6. 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 positions.
NOTICE:

Do the test at normal operating fluid temperature 50 ± 80 °C (122 ± 176 °F).

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

To ensure safety, conduct 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 an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot depressing firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
Quickly read the stall speed at this time.
Stall speed: 2,450 ± 150 rpm
(7) Do the same test in R position.
Stall speed: 2,450 ± 150 rpm
Evaluation:
ProblemPossible cause
(a) Stall speed low in D and R positions

Engine output may be insufficient

Stator one±way clutch is operating properly

HINT: If more than 600 rpm below the specified value, the torque
converter clutch could be faulty.
(b) Stall speed high in D position

Line pressure too low

Forward clutch slipping

No.2 one±way clutch not operating properly

O/D clutch slipping
(c) Stall speed high in R position

Line pressure too low

Direct clutch slipping

1st & reverse brake slipping

O/D clutch slipping
(d) Stall speed high in D and R positions

Line pressure too low

Improper fluid level

O/D one±way clutch not operating properly

(b) Measure the time lag.
When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before
the shock can be felt. This is used for checking the condition of the O/D direct clutch, forward clutch,
and 1st & reverse brake.
NOTICE:

Do the test at normal operating fluid temperature 50 ± 80 °C (122 ± 176 °F).

Be sure to allow 1 minute interval between tests.

Take 3 measurements and take the average value.
(1) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(2) Fully apply the parking brake.
(3) Start the engine and check idle speed.
Idle speed : 750 ± 50 rpm (In N position and air conditioner OFF)
(4) Shift the shift lever from N to D position. Using a stop watch, measure the time from when the
lever is shifted until the shock is felt.
Time lag: N " D Less than 1.2 seconds
(5) In the same manner, measure the time lag for N " R.
Time lag: N " R Less than 1.5 seconds
Evaluation (If N " D time or N " R time lag is longer than the specified):
ProblemPossible cause
N " D time lag is longer

Line pressure too low

Forward clutch worn

O/D one±way clutch not operating
N " R time lag is longer

Line pressure too low

Direct clutch worn

1st & reverse brake worn

O/D one±way clutch not operating properly

7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:

Do the test at normal operation fluid temperature 50 ± 80 °C (122 ± 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 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 transaxle case front left side and connect SST.
(See page AX±17 for the location to connect SST)
SST 09992±00095 (09992±00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake pedal 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 manner, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf/cm2, psi)R position kPa (kgf/cm2, psi)
Idling362 ± 422 (3.7 ± 4.3, 53 ± 61)618 ± 794 (6.3 ± 8.1, 90 ± 115)
Stall735 ± 862 (7.5 ± 8.8, 107 ± 125)1,373 ± 1,608 (14.0 ± 16.4, 199 ± 233)
If the measured pressure is not up to the specified value, recheck the throttle cable adjustment and retest.
Evaluation
ProblemPossible cause
If the measured values at all positions are higher

Throttle cable out of adjustment

Throttle valve defective

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

Throttle cable out of adjustment

Throttle valve defective

Regulator valve defective

Oil pump defective

O/D direct clutch defective
If pressure is low in the D position only
D position circuit fluid leakage

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

R position circuit fluid leakage

Direct clutch defective

1st & reverse brake defective

PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the DTC check but the trouble still occurs, check the circuits for each
symptom in the order given in the charts on the following pages and proceed to the page given for trouble-
shooting.
The Matrix Chart is divided into 3 chapters.
Chapter 1: Electronic Circuit Matrix Chart
Chapter 2: On±vehicle Repair Matrix Chart
Chapter 3: Off±vehicle repair Matrix Chart
If the instruction ºProceed to next circuit inspection shown on matrix chartº is given in the flow
chart for each circuit, proceed to the circuit with the next highest number in the table to continue
the check.
If the trouble still occurs even though there are no abnormalities in any of the other circuits, then
check and replace the ECM.
