CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM MECHANICAL SYSTEM TESTS


  1. SHIFT TIME LAG TEST

    Note


    • Be sure to inspect and adjust the engine before performing these tests.

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

    • Perform these tests with the A/C off.

    Tech Tips

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


    1. Connect the GTS to the DLC3.

    2. Start the engine.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List.

    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. Set 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 the 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 the 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:

        The stall speed test should always be performed with at least 2 people. One person should observe the condition of the wheels and wheel chocks while the other is performing the test.

        Note


        • The stall speed test should be done on a paved surface (a surface that is not slippery).

        • To ensure safety, perform this test in an open and level area that provides good traction.

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

        Tech Tips


        • Depending on the vehicle conditions, actual results may vary beyond the specified ranges. This does not necessarily indicate a malfunction.

        • This test is to check the overall performance of the engine.


        1. Connect the GTS to the DLC3.

        2. Start the engine.

        3. Turn the GTS on.

        4. Enter the following menus: Powertrain / Engine and ECT / Data List.

        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. Chock all 4 wheels.

        8. Set the parking brake and keep the brake pedal firmly depressed with your left foot.

        9. Move the shift lever to D.

        10. Depress the accelerator pedal all the way down with your right foot.

        11. Read the engine rpm (stall speed) and release the accelerator pedal immediately.
