CAUTION / NOTICE / HINT

Note

When replacing the ECM, the ECM needs Registration and Initialization Click here.

Tech Tips


  • When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.

  • Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

PROCEDURE


  1. PERFORM ACTIVE TEST USING GTS (ACTUATOR TEST OF THROTTLE VALVE)


    1. Connect the GTS to the DLC3.

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

    3. Enter the following menus: Powertrain / Engine and ECT / Active Test / Actuator Test of Throttle Valve / Data List / Throttle Valve Actuator Position.

    4. Perform the following steps 1 to 4.

    5. Step 1


      1. Perform Active Test of throttle valve with control value of 5% (opening ratio in %).

      2. Monitor the difference of the control value and Throttle Valve Actuator Position value (0 +/-3%). Throttle valve must operate within 1 second.

    6. Step 2


      1. Wait for 2 seconds or more.

    7. Step 3


      1. Perform Active Test of throttle valve with control value of 91% (opening ratio in %).

      2. Monitor the difference of the control value and Throttle Valve Actuator Position value (0 +/-3%). Throttle valve must operate within 1 second.

    8. Step 4


      1. Wait for 2 seconds or more.

    9. Perform the above steps 1 to 4 and check that the part operates as specified.

      OK
      Part operates as specified.

  2. PERFORM ACTIVE TEST USING GTS (ACTUATOR TEST OF SWIRL FLAP)


    1. Connect the GTS to the DLC3.

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

    3. Start the engine.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Actuator Test of Swirl Flap / Data List / Swirl Valve Actuator Position.

      OK
      The value of "Swirl Valve Actuator Position" changes according to the amount "Actuator Test of Swirl Flap" is operated, and the swirl flap operates smoothly.

    NG

    OK

  3. PERFORM ACTIVE TEST USING GTS (ACTUATOR TEST OF TURBO CHARGER)


    1. Connect the GTS to the DLC3.

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

    3. Start the engine.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Actuator Test of Turbo Charger.

    5. Set the control value to 5%. The variable nozzle vane turbocharger must operate within 1 second. Valve travel when adjusted is approximately 15 mm.

    6. Wait for 2 seconds and set the control value to 95%. The variable nozzle vane turbocharger must operate within 1 second. Valve travel when adjusted is approximately 15 mm.

    7. Wait for 2 seconds and stop the operation using the variable nozzle vane turbocharger Active Test.

      OK
      Operates smoothly when above procedure is performed.

      Tech Tips

      Check the movement of the variable turbine (stiffness, interference with other parts, etc.).

  4. READ VALUE USING GTS (EXHAUST TEMPERATURE B1S1)


    1. Connect the GTS to the DLC3.

    2. Start the engine and warm it up.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Exhaust Temperature B1S1.

    5. Read the value.

      Standard
      Same as the actual exhaust gas temperature (50 to 700°C [122 to 1292°F] during idling after warm-up).
      Result
      Result Proceed to
      800°C (1472°F) A
      Same as the actual exhaust gas temperature (50 to 700°C [122 to 1292°F] during idling after warm-up) B

      Tech Tips


      • If there is an open circuit, the GTS indicates -40°C (-40°F).

      • If there is a short circuit, the GTS indicates 800°C (1472°F).

  5. READ VALUE USING GTS (CHECK FOR SHORT IN WIRE HARNESS)


    1. Disconnect the exhaust gas temperature sensor (for sensor 1) connector.

    2. Connect the GTS to the DLC3.

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

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Exhaust Temperature B1S1.

    5. Read the value.
