New Holland ENG 3757 – EDC: EDC - Level 2 Monitoring: Diagnosis fault check to report the error to demand for an ICO due to an error in the PoI2 shut-off.

This code indicates an internal failure within the engine controller. Specifically, the Level 2 monitoring system has detected a failure in the shut-off path for Post Injection 2 (PoI2). Because the controller cannot verify that the post-injection circuit is shutting off correctly, it triggers this fault to demand an ICO (Injection Cut-Off) for safety and emissions compliance.

1. 1

   Connect the New Holland Electronic Service Tool (EST).

2. 2

   Read and record all active and stored fault codes.

3. 3

   Attempt to clear the fault code to see if it is an intermittent software glitch.

4. 4

   Check for any available software updates or service bulletins for the Engine Controller.

1. 1

   Reload the Engine Dataset

   Using the OEM service tool, reflash/reload the engine dataset software onto the current Engine Controller.

2. 2

   Verify

   Cycle the key and run the machine to see if the fault persists.

3. 3

   Replace the Controller

   If the fault code returns after the software reload, the internal hardware of the EDC has failed and the Engine Controller must be replaced.

4. 4

   Restore Parameters

   If the EDC is replaced, you must follow the appropriate service tool procedure to restore the engine's self-learning parameters (such as Zero Fuel Calibration and injector trim codes) to the new module.
