Massey Ferguson E 9230 (31) – Engine ECU (EEM3 or EEM4): Engine specification mismatch

The system has detected a discrepancy between the engine specifications and the expected configuration. Specifically, the configuration data stored in the Engine Control Unit (ECU) does not match the data in the separate Diagnostic ID module (IDM). This mismatch can affect the proper operation of the machine and could lead to performance issues or system malfunctions.

• Massey Ferguson 8600 Series (e.g.
• 8650
• 8690)
• Massey Ferguson 7700 Series (e.g.
• 7720
• 7722)
• Massey Ferguson 8700 Series (e.g.
• 8740)

1. 1

   Verify if the Engine ECU was recently replaced or swapped from a donor tractor (a used EEM3/EEM4 block cannot be swapped without a software flash).

2. 2

   Check for accompanying codes (E 9231, E 9233, E 9235) that might indicate a hardware failure of the ID module rather than a software mismatch.

3. 3

   Inspect the physical wiring harness connection to the Diagnostic ID module for damage or corrosion.

1. 1

   Connect diagnostic tool

   Scenario A (The ECU was replaced/swapped): Connect the AGCO Electronic Diagnostic Tool (EDT) or WinEEM3/WinEEM4 service tool to the tractor's diagnostic port.

2. 2

   Update controller software

   Update the controller with the correct software matching the engine's physical data plate.

3. 3

   Request activation code

   Request an ECU activation code from AGCO SISU POWER.

4. 4

   Input activation code

   Input the activation code via the diagnostic tool to pair the ECU with the ID module. The fault code will remain active until this activation is completed.

5. 5

   Order new ID module

   Scenario B (The ID Module has failed and needs replacement): Order a new ID module from AGCO/Sisu parts, providing the exact engine serial number.

6. 6

   Connect service tool

   Connect the WinEEM3/WinEEM4 service tool to the engine.

7. 7

   Disconnect faulty module

   Disconnect the faulty ID module.

8. 8

   Request ByPass code

   Contact the Sisu Diesel Help Desk to request a 32-character 'ByPass code'.

9. 9

   Enter ByPass code

   In the service tool, click 'ByPass restrictions' and enter the code to allow the engine to communicate and run while the new module is configured.

10. 10

    Install and pair new module

    Install the new ID module and follow the EDT prompts to finalize the pairing.
