CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM HYDRAULIC TEST

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 more than once, make sure to wait 15 seconds or more between tests.

2. Measure the secondary oil pressure.

   
   

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

   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 / Data List / A/T Oil Pressure.

      Tech Tips

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

   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.

      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.
