Case IH 3757 – Engine Control Module (ECM) / 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 indicates an internal failure or calibration error within the engine controller regarding the "Post Injection 2" (PoI2) shut-off plausibility. The system's Level 2 monitoring has detected that the engine control unit cannot properly command or verify the shut-off of the second post-injection fuel event.

1. 1

   Connect the CNH Electronic Service Tool (EST) to the machine

2. 2

   Check for any accompanying injector short-circuit or wiring fault codes (which could theoretically cause erratic internal logic)

3. 3

   Clear the inactive codes to see if the fault is a hard, persistent failure

1. 1

   Reload the Dataset

   Using the CNH Electronic Service Tool (EST), reflash/reload the Engine Dataset (calibration file) to the EDC.

2. 2

   Evaluate

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

3. 3

   Replace the EDC

   If the fault persists after a software reflash, the Engine Controller (EDC) has suffered a hard internal failure and 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 to the new module.
