    Default LML EGR issue

    I'm working on deleting 2013 lml. I removed dpf and installed new pipe section. Got all that working and made a couple test runs. When I park, before turning truck off there is no MIL light. When I restart I get a MIL light P140F and P1407. I looked those up they are EGR related. I havent messed with EGR yet. I'm wondering why it keeps coming up.

    P1407=EGR motor control shorted
    p140f=EGR motor current performance

    Any ideas?

    I haven't figured this one out. I blocked EGR and i still get those two. Can i just disable those two DTC reporting. I tried disabling those two and truck continues to operate ok without the MIL on. Should i leave it like that?

    How did you block the code? I think I have all the 2013 LML files and do not see any codes that can be blocked in the Engine Diagnostics section
