John Deere 000107.15 – ECU / CCU: Air Filter Obstruction

The engine's air filter is obstructed. This condition is triggered by a sensor detecting a high-pressure differential in the air intake system. The FMI 15 code signifies a least severe level warning, indicating the obstruction requires attention but may not have caused immediate critical issues. If left unaddressed, this condition can lead to reduced engine performance, increased fuel consumption, and potential engine damage.

1. 1

   Visually inspect the air filter housing and intake system for any obvious blockages, such as debris accumulation at the intake pre-cleaner.

2. 2

   Open the air filter housing and inspect both the primary and secondary air filters for heavy dirt and restriction. The primary filter will likely be visibly dirty if it is the cause.

3. 3

   Review the machine's service records to see when the air filters were last replaced (intervals can be as frequent as every 250 hours depending on conditions).

4. 4

   Inspect the air filter restriction sensor and its wiring for any signs of damage, corrosion, or loose connections. The sensor is typically located on the air filter housing or on the air intake tube leading to the engine.

1. 1

   Prepare machine for service

   Park the machine on a level surface, lower all implements to the ground, shut down the engine, and remove the key. Disconnect the battery ground strap before working on electrical components.

2. 2

   Clean or replace air filters

   Remove the cover from the air filter housing and carefully remove the primary air filter element. If heavily soiled, replace it (tapping out dust is only a temporary solution). Inspect the secondary (inner) air filter; if the primary filter failed and allowed dirt to pass, replace the secondary filter as well. Never attempt to clean the secondary filter. Wipe the inside of the housing clean with a damp cloth before installing the new filters and securing the cover.

3. 3

   Test the air filter restriction sensor

   If the filters were not significantly dirty or if replacing them does not clear the code, check the sensor's wiring and connectors. A specific diagnostic test (Reference: 245-CCU-012R, Engine Air Filter Restriction Sensor Test) may be required to verify the sensor has not failed.

4. 4

   Clear fault code

   Reconnect the battery, start the machine, and check if the fault code has cleared. On some models, the code clears automatically once the obstruction is no longer detected. If it persists, clear it using the machine's diagnostic interface.

5. 5

   Final verification

   If the code returns after filter replacement and clearing, there may be a more complex issue with the sensor circuit or the ECU, requiring diagnosis by a qualified technician.
