    I have a CASCADIA 2013 DD13 engine. DEF system deleted by prior owner. I notice the truck is not pulling up small hills very well when empty and it’s worse when loaded.
    Diagnostic codes are
    Radar 042 SPN086566 12,
    Engine 000 SPN000639 J1939 Network 07.
    Has anyone had this issue? How do I correct it?
    Thanks in advance for any advice or insight.
