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. Drive the vehicle for 5 seconds or more at 9 km/h (5.59 mph) or more.
  2. Turn the engine switch off.
  3. Perform step (1) again.
  4. Check for DTCs again.

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

  1. DATA LIST 

    HINT: 

    Using 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 / SPD (SP2).
    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
      SPD (SP2) Output shaft speed Min.: 0 km/h (0 mph)
      Max.: 255 km/h (158 mph)
      Vehicle stopped: 0 km/h (0 mph) (output shaft speed equal to vehicle speed) -

      Powertrain > Engine > Data List 

      Tester Display
      SPD (SP2)

      HINT: 

      • SPD (SP2) is always 0 while driving:

        Open or short in the sensor or circuit.

      • The SPD (SP2) value displayed on the Techstream is much lower than the actual vehicle speed:

        Sensor malfunction, improper installation, or intermittent connection malfunction of the circuit.
