CABLE FROM THE BATTERYTurn the ignition key to the “LOCK” position, disconnect
the negative battery cable and tape the terminal.
Caution
Wait at least 30 seconds after disconnecting the battery
cable before doing any further work. The SRS system is
designed to retain enough voltage to deploy the air bagfor a short time even after the battery has been
disconnected, so serious injury may result from unin-
tended air bag deployment if work is done on the SRSsystem immediately after the battery cable is discon-
nected.2. REMOVAL OF AIR BAG MODULE
(1) Remove the air bag module mounting nut using a
socket wrench from the back side.
(2) When disconnecting the connector of the clock spring
from the air bag module, press the air bag’s lock toward
the outer side to spread it open. Use a screwdriver, as
shown in the figure at the left, to pry so as to remove
the connector gently.
CautionWhen disconnecting the air bag module-clock
spring connector, take care not to apply excessiveforce to it.
(3) The removed air bag module should be stored in a
clean, dry place with the pad cover face up.
8. REMOVAL OF STEERING WHEEL
Remove the steering wheel by using a steering wheel
puller.
CautionDo not hammer on the steering wheel. Doing so may
damage the collapsible column mechanism.
9. DISCONNECTION OF THE SRS DIAGNOSIS UNIT AND
CLOCK SPRING CONNECTION

UNDEPLOYED AIR BAG MODULE DISPOSAL
CautionIf the vehicle is to be scrapped, junked, or otherwise
disposed of, deploy the air bag inside the vehicle.
If the vehicle will continue to be operated and only the air
bag module is to be disposed of, deploy the air bag outside
the vehicle.
1. DEPLOYMENT INSIDE THE VEHICLE(when vehicle will no longer be driven)
(1) Open all windows and doors of the vehicle. Move the
vehicle to an isolated spot.
(2) Disconnect the negative
(4 and positive (i-1 battery
cables from the battery terminals, and then remove the
battery from the vehicle.
CautionWait at least 30 seconds after disconnecting the
battery cables before doing any further work. The
SRS system is designed to retain enough voltage todeploy the air bag for a short time even after the
battery has been disconnected, so serious injury
may result from unintended air bag deployment if
work is done on the SRS system immediately after
the battery cables are disconnected.

(removed from the vehicle) to deploy the air bag.
Caution
1.Before deploying the air bag in this manner, first
check to be sure that there is no one in or nearthe vehicle. Wear safety glasses.
2. The inflator will be quite hot immediately fol-
lowing 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 fromair bag deployment.
See Deployed Air Bag Module Disposal Proce-
dures
(P.52B-72) 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 regional Tech Line at 1-800-446-
6064 for instructions.
DEPLOYMENT OUTSIDE THE VEHICLE(1) Disconnect the negative
(4 and positive (+) battery
cables from the battery terminals, and then remove the
battery from the vehicle.
CautionWait at least 30 seconds after disconnecting the
battery cables before doing any further work. The
SRS system is designed to retain enough voltage todeploy the air bag for a short time even after the
battery has been disconnected, so serious injury
may result from unintended air bag deployment if
work is done on the SRS system immediately afterthe battery cables are disconnected.
(2) Remove the air bag module for the vehicle. (Refer toP.528-62.)
CautionThe air bag module should be stored on a flat
surface and placed so that the pad cover face up. Donot place anything on top of it.
(3) Connect two wires each six meters (20 feet) long, to
the two leads of SRS AIR BAG ADAPTER HARNESS B,
and cover the connections with insulation tape. The
other ends of the two wires should be connected to
each other (short-circuited), to prevent sudden unex-
pected deployment of the air bag.

a flat, spacious area at least 6 meters (20 feet) away
from any people, equipment or other objects. Connect
SRS AIR BAG ADAPTER HARNESS B to the air bag
mdmodule connector on the module’s underside.
(5) At a location as far away from the air bag module as
possible, and from a shielded position, if possible,
disconnect the two connected wires from each other
and connect them to the two terminals of the battery
(removed from the vehicle) to deploy the air bag.
Caution1. Do not perform deployment outside, if a strong
wind is blowing, and if there is even a slight
breeze, the air bag module should be placed anddeployed downwind from the battery.
2. Before deployment, check carefully to be sure
that no one is nearby, because deployment will
cause the air bag module to jump upward about
1.5 to 3 meters (about 5 to 10 feet) into the air.3. The inflator will be quite hot immediately fol-
lowing deployment, so wait at least 30 minutes
to allow it to cool before attempting to handle it.
Although not poisonous, do not inhale gas fromair bag deployment. See Deployed Air Bag
Module Disposal Procedures (as shown below)for post-deployment handling instructions.
4. If the air bag module fails to deploy when the

TEST PROCEDURESSIGHT GLASS REFRIGERANT LEVEL TEST
The sight glass is a refrigerant level indicator. To check the
refrigerant level, clean the sight glass and start the vehicle
engine. Push the air conditioner button to operate the com-
pressor, place the blower switch to high and move the
temperature control lever to MAX. COOL. After operating for a
few minutes in this manner, check the sight glass.
(I) If the sight glass is clear, the magnetic clutch is engaged,
the compressor discharge line is warm and the compressor
inlet line is cool; the system has a full charge.
(2) If the sight glass is clear, the magnetic clutch is engaged
and there is no significant temperature difference between
compressor inlet and discharge lines; the system has lost
some refrigerant.
(3) If the sight glass shows foam or bubbles, the system could
be low on charge. The system has to be charged with some
refrigerant.
MAGNETIC CLUTCH(1) Disconnect the wiring to the magnetic clutch.
(2) Connect battery (+) voltage directly to the wiring for the
magnetic clutch.
(3) If the magnetic clutch is normal, there will be a “click”. If
the pulley and armature do not make contact (“click”), there
is a malfunction.
