1. 1

   Verify that the ID module is physically present. It is located on the top-left corner of the engine cylinder block.

2. 2

   Inspect the wiring harness and connectors between the ID module and the engine ECU for loose connections, corrosion, or broken wires. If the ECU detects the ID module again, the bypass will automatically disable and save the remaining bypass time.

3. 3

   Use the SisuTronic EEM3 service tool to check how much bypass time remains. The bypass is strictly limited to a maximum of 200 cumulative engine hours.

1. 1

   Order the Part

   Order a new ID module from an AGCO/Sisu dealer. You MUST provide the exact engine serial number, as the ID module is hard-coded to the specific engine.

2. 2

   Remove the Old Module

   Locate the ID module on the top-left corner of the cylinder block. It is secured by two M8 breakaway capscrews. Remove these screws and disconnect the module.

3. 3

   Install the New Module

   Mount the new ID module to the block and plug in the wiring harness.

4. 4

   Software Coupling

   Connect a laptop with the SisuTronic WinEEM3s service tool to the tractor.

5. 5

   Sync ECU and ID Module

   Navigate to the Configurations tab and execute the 'Couple ECU and ID-module' command. This syncs the engine ECU with the new ID module.

6. 6

   Clear Fault Code

   Once the new ID module is successfully detected, the active bypass state will automatically terminate, and fault code E9241 will clear.
