    Was sent a bigroad eld to plug into my ecm port. Connected got some strange fluctuations with my gauges, now truck wont start. Had a mechanic come out and hook up to computer, all these codes wont clear. Any ideas? Is my ecm cooked? 2015 Cascadia DD13. Any help greatly appreciated.

    Did you unplug the ELD and try to start the truck? I've seen some devices spam up the datalink when plugged in but the truck works fine once its disconnected.

    Yes. i unplugged it, and still wont start. Checked all fuses. Turned main power off for over 30 minutes. Still wont start. Interesting the fuel gauge stays in its place when truck is turned off. But the gauge is alive and cycles from E to F when you turn in “on” position?
    Any tricks to try?

    All the codes relate to J1939 messaging. Specifically timeout/missing (FMI 9 per SAE). Are you having similar fluctuations/dropouts on dash? I'd be checking the backbone and unplugging anything "extra" on the network to test. A lot of those are between ECM/TCM so it could be ECM issue related...

    Kinda late, but this ended up being a shot TCM. Transmission control module.
