      Example
      *1 Fuel Injector Compensation Code

      INPUT INJECTOR COMPENSATION CODE(S) INTO ECM

      Note


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

      • Fuel injector compensation codes are unique, 30- digit, alphanumeric values printed on the head portion of each fuel injector. If an incorrect fuel 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 a fuel injector compensation code is input into the ECM, the pilot quantity learning values stored in the ECM are initialized. Also, DTC P1601 is stored when the pilot quantity learning values are initialized.


      1. After replacing fuel injector(s) with new one(s), input compensation code(s) of the fuel injector(s) into the ECM as follows:

        Tech Tips


        • Each fuel injector 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 fuel injector.

        • When only one or more fuel injectors are replaced, input the fuel 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 P1601 is stored. This indicates that the fuel 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 fuel injector(s), into the intelligent tester.

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

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

        4. Wait for at least 30 seconds.

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

        6. Perform pilot quantity learning.

        7. Clear DTC P1601 stored in the ECM using the tester.

          Note

          If the DTCs are cleared without performing pilot quantity learning, DTC P1601 is stored the next time the ignition switch is turned to ON.

      2. Register compensation codes.

        A004OERE40

        1. Connect the intelligent tester to the DLC3.

        2. Turn the ignition switch to ON.

          1. Press Input.

          2. A004Q40

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

            Tech Tips

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

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

        12. A004TT8

          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 fuel injector.

          Note

          If an incorrect fuel 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.

          • If the input 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. A004T4K

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

        15. Turn the ignition switch off, and then turn the tester off.

        16. Wait for at least 30 seconds.

        17. Turn the ignition switch to ON, and then turn the tester on.

        18. Perform pilot quantity learning.

        19. Clear DTC P1601 stored in the ECM using the tester.

          Note

          If the DTCs are cleared without performing pilot quantity learning, DTC P1601 is stored the next time the ignition switch is turned to ON.

    5. PILOT QUANTITY LEARNING


      • "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 intelligent tester to perform "Pilot Quantity Learning".

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

      A004RO3E06

      Note

      After completing this procedure, clear the DTCs using the intelligent tester.

      Tech Tips

      Example
      *1 Fuel Injector Compensation Code

      INPUT INJECTOR COMPENSATION CODE(S) INTO ECM

      Note


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

      • Fuel injector compensation codes are unique, 30- digit, alphanumeric values printed on the head portion of each fuel injector. If an incorrect fuel 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 a fuel 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 fuel injector(s) with new one(s), input compensation code(s) of the fuel injector(s) into the ECM as follows:

        Tech Tips


        • Each fuel injector 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 fuel injector.

        • When only one or more fuel injectors are replaced, input the fuel 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 fuel 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 fuel injector(s), into the intelligent tester.

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

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

        4. Wait for at least 30 seconds.

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

        6. Perform pilot quantity learning.

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

          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.

            Tech Tips

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

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

        12. A004TT8

          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 fuel injector.

          Note

          If an incorrect fuel 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.

      *1 Fuel Injector Compensation Code

      INPUT INJECTOR COMPENSATION CODE(S) INTO ECM

      Note


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

      • Fuel injector compensation codes are unique, 30- digit, alphanumeric values printed on the head portion of each fuel injector. If an incorrect fuel 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 a fuel 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 fuel injector(s) with new one(s), input compensation code(s) of the fuel injector(s) into the ECM as follows:

        Tech Tips


        • Each fuel injector 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 fuel injector.

        • When only one or more fuel injectors are replaced, input the fuel 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 fuel 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 fuel injector(s), into the intelligent tester.

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

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

        4. Wait for at least 30 seconds.

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

        6. Perform pilot quantity learning.

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

          Note

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

      Example
      *1 Fuel Injector Compensation Code

      INPUT INJECTOR COMPENSATION CODE(S) INTO ECM

      Note


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

      • Fuel injector compensation codes are unique, 30- digit, alphanumeric values printed on the head portion of each fuel injector. If an incorrect fuel 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 a fuel 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 fuel injector(s) with new one(s), input compensation code(s) of the fuel injector(s) into the ECM as follows:

        Tech Tips


        • Each fuel injector 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 fuel injector.

        • When only one or more fuel injectors are replaced, input the fuel 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 fuel 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 fuel injector(s), into the intelligent tester.

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

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

        4. Wait for at least 30 seconds.

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

        6. Perform pilot quantity learning.

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

          Note

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

      Example
      *1 Fuel Injector Compensation Code

      INPUT INJECTOR COMPENSATION CODE(S) INTO ECM

      Note


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

      • Fuel injector compensation codes are unique, 30- digit, alphanumeric values printed on the head portion of each fuel injector. If an incorrect fuel 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 a fuel injector compensation code is input into the ECM, the pilot quantity learning values stored in the ECM are initialized. Also, DTC P1601 is stored when the pilot quantity learning values are initialized.


      1. After replacing fuel injector(s) with new one(s), input compensation code(s) of the fuel injector(s) into the ECM as follows:

        Tech Tips


        • Each fuel injector 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 fuel injector.

        • When only one or more fuel injectors are replaced, input the fuel 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 P1601 is stored. This indicates that the fuel 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 fuel injector(s), into the intelligent tester.

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

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

        4. Wait for at least 30 seconds.

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

  21. REGISTRATION RELATED TO TIRE PRESSURE WARNING SYSTEM


    1. BEFORE REGISTRATION

      Note

      The transmitter ID is written on the tire pressure warning valve and transmitter. It is not possible to read the transmitter ID after installing the tire to the wheel. Therefore, make a note of the transmitter ID before installing the tire.


      1. In case of tire pressure warning ECU and receiver replacement:


        1. Read the registered transmitter IDs that are stored in the old ECU using the GTS and note them down.

        2. If reading the stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning ECU and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valve and transmitters.

      2. In case of tire pressure warning valve and transmitter replacement:


        1. Take a note of the 7 digit number (transmitter ID) written on the tire pressure warning valve and transmitter.

      Tech Tips


      • The previously registered IDs will be cleared from memory when the registration is completed.

      • If the ID registration step is not completed within 300 seconds, ID registration will be canceled.


      1. Set the air pressure of all tires to the specified value(s).

      2. Turn the ignition switch off

      3. Connect the GTS to the DLC3.

      4. Turn the ignition switch to ON and the GTS on.

      5. Enter the following menus: Chassis / Tire Pressure Monitor / Utility / ID Registration.

      6. Perform the procedure displayed on the GTS.

    3. CONFIRMATION OF TRANSMITTER ID REGISTRATION

      Note


      • It may take up to a few minutes to update the tire pressure data. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24.

      • If the IDs have not been registered, DTC C2171/71 is stored in the tire pressure warning ECU and receiver after 3 minutes or more.

      • If normal pressure values are displayed, the IDs have been registered correctly.

      • If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.

      • After all IDs are registered, DTC C2126/26 is stored in the tire pressure warning ECU and receiver and the tire pressure warning light blinks for 1 minute and then illuminates. When the tire pressure warning ECU and receiver successfully receives signals from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is cleared and the tire pressure warning light goes off.


      1. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

  22. INITIALIZATION RELATED TO TIRE PRESSURE WARNING SYSTEM

    Note


    • Initialization can be confirmed through the tire pressure warning light.

    • The order in which the data is received is random.

    • If the signals from all the wheels are received, initialization is completed.

    • Initialization is completed when the Data List "ID Tire Inflation Pressure" display shows the correct pressures.

    • Initialization is normally completed within a few minutes.

    • It may take up to a few minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2124/24.

    • If initialization has not been completed successfully, DTC C2177/77 is stored after a vehicle speed of 37 km/h (23 mph) or more continues for 20 minutes or more.

    • During test mode (sensor check mode), the system will not change to initialization mode even if the tire pressure warning reset switch is pushed.

    • Initialization can be terminated by connecting terminals 13 (TC) and 4 (CG) of the DLC3.

      Tech Tips


      • Recognition code registration is necessary when replacing the door control transmitter or the door control receiver.

      • Add mode is used to register new recognition codes while still retaining codes already registered. This mode is used when a new transmitter is added. If the number of registered codes exceeds 4, the previously registered codes will be cleared in order, starting from the first registered code.

      • Rewrite mode is used to clear all the previously registered recognition codes in order to register new recognition codes. This mode is used when the transmitter or the door control receiver is replaced with a new one.

      • Confirmation mode is used to confirm how many recognition codes have already been registered before registering any additional recognition codes.

      • Prohibition mode is used to clear all the registered codes and disables the wireless door lock function. This mode is used when the transmitter is lost.

      • All of the following registration procedures must be performed in order and in a continuous sequence.
