John Deere 3719.16 – ECU: Calculated Soot Level Moderately High / Exhaust Filter restricted

The Diesel Particulate Filter (DPF) has accumulated a moderately high level of soot, and the engine control system has likely limited engine power (derate) to prevent damage. A parked filter cleaning (regeneration) is required immediately.

1. 1

   Check for related active codes that might inhibit regeneration, such as EGR valve faults, throttle signal issues, or DPF differential pressure sensor mismatches (e.g., ECU 003251.07)

2. 2

   Verify engine coolant temperature is above 60°C (140°F) to ensure a parked regeneration can initiate

3. 3

   Check fuel level to ensure the machine has adequate fuel for the regeneration process

4. 4

   Inspect the DPF Differential Pressure Sensor, as a failing sensor can falsely report high soot loads or cause regenerations to fail

1. 1

   Prepare the Machine

   Move the equipment to a safe, well-ventilated location away from combustible materials, as exhaust temperatures will become extremely high.

2. 2

   Meet Regeneration Criteria

   Ensure the engine is running at low idle, the coolant temperature is above 60°C (140°F), the park brake is engaged, and the PTO is turned off.

3. 3

   Initiate Parked Regeneration

   Navigate to the TechControl or CommandCenter DPF status screen. Press and hold the button under the blinking parked regeneration icon for 5 seconds to start the process. Do not use any other machine functions during this time.

4. 4

   Service Advisor Intervention

   If the parked regeneration fails (e.g., engine shuts down due to ECU protection or filter is too restricted), a qualified technician must connect the John Deere Service Advisor tool to clear latched DTCs and command a 'DPF Service Recovery' followed by a 'Service Regeneration'.

5. 5

   Component Replacement

   If the Service Regeneration fails or the soot load drops and then immediately climbs back up, replace the DPF Differential Pressure Sensor. If the DPF is physically face-plugged or has reached its maximum ash capacity, remove and professionally clean or replace it.
