Hoist vehicle.
Inspect each boot for tear. A torn boot allows entry of
dust and water which can cause wear to steering rack
and pinion to produce noise as well as rust to result in
malfunction of steering system.
Even if boot tear is small, replace with new one.
Also, check each boot for dent. If there is a dent, keep
boot in most compressed state for some seconds to
correct dent.
Boots should be visually inspected for any damage, dent
and tear during every periodical inspection at specified
intervals and whenever vehicle is hoisted for any other
purpose.

Check A/C System for Refrigerant Leaks
Whenever a refrigerant leak is suspected in the system
or any service operation has been performed which may
result in malfunction of lines and connections, it is
advisable to check for leaks.
Common sense should be used during refrigerant leak
test, since the need and extent of any such test will, in
general, depend upon the nature of a complaint and the
type of a service performed on the system.
Liquid leak detector
WARNING!
• To prevent explosions and fires, make sure
that there are no flammables in the vicinity.
• When the refrigerant exposed to fire, it
turns into a poisonous gas (phosgene). Do
not inhale this gas.

There is a number of fittings and places throughout the
A/C system where a liquid leak detector solution may be
used to pinpoint refrigerant leaks.
By merely applying the solution to the area in question
with a swab, such as attached to the cap of a vial,
bubbles will form within seconds if there is a leak.
For confined areas, such as sections of the evaporator
and condenser, an electronic (refrigerant) leak detector
is more practical for determining leaks.

Side Curtain-Air Bag (Inflator) Module Removal
and Installation
S6RW0D8206022
WARNING!
• Never attempt to disassemble or repair the
side curtain-air bag (inflator) module. If any
abnormality is found, be sure to replace it
with new one as an assembly.
• Be sure to read “Precautions on Service
and Diagnosis of Air Bag System”,
“Precautions on Handling and Storage of
Air Bag System Components” and
“Precautions on Disposal of Air Bag and
Seat Belt Pretensioner” before starting to
work and observe every precaution during
work. Neglecting them may result in
personal injury or undeployment of the air
bag when necessary.

Removal
1) Disable air bag system. Refer to “Disabling Air Bag
System”.
2) Remove head lining referring to “Head Lining
Removal and Installation in Section 9H”.
3) Disconnect side curtain-air bag (inflator) module
connector (1) as shown in figure.
a) Unlock lock button (2).
b) With lock button unlocked, disconnect connector.
4) Remove side curtain-air bag (inflator) module fixing

WARNING!
• When carrying a live air bag (inflator)
module, make sure the bag opening is
pointed away from you.
Never carry air bag (inflator) module by
wires or connector on the side of the
module. In case of an accidental
deployment, the bag will then deploy with
minimal chance of injury.
• As the live curtain air bag (inflator) module
must be kept with its bag facing up while
being stored or left standing. This is
necessary so that a free space is provided
to allow the air bag to expand in the
unlikely event of accidental deployment.
