I am getting two inactive codes right after I crank the engine. I can clear them and the next time I start the bus they come back as inactive. I have an 08' IC FE with a Maxxforce DT motor. The codes I'm getting are SPN 8029, which comes up as "Undocumented Fault" and a SPN 8330 "ECM not receiving body controller CAN message" Anyone run into this problem? Bus starts and runs without problems for me, although the driver does complain that sometimes it won't start in the morning.

Try unplugging all of you J1939 connectors and plug them back in.

That kept the code from coming back, thanks. Now I just have to talk with the driver about this other issue.
