2020 Jeep Wrangler EcoDiesel

​

JScan displays a value called "Percentage of Soot Mass" during the DPF regeneration service procedure. Banks iDash also displays DPF SL (DPF Soot Load %).

I'm trying to identify the actual PCM data source behind that value:

- UDS / Mode 22 PID

- CAN ID / Header

- Parameter name

- Formula/scaling, if known

I am NOT looking for monitor recommendations (Banks iDash, ScanGauge, Edge CTS, etc.). I already have OBDLink CX+, OBDLink app, & Torque Pro.

I'm specifically trying to determine what parameter the PCM is exposing so I can recreate the soot load display in OBDLink/Torque Pro.

Has anyone identified the actual PID or captured it from CAN logs?

Thanks.
