2002 Intl 4300 Won't shut off.

@Goodysnap

I recall having this issue on one. But for the life of me I can't recall what it was.


Idm staying poweres up or bad?

Goody might come along and be of better assistance.

 

What engine?

 

Cummings 2007 international 9200 mine has been doing it an having a 2-4 second time before would actually shut off after you would turn key but now want shut down at all gotta pull battery cables off……

 

With that year, you should have an old school 466E square top engine with the single CEC ecm. That should have only one relay to power it. It should be in the fuse/relay box under the hood by the firewall. Should be label ECM Power Module, or something close to that. Ignition power goes into the ECM at a separate pin. The ECM itself turns on this main relay by supplying ground to pin 85 of that relay. You will need to make sure that the relay itself isn't sticking, or wire J97T from pin 85 of the ECM power relay isn't rubbed through on something metal and shorted to ground all the time, causing the relay to stay energized all the time. The ECM itself could be internally faulty, but considered this absolutely dead last.

 

I meant to also tag you. And come to think about it. I belive it was a 2005-06ish that I had issues with. Did that have the IDM up in the wheel well? Been to many years ago.

 

Awesome solution!
