CUMMINS ECM REPAIR TIPS

[ddmech]

Zandokan,any info you have on this at all would be greatley appreciated.No matter how small the input.Thanks.

Hi members, please I need your help. A ECM showed a message saying that it lost the communication, then that it's seeded and need to be calibrated. The problem is that after it was re-calibrated it lost all the parameters and I can not figure out all of them, specially the ones from J1939 Multiplexing (unfortunately there is not ECM image), Insite did not restored any parameter or data.
The truck is a 2005 Volvo SN: 4V4NC9TG66N386286 ISX 400. Another issue is that the sticker is peeled from the ECM so I calibrate it with the CPL 8520 that was the one Insite detected. Please if someone can help me with the original ECM configuration of all parameters with this truck, it will be enormously appreciated.
Thanks in advance and best regards.

These parameters are from a 2008 VN with ISX450
I don't know if they are correct for your truck but you can try.
You can tell from your vehicle fault codes which module is missing ECM information, then use Insite to configure that component for multiplexing, it only needs to be enabled for multiplexing and given an address from the dropdown selection. they should all be disabled in the ECM by default, you then need to check for switches, brake clutch CC etc, most times these come from the dashboard or CC, vehicle speed often comes from ABS, sometimes its just trial and error untill you find the correct location.

obviously you can ignore the aftertreatment parameters.

Thanks a lot jctech, Source Address was wrong as well speed sensor was in magnetic when it uses data link.
Thanks again and best regards.

To avoid this in the future you need to upgrade your insite to the latest version,it always saves parameters and restores when ever the calibration is successful.

Why in the insite manuals do they tell you to uncheck the box save features and parameters when recalibrating industrial stationary engines? Do you reload them from the work order image?

Most Industrial calibrations are specific to the machine, for example a QSX15 CPL 2828, 600 HP calibration fr10320. There are 25 calibrations all essentially the same rating but with different features and parameters. The industrial customers are a lot lower volume production, they do not use VEPS to set up the ECM with the features and parameters specific to the machine, some do not even have Insite at the factory (some do not even have service techs with Insite) Each OEM gets their engines delivered with their own specific calibration already in the ECM from the factory or distributor, ready to bolt into the machine, the features and parameters are all set up.

Most automotive calibrations only have 3-4 calibrations for each rating, there will be different certifications, maybe one cal set up for multiplexing, maybe a 12 and 24 volt version, all the truck OEMs will get the same calibration. The truck OEM has to set up the features and parameters to suit the truck the engine is fitted to.
So for automotive (and Power Gen) you use save and restore, for Industrial, Marine and you do not need to,
I usually use save and restore if the machine is working fine, and I always save a work order anyway, so if there were changes made to feature and parameters I can get them back after a recal.

Thanks JcTech
This says it better than any answer i have gotten from any one so far. The book explains it as some kind command that will permanently be corrupted if used during a recal.

Thanks Makura, the funny thing here is that I'm using the latest version but for some reason Insite did not restore the parameters like it usually does. Maybe because the ECM was foot-printed when I calibrated?

thanks for your responses, best regards...

OK that explains it,when you have a foot print there are no parameters to copy.everything goes to 0 even your trip wil be reset just the same as an ecm in rom boot.
