/ 6.
STEERING LOCK BRACKET / 5. SPECIAL BOLT
(1) When installing the steering lock cylinder and steering
lock bracket to the column tube, temporarily install the
steering lock in alignment with the column boss.
(2) After checking that the lock works properly, tighten the
special bolts until the head twists off.
CautionThe steering lock bracket and bolts must be re-
placed with new ones when the steering lock
cylinder is installed.3. INSTALLATION OF BEARING
(1) Fill the inside of the bearing with multipurpose grease.
(2) Install the bearings to the shaft on the joint assembly.
(3) Wrap vinyl tape approximately one and one-half times
around the concave circumferences of the bearings,
and then press fit the bearings into the cover assembly.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS) - ~~~-~~~~~a~~g~~~s 52B-552. Repair Procedure
(1) If air bag deployed in the collision, remove the deployed
air bag module. (Refer to
P.52B-62.)(2) Check the SRS components using the table shown
below.
If the SRS components are showing any visible damage
such as dents, cracks, or deformation, replace them
with new ones.
Refer to appropriate INDIVIDUAL COMPONENT SER-
VICE, P.52B-56.
(3) Conduct self-diagnosis using Multi-use Tester to ensure
entire SRS operates properly except open circuit of air
bag module (22. SQUIB TRBL 2).
(4) Install new air bag module. (Refer to
P.52B-62.)
SRS ComponentsInspection(when air bag deploys in collision)Inspection (when air bag does not deploy
in low-speed collision)
Front impact sensors
Replace front impact sensors.(Refer to P.52B-56.)(1)Check front upper frame lower and sensor
brackets for deformities or rust.
(2)Check sensor cases for dents, cracks deformi-ties or rust.
(3)Check sensor harnesses for binds, connectors
for damage, and terminals for deformities.
SRS diagnosis unitSDU)Replace SRS diagnosis unit.(Refer to P.52B-59.)(1)Check SDU case and brackets for dents, cracksor deformities.(2)Check connectors and lock lever for damage,and terminals for deformities.
jir bag moduleReplace air bag module.(Refer to P.52B-62.)(1)Check pad cover for dents, cracks or deformi-ties.
(2)Remove air bag module from steering wheel.
Check hooks and connector for damage, termi-
nals for deformities, and harness for binds.
(Refer to P.52B-62.)(3)Check air bag inflator case for dents, cracks or
deformities.
(4)Install air bag module to steering wheel to.checlfit or alignment with the wheel.

INSPECTIONAIR BAG MODULE
Caution
Never attempt to measure the circuit resistance of the airbag module (squib) even if you are using the specified
tester. If the circuit resistance is measured with a tester,
accidental air bag deployment will result in serious person-al injury.
(1) Check pad cover for dents, cracks or deformities.
(2) Check the air bag module for denting, cracking or deforma-
tion.
(3) Check hooks and connectors for damage, terminals for
deformities, and harness for binds.
(4) Check air bag inflator case for dents, cracks or deformities.
TSB Revision(5) Install the air bag module to steering wheel to check fit or
alignment with the wheel.
CautionIf a dent, crack or other deformation is discovered,
replace the air bag module with a new one.
Dispose of the old one according to the specified
procedure. (Refer to
P52B-69 to P.52B-72.)
