    Default 0549 code

    I downloaded the beta software, I have access to a lot of the 850,870 and 871s. everytime I try to hook up to them I keep getting this error code. I even tried doing it by a standalone bench harness, which works fine the harrness haw it should. Now I even get the message hooking up to trucks ive already read and hooked up to before, Any ideas or fixes?

    That error usually comes up when the software cannot communicate at all with the ECM. Did you manually select the ECM type or did the Auto-Detect work?

    Yeah ok so the ECM's and comms are certainly all ok.
    As the poster above you said, did you update the firmware in the V2 as well?

    We have a new beta coming out shortly that has some improvements for these older ECM's (CM850 being one of them) where Cummins were transitioning between communications protocols.

    Cheers,
