KTOTAL PINION TORQUE ADJUSTMENT
1. Position the rack at its centre. Tighten the rack support
cover to 15 Nm.
2. In neutral position, rotate the pinion shaft clockwise one
turn/4 – 6 seconds with the special tool. Return the rack
support cover 30 – 60 and adjust torque to the standard

INSPECTION
RACK CHECK

Check the rack tooth surfaces for damage or wear.

Check the oil seal contact surfaces for uneven wear.

Check the rack for bends.
PINION AND VALVE ASSEMBLY CHECK

Check the pinion gear tooth surfaces for damage or wear.

Check for worn or defective seal ring.
BEARING CHECK

Check for roughness or abnormal noise during bearing
operation.

Check the bearing for play.

Check the needle roller bearing for roller slip-off.
OTHER CHECK

Check the cylinder inner surface of the rack housing for
damage.

Check the boots for damage, cracking or deterioration.

Check the rack support for uneven wear or dents.

Check the rack bushing for uneven wear or damage.

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.
