Thanks Alastair I will check those parameters and change my source address to match.

So I was away for two weeks and back at this situation and now I am wondering if I am trying to connect to the incorrect data ports on the cummins ECM. I am connected to the "data link" port and when I start can king I hardly see any data on the stream. I see the IDs and data in the attached picture. I am still having trouble deciphering can id to PGN but I found an online converter and 201326626 converts to 12800 which is not on the list I have for cummins.

I am no expert on CAN and J1939 but I not sure any of those are coming form the engine as they do not break down to J1939 formatting. I notice the service tool in the background, is it online and logging? If so then the messages you are seeing could be the service tool communicating with the Plus+1.


If you add the Simple J1939 identifier interpreter in CANKing it may he easier as it separates the information out into Priority, PGN, Transmission Address and Destination Address. The values are in Hex but I find it easier to convert the Hex values with Windows calculator set to programmer mode.


Don't know about the connections to the ECM as I was connected to a body builder module on the chassis that relays the CAN messages from all the nodes for the various systems.


The attached spreadsheet is an example of the messages I see from the Cummings ECM (Source address 0) on the Freightliner chassis.

You can easily display J1939 PGN in CANking. Here's the procedure :
- In the "Select Formatters" window, double click on "Simple J1939 identifier interpreter".
- It will be added in the "Active Formatters in Order of Execution" box.
- to make things clearer, unchek "Standard Text Format" in the "Active Formatters in Order of Execution" box

The PGN will be displayed in a HEX format in the "Output Window".

acmall thanks for  the reminder about service tool, I disabled it then the top line converts to pgn00000 with source address of 21, exactly what I had transmitting, that I thought I had disabled in my program. I was using the 61444 block and apparently this may be one issue as to why I coudn't get the ECM to hear my remote throttle control as its not transmitting 61444.

This still gives me concern as to why I don't see anything else from the Cummins ECM Data link. Back to checking the Cummins wiring diagram.

Thanks Sam for the refresher, I had just activated this right before your response.
