Caution / Notice / Hint

WARNING: This page is about a different car, the 2017 Lexus RC 350, 2017 Lexus RC 300, 2016 Lexus RC 350, 2016 Lexus RC 300, and 2015 Lexus RC 350. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

HINT: 

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.

  1. Start the engine and wait for 4 minutes and 55 seconds or more.
  2. Check for DTCs again.

    Refer to DTC CHECK / CLEAR [09/2014 - 11/2017]

  1. DATA LIST 

    HINT: 

    Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

    NOTE:

    In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

    1. Warm up the engine.
    2. Turn the engine switch off.
    3. Connect the Techstream to the DLC3.
    4. Turn the engine switch on (IG).
    5. Turn the Techstream on.
    6. Enter the following menus: Powertrain / Engine and ECT / Data List / A/T Oil Temperature 1.
    7. According to the display on the Techstream, read the "Data List".

      Powertrain > Engine > Data List 

      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      A/T Oil Temperature 1 ATF temperature sensor value Min.: -40°C (-40°F)
      Max.: 150°C (302°F)
      • After stall test: Approximately 80°C (176°F)
      • Equal to ambient temperature when engine cold
      If the value is -40°C (-40°F) or 215°C (419°F), the ATF temperature sensor circuit is open or shorted.

      Tester Display
      A/T Oil Temperature 1

      HINT: 

      • When DTC P0712 is output and Techstream output is 150°C (302°F) or more, there is a short circuit.

        When DTC P0713 is output and Techstream output is -40°C (-40°F), there is an open circuit.

        Measure the resistance between terminal OIL and body ground.

        Temperature Displayed Malfunction
        -40°C (-40°F) Open circuit
        150 °C (302°F) or more Short circuit
      • If a circuit related to the ATF temperature sensor becomes open, DTC P0713 will be stored in approximately 0.5 seconds. If DTC P0713 is stored, DTC P0711 cannot be detected.

        It is not necessary to inspect the circuit when DTC P0711 is output.
