INSPECTION PROCEDURE
HINT:
Start the inspection from step 1 if you are using the hand±held tester and\
start from step 2 if you are not using
the hand±held tester.
1READ VALUE OF MASTER CYLINDER PRESSURE SENSOR
(a)Select the DATALIST mode on the hand±held tester.
(b)Check that the brake fluid pressure value of the No.1 master cylinder pressur\
e sensor and No.2 master
cylinder pressure sensor displayed on the hand±held tester changes wh\
en depressing the brake ped-
al.
OK:
Brake fluid pressure value is changing.
OKGo to step 4

4. DATA LIST
HINT:
According to the DATA LIST displayed by the hand±held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
of the methods to shorten the work time.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) According to the display on tester, read the ºDATA LISTº.

8. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R ranges.
NOTICE:

Do the test at normal operating ATF temperature 50 to 80
C (122 to 176
F).

Do not continuously run this test for longer than 5 seconds.

To ensure safety, do this test in a wide, clear level area which provides good traction.

The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect the hand±held tester to DLC3 or tachome-
ter to terminal TAC of DLC3 with SST.
SST 09843±18030
(3) Fully apply the parking brake.
(4) Keep your left foot pressing firmly on the brake ped-
al.
(5) Start the engine.
(6) Shift into the D range. Press all the way down on the
accelerator pedal with your right foot.
(7) Quickly read the stall speed at this time.
Stall speed: 2,550
150 rpm
(8) Do the same test in the R range.
Stall speed: 2,550
150 rpm
Evaluation:
ProblemPossible cause
(a) Stall speed low in D and R ranges

Engine output may be insufficient

Stator one±way clutch not operating properly
HINT: If more than 600 rpm below the specified value, the torque
converter could be faulty.
(b) Stall speed high in D range

Line pressure too low

Forward clutch slipping

No. 2 one±way clutch not operating properly

U/D clutch slipping
(c) Stall speed high in R range

Line pressure too low

Direct clutch slipping

1st & reverse brake slipping

U/D clutch slipping
(d) Stall speed high in D and R ranges

Line pressure too low

Improper fluid level

U/D one±way clutch not operating properly

9. HYDRAULIC TEST
(a) Measure the line pressure.
NOTICE:

Do the test at normal operation ATF 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.
(1) Warm up the ATF.
(2) Remove the test plug on the rear 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 the hand±held tester to 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 range.
(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 range.
Specified line pressure:
ConditionD range kPa (kgf / cm2, psi)R range kPa (kgf / cm2, psi)
