SRS – Air Bag Modules and Clock Spring52B-29
BCLOCK SPRING INSTALLATION
Align the mating marks of the clock spring and, after turning
the front wheels to the straight-ahead position, install the
clock spring to the column switch.
Mating Mark Alignment
Turn the clock spring clockwise fully, and then turn back it
approx. 3 4/5 turns counterclockwise to align the mating marks.
Caution
If the clock spring’s mating marks are not properly aligned,
the steering wheel may not be completely rotational during
a turn, or the flat cable within the clock spring may be
severed, obstructing normal operation of the SRS and
possibly leading to serious injury to the vehicle’s driver.
CSTEERING WHEEL INSTALLATION
1. Before installation the steering wheel, be sure to first
turn the vehicle’s front wheels to the straight-ahead
position and align the mating marks of the clock spring.
Caution
Be sure when installing the steering wheel, that the
harness of the clock spring does not become caught
or tangled.
2. After clamping, turn the steering wheel all the way in
both directions to confirm that steering is normal.
DPOST-INSTALLATION INSPECTION
1. Turn the steering wheel lightly to the left and right to
check if it can be operated properly without any
abnormality.
2. Reconnect the negative battery terminal.
3. Turn the ignition key to the “ON” position.
4. Does the “SRS” warning lamp illuminate for about 7
seconds, and then remain extinguished for at least 5
seconds after turning OFF?
5. If yes, SRS system is functioning properly.
If no, consult page 52B-6.

SRS – Air Bag Module Disposal Procedures52B-36
Caution
1) Before deploying the air bag in this manner,
first check to be sure that there is no one
in or near the vehicle.
2) The inflator will be quite hot immediately
following the deployment, so wait at least 30
minutes to allow it to cool before attempting
to handle it. Although not poisonous, do not
inhale gas from air bag deployment. See
Deployed Air Bag Module Disposal
Procedures (P.52B-40) for post-deployment
handling instructions.
3) If the air bag module fails to deploy when the
procedures above are followed, do not go near
the module. Contact your local distributor.
(7) After deployment, dispose of the air bag module
according to the Deployed Air Bag Module Disposal
Procedures. (Refer to P.52B-40.)
DEPLOYMENT OUTSIDE THE VEHICLE
Caution
1. This should be carried out in a wide, flat area at least
6 m away from obstacles and other people.
2. Do not perform deployment outside, if a strong wind
is blowing, and if there is even a slight breeze, the
air bag module should be placed and deployed
downwind from the battery.
1. Disconnect the negative (–) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds after disconnecting the
battery cables before doing any further work. (Refer
to P.52B-4.).
2. Perform the following procedure to deploy each air bag
module.

(1) Remove the air bag module from the vehicle.
(Refer to P.52B-26.)
Caution
The connector of the driver’s side air bag module
is so constructed that the positive and negative
terminals are automatically short-circuited when
it is disconnected to prevent an accidental
deployment of the air bag resulting from static
electricity generation. Nevertheless, to eliminate
the slightest possibility of an accidental
deployment, always bear the following in mind;
the air bag module should be stored on a flat
surface and placed so that the pad cover face
up. Anything should not be placed on top of it.

SRS – Air Bag Module Disposal Procedures52B-39

(1) Remove the air bag module from the vehicle.
(Refer to P.52B-27.)
Caution
The connector of the front passenger’s side air
bag module is so constructed that the positive
and negative terminals are automatically
short-circuited when it is disconnected to prevent
an accidental deployment of the air bag resulting
from static electricity generation. Nevertheless,
to eliminate the slightest possibility of an
accidental deployment, always bear the following
in mind; the air bag module should be stored on
a flat surface and placed so that the pad cover
face up. Anything should not be placed on top
of it.
(2) Connect two wires, each six meters or longer, to the
two leads of SRS air bag adapter harness A and
cover the connections with insulation tape. The other
ends of the two wires should be connected to each
other (short-circuited), to prevent sudden unexpected
deployment of the air bag module.
(3) Connect the deployment wires to the SRS air bag
adaptor harness A, pass it beneath the tyre, and
wheel assembly, and connect it to the air bag module.
(4) Pass the thick wires into the hole of the air bag module
bracket, and secure it to the wheel of the old tyre
with wheel (4 locations), with the air bag facing
upwards.
Caution
1) Leave some space below the wheel for the
deployment wires.
If there is no space, the reaction of the air
bag deployment could result in damage of
the adaptor harness.
2) While deployment takes place, do not have
the connector of the SRS air bag adaptor
harness A inserted between the tyres.

Cautions in Handling Headlamp Assembly
Each headlamp assembly has a plastic outer lens on. Observe the do’s and don’ts below when
handling the headlamps.

Do not leave the headlamps lit for longer than 3 minutes with a protective cover on.

Do not mask the outer lens surface by taping or in any other way.

Do not scrub the outer lens surface with a pointed tool.

Use the designated wax remover for cleaning the outer lens surface. Rinse it thoroughly.

Use the designated genuine bulbs.

DIAGNOSIS FUNCTION
INPUT SIGNAL INSPECTION POINTS
Refer to Group 00 – How to Use Troubleshooting / Inspection Service Points.
The lighting monitor buzzer does not sound even when
the ignition key is removed with the tail lamps or
headlamps ON and the driver’s side door open. [However,
the key reminder warning buzzer sounds when inserting
the key into the ignition key cylinder.
Probable cause
The cause is probably a malfunction of the lighting switch input circuit system or
a malfunction of ETACS-ECU or buzzer ECU. When the key reminder warning buzzer
is sounding, the lighting monitor warning buzzer does not sound even if the tail lamps
or headlamps are lit.

Caution:
(1) Perform aiming adjustments, one light at a time,
with the other headlamp disconnected so as not
to be lit unless circumstances compel otherwise.
When reconnecting the headlamps, be careful not
to upset their aim. Do not leave the headlamps
on for any longer than 3 minutes if their outer

direction.
INTENSITY MEASUREMENT
1. Position the tester so that its light sensor faces each
headlamp center to center at the appropriate distance
shown.
2. Maintain an engine speed of 2,000 r/minto keep the battery
in the charged condition.
3. Check that the high-beam headlamp intensity at the center
of the high intensity zone satisfies the limit value.
Limit: 15,000 cd or more per headlamp
Caution
(1) Perform intensity measurement, one headlamp at
a time, with the low-beam lamp and the other
headlamp disconnected from the battery unless
circumstances compel otherwise. Do not leave
the headlamps on for any longer than 3 minutes
if their outer lenses are covered with a surface
covering impervious to light.
(2) Do not mask the outer lens surfaces by taping
or in any other way.
HEADLAMP BULB REPLACEMENT
1. Disconnect the connector.
2. Remove the socket cover.
3. Unhook the spring which secures the bulb, and then
remove the bulb.
Caution

27. Remove the quick joint 2 from the low-pressure service
valve.
28. Remove the service can.
NOTE
If the service can is not emptied completely, keep the
handles of the charging valve and adaptor valve 1 closed
for the next charging.
REFRIGERANT CHARGING AMOUNT CHECK
1. Start the engine.
2. Operate A/C and set the temperature control to MAX
COOL.
3. Fix the engine speed at 1,500 r/min.
4. Check the refrigerant level (bubble generation) through
the sight glass of the receiver.
ItemCondition
Proper levelBubbles are generated some times. No
bubbles appear when the engine speed is
slightly increased.
Level too lowA large amount of air bubbles are generated. If
it looks milky white, the level is excessively
lowered.
Level too highNo air bubbles appear.
5. If the level is too low, add the refrigerant, and if the level
is too high, drain the refrigerant as necessary.
Caution
Be sure to work at the low-pressure side service valve.
