.”Raise the vehicle by using a jack so that the drive wheels
can be rotated.
Connect an engine tachometer and place it in a position
where it’s easy to see.
Attach the special oil-pressure gauge
(C-3292 or C-3293)and the adaptor
(MD998332) to each oil-pressure outlet
port.When the reverse pressure is to be tested, the 3,000
kPa(400 psi) type of gauge should be used.
Measure the oil pressure under various conditions , and
check to be sure that the measured results are within the
standard value range shown in the “Standard oil pressure
table” below.
If the oil pressure is not within the specified range, check
and repair as described in the section “Remedial steps if oilpressure is not normal” on the next page.

21-202AUTOMATIC TRANSAXLE - Troubleshooting
CONVERTER STALL TESTStall 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-reserve brake.
CautionDuring this test, make sure that no one stand in
front of or behind vehicle.
1. Check transaxle fluid level. Fluid should be at
normal operating temperature
[70-80°C (160-
18O”F)]. Engine coolant should also be at normaloperating temperature
[80-90°C (180- 19O”F)l.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
rpm. Do not hold throttle wide open any longer
than is necessary to obtain maximum engine
rpm reading, and never longer than 5 seconds ata time. If more than one stall test is required,
operate engine at approximatey 1,000 rpm in
neutral for 2 minutes to cool transaxle fluid
between tests.
Stall speed:
1,800-3,200 rpm
TRANSAXLE CONTROL7. Place selector lever to “R” position and perform
?+stall test by the same procedure as in foregoing
-,
item.Stall Speed Above Specification in “D”
If stall speed is higher than specification, rear clutchor overrunning clutch of transaxle is slipping. In this
case, perform hydraulic test to locate cause of
slippage.Stall Speed Above Specifjcation 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 Below Specification in “D” and “R”
If stall speed is lower than specification, insufficient
engine output or faulty torque converter is sus-
pected. Check for engine misfiring, ignition timing,
valve clearance etc. If these are good, torque
converter is faulty.

INSTRUCTIONS FOR ALUMINUM TYPE
WHEELSUzzGfM
1. Aluminum is vulnerable to alkalies. If a vehicle
washing detergent has been used, or salt from
sea water or road chemicals has adhered, washthe vehicle as soon as possible. After washing
the vehicle, apply body or wheel wax to the
aluminum type wheels to prevent corrosion.
2. When cleaning the vehicle with steam, do not
direct steam onto the aluminum type wheels.
When tightening nuts for aluminum type
wheels, particularly observe the following:
(1) Clean the hub surface of aluminum type
wheels.(2) After finger-tightening wheel nuts, tighten
them to specifications.
(3) Do not use an impact wrench or push the
wrench by foot to tighten the wheel nuts.
(4) Do not apply oil to the threaded portions.
INSTRUCTIONS FOR TIRE CHAINS AND
SNOW TIRESNZZGGAA
1.Use tire chains only on front wheels. Do not usetire chains on rear wheels.
2. When using snow tires, use them on all four
wheels for maneuverability and safety.
INSTRUCTIONS FOR COMPACT SPARE
TIRE;c.1. The compact spare tire is designed to. save
space in the luggage compartment, and its
L’lighter weight makes it easier to use if a fiat tire
occurs.
2.The following instructions for the compact sparetire should be observed.
(1) Check the inflation pressure after installing
the spare, and adjust to the specified pres-
sure.(2) Avoid driving through automatic car washes
and over obstacles that could possibly dam-
age the vehicle’s undercarriage. Because
the tire is smaller than the original tire, car
ground clearance is slightly reduced.
(3) The compact spare tire should not be used
on any other wheels, nor should standard
tires, snow tires, wheel covers or trim rings
be used with the compact spare wheel. If
such use is attempted, damage to these
items or other vehicle components may
occur.

BODY - Service Adiistment Procedures23-33
Front floor pan18AO510
?ear floor pan

FLOOR PAN INSPECTIONN23FlACA common result of body leaks is a soaked floor mat pad or
carpet, and it’s not unusual to find that the water is getting in
through the floor pan to some other low point in the body. It is
possible however, for water to enter higher up and run
downward to soak the mat.
Since a soaked mat should be removed for drying, it’s a good
way to start your check. Of course, mat removal means you’ll
have to take off door sill plates and pull out seats or seat cushion.
But, this gives you a clear field for action so you can check bodyseam sealing and the plugs in the floor pan.
It’s usually not practical to water test for floor pan or
wheelhousing leaks unless a special underbody water spray
arrangement is available. As an alternate, the best way to locate
these leak points is to look for rusty seam edges or other traces
of leaks after the mats and cushions are removed. Traces of mudare an indication that the water is coming in from below.
WATER TESTN23FPABs1. Close roof lid tightly.
2.Hold hose upward and adjust water fountain to about 50 cm
(20 in.) high.
3. Pour water over the roof from about 30
cm (12 in.) above
roof for more than 5 minutes.
4. While pouring water, check for leak around roof lid.
5. In the event of leakage, check drain hose, weatherstrip
contact and others.

IDLE-UP OPERATION CHECKN24FoAA
(I) Before inspection and adjustment set vehicle in the
following condition:
l Engine coolant temperature:
80-90°C (176-194°F)
lLights, electric cooling fan and accessories: Set to OFFl Transaxle: Neutral
(N or P for vehicles with A/T)l Steering wheel: Straightforward
(2) Check whether or not the idling speed is the standard
value.Standard value:
4.8L Engine>700 rpm
<2.0L DOHC Engine>750 rpm
NOTE
There is no necessity to make an adjustment, because theidling speed is automatically adjusted by the
ISC” system.
If, however, there occurs a deviation from the standard
value for some reason, check the
ISC” system.
(3) Check to be sure that the idlig speed becomes the standardvalue when the air conditioner switch is switched ON and
the air conditioner is activated.
Standard value: 850 rpm
NOTE
There is no necessity to make an adjustment, because theidling speed is automatically adjusted by the
ISC” system.
If, however, there occurs a deviation from the standard
value for some reason, check the
ISC” system.
