Massey Ferguson E 9233 (31) – Engine ECU: Diagnostic ID module. ID module not present.

The diagnostic ID module is not being detected by the engine's control system. This module stores essential engine data and verifies that the correct software is being used by the Engine Control Unit (ECU). Its absence prevents proper identification and communication, which can lead to restricted engine power and may limit engine speed to 1500 rpm.

1. 1

   Verify the voltage supply to the ID module, as low voltage or brownout conditions can cause the IDM to drop off the network.

2. 2

   Inspect the CAN cabling between the Engine ECU and the ID Module for breaks, chafing, or shorts.

3. 3

   Check the connector from the ECU to the IDM for insufficient contact, moisture, or corrosion.

1. 1

   Perform temporary bypass (Limp Mode)

   If you need to move the tractor immediately, disconnect the connector from the ECU to the IDM. This forces the 'ID module not present' state and automatically activates an unlimited 1-hour operation time. The engine will run for 1 hour per restart (ignition key off and restart resets the timer). This can be done up to 400 times per ID module.

2. 2

   Order replacement ID module

   Order a new ID module from AGCO/Sisu spare parts. You must provide the exact engine serial number when ordering.

3. 3

   Request ByPass code

   Request a 32-character ByPass code from the Sisu Diesel Help Desk.

4. 4

   Connect service tool

   Connect the WinEEM3 service tool to the engine diagnostic port.

5. 5

   Authorize the new module

   Leave the ID module disconnected. In the WinEEM3 software, click 'ByPass restrictions' and input the 32-character code to authorize the new module.
