CUMMINS ECM REPAIR TIPS

[zds]

Hello ZDS,

I have these questions:

1. Your previous diagram showed pins 12 & 14 together, which closes to pin 10 on B connector. Should I separate all three wires?
2. I also see an "open disable signal" wire on pin 3 of A connector going to pin D of 6 pin connector. What is the purpose of this wire? Can I disregard this wire?

Thanks

1. that diagram not mine. yes, you must separate all three wires. look post #67 or 68
2. i don't know what the purpose of this wire. I connected it.

PS 6-pin connector (on scheme) is socket like in the cab, not a plug of diagnostic tool. If represent that it is diagnostic plug (e.g. of Nexiq) you should change places of E and C pins

bench harness..used to calibrated any ecms stand alone

rom boot mode used to calibrate ecm that will not accept calibration in normal mode or will not communicate with service too ...special after get calibration error.

ecm that do not have rom boot mode.

CELECT ECMs, centry and isb dont have rom boot too.

all that is what I had tested.and is just my experience.

Hello! and thanks for sharing. I was wondering, is the purpose of the rom boot switch to connect the 3 wires or is there another connection that I just dont see? Thank you so much for your help!

We couldn't get the rom boot to work. Can you explain how to do it? It looks like the ECM connects automatically when we plug it in, no matter what you do. It doesn't reboot. Thanks if you can help.

The ROM Boot wires have to be joined (ROM Boot button depressed) when the keyswitch is turned on, then release after 5 seconds.
