СИСТЕМА БЕССТУПЕНЧАТОЙ ТРАНСМИССИИ ПРОВЕРКА МАГИСТРАЛЬНОГО ДАВЛЕНИЯ


  1. PERFORM HYDRAULIC TEST


    1. Measure the secondary oil pressure.

      CAUTION:

      A secondary oil pressure test should always be carried out 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


      • 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 repeatedly, wait for 15 seconds or more between tests.

      • Perform this test with the AUTO function (shift-linked function) of the electronic parking brake system off.


      1. Fully apply the parking brake and chock all 4 wheels.

        Tech Tips

        When the electric parking brake switch (combination switch assembly) is pulled to the lock side 2 times (2 lock operations), the maximum amount of braking force is applied.

      2. Connect the GTS to the DLC3.

      3. Start the engine.

      4. Turn the GTS on.

      5. Enter the following menus: Powertrain / Engine and ECT / Active Test / Connect the TC and TE1.

        Tech Tips

        Observe the value of A/T Oil Pressure in the Data List on the screen while performing the Active Test.


        Powertrain > Engine > Active Test
        Active Test Display
        Connect the TC and TE1
        Data List Display
        A/T Oil Pressure

      6. Keep your left foot firmly on the brake pedal and move the shift lever to D.

      7. Depress the accelerator pedal as much as possible with your right foot. Quickly read the highest secondary oil pressure reading when the engine speed reaches stall speed and release the accelerator pedal immediately.

      8. Keep your left foot firmly on the brake pedal and move the shift lever to R.

      9. Depress the accelerator pedal as much as possible with your right foot. Quickly read the highest secondary oil pressure reading when the engine speed reaches stall speed and release the accelerator pedal immediately.

        Specified Secondary Oil Pressure
        Shift Lever Position Secondary Oil Pressure
        D

        4.2 to 5.5 MPa

        (42.8 to 56.1 kgf/cm2, 609 to 798 psi)
        R

        3.1 to 4.5 MPa

        (31.6 to 45.9 kgf/cm2, 449 to 653 psi)

        Tech Tips

        If the secondary oil pressure exceeds the maximum value or drops below the minimum value, a solenoid valve, regulator valve or modulator valve may be malfunctioning.
