Hydraulic Test

Measure the line pressure.

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

1. Warm up the ATF.
2. Remove the test plug on the transaxle case front left side and connect SST.
SST 09992-00095 (09992-00231, 09992-00271)
3. Fully apply the parking brake and chock the 4 wheels.
4. Connect an OBD II scan tool or LEXUS hand-held tester to DLC3.
5. Start the engine and check idling speed.
6. Keep your left foot pressed firmly on the brake pedal and shift into 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 engine speed reaches stall speed.
9. In the same manner, do the test in R position.




Specified line pressure

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