Exhaust filter percentage always at 0%

Hello ive been monitoring the exhaust filter percent and I haven't seen it change from zero. I pulled drove 170 miles today in all sorts of conditions and it stayed at 0 all day. I know ive seen it move before so its got me thinking. Anyone else have this problem?

Truck is '12 regular cab DRW...pulls like a champ! The 6.7 puts the 6.4 to shame (stock)

If your working it hard enough, and the EGT's are high enough, your truck does a passive regen, and burns soot without telling you. That could explain it.

You still have a DPF right?

What are you monitoring it with?

A couple of the PIDs on the Edge Insight don't work or only show values at start up. Watch the Soot % it works.

As stated, Towing where you have EGTs above 572° will perform a passive regen and you will actually see the Soot % drop.

Truck is completely stock with 4500 miles. I monitor it with the display on the speedometer. (it doesnt have the bigger lcd screen, xl package) Just hit info on the steering wheel and it cycles through.

I understand about the passive regeneration but I did idle the truck for a good half hr and the percentage never changed. In the past I have monitored the % and it jumped around quite a bit. I just dont see how it could always be at 0% unless a sensor is messed up or its always cleaning exhaust filter (my real concern)

I have the LCD screen and there is no way to monitor soot

Really? I ordered it with the OCR (operator command regeneration) option, maybe is has something to do with that? I will take a pic and show what it looks like.

that must be it because i dont have that option on my screen either. it only tells me if the fluid is ok or under half.
