Post Custom PIDs stopped working
on: January 14, 2019 (GMT)

Not sure if this is related to a recent update of the app but I have had a few custom PIDs that have been working for ages stop working or are reporting differently then before?

Vehicle is a 2016 Ram 2500 Cummins. There have been no updates to the truck itself since these stopped working.

Examples:

Function- DPF Average regen distance
018b
((F*256)+G)0.621

This used to show the distance between DPF regens and now it just shows zero?

Also have one very similar PID that showed time between regen and it now shows zero. Both have been working for a long time up until recently.

Also have one for DPF Regen status. It Shows a count down in percentage of when the next regen will occur.
When it hit 100% the vehicle would initiate a regen and I would see that percentage steadily drop down to around 20% as the regen occurred.
No all the sudden when it hits 100% the regen starts but the meter (PID) jumps immediately down to around 20% and just stays there while the regen occurs. I no longer see the progress happening?

The PID on that one is
018b
BIT(B:0)

Any help would be appreciated. Like I said these have all worked fine for quite some time but recently started acting differently.

Regards.

You seem to be missing * on
the first equation. (*0.621371192
for kilometers to miles).

Note: the pid editor still shows green
check mark without * but results are
different. (Appears to concatenate the
two values 2570.621371192 when testing
offline).

The second equation is for On/Off bit 0
status – not %. A different variable and
equation is likely needed for %.

Sorry, I wrote the wrong equation for the % Status, that one was a on/off status indicator when a regen was occurring

The DPF % status is:
018B
(C*100)/255

With that said these have both been working perfectly for at least 6 months like this? That’s why I was thinking an update to the app my have caused a change?

Testing 018b and posting the raw hex
response would be helpful.

Are you using Auto for header?

Were you using a custom init string?

Is a different module responding?

The last app update did have a bug fix
for profile loading according to the
changelog.
