SRS – SRS-ECU / Air Bag Modules and Clock Spring52B-25
INSTALLATION SERVICE POINTS
ASRS-ECU INSTALLATION
Caution
The SRS may not activate if SRS-ECU is not installed
properly, which could result in serious injury or death
to the vehicle’s driver or front passenger.
BPOST-INSTALLATION INSPECTION
1. Reconnect the negative battery terminal.
2. Turn the ignition key to the “ON” position.
3. Does the “SRS” warning lamp illuminate for about 7
seconds, and then remain extinguished for at least 5
seconds after turning OFF?
4. If yes, SRS system is functioning properly.
If no, consult page 52B-6.
INSPECTION

Check the SRS-ECU and brackets for dents, cracks or
deformation.

Check connector for damage, and terminals for
deformation.
Caution
If a dent, crack, deformation or rust is discovered,
replace the SRS-ECU with a new one.
NOTE
For checking of the SRS-ECU other than described above,
refer to the section concerning troubleshooting. (Refer
to P.52B-6.)
AIR BAG MODULES AND CLOCK SPRING
Caution
1. Disconnect the battery (–) terminal and wait
for 60 seconds or more before starting work.
Furthermore, the disconnected battery
terminal should be covered with tape to
insulate it. (Refer to P.52B-3.)
2. Never attempt to disassemble or repair the
air bag modules or clock spring.
If faulty, replace it.
3. Do not drop the air bag modules or clock
spring or allow contact with water, grease
or oil.
Replace it if a dent, crack, deformation or
rust is detected.
4. The air bag modules should be stored on
a flat surface and placed so that the pad
surface is facing upward.
Do not place anything on top of it.5. Do not expose the air bag modules to
temperatures over 93C.
6. Both driver’s side and front passenger’s
side air bag modules should be replaced
with new ones once the respective air bags
were deployed. The clock springs should
also be checked and replaced with new ones
if considered abnormal.
7. Wear gloves and safety glasses when
handling air bags that have already
deployed.
8. An undeployed air bag module should only
be disposed of in accordance with the
procedures (Refer to P.52B-32.)

(5) Place three old tyres, without wheels, on top of the
tyre secured to the air bag module, and secure all
tyres with ropes (4 locations).
NOTE
The front passenger’s side air bag is larger in capacity
than the driver’s side air bag when deployed. For
this reason, it is necessary to tie up all tyres together
with rope.
(6) At a location as far away from the air bag module
as possible, and from a shielded position, disconnect
the two connected wires from each other, and connect
them to the two terminals of the battery (which has
been removed from the vehicle) to deploy the air
bag.
Caution
1) Before deployment, check carefully to be sure
that no one is nearby.
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 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.
DEPLOYED AIR BAG MODULE DISPOSAL
PROCEDURES
After deployment, the air bag module should be disposed
of in the same manner as any other scrap parts, adhering
to local laws and/or legislation that may be in force except
that the following points should be carefully noted during
disposal.
1. The inflator will be quite hot immediately following
deployment, so wait at least 30 minutes to allow it cool
before attempting to handle it.
2. Do not put water or oil on the air bag after deployment.

TROUBLESHOOTING
There is noise when the engine is running.
Kind of Noise (Parenthe-
sized is how noise
sounds.)SymptomCauseRemedy
AM, FM: Ignition noise
(Popping, snapping,
crackling, buzzing)
Popping sound becomes
faster with the increase
of engine speed.

The noise is lost with
ignition switch turned to
ACC.
Mainly due to the
spark plugs.

Due to noise circula-
tion from elsewhere

Noise from the engineCheck the noise capacitor
and earth cable and
replace if necessary. (See
Fig. 1 and Fig. 2.)
AM, FM: Defogger noise
(1) (Murmuring)Occurs when the defogger
switch is turned to ON and
OFF.Noise produced by spark-
ing when the defogger
switch is turned to ON/
OFF enters the glass
antenna.Check the noise capacitor
and replace if necessary.
(See Fig. 1.)
AM, FM: Defogger noise
(2) (Snapping noise)Occurs when the defogger
switch is turned to ON.Noise produced by current
flowing in the defogger
enters the glass antenna.Check the choke coil and
replace if necessary.
(See Fig. 3.)
AM, FM: Defogger noise
(3) (Scratching, gaggling)Occurs when the defogger
switch is turned to ON with
print heater wire broken.Noise produced by spark-
ing where print heater is
broken enters the glass
antenna.Repair the print heater.
AM, FM: Wiper motor
noise (Humming, wheez-
ing)Sound becomes faster with
the increase of wiper speed
and is lost when the wiper is
stopped.Caused by sparking in
wiper motor brush.Replace the wiper motor.
FM: Mirror motor noise
(Humming, wheezing)Occurs when electric mirror
operates.Caused by sparking in
mirror motor brush.Replace the electric
motor.
Other electrical compo-
nents–Noise is emitted by some
electrical components in
long use.Repair or replace electri-
cal components.
Static electricity (Crack-
ling, crinkling)
Noise is stopped when
the vehicle comes to a
complete stop.

Noise becomes louder
when the clutch is
released.Occurs when parts or
wiring move for some
reason and contact metal
parts of the body.Put parts or wiring into
position.
Various noises are produced
by body parts.Due to electrical detach-
ment of the hood, exhaust
pipe and muffler, suspen-
sion, etc. from the body.Tighten mounting bolts
securely. In many cases,
remedy of one part does
not eliminate the problem
due to incomplete earthing
elsewhere.
Caution
(1) Never let the noise filter contact a high tension cable. The noise filter could break down.
(2) Check that there is no external noise. This check is necessary to prevent misidentification of noise
sources.
(3) Noise prevention should be performed by eliminating noise sources in the descending order of loudness.

INSTALLATION SERVICE POINT
ACOMPRESSOR INSTALLATION
If a new compressor is installed, first adjust the amount of
oil according to the procedures described below, and then
install the compressor.
1. Measure the amount (X m
) of oil within the removed
compressor.
2. Drain (from the new compressor) the amount of oil
calculated according to the following formula, and then
install the new compressor.
New compressor oil amount
120 to 140 m
– X m
= Y m

NOTE
(1)“120 to 140 ml” is the amount of oil filled in a new
compressor.
(2) Y m
indicates the amount of oil in the refrigerant
line, the condenser, the cooling unit etc.
INSPECTION
REFRIGERANT-TEMPERATURE SWITCH SIMPLE
CHECK
When the A/C is off, check that there is continuity between
the refrigerant-temperature switch terminals. If no, replace
the compressor assembly.
COMPRESSOR MAGNETIC CLUTCH OPERATION
INSPECTION
Connect the battery (+) terminal to the compressor side
terminal, and earth the battery (–) terminal to the body of
the compressor. The condition is normal if the sound of the
magnetic clutch (click) can be heard.AView A
