1. 1

   Verify recent service: Determine if the fuel injector in cylinder #2 was recently replaced but not programmed into the ECU.

2. 2

   Inspect the injector: Locate cylinder #2 and inspect the physical electronic fuel injector. Record the part number, serial number, and the calibration/trim code (often a 30-digit code or a QR code) from the identification tag.

3. 3

   Scan tool verification: Connect a compatible diagnostic scan tool to view the current calibration code stored in the ECU for cylinder #2. Compare the ECU's stored code against the physical code written on the injector.

1. 1

   Connect Diagnostic Tool

   Connect John Deere Service ADVISOR (or a compatible aftermarket tool like TEXA or Jaltest) to the machine's diagnostic port.

2. 2

   Navigate to Calibrations

   Go to the 'Tests and Calibrations' tab and select 'Injector Calibration'.

3. 3

   Enter the Trim Code

   Select cylinder #2 and click the 'Change Information' tab. Manually input the correct injector part number, serial number, and calibration trim code exactly as it appears on the physical injector.

4. 4

   Save and Verify

   Save the new calibration data to the ECU. Clear the 000652.02 fault code.

5. 5

   Test Run

   Cycle the key, start the engine, and verify that the code does not return and the engine runs smoothly.

6. 6

   Injector Replacement (If Necessary)

   If the code cannot be cleared because the injector itself has failed internally or the identification tag is illegible/damaged, the injector must be replaced. Remove the old injector, install the new one following OEM torque and cleanliness specifications, and then perform steps 1-4 to program the new injector's trim code into the ECU.
