Massey Ferguson E9237 – Engine Control Unit (ECU): Diagnostic ID module. ID module, monitoring reset

The Engine Identification Module (ID module) has experienced a monitoring reset or internal malfunction, causing the ECU to limit engine power and speed.

• Massey Ferguson 8600 Series (MF 8670, MF 8690)
• Massey Ferguson 7600 Series
• Massey Ferguson 6400 Series (MF 6499)

1. 1

   Check for accompanying codes (such as E9235 or E9238) to determine if the issue is a power supply problem rather than a dead module.

2. 2

   Inspect the wiring harness, pigtail, and connector for the X188 ID module for chafing, corrosion, or loose pins.

3. 3

   Verify the ECU is sending the correct reference voltage (typically 5Vdc) to the module.

1. 1

   Locate the Module

   Find the ID module bolted to the engine block near the main Engine Control Unit.

2. 2

   Remove the Faulty Module

   Disconnect the module from the engine wiring harness and unbolt it from the block.

3. 3

   Order a Serial-Specific Replacement

   Order the new ID module using the exact engine serial number so that it is programmed with the correct engine specifications and fuel mapping.

4. 4

   Install the New Module

   Bolt the new ID module securely to the engine block and plug it into the harness.

5. 5

   Clear Codes

   Turn the key on and use the tractor terminal (or AGCO EDT service tool) to clear the E9237 fault code.

6. 6

   Emergency Bypass

   If the tractor is stranded in the field, AGCO service tools can activate a 'Manual IDM bypass' state to temporarily restore engine power without the module.
