Hydraulic Test

HYDRAULIC TEST
Measure the line pressure

NOTE:
- Do the test at the normal operation fluid temperature of 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 transmission fluid.
2. Remove the test plug on the transaxle case front left side and connect SST (See Automatic Transmission/Transaxle/ Locations/Components for the location to connect SST).

SST 09992-00095 (09992-00231,09992-00271)

3. Fully apply the parking brake and check the 4 wheels.
4. Connect an OBD II scan tool or TOYOTA hand-held tester to the DLC3.
5. Start the engine and check the idling speed.
6. Keep your left foot pressed firmly on 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. Do the test in R position in the same way.




Specified line pressure: If the measured pressure does not reach to specified value,recheck the throttle cable and then retest.
