Case IH 3755 – Engine Controller: Level 2 Monitoring error

Triggered by a diagnostic fault check reporting an error due to a torque comparison mismatch or a plausibility check on fuel pressure (often monitoring for a sticking sensor). The system detects that the engine's operating parameters are out of sync with the expected dataset, prompting a mandatory software reload or hardware replacement.

1. 1

   Inspect the fuel pressure sensors for sticking or erratic readings (plausibility check)

2. 2

   Ensure there are no loose connections or voltage drops to the EDC that could cause a torque comparison error

3. 3

   Verify if the machine has the latest software update

1. 1

   Connect diagnostic tool

   Connect the Case IH Electronic Service Tool (EST) to the machine's diagnostic port.

2. 2

   Reload Engine Dataset

   Using the EST, Reload the Engine Dataset (reflash the engine controller with the correct software parameters).

3. 3

   Clear fault codes

   Clear the fault codes and operate the machine to see if the fault persists.

4. 4

   Replace Engine Controller

   If the fault persists after the dataset reload, the Engine Controller (EDC) has suffered an internal hardware failure and must be replaced.

5. 5

   Install new Engine Controller

   Install the new Engine Controller.

6. 6

   Restore Self-Learning Parameters

   If the EDC is replaced, you MUST follow the appropriate service tool procedure in the EST to Restore Self-Learning Parameters (such as zero fuel calibration and injector coding).
