New Holland ENG 3753 – EDC (Electronic Diesel Control): EDC - Level 2 Monitoring: Diagnostic fault check to report the error due to injection quantity correction.

The engine's control system has detected an internal plausibility error or corruption regarding the fuel injection quantity correction parameters. This is triggered when the module's calculated correction factor exceeds allowable safety limits, or if the module's memory regarding these self-learned parameters fails a Level 2 internal watchdog check.

1. 1

   Ensure the machine's battery is fully charged and the alternator is outputting correct voltage.

2. 2

   Scan the EDC for other active fuel system codes (e.g., rail pressure deviations or injector circuit open/shorts).

3. 3

   Connect the New Holland Electronic Service Tool (EST) to verify the code is active and to prepare for software procedures.

1. 1

   Reload the Engine Dataset

   Using the New Holland EST, reflash or reload the engine calibration software (dataset) onto the existing EDC.

2. 2

   Test the Machine

   Clear the fault codes and cycle the engine to see if code 3753 returns.

3. 3

   Replace the EDC

   If the fault persists after the dataset has been successfully reloaded, the Engine Controller (EDC) has suffered an internal hardware/memory failure and must be replaced.

4. 4

   Restore Self-Learning Parameters

   If the EDC is replaced, you must follow the appropriate service tool procedure in the EST to restore the engine's self-learning parameters. This includes programming the injector IQA codes, zero fuel calibration, injection angles, and injection time into the new module.
