Ignition ON.
Verify there are no DTCs set related to the following component/system:
- B17 Barometric Pressure Sensor
- B75C Multifunction Intake Air Sensor
- B131 Exhaust Temperature Sensor
- B154 Diesel Particulate Filter Exhaust Differential Pressure Sensor
- If a related DTC is set
  Refer to Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis.
- Go to next step: If a related DTC is not set
Ignition ON, verify that the diesel particulate filter (DPF) Differential Pressure parameter is between 0 to +1 kPa (0 to +0.14 PSI).
- If not within the specified range
  Refer to Circuit/System Testing.
- Go to next step: If within the specified range
Engine running, verify that the DPF Differential Pressure parameter is greater than 0 kPa (0 PSI).
- If not greater than 0 kPa (0 PSI)
  Refer to Circuit/System Testing.
- Go to next step: If greater than 0 kPa (0 PSI)
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed in the Freeze Frame/Failure Records data.
Verify the DTC is not set.
- If the DTC is set
  Refer to Circuit/System Testing.
- Go to next step: If no DTC is set
