TROUBLESHOOTING <F3A21>
110007115
1. TROUBLESHOOTING PROCEDURE
The cause of problems in the F3A21 is deterioration
of the oil pressure control system and defective adjustment.
(1) Establish the trouble
symptoms
1
(2) Adjustment of basic
inspection items
I (3) Road test
I
(4) Use the Troubleshooting Chart
to estimate the probable
cause
(5) Inspect the oil pres-
(6)Inspect the PJT main
Hydraulic pressure test
Stall test
sure control system
Hydraulic pressure
adjustment
(7) Confirmation test after repairs
In order to carry out diagnosis of these systems
effectively, carry out troubleshooting by the following
procedure.
(1) Gain a full understanding of the conditions under
which the trouble symptoms that the user is
complaining about occur, including frequency of
occurrence.
(2) Carry out adjustment of the basic inspection
items (ATF, throttle cable, ParWNeutral position
switch, manual control cable).
(3) Carry out a road test (P.23-9) and check the
trouble symptoms.
(4) Determine the probable cause from the
Troubleshooting Chart. (P.23-11)
Carry out the inspection of the hydraulic pressure
control system and the main body in that order.
(5) If the probable cause is in the hydraulic pressure
control system, carry out a hydraulic pressure
test.
If the result is normal, check for the probable
cause in one of the other systems.
If there is an abnormality in the oil pressure test,
carry out inspection and adjustment according to
the hydraulic pressure troubleshooting chart
(P.2360).
(6) If the probable cause is in the A A main body
system, determine which part is malfunctioning
by means of a stall test, and then carry out an
overhaul.
(7) After repairs are completed, carry out a road
test to check that the malfunction has been
repaired.

2. TORQUE CONVERTER STALL TEST
110007
This test measures the maximum engine speed when the
torque converter stalls in “ D and “ R position, and it checks
the operationof the torque converter, stator and one-way clutch
and the holding performance of the transaxle clutch (including
brake).
Caution
During this test, make sure that no one stands in front
of or behind vehicle.
(1) Check transmission fluid level. Fluid should be at normal
operating temperature [7O-8O0C (158-176”F)]. Engine
coolant should also be at normal operating temperature
[8O-9O0C (176-1 94”F)I.
(2) Apply chocks to both rear wheels.
(3) Attach engine tachometer.
(4) Apply parking and service brakes fully.
i
(5) Start engine.
I
(6) With selector lever in “ D position, depress accelerator
pedal fully to read engine maximum r/min. Do not hold
throttle wide open any longer than is necessary to obtain
maximum engine r/min. reading, and never longer than 8
seconds at a time. If more than one stall test is required,
operate engine at approximately 1,000 r/min. with selector
lever in “N” position to cool transmission fluid between
tests.
Stall speed: 1,000-2,200 r/min.
1
I
I
(7) Place selector lever to “ R position and perform stall test
by the same procedure above.
Stall Speed Above Specification in “D”
If stall speed is higher than specification, rear clutch or
overrunning clutch of transaxle is slipping. In this case, perform hydraulic test to locate cause of slippage.
1
i
Stall Speed Above Specification in “R”
f
If stall speed is higher than specification, front clutch of
transaxle or low-reverse brake is slipping. In this case, perform
hydraulic test to locate cause of slippage.
I
Stall Speed Above Specification in “D” and “R”
If stall speed is lower than specification, insufficient engine
output or faulty torque converter is suspected. Check for
engine misfiring, ignition timing, valve clearance, etc. If these
are good, torque converter is faulty.
NOTE
This procedure does not fully test the one way clutch inside
the torque converter. To complete the test for the one way
clutch, drive vehicle at 88 km/h (55 mph) and look for normal
engine rpm. If engine r/min. is abnormally high, a stuck one
way clutch is suspected.

3. HYDRAULIC PRESSURE TEST
110007045
(1) Completely warm up the transaxle.
(2) Raise the vehicle by using a jack so that the front wheels
can be rotated.
(3) Connect an engine tachometer and place it in a position
where it’s easy to see.
(4) Remove the throttle cable from the throttle lever section
of the throttle body to enable control from outside the vehicle.
(5) Attach the special tool oil pressure gauge [3,000 kPa (400
psi) type; MD998330, 1,000 kPa (140 psi) type; MD9995631
and the adapter (MD998332) to each oil pressure outlet
port.
When the reverse brake pressure is to be tested, the 3,000
kPa (400 psi) type of gauge should be used.
(6) Measure the hydraulic pressure under various conditions,
and check to be sure that the measured results are within
the standard value range shown in the “Standard Hydraulic
Pressure Table”.
If the oil pressure is not within the specified range, check
and repair as described in the “Hydraulic Pressure Troubleshooting Chart”.
(7) At an engine speed of 2,500 r/min., move the selector lever
to ‘ID range, pull the throttle cable from the idle poshon
to the fully open position and check the change in the line
pressure.
Standard value:
I
At idling 360-420 kPa (51-60 psi)
At full open 690-710 kPa (98-101 psi)

4. TORQUE CONVERTER STALL TEST
iio007071
Stall test consist of determining maximum engine speed
obtained at full throttle in “D” and “R” positions. This test
checks torque converter stator overrunning clutch operation,
and holding ability of transaxle clutches and low-reverse
brake.
Caution
During this test, make sure that no one stands in front
of or behind vehicle.
(1) Check the transmission fluid Level, fluid temperature and
engine coolant temperature.
a Fluid level: At “HOT” position in on dipstick
Fluid temperature: 70-80°C (158-176°F)
a Engine coolant temperature: 80-90°C (176- 194°F)
(2) Apply chocks to both rear wheels.
(3) Attach engine tachometer.
(4) Apply parking and service brakes fully.
(5) Start engine.
(6) With selector lever in “ D position, depress accelerator
pedal fully to read engine maximum r/min. Do not hold
throttle wide open any longer than is necessary to obtain
maximum engine r/min. reading, and never longer than 5
seconds at a time. If more than one stall test is required,
operate engine at approximately 1,000 r/min. in neutral for
2 minutes to cool transmission fluid between tests.
Standard value: 2,500-3,000 rlmin.
(7) Place selector lever to “R” position and perform stall test
by the same procedure above.
Stall Speed Above Specification in “D”
If stall speed is higher than specification, rear clutch or
overrunning clutch of transaxle is slipping. In this case, perform hydraulic test to locate cause of slippage.
Stall Speed Above Specification in “R”
If stall speed is higher than specification, front clutch of transaxle or low-reverse brake is slipping. In this case, perform
hydraulic test to locate cause of slippage.
Stall Speed Above Specification in “D” and “R”
If stall speed is lower than specification, insufficient engine
output or faulty torque converter is suspected. Check for
engine misfiring, ignition timing, valveclearance, etc. If these
are good, torque converter is faulty.
NOTE
This procedure does not fully test the one way clutch inside
the torque converter. To complete the test for the one way
clutch, drive vehicle at 88 km/h (55 mph) and look for normal
engine rpm. If engine r/min. is abnormally high, a stuck one
way clutch is suspected.

AUTOMATIC TRANSAXLE
5. HYDRAULIC PRESSURE TEST
110007134
(1) Completely warm up the transaxle.
(2) Raise the vehicle by using a jack so that the drive wheels
can be rotated.
(3) Connect an engine tachometer and place it in a position
where it’s easy to see.
(4) Attach the special oil-pressure gauge (MD998330,
MD999563) and the adapter (MD998332, MD998900) to
each oil-pressure outlet port.
When the reverse position pressure is to be tested, the
3,000 kPa (400 psi) type of gauge should be used.
(5) Measure each hydraulic pressure under the conditions in
the standard hydraulic pressure table, and check to be sure
that they are at the standard values.
(6)Use the scan tool to force-drive the actuator, and measure
the kickdown brake pressure (Apply) when the pressure
control solenoid valve (PCSV) is at 50% duty.
NOTE
1. Vehicle speed: 0 km/h (0 mph)
2. Selector lever switch position: ‘ID”
3. Accelerator condition: Fully closed.
If all of the above conditions are fulfilled, activate the
actuator for 5 seconds to bring the PCSV to 50% duty.
(7) If the pressure is outside the standard value, repair
according to the hydraulic pressure test diagnosis table.
