1. 1

   Verify Recent Repairs: Determine if Injector #3 or the Engine ECU was recently replaced without programming the new injector's trim code into the ECU.

2. 2

   Read the Injector Code: Locate Injector #3 on the engine block. Read and write down the alphanumeric calibration/trim code printed or engraved on the top of the injector head.

3. 3

   Scan Tool Verification: Connect a compatible diagnostic scan tool to the tractor, navigate to the Engine ECU's injector coding section, and compare the code programmed for Cylinder 3 against the physical code you wrote down.

4. 4

   Check for ECU Updates: If the code matches but the fault persists, check if there is a software update available for the Engine ECU to resolve memory corruption issues.

1. 1

   Connect diagnostic scan tool

   Connect your diagnostic scan tool to the tractor's diagnostic port.

2. 2

   Turn ignition ON

   Turn the ignition key to the ON position (engine off).

3. 3

   Access Engine ECU

   Access the Engine ECU module and navigate to the 'Calibration,' 'Injector Coding,' or 'IQA Configuration' menu.

4. 4

   Input trim code

   Select Cylinder #3 and input the exact alphanumeric trim code printed on the injector.

5. 5

   Save configuration

   Save the configuration to the ECU.

6. 6

   Power down ECU

   Turn the ignition off for at least 30 seconds to allow the ECU to power down and save the memory.

7. 7

   Verify repair

   Turn the ignition back on, clear the fault codes, and start the engine to verify the code does not return and the engine runs smoothly.

8. 8

   Replace injector if failed

   If Injector #3 has failed mechanically or electrically, replace the injector, torque the hold-down clamp to the service manual specification, bleed the fuel system, and then perform the coding procedure above using the trim code from the NEW injector.
