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 and 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

(b) Measure the time lag.
(1) 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 direct clutch, forward
clutch, and 1st and reverse brake.
NOTICE:

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

Be sure to allow 1 minute interval between tests.

Take 3 measurements and take the average value.
(2) Chock the 4 wheels.
(3) Connect the hand±held tester to DLC3 or tachome-
ter to terminal TAC of DLC3 with SST.
SST 09843±18030
(4) Start engine and check idle speed.
Idle speed: 650  50 rpm (In N range and A/C OFF)
(5) Shift the lever from N to D range. 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
(6) In the same way, measure the time lag for N
R.
Time lag: N
R less than 1.5 seconds
Evaluation (If N
D 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

U/D one±way clutch not operating properly
N
R time lag is longer

Line pressure too low

Direct clutch worn

1st and reverse brake worn

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)
Idling372 to 412 (3.8 to 4.2, 54 to 60)672 to 742 (6.9 to 7.6, 98 to 108)

Evaluation:
ProblemPossible cause
If the measured values at all ranges are higher
Shift solenoid valve SLT defective

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

Shift solenoid valve SLT defective

Regulator valve detective

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

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

R range circuit fluid leak

NOTICE:

If the glow plug breaks, the ECU detects the breakage and stops the automatic operation, so
the burner heater does not activate. (For other failures, similarly activated.)

The cause of failures (such as voltage malfunction, overheating malfunction, short±circuit or
breakage of functional components, etc.) and repair methods are shown by connecting the DTC
tester and reading the DTC.
1. DIAGNOSTICS FUNCTION
(a) Connect the DTC tester between the connector A (Vehicle harness) of DTC check harness and con-
nector B (Power heater harness).
(b) Start the engine.
(c) Pressing the DTC calling button displays a 3±digit number DTC.
