HYDRAULIC TEST

1. PERFORM HYDRAULIC TEST






(a) Measure the line pressure.
NOTICE :
- Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature: 50 to 80°C (122 to 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 performing the test.
- Be sure to prevent SST hose from interfering with the exhaust pipe.
- This check must be conducted after checking and adjusting the engine.
- Perform the test when the A/C is OFF.
- When conducting the stall test, do not continue for more than 5 seconds.
(1) Warm up the ATF (Automatic Transmission Fluid).
(2) Remove the test plug on the transaxle case front left side and install the SST.
SST: 09992-00095
09992-00231
09992-00271
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect Techstream to the DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing 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 way, do the test in R position.
