SUBJECT:
Residual flow (ResFlow) test for the Diesel Particulate Filter (DPF) in 2012 - 2018 Model Year DIESEL trucks
MODELS:
FEC52, FEC72, FEC92, FGB72
DESCRIPTION:
A new tool is now available within XENTRY Diagnostics to test the flow resistance in the DPF. An XENTRY
Diagnostics patch download file labeled "EEC ResFlow #2” has been posted on Fusonet under Service  Diagnostic
Tools  Hardware and Software to download the patch. A downloadable patch installation guide is located just to
the right of the patch file.

To test the DPF’s residual flow:
1. Connect XENTRY Diagnostics.
2. Click Diagnosis  EEC  Actuations.
3. Choose “013 ResFlow” under Development Data.
4. With the transmission in park, hold the engine speed at 2500 RPM for 2 minutes.
5. After 2 minutes, while at 2500 RPM, click the “S” button and record the ResFlow value.
6. Perform a full DPF regeneration.
7. After the regeneration completes, hold the engine speed at 2500 RPM for 2 additional minutes.
8. After 2 minutes, while at 2500 RPM, click the “S” button and record the ResFlow value.
A ResFlow value after DPF regeneration lower than 0.15 indicates that the DPF is within normal specifications
for residual flow.
