John Deere 003719.15 – EIC: DPF Soot Load Is High (ECU)

The Engine Control Unit (ECU) has determined the soot load in the DPF is above the normal operating range, at its least severe level. This fault is logged by the Engine Interface Control Unit (EIC) and triggers a 'Diesel Particulate Filter Regeneration Fault' or 'Calculated Soot Level Slightly High' message. If this condition is not addressed, it can lead to further restrictions, loss of engine power, and may prevent automatic or active regeneration cycles from occurring.

1. 1

   Attempt an operator-level 'parked' or 'stationary' regeneration via the machine's display (requires parking brake engaged, PTO disengaged, and engine idle above 1000-1200 RPM).

2. 2

   Inspect the entire exhaust system for any leaks or physical damage that could affect pressure and temperature readings.

3. 3

   Check engine operating conditions to ensure the machine is being operated at a sufficient load to allow for passive regeneration, as consistently low-load cycles contribute to soot buildup.

4. 4

   Inspect the DPF pressure sensors and exhaust temperature sensors for damaged wiring or loose connections, which can provide incorrect data to the ECU and prevent proper regeneration.

1. 1

   Attempt parked regeneration

   Follow the instructions in the operator's manual to perform a parked regeneration. This process burns off the accumulated soot.

2. 2

   Perform service regeneration

   If a standard parked regeneration is unavailable or fails, a 'service regeneration' may be necessary. This often requires a diagnostic tool like John Deere Service ADVISOR™ to initiate.

3. 3

   Diagnose and replace faulty sensors

   If regeneration cycles fail to start or complete, and the soot load continues to climb or gives abnormal readings during the process, the DPF differential pressure sensor is a likely culprit. A known failure pattern involves the differential pressure reading decreasing in the first half of a service regeneration and then beginning to climb again. Replace the sensor if found to be faulty.

4. 4

   Post-replacement regeneration

   After replacing a faulty sensor, perform another service regeneration to clear the fault codes and reset the soot load parameters in the ECU.

5. 5

   Perform DPF ash service

   If the machine has high hours (typically 3,000-4,500 hours), the DPF may be full of non-combustible ash that cannot be burned off through regeneration. Remove the DPF and have it professionally cleaned by a qualified service provider using specialized equipment.

6. 6

   Replace DPF assembly

   If the DPF is damaged or cannot be effectively cleaned, it must be replaced.
