WARNING: This page does not describe the selected car, but rather 14 other vehicles, including the 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 350, 2023 Lexus IS 300, and 2022 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK IF OTHER DTCS OUTPUT 
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Transmission / Trouble Codes.

      Powertrain > Transmission > Trouble Codes 

    5. Read the DTCs using the Techstream.

      Result

      Result Proceed to
      • Only DTCs P0894-00 is output
      • Only DTCs P0894-00 and P2713-7F are output
      		 A
      P0894-00, P2713-7F and other DTCs are output B

      HINT: 

      If any DTCs other than P0894-00 and P2713-7F are output, perform troubleshooting for those DTCs first.

    Result: 

    B 

    GO TO DTC CHART. Refer to  DIAGNOSTIC TROUBLE CODE CHART [10/2017 - 09/2018]  , or refer to  DIAGNOSTIC TROUBLE CODE CHART [09/2018 - 09/2019] 

    Result: 

    A 

    See step  2

  2. PERFORM ACTIVE TEST USING TECHSTREAM 
    NOTE:
    • Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature: 50 to 80°C (122 to 176°F)
    • Be careful to prevent the SST hose from interfering with the exhaust pipe.
    • This check must be conducted after checking and confirming that the engine is normal.
    • Perform the test with the air conditioning off.

    HINT: 

    Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

    1. Turn the engine switch off.
    2. Lift the vehicle up.
    3. Remove the test plug from the transmission case and connect SST.

    4. Lower the vehicle.
    5. Fully apply the parking brake and chock all 4 wheels.
    6. Connect the Techstream to the DLC3.
    7. Start the engine.
    8. Warm up the ATF (Automatic Transmission Fluid).
    9. Measure the line pressure when the engine is idling.
    10. Turn the Techstream on.
    11. Enter the following menus: Powertrain / Transmission / Active Test.
    12. According to the display on the Techstream, perform the "Active Test".
    13. Measure the line pressure with SST.

      Activate the Solenoid (SLT)

      "Activate the Solenoid (SLT)" in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transmission, which is used in the HYDRAULIC TEST as well.

      Refer to HYDRAULIC TEST [10/2017 - 09/2020]

      HINT: 

      The pressure values in Active Test and HYDRAULIC TEST are different from each other.

      OK

      The line pressure changes as specified when performing the Active Test.

  3. PERFORM ACTIVE TEST USING TECHSTREAM 
    WARNING:

    This test should always be performed with at least 2 people.

    NOTE:
    • Perform the test while the ATF temperature is between 50 and 80°C (122 and 176°F).
    • Perform the test with the air conditioning off.

    HINT: 

    Using the Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

    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 / Transmission / Active Test.

      HINT: 

      While driving, the shift position can be forcibly changed with the Techstream. Comparing the shift position commanded by the Active Test with the actual shift position enables you to confirm the problem.

      Refer to FAIL-SAFE CHART [10/2017 - ]

    7. According to the display on the Techstream, perform the "Active Test".
