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 engine.
- Perform the test with the A/C is OFF.
- When conducting stall test, do not continue more than 5 seconds.
(1) Warm up the ATF (Automatic Transmission Fluid).
(2) Lift the vehicle up.
(3) Remove the engine under cover.
(4) Connect the Techstream to the DLC3.
(5) Remove the test plug on the transaxle case front left side and install the SST.
SST: 09992-00095
09992-00231
09992-00271
(6) Start the engine.
(7) Shift to the D position, and then use the Techstream to hold 3rd gear using active test. Measure the line pressure while the engine is idling.

Specified line pressure:





(8) Turn the ignition switch OFF.




(9) Disconnect the connector of the TCM.
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.

Specified line pressure:





(12) Turn the ignition switch OFF.
(13) Connect the TCM connector, depress the brake pedal firmly, shift to the R position, and check that the line pressure while the engine is idling and during the stall test.

Specified line pressure:





(14) Remove the SST, install the test plug.
(15) Clear the DTC.

Specified line pressure:
