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.)

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-32
AIR BAG MODULE DISPOSAL PROCEDURES
Before disposing of an air bag or a vehicle which
is equipped with it, the procedures below are to
be followed to deploy them.
UNDEPLOYED AIR BAG MODULE DISPOSAL
PROCEDURES
Caution
1. If the vehicle is to be scrapped or otherwise disposed
of, deploy the air bags inside the vehicle. If the vehicle
will continue to be used and only the air bag modules
are to be disposed of, deploy the air bags outside
the vehicle.
2. Since a large amount of smoke is produced when
the air bag is deployed, avoid residential areas
whenever possible.
3. Since there is loud noise when the air bags are
deployed, avoid residential areas whenever possible.
If anyone is nearby, give warning of the impending
noise.
4. Suitable ear protection should be worn by personnel
performing these procedures or by people in the
immediate area.
DEPLOYMENT INSIDE THE VEHICLE
(when disposing of a vehicle)
1. Move the vehicle to an isolated spot.
2. 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-3.)

Inspection Procedure 3
While key hole illumination lamp is illuminated, ignition
key is turned to the ON position but key hole illumination
lamp does not switch off. (However, it switch off after 15
seconds.)
Probable cause
While the key reminder warning buzzer is sounding, the
ignition key is turned to the ON position but the sound
dose not stop. (However, it stops when the driver’s side
door is closed.)
The cause is probably a malfunction of the ignition switch input circuit, ETACS-ECU
or buzzer ECU. Furthermore, if there is a malfunction of a multipurpose fuse, the
cause may also be a short circuit in a harness.
