CYLINDER HEAD GASKET (w/ DPF) REMOVAL

CAUTION:

When replacing an injector (including interchanging injectors between cylinders), common rail, cylinder head, or intake manifold, replace the corresponding injection pipes with a new one.

Note

When fuel lines are disconnected, air may enter the fuel lines, leading to engine starting trouble. Therefore, perform forced regeneration and bleed the air from the fuel lines.


  1. PRECAUTION

    Note

    After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work Click here.

  2. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

    Note

    When disconnecting the cable some systems need to be initialized after the cable is reconnected Click here.

  3. REMOVE NO. 1 TURBOCHARGER SUB-ASSEMBLY WITH EXHAUST MANIFOLD RH AND NO. 2 TURBOCHARGER SUB-ASSEMBLY WITH EXHAUST MANIFOLD LH

  4. CHECK INJECTOR COMPENSATION CODE

    A0159NUE05

    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.

    Text in Illustration
    *1 Injector Compensation Code
    *a Example

    1. After replacing injector assemblies with new one(s), input injector compensation code(s) of the injector assemblies 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 engine switch is turned on (IG) 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 assemblies, into the GTS.

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

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

      4. Wait for at least 30 seconds.

      5. Turn the engine switch on (IG) and turn the GTS on.

      6. Perform pilot quantity learning.

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

        Note

        If the DTCs are cleared without performing pilot quantity learning, DTC P062F is stored immediately after clearing DTCs.

    2. Register compensation codes.

      A015AIOE04

      1. Connect the GTS to the DLC3.

      2. Turn the engine switch on (IG).

        Note

        Do not start the engine.

      3. Turn the GTS on.

      4. A015BL1

        Enter the following menus: Engine and ECT / Utility / Injector Compensation.

      5. Press Next.

      6. A015BOM

      8. Press Next.

      9. A0159FQ

        Select the number of the cylinder corresponding to the injector compensation code that you want to register.

      10. Press Next.

      11. A015CV0

        Register compensation code.


        1. Press Input.

        2. A0158O4

          Manually input the cylinder compensation code using the keyboard on the GTS screen. The code is a 30-digit, alphanumeric value printed on the injector head portion.

          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. A015C7A

        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 injector compensation code in the ECM.

        Tech Tips


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

        • If the input injector compensation code fails to register even though it is input correctly, there may be 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 restart this operation.

      14. A0158CJ

        If you want to continue with other compensation code registrations, press Next. To finish the registration, press Exit.

      15. Turn the GTS off and turn the engine switch off.

      16. Wait for at least 30 seconds.

      17. Turn the engine switch on (IG), and then turn the GTS on.

      18. Perform pilot quantity learning.

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

        Note

        If the DTCs are cleared without performing pilot quantity learning, DTC P062F is stored immediately after clearing DTCs.
