What id start with is find someone with the same truck and engine and pull the template from that ECM and write it into yours.

Make/model/engine you have? myself or someone else here may have a template that would work as well as instructions on getting it into the ECM which is quite easy

It’s a 2015 389 cm2350 isx

It’s giving me a 0285 FMI 9 code with about 20 things listed as active.

Essentially anything that is enabled in SAE j1939 multiplexing in parameters in insite it’s showing a code for.

Almost sounds to me like either the cab module is not broadcasting that stuffs properly, or that the ecm has been switched over to use can-buss #2 (instead of can-buss #1) for the truck communications by mistake.


I have seen this situation before as well if someone tried to use a program meant for a Prostar in a Pete 389.. or vice versa.. even tho it was the same exact CPL. Make damn sure that the program matches the exact program listed for the truck on quickserv according to its VIN# and maybe not the engine ser#. Just because a program has the same exact CPL listed in Insite.. does not mean at all that is is compatible with the rest of the vehicle. I have seen that plenty, especially so on CM2350's and X15's.

I recently had to straighten one out for Mr. hag that someone swapped the engine in the truck and did exactly that mistake.

Start by verifying that can-buss#1 is the one chosen to communicate with the vehicle, and go from there.

Next would be to ensure the right program.. one made specifically for a Pete389 of that year/model + matching engine CPL was in it. there are a whole h#ell of a lot of settings that cannot be seen in Insite.. or restored for that matter with regards to this.

just some thoughts.

I.E..>
What is the vin#.?
What is the engine ser#.?
Was the engine ever swapped out?.//.. and if so, what was the origional engine ser#?.
What is the exact make/model truck?.

those are all the things needed to ensure it has the correct program in it.. long before trying to restore the dash settings.
