    Default P10D1 code- L5P DMax

    Just a heads up for those of you who have gotten the new L5P DMax with your 2017 P/U. I started getting code P10D1 and was experiencing constant Regens- as soon as one Regen would end, another would begin shortly after shutting down and later restarting my truck. The code would appear in my Edge diag monitor and without any intervention from me, would disappear on its own. No check engine indicator came on.

    Dealership tech said that this code applied to numerous possible faults- including the DEF system. GM has new calibration s/w for both the PCM and TCM. I had my truck reflashed- so far; it isn't going into continuous Regens (again, "so far".....)
