Tree98 is right.


Johnny LongRifle, ... I think the issue is that you do not have a full grasp of what needs to be done.

First and foremost, a used ECM is not a good idea. Is it even the right part#?.. and is it an exact replacement for the engine ser# that you have?.

(assuming that it is for a moment)...

- There are TWO things that have to be done (flashed in) to ensure everything is right with the programming in the ECM.

A)> The base program (from cummins) that needs to be flashed into the ecm needs to both match the serial number of the engine, and also be compatible with the the vehicle. This can be found on cummins website, assuming it is the original engine (based on the esn#) that belongs in the truck. The programming is not a willy-nilly crap shoot, it needs to properly match both the engine and vehicle type.

The correct base program WILL contain important vehicle-specific settings like general J1939 communications options like buss speeds, connectivity, etc. - It will also have proper offsets for vehicle intake and exhaust piping sizes, and other major things, but not any specific dash button addresses, etc.

So .... the base program WILL NOT contain the vehicle-specific settings like button addresses or settings for ruise control, engine brake, brake pedal, A/C input options, and other connection info for communicating with the dash, buttons, pedals, etc. Those are vehicle-specific adjustment settings and are NOT part of the base programming itself... which leads to B...


B)> The VEHICLE-SPECIFIC ADJUSTMENT SETTINGS (some of which you see in insite as 'features and parameters') has to also match the vehicle. THESE ARE NOT PART OF THE BASE ENGINE PROGRAMMING FROM CUMMINS! ... and are installed into the ecm separately. - ONLY THE VEHICLE MAKER/DEALERSHIP HAS THESE SETTINGS... NOT CUMMINS!. - SO, if they get lost or corrupted, etc.. then you have to take your ECM (or vehicle) to a dealership to have them put back in/restored. You can guess and try to adjust them with Insite, but some settings may not even be showing up.. and it can be VERY DIFFICULT to figure them out if you don't have a previous back-up of them.

So.. like others have already said ... take it to the vehicles OEM dealership and let them restore the proper programming + all of the proper vehicle settings from when it was built, and the problem is solved. Many times, that is someone's only choice if those vehicle-specific settings were lost or corrupted.


After that, and after everything is working properly again ... use your Insite software to make a fresh 'work order' and 'ecm template'. - The ecm template is a backup of the vehicle-specific settings that you can only get from the dealership/OEM. That way you have your own personal back-up of them if the ecm ever needs replacing again.
