1. 1

   Verify Recent Repairs: Check if Injector #2 was recently replaced. If a new injector was installed but not programmed into the ECU, this code will immediately trigger.

2. 2

   Read Current ECU Data: Connect a compatible diagnostic scan tool (such as AGCO EDT, Jaltest, or Bosch ESI[truck]) and read the injector calibration codes currently stored in the Engine ECU.

3. 3

   Visual Inspection: Locate cylinder #2 on the engine. Read the physical IQA/QR code printed on the top of the injector and compare it to the code stored in the ECU.

1. 1

   Connect Diagnostic Tool

   Plug your diagnostic scanner into the tractor's diagnostic port and establish communication with the Engine ECU.

2. 2

   Navigate to Injector Coding

   Access the "Calibrations" or "Injector Coding" menu within the engine management software.

3. 3

   Input the Correct Code

   If the code in the ECU does not match the physical injector, manually type the alphanumeric code found on the top of Injector #2 into the software.

4. 4

   Save and Flash

   Save the new configuration to the ECU.

5. 5

   Clear Codes

   Clear the 000652.13 fault code from the system.

6. 6

   Test Run

   Cycle the ignition key, start the engine, and let it idle. Verify that the fault code does not return.

7. 7

   Injector Replacement (If Necessary)

   If the code is correct but the ECU continually rejects it, or if the injector is electrically/mechanically failed, the injector must be replaced. After installing the new injector, you must perform steps 1-6 to program the new injector's unique code into the ECU.
