1. 1

   Check the electrical connector at the cylinder #3 injector solenoid valve for defective, loose, or corroded pins.

2. 2

   Inspect the wiring harness running between the Engine ECU and injector #3 for chafing, breaks, or an open circuit.

3. 3

   Test the injector solenoid by measuring resistance with a multimeter or by performing an automated 'Run-Up test' using the AGCO SISU POWER EEM4 Service Tool via a PC.

1. 1

   Preparation

   Disconnect the battery. Thoroughly clean the area around injector #3 to prevent dirt from entering the engine block or fuel system.

2. 2

   Disconnection

   Disconnect the electrical harness from the injector.

3. 3

   Marking

   Before removing the injector, mark the position of the high-pressure connection tube with an industrial marker. Assembling it in a different position can result in micro-leaks.

4. 4

   Removal

   Remove the high-pressure fuel lines and the injector hold-down clamp, then extract the faulty injector.

5. 5

   Installation

   Install the new injector and connection tube. Torque the hold-down clamp and fuel lines to factory specifications.

6. 6

   Reconnection

   Reconnect the electrical harness and battery.

7. 7

   ECU Calibration

   Connect the AGCO Service Tool to the tractor. You must program the new injector's calibration code (IQA code) into the EEM4 ECU to prevent a secondary fault code (E653.13).

8. 8

   Testing

   Bleed the fuel system and test run the engine to ensure the code is cleared and there are no leaks.
