STALL TEST
This test is to check overall performance of automatic transmission
and engine by measuring stall speed at ªDº and ªRº ranges. Be sure
to perform this test only when transmission fluid is at normal operat-
ing temperature and its level is between FULL and LOW marks.
CAUTION:

Do not run engine at stall more than 5 seconds continu-
ously, for fluid temperature may rise excessively high.

After performing stall test, be sure to leave engine running
at idle for longer than 30 seconds before another stall test.
1) Apply parking brake and block wheels.
2) Install tachometer.
3) Start engine with select lever shifted to ªPº.
4) Depress brake pedal fully.
5) Shift select lever to ªDº and depress accelerator pedal fully while
watching tachometer. Read engine rpm quickly when it has be-
come constant (stall speed).
6) Release accelerator pedal immediately after stall speed is
checked.
7) In the same way, check stall speed in ªRº range.

LEVEL CHECK AT ROOM TEMPERATURE
The fluid level check at room temperature performed after repair or
fluid change before test driving is just preparation for level check of
normal operating temperature. The checking procedure itself is the
same as that described previously. If the fluid level is between FULL
COLD and LOW COLD, proceed to test drive. And when the fluid
temperature has reached the normal operating temperature, check
fluid level again and adjust it as necessary.
FLUID CHANGE
1) Lift up vehicle.
2) With engine is cool, remove drain plug from oil pan and drain A / T
fluid.
3) Install drain plug.

ON-VEHICLE SERVICE
MAINTENANCE SERVICE
NOTE:

When having driven through water, check immediately if wa-
ter has entered (if so, oil is cloudy). Water mixed oil must be
changed at once.

Whenever vehicle is hoisted for any other service work than
oil change, also be sure to check for oil leakage and status
of breather hoses.
Gear Oil Change
NOTE:

Hypoid gear oil must be used for differential.

It is highly recommended to use SAE 80W ± 90 viscosity.
1) Before oil change or inspection, be sure to stop engine and lift
up vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found, cor-
rect its cause.
3) Drain old oil and pour proper amount of gear oil as specified be-
low (roughly up to level hole).
4) Apply sealant to thread of drain plug (b) and torque plugs to
specification.

INSPECTION
1) Warm up ECT sensor (1) observing resistance between sensor
terminal (2) and sensor unit (1). Resistance should be de-
creased with increase of its temperature.
2) Check resistance between sensor terminal (2) and sensor unit
(1) shown below. If check result is not as specified, replace sen-
sor.

CAUTION:
Never touch terminals of Immobilizer Control Module it-
self or connect voltmeter or ohmmeter.
2) Check resistance between each terminal of coupler discon-
nected.
CAUTION:

Be sure to connect ohmmeter probe from wire harness
side of coupler.

Be sure to turn OFF ignition switch for this check.

PRECAUTIONS IN HANDLING IMMOBILIZER
CONTROL SYSTEM

Do not turn ON ignition switch with ignition key for immobilizer
control system put together with another one or placed quite close
to another one. Or the system may detect abnormal condition and
prevent engine from starting.

Do not turn ON ignition switch by using ignition key with any type
of metal wound around its grip or in contact with it. Or the system
may detect abnormal condition and prevent engine from starting.

Do not leave ignition key where high temperature is anticipated.
High temperature will cause transponder in ignition key to be ab-
normal or damaged.

Do not turn ON ignition switch with a radio antenna placed near
coil antenna or its harness to Immobilizer Control Module. Or the
system may detect abnormal condition and prevent engine from
starting.

ALWAYS CARRY AIR BAG (INFLATOR) MODULE
WITH TRIM COVER (AIR BAG OPENING) AWAY
FROM BODY.
10B-58 AIR BAG SYSTEM
LIVE (UNDEPLOYED) AIR BAG (INFLATOR) MODULES
Special care is necessary when handling and storing a live (unde-
ployed) air bag (inflator) modules.
The rapid gas generation produced during deployment of the air
bag could cause the air bag (inflator) module, or an object in front
of the air bag (inflator) module, to be thrown through the air in the
unlikely event of an accidental deployment.
WARNING:
Never attempt to measure the resistance of the air bag (in-
flator) modules (driver and passenger). It is very dangerous
as the electric current from the tester may deploy the air
bag.

Never attempt disassembly of the air bag (inflator) modules.

If any abnormality is found, be sure to replace it with new one as
an assembly.

When an abnormality is noted as existing in the live (undeployed)
air bag (inflator) module, be sure to deploy it before discarding it.

When grease, cleaning agent, oil, water, etc., got on the air bag
(inflator) modules (driver and passenger), wipe it off immediately
with a dry cloth.

If air bag (inflator) module was dropped from a height of 90 cm (3
ft) or more, it should be replaced with a new one as an assembly.
WARNING:

For handling and storage of a live air bag (inflator) module,
select a place where the ambient temperature below 65
C
(150
F), without high humidity and away from electric
noise.

When carrying a live air bag (inflator) module, make sure
the bag opening is pointed away from you. In case of an
accidental deployment, the bag will then deploy with mini-
mal chance of injury. Never carry the air bag (inflator)
module by the wires or connector on the underside of the
module.
Otherwise, personal injury may result.

Never attempt to disassemble the seat belt pretensioners (retrac-
tor assembly).

If any abnormality is found, be sure to replace it with new one as
an assembly.

When an abnormality is noted as existing in the live (inactivated)
seat belt pretensioner, be sure to activate it before discarding it.

When grease, cleaning agent oil, water, etc., got on the seat belt
pretensioners (retractor assembly), wipe it off immediately with a
dry cloth.

If seat belt pretensioner was dropped from a height of 30 cm (1
ft) or more, it should be replaced with a new one as an assembly.
WARNING:

For handling and storage of a live seat belt pretensioner,
select a place where the ambient temperature below 65
C
(150
F), without high humidity and away from electric
noise.

Never carry the seat belt pretensioner by the wires or con-
nector on the underside of the pretensioner.

When placing a live seat belt pretensioner on the work-
bench or some place like that, be sure not to lay it with its
exhaust hole provided side facing down. It is also prohib-
ited to put something on its face with an exhaust hole or
to put a seat belt pretensioner on top of another.
Otherwise, personal injury may result.
