AUTOMATIC TRANSMISSION DIAGNOSIS
This vehicle is equipped with an electronic transmission control system, which control the automatic shift up and
shift down timing, TCC operation, etc. suitably to vehicle driving conditions.
PCM (ECM) has an On-Board Diagnosis system which detects a malfunction in this system and abnormality of
those parts that influence the engine exhaust emission.
When diagnosing a trouble in transmission including this system, be sure to have full understanding of the outline
of ªOn-board Diagnostic Systemº and each item in ªPrecaution in Diagnosing Troubleº and execute diagnosis ac-
cording to ªAUTOMATIC TRANSMISSION DIAGNOSTIC FLOW TABLEº given below to obtain correct result
smoothly.
NOTE:
There are two types of ON-BOARD DIAGNOSTIC SYSTEM de-
pending on vehicle specifications. The type of system for ve-
hicle being serviced can be identified by whether equipped
with monitor connector or not.

MANUAL ROAD TEST
This test check the gear being used in ªLº, ª2º or ªDº range when
driven with unoperated gear shift control system. Test drive vehicle
on a level road.
NOTE:
Before this test, check diagnostic trouble code (DTC).
1) Disconnect coupler of shift solenoid valves on transmission.
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when disconnecting shift solenoid
valves coupler.
2) With select lever in ªPº, start engine and warm it up.
3) With select lever in ªLº range, start vehicle and accelerate to 20
km/h (12.5 mile/h). Check in this state that 1st gear is being
used.
4) At 20 km/h (12.5 mile/h), shift select lever to 2 range and acceler-
ate to 40 km/h (25 mile/h). Check in this state that 3rd gear is
being used.
5) At 40 km/h (25 mile/h), shift select lever to D range and check
that O/D gear is used when speed is higher than 40 km/h (25
mile/h).
6) After above checks, stop vehicle then engine, and connect shift
solenoids coupler with ignition switch OFF.
WARNING:
To avoid the danger of being burned, do not touch the hot
exhaust system when connecting shift solenoid valves
coupler.
7) Clear DTC with scan tool.
TIME LAG TEST
This test is to check conditions of clutch, reverse brake and fluid
pressure. ªTime lagº means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels re-
spectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from ªNº to ªDº range
and measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from ªNº to ªRº
range.
Specification for ªNºªDºLess than 1.2 sec.
time lagªNºªRºLess than 1.5 sec.
NOTE:
When repeating this test, be sure to wait at least minute
after select lever is shifted back to ªNº range.
Engine should be warmed up fully for this test.

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 65C
(150F), 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.

6) Pull out the webbing fully as shown at the left and cut it at the
root of the pretensioner (retractor assembly) as shown in the
figure.
WARNING:
As the drum of the retractor assembly turns very quick-
ly as soon as the webbing is cut, fix the retractor assem-
bly with a vise on the workbench and keep your hands
and fingers away from it when cutting the webbing.
7) Clear a space on the ground about 185 cm (6 ft) in diameter
where the seat belt pretensioner is to be activated. A paved,
outdoor location where there is no activity is preferred. If an out-
door location is not available, a space on the shop floor where
there is no activity and sufficient ventilation is recommended.
Ensure no loose or flammable objects are within the activation
area.
8) Place the seat belt pretensioner as shown in the figure on the
ground in the space just cleared.
9) Stretch the deployment harness from the seat belt pretension-
er to its full length 10 m (33 ft).
10) Place a power source near the shorted end of the deployment
harness. Recommended application: 12 Volts minimum, 2
amps minimum. A vehicle battery is suggested.
11) Verify that the area around the seat belt pretensioner is clear
of all people and loose or flammable objects.
12) Verify that the seat belt pretensioner is placed as shown in the
figure on the ground in the space just cleared.
13) Connect the seat belt pretensioner harness to the deployment
harness connector and lock the connector with lock lever.

NOTE:
The remaining steps are to be followed in the unlikely event
that the seat belt pretensioner did not activate after following
these procedures.
23) Ensure that the deployment harness has been disconnected
from the power source and that its two banana plugs have been
shorted together by fully seating one banana plug into the oth-
er.

17) Put on a pair of shop gloves to protect your hands from possible
irritation and heat when handling the activated seat belt preten-
sioner.
NOTE:
As a precaution, gloves and safety glasses are recom-
mended to prevent any possible irritation of the skin or
eyes.
18) Disconnect the deployment harness from the seat belt preten-
sioner as soon after activation as possible. This will prevent
damage to the deployment harness due to possible contact
with the hot seat belt pretensioner canister. The deployment
harness are designed to be reused. They should, however, be
inspected for damage after each activation and replaced if nec-
essary.
19) Carefully remove drop cloth from vehicle and clean off any frag-
ments or discard drop cloth entirely.
20) Repeat steps 2) through 19) to activate seat belt pretensioner
which has not been activated, if any.
21) In the unlikely event that either or both of the seat belt preten-
sioners proceed immediately with steps 23) through 25). If the
seat belt pretensioner did activate, proceed with step 22).
22) With pretensioners activated the vehicle may be scrapped in
the same manner as a non-air bag system equipped vehicle.
23) Remove the inactivated seat belt pretensioner(s) from the ve-
hicle. Refer to SECTION 10A.
WARNING:
For handling and storage of a live seat belt pretension-

DEPLOYED AIR BAG (INFLATOR)
MODULES DISPOSAL
WARNING:
Failure to follow proper air bag (inflator) module disposal
procedures can result in air bag deployment which may
cause personal injury. Undeployed air bag (inflator) module
must not be disposed of through normal refuse channels.
The undeployed air bag (inflator) module contains sub-
stances that can cause severe illness or personal injury if
the sealed container is damaged during disposal.
Deployed air bag (inflator) modules (driver/passenger) can be dis-
posed of through normal refuse channels just like any other parts.
For their disposal, however, following points should be noted.
The air bag (inflator) module immediately after deployment is very
hot. Wait for 30 minutes to cool it off before handling it.
Never apply water, oil, etc. to deployed air bag (inflator) module
to cool it off and be careful so that water, oil etc. does not get on
the deployed air bag (inflator) module.
After the air bag (inflator) module has been deployed, the surface
of the air bag may contain a powdery residue. This powder con-
sists primarily of cornstarch (used to lubricate the bag as it in-
flates) and byproducts of the chemical reaction. As with many ser-
vice procedures, you should wear gloves and safety glasses.
When disposing of the deployed air bag (inflator) module, be sure
to seal it in a vinyl bag.
When air bag (inflator) module(s) have been deployed inside the
vehicle which is going to be scrapped, leave them as installed to
the vehicle.
Be sure to wash your hands with mild soap and water after han-
dling it.
