CAUTION / NOTICE / HINT

Note:

After replacing the ECM, the new ECM needs registration (Click here) and initialization (Click hereНажмите здесь).

Tip:

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. CHECK DTC OUTPUT (IN ADDITION TO DTC P011C)

    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 / Trouble Codes.

    4. Read the DTCs.

      Powertrain > Engine and ECT > Trouble Codes

      Tip:

      If any DTCs other than P011C are output, troubleshoot those DTCs first.

  2. READ VALUE USING GTS (COOLANT TEMP)

    1. Allow the engine to soak for 1 to 2 hours.

      Tip:
      • It is not necessary to allow the engine to soak if the engine is cold.

      • The engine cools faster if the hood is opened.

    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 / All Data / Coolant Temp.

      Powertrain > Engine and ECT > Data List
      Tester Display
      Coolant Temp
    5. Read the value.

      OK
      The difference between the displayed value and ambient temperature is below 5°C (9°F).
      Note:

      If the difference between "Coolant Temp" and the ambient temperature is 5°C (9°F) or higher, the heat from the engine affects the intake air temperature sensor, causing an incorrect value to be displayed. In this case, allow the engine to soak again.
