    Hey guys, i noticed on my tuck that check engine come on and off sometimes, on ELD fault codes it show :

    SPN-5397 31 Aftertreatment 1 Diesel Particulate Filter Regeneration too Frequent

    I notice few threads for this code but none with KW . It is 2017 Paccar engine.
    At the shop they told me bad reading if I started moving while truck did regen and it was parked.

    Any experiences?

    Could be a number of things. How many miles since DPF was serviced?
