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 stopper outside the vehicle while the other is doing the test.

Be careful to prevent SST’s hose from interfering with the exhaust pipe.

This check must be conducted after checking and adjusting engine.

Perform under condition that A/C is OFF.

When conducting stall test, do not continue more than 10 seconds.
(1) Warm up the ATF.
(2) Remove the test plug on the left side of the trans-
axle case and connect SST.
SST 09992–00095 (09992– 00231, 09992–00271)
(3) Fully apply the parking brake and chock the 4
wheels.
(4) Connect an Intelligent Tester II to the DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake ped-
al 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.
Specified line pressure:
ConditionD position kPa (kgf / cm2, psi)R position kPa (kgf / cm2, psi)
Idling372 to 412 kPa
(3.8 to 4.2 kgf/cm2, 54 to 60 psi)
553 to 623 kPa
(5.6 to 6.4 kgf/cm2, 80 to 90 psi)
Stall test1,126 to 1,226 kPa
(11.5 to 12.5 kgf/cm2, 163 to 178 psi)
1,664 to 1,864 kPa
(17.0 to 19.0 kgf/cm2, 241 to 270 psi)
Evaluation:
ProblemPossible cause
If the measured values at all positions are higher
Shift solenoid valve SLT defective

Regulator valve detective
If the measured values at all positions are lower

Shift solenoid valve SLT defective

Regulator valve detective

Oil pump defective
If pressure is low in the D position only
D position circuit fluid leak

Forward clutch defective
If pressure is low in the R position only

R position circuit fluid leak

INSPECTION PROCEDURE
HINT:
Using the Intelligent Tester II Data List allows switch, sensor, actuator and other item values to be read with-
out removing any parts. Reading the Data List early in troubleshooting is one way to shorten labor time.
NOTICE:
In the table below, the values listed under ”Normal Condition” are reference values. Do not depend
solely on these reference values when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Intelligent Tester II to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Turn on the tester.
(f) Select the item ”Enter / Power train / Engine and ECT / Data List”.
(g) Follow the instructions on the tester and read the Data List.

HINT:
When DTC P0712 is output and Intelligent Tester II output is 150C (302F) or more, there is a short circuit.
When DTC P0713 is output and Intelligent Tester II output is –40C (–40F), there is an open circuit.
Measure the resistance between terminal THO (OT) and body ground.

  Short circuit
HINT:
If a circuit related to the ATF temperature sensor becomes open, P0713 is immediately set (in 0.5 second).
When P0713 is set, P0711 cannot be detected.
It is not necessary to inspect the circuit when P0711 is set.
