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

(a) 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:
* This test must be conducted after checking and confirming that the engine is operating normally.
* Perform this test while the CVT transaxle fluid temperature is between 50 to 100°C (122 to 212°F).
* Perform the test with the air conditioning off.
