industrial engines and small compactor engines like yours, that's why it is apparently so rare. I can't see one anywhere.
Thanks for looking, I guess its just gonna be a wait until they find one.
I've put a few requests in. Have to wait and see what the responses are.
just to follow up, Cat dealer found an ecm, installed and flashed it. Machine is up and running.
Glad you finally got sorted.
