CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM HYDRAULIC TEST


  1. PERFORM HYDRAULIC TEST

    Tech Tips

    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.

      Note


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

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

      • Perform these tests with the A/C off.

      • 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.

      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.

        11. Tech Tips

        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.
