Hydraulic Test

HYDRAULIC TEST

Measure the line pressure.

NOTE:
- Conduct the test at the normal operating temperature of the ATF: 50 - 80 °C (122 - 176 °F).
- The line pressure test should always be carried out in pairs. One technician should observe the conditions of the wheels or the wheel stoppers outside the vehicle while the other is conducing the test.
- Be careful to prevent the SST's hose from interfering with the exhaust pipe.

1. Warm up the ATF.
2. Remove the test plug on the front left side of the transaxle case and connect the SST.
SST 09992-00095 (09992-00231, 09992-00271)

3. Fully apply the parking brake and check the 4 wheels.
4. Connect the OBD II scan tool or the hand-held tester to the DLC3.
5. Start the engine and check the idling speed.
6. Keep your left foot pressing firmly the brake pedal and shift into the D position.
7. Measure the line pressure when the engine is idling.
8. Depress the accelerator pedal all the way down. Quickly read the highest line pressure when the engine speed reaches the stall speed.
9. In the same manner, conduct the test in the R position.




Specified line pressure.

If the measured pressure is not up to the specified value, recheck the throttle cable adjustment and retest.
