CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM MECHANICAL SYSTEM TESTS


  1. SHIFT TIME LAG TEST

    Note


    • This test must be performed after checking and confirming that the engine is normal.

    • Perform this test with the CVT fluid temperature between 50 and 100°C (122 and 212°F).

    • Perform this test with the air conditioning off.

    Tech Tips

    When the shift lever is moved while the engine is idling, there will be a certain time lapse or lag before shock can be felt. This is used for checking the condition of the clutches and brakes.


    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Transmission / Data List.


      Powertrain > Transmission > Data List
      Tester Display
      A/T Oil Temperature No.1

    5. Drive the vehicle until the CVT fluid temperature has reached 50 to 100°C (122 to 212°F).

    6. Allow the engine to idle with the air conditioning off.

    7. Apply the parking brake and keep the brake pedal depressed firmly.

    8. Check the D position time lag.


      1. Move the shift lever to N and wait for 1 minute.

      2. Move the shift lever to D and measure the time until shock is felt.

      3. Repeat the 2 steps above 3 times, and calculate the average time of the 3 tests.

      4. Check the R position time lag.


        1. Move the shift lever to N and wait for 1 minute.

        2. Move the shift lever to R and measure the time until shock is felt.

        3. Repeat the 2 steps above 3 times, and calculate the average time of the 3 tests.

      5. STALL SPEED TEST

        CAUTION:


        • A001VIT

          Do not perform a stall test if there are any people or objects near the vehicle.

        • The vehicle could begin moving suddenly, resulting in a serious accident.

        • A001VMJ

          Do not perform a stall test if any wheel chocks are out of position.

        • The vehicle could begin moving suddenly, resulting in a serious accident.

        • A001XRV

          Do not perform the stall test on a slippery or low-friction surface that could allow the tires to spin.

        • The vehicle could begin moving suddenly, resulting in a serious accident.

        Note


        • This test must be performed after checking and confirming that the engine is normal.

        • Perform this test with the CVT fluid temperature between 50 and 100°C (122 and 212°F).

        • Perform this test with the air conditioning off.

        • Do not perform the stall speed test for more than 5 seconds.

        • When performing the stall speed test more than once, make sure to wait 15 seconds or more between tests.

        Tech Tips

        This test is to check the overall performance of the engine and transaxle.


        1. Connect the GTS to the DLC3.

        2. Start the engine.

        3. Turn the GTS on.

        4. Enter the following menus: Powertrain / Transmission / Data List.


          Powertrain > Transmission > Data List
        6. Tester Display
        A/T Oil Temperature No.1

  • Drive the vehicle until the CVT fluid temperature has reached 50 to 100°C (122 to 212°F).

  • Allow the engine to idle with the air conditioning off.

  • Chock all 4 wheels.

  • Enter the following menus: Powertrain / Transmission / Active Test / Activate the TC Terminal.


    Powertrain > Transmission > Active Test
    Tester Display
    Activate the TC Terminal

  • Apply the parking brake and firmly depress the brake pedal with your left foot.

  • Move the shift lever to D.

  • Depress the accelerator pedal as much as possible with your right foot.

  • Quickly read the engine speed (stall speed) and release the accelerator pedal immediately.
