    Default $0502 Error when attempting BBR on CMB849

    I get this error when I try to read the 849B Cummins Controller. I have enabled Cummins 849B for BBR/BBF under the BBX tab in V8 and I've programmed my hardware. Same error on the Autocal and the V2. I'm assuming the options file is messed up somehow but I'm not exactly sure how. I've attached it to this post.

    Thanks for the help.

    Latest updates, dated June 6th/8th?

    Have you tried formatting the config of your V2 and formatting the SD card, then copying the new files over?

    Erik,

    I am on the latest software and firmware. Updated today, should've mention that. I have formatted the config as part of my troubleshooting.

    V8.2. build 156 FW- 2.07.12

    Thanks for the help,

    Hmmm, $0502 is no *.obj file found.

    Try formatting your V2 config again, then open the attached file in V8 S&T and Program your V2 with it. Might not make a difference, cant hurt to try though.

    Then open EFILive Explorer and make sure the CMB.pmm, CMB_F.obj, and CMB_R.obj are copied to your V2.
