DIST_LAST_DPF

Hi,

Does anyone have the PID details for the distance to last complete regeneration?

I’ve found
220434
((A<16)+(B<8)+C)*0.24
7E0
But doesn’t seem to work.

Or better yet, can anyone explain how to pull out the pid/equation details from Forscan (if possible)?

Thanks

PID does not exist in a Ranger.

Try

220614
(E*256 + F)*1/10

km - Distance Travelled Since Last Diesel Particulate Filter (DPF) Regeneration

Thanks for the reply Stewart. Unfortunately it's not working. The PID is "active" but just returns 0km all the time. I'll keep it running to see if it needs a regeneration to occur to start the counter.

Sorry, wrote that in a weird way but result will be the same unless something weird is going on in the software.

Cleaned and shortened. ((E*256)+F)/10

Will test on bench in next couple of days in a different way to make sure it is relevant.

Thanks Stewart
I've updated the formula but still no luck

I have Distance between regens and Time between regens but that is with the Obdlink app
Distance and time can vary quite a bit between city only driving to towing a van on a 4 week trip
Same with the burn off
DPF burns off to around 25% in the city but burns off to 10% or less while towing

Stupid mistake. It is a multi frame message and my brain was reading the data back to front.

For Torque app..........

(A * 256 + B)/10
or
((A * 256) +B)/10

Same same.

Ross, you can test this in OBDlink.
Descott, you can test this in Torque.

I do not have a DPF.

OBDlink
Name Whatever
Module: 7E0
Mode: 22
PID: 0440
Equation: A:4


Torque test.
Name Whatever
Module: 7E0
PID: 220440
Equation: {B:4}

Torque maths could also use BIT(A:4) or BIT(B:4) but will need to be tested.

Result should be 0 = DPF regen in NOT active 1 = DPF regen is active

Stewart, I tried this today but not sure I have set it up correctly in the Min & Max values
I have Min 0 and Max1
Maybe when it does a burn it will be ok

Just leave all other setting alone. Only add what I put write.

Should change to 1 on a regen.
Have tested with other snitch inputs on the bench with indicators etc. so as long as the PCM does switch this particular PID then it should change.

Thanks, I'll test it out this week. Should be doing a regen towards the end of the week based on my km expextations

The updated distance formula works a treat thanks, however the regen active does not, still returns 0 during a regen. I'll try the BIT formula next

Nothing to say it will work. Just because it is in the data that I look at for the PCM does not mean it is in the actual PCM firmware. Easier for me to test quickly on a vehicle at hand in my own time but I'm pre DPF.

Is it possible to get the following converted to Scangauge?

220614
((A * 256) +B)/10

km - Distance Travelled Since Last Diesel Particulate Filter (DPF) Regeneration

Thank you!

TXD 07E0220614

Should be right.

Thanks for the quick reply Stewart. I just input the data into the Scangauge 3 but it isn’t showing up. Are you able to double check the info? As it works in torque pro.

Thanks!

I found another version online for 3.0L and 3.2L Powerstroke. It is in miles:

TXD 07E0220A18
RXF C562860A3718
RXD 3810
MTH 001F00320000

It looked to be working so I adjusted the MTH to convert to kilometers

MTH 007C007D0000

I'll confirm once the ranger goes through a burn whether it works 100%.

This should not give correct data anyway as it would not contain all data to / 10.
220614
((A * 256) +B)/10

Data is 6 bytes and not 2 so is a multi frame message. I cannot find any relevant documentation how scangauge handles this although I know it. Suggest chasing scangauge for more a more technical explanation of RXF and RXD.

It is odd that you get any data from PID 0A18 as it is not a valid PID for that engine and although the RXF does have some multipliers in there the filter looks totally wrong.

If I get time over the weekend I will flick an email through to one of the scangauge engineers with some data as 0614 is the correct PID for this engine.

I have sent an email to engineering for clarification and expanded information on RXF and RXD.

I've got no answers for you sorry (mainly as I have a limited understanding of what I'm actually doing!), other than PID 0614 returned NoData on Scangauge 3 and PID 0A18 looks to return valid data. I'll be doing a burn in 90km (my Ranger does a burn every 600km unless soot load fills up prior to that).
