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. INSPECT EXHAUST GAS TEMPERATURE SENSOR (FOR SENSOR 2)


    1. Using the GTS, check the value of Exhaust Temperature B1S2.


      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 B1S2.


        Powertrain > Engine and ECT > Data List
        Tester Display
        Exhaust Temperature B1S2

      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).

    2. Inspect the exhaust gas temperature sensor (for sensor 2).

  2. CHECK HARNESS AND CONNECTOR (EXHAUST GAS TEMPERATURE SENSOR (FOR SENSOR 2) - ECM)


    1. Disconnect the exhaust gas temperature sensor (for sensor 2) connector.

    2. Disconnect the ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      B110-1 (THCO) - B112-109 (THCO) Always Below 1 Ω
      B110-2 (E2) - B112-110 (ETCO) Always Below 1 Ω
      B110-1 (THCO) or B112-109 (THCO) - Body ground Always 10 kΩ or higher

  6. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. Connect the GTS to the DLC3.

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

    3. Clear the DTCs.


      Powertrain > Engine and ECT > Clear DTCs

    4. Turn the ignition switch off and wait for 60 seconds or more [A].

    5. Perform road test [B].

    6. Repeat [A] and [B] for the number of trips detected.

    7. Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.


      Powertrain > Engine and ECT > Trouble Codes

    8. Confirm that the DTC is not output again.
