  4. INPUT INJECTOR COMPENSATION CODE(S) INTO ECM

    B003KJRC02
    *a Example
    *b Injector Compensation Code

    Note


    • When an injector assembly is replaced, the new injector compensation code must be input into the ECM. When the ECM is replaced, all of the existing injector compensation codes must be input into the new ECM.

    • Injector compensation codes are unique, 30-digit, alphanumeric values printed on the head portion of each injector assembly. If an incorrect injector compensation code is input into the ECM, the engine assembly may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.

    • When an injector compensation code is input into the ECM, the pilot quantity learning values stored in the ECM are initialized. Also, DTC P062F is stored when the pilot quantity learning values are initialized.


    1. After replacing injector assembly with new one, input compensation code of the injector assembly into the ECM as follows:

      Tech Tips


      • Each injector assembly has different fuel injection characteristics. In order to optimize the fuel injections, the ECM uses the compensation codes to balance the different fuel injections between each injector assembly.

      • When only one or more injector assemblies are replaced, input the injector compensation code(s), perform pilot quantity learning, and then clear the DTCs.

      • When the ignition switch is turned to ON after replacing the ECM, DTC P062F is stored. This indicates that the injector compensation code(s) need to be registered. Manually clear the DTC upon completion of pilot quantity learning.


      1. Input the compensation code(s), which is/are imprinted on the head portion(s) of the new injector(s), into the GTS.

      2. Input the new compensation code(s) into the ECM using the GTS.

      3. Turn the GTS off and turn the ignition switch off.

      4. Wait for at least 30 seconds.

      5. Turn the ignition switch to ON and turn the GTS on.

      6. Perform pilot quantity learning.

      7. Clear the DTC P062F stored in the ECM using the GTS.


        Powertrain > Engine > Clear DTCs

        Note

        If the DTCs are cleared without performing pilot quantity learning, DTC P062F is stored the next time the ignition switch is turned to ON.

    2. Register compensation codes.

      B003K9VE06

      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON.

          Tech Tips

          Each injector compensation code is unique. The compensation code for each selected cylinder must be input into the GTS correctly.

        3. Confirm that the compensation code for the selected cylinder is correct, and then press "OK".

      12. B003L95C01
        *a Example

        Check that the compensation code displayed on the screen is correct by comparing it with the 30-digit alphanumeric value on the head portion of the injector assembly.

        Note

        If an incorrect injector compensation code is input into the ECM, the engine may rattle or engine idling may become rough. In addition, engine failure may occur and the life of the engine may be shortened.

        Tech Tips


        • If a wrong compensation code is input or read, return to the Input Value screen by pressing "Input".

        • The saving process may fail due to a problem with the wire harness or a bad connection with the DLC3. Check the wire harness and DLC3 connection. If no problem is found with either, the ECM may be malfunctioning. Check the ECM and repeat this operation.

      13. Press "Next" to register the compensation code in the ECM.

        Tech Tips


        • If the registration process fails, the compensation code may be incorrect. Check the compensation code again.

      19. Clear the DTC P062F stored in the ECM using the GTS.


        Powertrain > Engine > Clear DTCs

        Note

        If the DTCs are cleared without performing pilot quantity learning, DTC P062F is stored the next time the ignition switch is turned to ON.

  5. PILOT QUANTITY LEARNING

    Note

    Driving conditions during "Pilot Quantity Learning" using the GTS differ from normal as the EGR remains constantly ON. As a result, leaving the engine idling during "Pilot Quantity Learning" for long periods of time may damage the engine. Therefore, perform "Pilot Quantity Learning" immediately after the engine is warmed up (within approximately 20 minutes).


    • "Pilot Quantity Learning" is performed when injector assemblies have been replaced and injector compensation codes have been registered. "Pilot Quantity Learning(Detail)" is performed when there are engine problems but no DTCs are output and the technician wishes to clear the learned values and have the vehicle relearn the values.

    • This procedure uses the GTS to perform "Pilot Quantity Learning".

    • When replacing the injector assembly, engine or ECM, perform this procedure after performing injector compensation (manual ID code registration).

    B003O6PE09

    Note

    After completing this procedure, clear the DTCs using the GTS.

    Tech Tips


    • B003M3S

      If "Exit" is pressed during the step where the accelerator pedal is operated and "Pilot Quantity Learning" is canceled, turn the ignition switch off, wait 10 seconds, check the vehicle condition, and then perform learning again.

    • If an error occurs during learning, check the vehicle condition after turning the ignition switch off, and then perform learning again.

    • If learning is canceled and DTCs are output due to excessive racing of the engine (depressing the accelerator pedal for 2 seconds or more), turn the ignition switch off, and then perform learning again.

    • A communication malfunction may occur if there is a problem with the ECM, a wire harness or the connection to the DLC3. If the wire harnesses and the connection to the DLC3 are inspected and found to be normal, the ECM may be malfunctioning.

    The VIN is a 17-digit alphanumeric vehicle identification number. The GTS is required to register the VIN.

    This registration section consists of two parts, Read VIN and Write VIN.


    1. Read VIN: Explains the VIN reading process in a flowchart. This process allows the VIN stored in the ECM to be read, in order to confirm that the two VINs, provided with the vehicle and stored in the vehicle's ECM, are the same.

    2. Write VIN: Explains the VIN writing process in a flowchart. This process allows the VIN to be input into the ECM. If the ECM is changed, or the ECM VIN and vehicle VIN do not match, the VIN can be registered, or overwritten in the ECM by following this procedure.
