CUMMINS ECM REPAIR TIPS

[peter21]

I have 2 footprinted Celect Plus ECM, and I'd like to make a ROM boot harness.

Can someone please share how this harness is wired?

Thanx much.

Look this, ZDS member make this schematic. Well guys the first scheme was bad elaborated, but this if it works to 100 %

Thank you Peter21.

Do you also have ROM boot procedure for Celect Plus ECMs?

Thanks again in advance.

Look here, in post #59.

peter21, thanks. you finished my schematic

[peter21]

peter21, thanks. you finished my schematic

you're welcome my friend. I thanks you too for having done the scheme, only needed the rom boot.....

peter21, I think there must be 3 separate wires from 10,12 and 14 to button 1, don`t I?

[hercamp]

just make a joint ..before turn ignition on...and separate them ...after 5 seconds ...thats all

Hello ZDS,

I copied your ROM boot cable and tried it out. I am not able to communicate or calibrate footprinted Cel+ ECM.

Have you tried this using this harness setup?

Thanks much.

Poptest, i tried it, and it`s works
but I have spent a lot of time to connect it correctly. draw attention for marks on connectors (On the scheme they are represented not as you look at them, but in mirror image)

Hello ZDS,

Your drawing shows a +12v unswitched battery connection to pins 20, 21, 22, & 23 on Actuator harness C. I only made a single connection to pin 22 because these 4 pins are internally connected inside the ECM. Could this be the cause of my problem?

Today I will connect them all like your drawing shows and try again.

Thanks again.

hello friends .. I'd like to make a ROM boot harness. for isx cm570

Can someone please share how this harness is wired?

Thanx much.

yes ZDS you're right, there should be separate. Thank you for the observation........ now the scheme is complete.....

and the procedure for have boot in the ecm is as my friend hercamp said..... "just make a joint ..before turn ignition on...and separate them ...after 5 seconds ...thats all".

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

servando, mondao
look this. i made scheme, but it is not finished. it is without Rom Boot button. i don`t know what pins must be connected to Rom Boot
maybe hercamp helps us again and will say what pins must be connected

PS this scheme for ISM and ISX cm570. first i was wrong and made for ISM cm570, but when i was start making for ISX i observed that them are same.
