Hydraulic Test

NOTICE:
^ Be careful to prevent the oil pressure gauge hose from interfering with the exhaust pipe.
^ Perform the following tests at normal fluid operating temperature.

Normal fluid operating temperature: 50° - 8O°C (122° - 176°F)


MEASURE LINE PRESSURE

NOTICE:
^ 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.




a. Warm up the transmission fluid.
b. Remove the test plug on the transmission case left side and connect the oil pressure gauge (SST).
SST 09992-00094 - Oil pressure test kit
HINT: Connecting the oil pressure gauge will be made easier by moving LH side heat insulator side.
c. Chock the 4 wheels.
d. Fully apply the parking brake.
e. Start the engine and check idling speed.
f. Keep your left foot pressed firmly on the brake pedal and shift into D position.
g. Measure the line pressure when the engine is idling.
h. Fully depress the accelerator and quickly read and record the highest line pressure when engine speed reaches stall speed.

NOTICE: Release the accelerator pedal and stop test if the wheels begin to rotate before the engine speed reaches specified stall speed.

i. In the same manner, do the test in R position.
j. Compare your test results to the table below.




K. If the measured pressures are not up to specified values, check the No.5 solenoid valve and retest.

MEASURE ACCUMULATOR BACK PRESSURE
a. Warm up the transmission fluid.






b. Remove the test plug on the transmission case rear right side and connect the oil pressure gauge (SST).

HINT: Connecting the oil pressure gauge will be made easier by moving the RH side head insulator aside.



c. Remove the passenger side floor carpet and ECM protector.



d. Connect the SST (check harness A) between ECM and connector of vehicle wire harness.
SST: 09990-01000
e. Install one test lead probe into the terminal SLN of the ECM wire harness side connector and take care not to ground the other test lead probe.
HINT: Prepare test leads which are connected with an approximately 8 watt light bulb.



f. Fully apply the parking brake and chock the 4 wheels.
g. Start the engine and check idling speed.
h. Keep your left foot pressed firmly on the brake pedal and shift into D position.
i. Measure the accumulator back pressure.
j. In the same condition, ground the other probe or the test lead which has one end inserted into the terminal SLN of the ECM harness side connector, then measure the accumulator back pressure again.
K. Compare your results to the following table.
