U151F AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: HYDRAULIC TEST

HYDRAULIC TEST





1. PERFORM HYDRAULIC TEST
(a) Measure the line pressure.
- Perform the test at the normal operating ATF temperature: 50 to 80°C (122 to 176°F).
- The line pressure test should always be performed with at least 2 people. One person should observe the condition of the wheels or wheel chocks while the other is performing the test.
- Be careful to prevent SST's hose from interfering with the exhaust pipe.
- This test must be performed after checking and adjusting the engine.
- Perform the test with the A/C OFF.
- When conducting the stall test, do not continue for more than 10 seconds.
(1) Warm up the ATF (Automatic Transmission Fluid).
(2) Lift the vehicle up.
(3) Remove the engine under cover.
(4) Connect Techstream to the DLC3.
(5) Remove the test plug A on the transaxle case front left side and install SST.
SST: 09992-00095
09992-00231
09992-00271
NOTE: There is a difference between the installation point of the D position and R position.
(6) Start the engine.
(7) Using Techstream, shift to D position and hold 3rd gear by active test, and measure the line pressure in idling.





(8) Turn the ignition switch off.
(9) Disconnect the connector of the transmission wire.
HINT: Disconnect the connector only when performing the D position stall test.

(10) Start the engine.
(11) Firmly depress the brake pedal, shift to the D position, depress the accelerator pedal all the way down and check the line pressure while the stall test is performed.






(12) Turn the ignition switch off.
(13) Remove SST, and install the test plug A.
(14) Remove the test plug B, install SST and start the engine.
SST: 09992-00095
09992-00231
09992-00271
(15) Connect the transmission wire connector, depress the brake pedal firmly, shift to the R position and check the line pressure while the engine is idling and during the stall test.






(16) Remove SST, and install the test plug B.
(17) Clear the DTC.
