New Holland ENG 3760 – Engine Control Unit (ECU) / EDC (Electronic Diesel Control): EDC - Level 2 Monitoring: Diagnosis air path limitation due to a functional control unit monitoring forced by ECU monitoring level 2.
Issue description
Internal monitoring error within the engine's electronic control system. The controller's "Level 2" safety monitoring has detected an anomaly or limitation in the air path logic, forcing the ECU to flag a functional control unit error.

Check the cause
Verify if the fault is active and persists after a standard key-cycle and code-clearing procedure.
Connect the CNH Electronic Service Tool (EST) to the machine's diagnostic port.
Check for any available software updates or service bulletins related to the engine dataset for your specific machine.
Repair steps
Reload the Engine Dataset
Using the CNH EST, re-flash/reload the engine dataset onto the existing Engine Controller.
Re-test
Run the machine to see if the Level 2 Monitoring fault persists.
Replace the ECU
If the fault persists after the software reload, the Engine Controller (EDC) has suffered an internal failure and must be replaced.
Restore Parameters
If the EDC is replaced, you must follow the appropriate service tool procedure via the CNH EST to restore the engine's Self-Learning Parameters to the new module.
