DD15 DOC face plug cleaning procedure. Fault code 3251 FMI 0 & 2 DPF pressure out of range High

Using the Detroit Diesel Diagnostic Link Software to perform the 4.5 to 5 HOUR, yes I said HOUR. DOC face plug cleaning procedure. After doing the necessary checks, this procedure should help clear the DOC and DPF pressure fault codes provided there is NO internal damage to the One Box. If this procedure is successful then it will be completed within the 4.5 to 5 hours.

Your page will blow up. !

Ur one of the only ones on YouTube with these kind of short quick informative videos
Great style. U Cut out the Parts we don’t need.

I seen some other guys with great videos but they just press record and let it run through the whole repair.

So I’d like to suggest looking into the cause of the doc to be plugged. For example, egr cooler, possibly oil consumption as a result of blow by or turbo, bad injector causing to much soot. Love your videos. Keep posting.

Great videos u r a great resource so I have a question i have a 2015 freightliner sd114 with a DD13 it has 700k i just replaced the the dpf because it melted it was the original dpf i had the doc cleaned 1.1 lb of soot removed egr cooler removed soaked in a egr cleaning solution for 24hrs hot pipe and cold pipes delta sensor cleaned sensor replaced, all of the sensors nox, temp, doc/dpf pressure sensors replaced because when i ran the truck i got dtc 3251 fmi 21 both sensors not plausible???? there r no leaks in the system, there no kinks bends blockage in the pressure tubes because they r new i inspected the filter sensor bungs for blockage they r clear the wiring is good plugs on acm good no corrosion no bent pins no pushed back wires plugs on sensor clean tight in good condition scr voltage shows koeo voltages at 0.46/0.50 manual says thats in spec . So i clear the fault code and i figure maybe the computer needs time to relearn so i drive 50 miles and check engine light turns on, check the lap top 3251fmi21 i can clear the fault there is no derate i continue to drive 50 more mile and the code is back ! Lastly i performed the pressure sensor verification test by running a regen and it past! So what did i miss any suggestion will be greatly appreciated thanks steve.

Is there a good way to get the Detroit software without having to pay the couple grand? Also my rpm gauge keeps bouncing around by 50 rpm +/- . Any idea what might cause that?

[kEyes]

I have a question brother how can I contact you

[muther_trucker]

I keep having to take mine to the FL dealership for the DOC and I’m lucky if I can get 1000 miles in and the damn thing does it again. What is the problem?

[markjohnson]

That’s exactly what happened to my truck, I took it to freightliner in Atlanta and they told me it was the engine harness and that it was reading!! I left and an hour later lights went off. I’m nervous and not sure who to take it to to fix, any suggestions????

[survivetothrive]

I’ve got the SPN 3251 code but my FMI is 21. Only light currently is the MIL light. No engine or “stop” light yet. I can’t seem to find what it could be with that FMI. Any idea?

I appreciate it

[jbrservices]

The permanent code, you have to clear it or it will clear when you drive the vehicle?

[transport]

Truck doing to many regen when driving. Any tips what wrong?
