PERFORM HYDRAULIC TEST

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

  1. Measure the secondary oil pressure.

    CAUTION:
    The secondary oil pressure test should always be carried out with at least 2 people. One person should observe the condition of wheels and wheel chocks while the other is performing the test.

    NOTICE:
    1. This test must be conducted after checking and confirming that the engine is operating normally.
    2. Perform this test while the CVT transaxle fluid temperature is between 50 to 100°C (122 to 212°F).
    3. Perform the test with the air conditioning off.
    4. Do not perform the stall test for longer than 5 seconds.


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

    2. Connect the intelligent tester to the DLC3.

    3. Start the engine.

    4. Turn the tester on.

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

    6. Select the Data List menu: A/T Oil Pressure from Engine and ECT.

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

    8. 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.

      Specified Secondary Oil Pressure:

      Condition
      		MPa (kgf/cm2, psi)
      		Engine Speed
      D position stall test
      		3.78 to 5.89 MPa
      (38.5 to 60.1 kgf/cm2, 548 to 854 psi)
      		1850 to 2650 rpm

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

    10. 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.

      Specified Secondary Oil Pressure:

      Condition
      		MPa (kgf/cm2, psi)
      		Engine Speed
      R position stall test
      		3.78 to 6.20 MPa
      (38.5 to 63.2 kgf/cm2, 548 to 899 psi
      		1850 to 2650 rpm

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