    I would start by load testing batteries and see if any of them are bad. That would be the first place to start.

    Okay, its saying nox sensors, checking batteries 1st is a good idea. That code went away by itself after a week, now showing p200200 which I am told relates to dpf needs cleaning. Temporary lockout says "CHECK" and soot level is just to the left of "A 23 4" so I think thats good

    Did a computer diagnostic. Came up as low dpf filter efficiency. Ratio between intake/outtake nox sensors was about 50% (i.e. ppm of outtake valve was around 120ppm, and intake was 50ppm). Ideally it should be about 70% ratio or above so 120ppm outtake and 30ppm or less intake. Was told probably need dpf cleaned (baked) and may need to replace filter which is about $3000. Conversely you could do a dpf delete for a similar price and not have to mess with nox sensors, egr valves, coolers, scr, dpf filter etc. Probably will end up going that route, so looking for someone to do a quality delete not a hack job. I think I may know someone
