Case IH 3376 – Engine Controller: Engine Controller Software Does Not Support Power Management

This code indicates a software configuration mismatch between the tractor's main vehicle control systems and the engine. The tractor's Vehicle Control Module (VCM) or armrest/cab controller has the Engine Power Management (EPM) feature enabled, but the software payload currently flashed onto the Engine Controller does not support this feature.

• Case IH Magnum Series (e.g., 235 – 340 Series 4)
• Case IH Steiger Series
• Case IH Puma Series

1. 1

   Verify if the specific tractor was factory-equipped or legitimately upgraded to utilize Engine Power Management (EPM).

2. 2

   Check recent service history to determine if the Engine Controller (ECM) or Vehicle Control Module (VCM) was recently replaced, updated, or reflashed with an incorrect software payload.

3. 3

   Connect the CNH Electronic Service Tool (EST) to read the current software versions on both the Engine Controller and the VCM.

1. 1

   Connect EST

   Connect the EST to the tractor's diagnostic port.

2. 2

   Navigate to settings

   Navigate to the vehicle configuration and instrumentation settings.

3. 3

   Disable EPM if not equipped

   If the tractor is NOT supposed to have EPM: Locate the Engine Power Management option in the configuration menu and disable it.

4. 4

   Reflash Engine Controller if EPM equipped

   If the tractor IS supposed to have EPM: You must update the Engine Controller. Navigate to the programming/flashing menu in the EST and reflash the Engine Controller (ECM) with the correct software payload that explicitly supports Power Management.

5. 5

   Cycle key switch

   Cycle the key switch to allow the modules to reboot and communicate.

6. 6

   Clear fault code

   Use the EST (or a compatible DTC eraser) to clear the inactive 3376 fault code from the Engine ECU.

7. 7

   Verify repair

   Run the tractor and verify that the code does not return and that EPM engages properly under load.
