Disposal Procedures52B-72
Front passenger’s air bag module
(1) Remove the front passenger’s air bag module from
the vehicle. (Refer to P.52B-52.)
Caution
Once disconnected, both electrodes of the front
passenger’s air bag module connector short
automatically to prevent accidental deployment
caused by static etc. Still, in consideration of the
accidental deployment, store the air bag module
on flat place with deployment surface facing up.
Also, do not put anything on it.
(2) Connect deployment harness 6 m or longer with the
SRS air bag adapter harness respectively. Insulate
the connection with tape.
Also, connect the other ends of the deployment
harness each other to short, thereby preventing the
front passenger’s air bag from accidental deployment
caused by static etc.
(3) Route the SRS air bag adapter harness with the
deployment harnesses beneath an old tyre and wheel
assembly. Then, connect the harnesses to the front
passenger’s air bag module.
(4) Route a thick wire through the holes in the front
passenger’s air bag module bracket. With the
deployment surface facing up, secure the front
passenger’s air bag module to the old tyre and wheel
assembly.
Caution
1) The adapter harness below the wheel should
be loose. If it is too tight, the reaction when the
air bag deploys could damage the adapter
harness.
2) Place the connector of the SRS air bag adapter
harness so that it is not clamped by the tyre at
deployment.
(5) Put three old tyres without wheels on the tyre secured
to the front passenger’s air bag module. Secure all
the tyres with ropes (4 locations).
NOTE
The tyres must be bound because the passenger’s
air bag inflates more than the driver’s air bag.

(6) Disconnect the deployment harnesses as far from
the front passenger’s air bag module as possible and
connect the harnesses to the battery removed from
the vehicle.
Caution
1) Before the deployment, see that no one is near
the front passenger’s air bag module.
2) The deployment makes the inflator of the front
passenger’s air bag very hot. Before handling
the inflator, wait more than 30 minutes for
cooling.
3) If the front passenger’s air bag module fails to
deploy although the procedure is respected,
do not go near the module. Contact your local
distributor.
(7) Discard the deployed air bag module as specified
in Deployed Air Bag Module Disposal Procedures.
(Refer to P.52B-75.)
Seat belt pre-tensioner
(1) Remove the seat belt with pre-tensioner from the
vehicle. (Refer to P.52B-61.)
Caution
Once disconnected, both electrodes of the seat
belt pre-tensioner are short-circuited
automatically to prevent accidental deployment
caused by static etc. Still, in consideration of the
accidental deployment, store the air bag module
on flat place with deployment surface facing up.
Also, do not put anything on it.
(2) Connect deployment harness 6 m or longer with the
SRS air bag adapter harness respectively. Insulate
the connection with tape.
Moreover, the ends of the operation harness should
be connected (short-circuited) to each other. Thus,
it prevents the seat belt pre-tensioner from accidental
deployment caused by static and etc.

(4) Connect the seat belt pre-tensioner connector to the
the SRS air bag adapter harness with the operation
harness attached.
(5) Pull out the seat belt outside the tyre.
Caution
Place the connector of the SRS air bag adapter
harness so that it is not clamped by the tyres at
deployment.
(6) Place an old tyre (without a wheel) on the tyre, which
the seat belt with pre-tensioner is secured on.
(7) Disconnect the deployment harness as far fromthe
seat belt pre-tensioner as possible and connect the
both terminals of the battery removed from the vehicle.
Then deploy.
Caution
1) Before the deployment, see that no one is near
the seat belt pre-tensioner.
2) Before handling the insulator, wait for a while
for cooling.
3) If the seat belt pre-tensioner fails to operate
although the procedure is respected, do not go
near the seat belt pre-tensioner. Contact your

the inflator.
2. Do not apply any water or oil onto the deployed air bag
module or the operated seat belt pre-tensioner.
3. Wear gloves and protective glasses before handing the
deployed air bag module or the operated seat belt
pre-tensioner since materials on those parts may cause
irritation to eyes or skin.
Caution
If after following these precautions, any material does
get into the eyes or on the skin, immediately rinse the
affected area with a large amount of clean water.
If any irritation develops, seek medical attention.
4. Discard the air bag module and the seat belt with
pre-tensioner after placing them into a strong vinyl bag
for sealing.
5. Be sure to always wash your hands after completing this
operation.

DUAL PRESSURE SWITCH CHECK
1. Remove the dual pressure switch connector and connect
the high/low pressure side terminals located on the
harness side as shown in the illustration.
2. Install a gauge manifold to the high
-pressure side service
valve of the refrigerant line. (Refer to 55-42.)
3. When the high/low pressure sides of the dual pressure
switch are at operation pressure (ON) and there is
continuity between the respective terminals, then the
condition is normal. If there is no continuity, replace the
switch.

REFRIGERANT LEAK REPAIR
LOST CHARGE
If the system has lost all charge due to a leak:
1. Evacuate the system. (See procedure.)
2. Charge the system with approximately one
pound of refrigerant.
3. Check for leaks.
4. Discharge the system.
5. Repair leaks.
6. Replace receiver drier.
Caution
Replacement filter-drier units must be
sealed while in storage. The drier used in
these units will saturate water quickly upon
exposure to the atmosphere. When
installing a drier, have all tools and supplies
ready for quick reassembly to avoid keeping
the system open any longer than necessary.
7. Evacuate and charge system.
LOW CHARGE
If the system has not lost all of its refrigerant charge;
locate and repair all leaks. If it is necessary to
increase the system pressure to find the leak
(because of an especially low charge) add
refrigerant. If it is possible to repair the leak without
discharging the refrigerant system, use the
procedure for correcting low refrigerant level.HANDLING TUBING AND FITTINGS
Kinks in the refrigerant tubing or sharp bends in
the refrigerant hose lines will greatly reduce the
capacity of the entire system. High pressures are
produced in the system when it is operating.
Extreme care must be exercised to make sure that
all connections are pressure tight. Dirt and moisture
can enter the system when it is opened for repair
or replacement of lines or components. The
following precautions must be observed. The
system must be completely discharged before
opening any fitting of connection in the refrigeration
system. Open fittings with caution even after the
system has been discharged. If any pressure is
noticed as a fitting is loosened, allow trapped
pressure to bleed off very slowly.
Never attempt to rebend formed lines to fit. Use
the correct line for the installation you are servicing.
A good rule for the flexible hose lines is keep the
radius of all bends at least 10 times the diameter
of the hose.
Sharper bends will reduce the flow of refrigerant.
The flexible hose lines should be routed so that
they are at least 80 mm from the exhaust manifold.
It is good practice to inspect all flexible hose lines
at least once a year to make sure they are in good
condition and properly routed.
Unified plumbing connections with O-rings, these
O-rings are not reusable.
COMPRESSOR NOISE
You must first know the conditions when the noise
occurs. These conditions are: weather, vehicle
speed, in gear or neutral, engine temperature or
any other special conditions.
Noises that develop during A/C operation can often
be misleading. For example: what sounds like a
failed front bearing or connecting rod, may be
caused by loose bolts, nuts, mounting brackets,
or a loose clutch assembly. Verify accessory drive
belt tension (power steering or alternator).
Improper accessory drive belt tension can cause
a misleading noise when the compressor is
engaged and little or no noise when the compressor
is disengaged.
Drive belts are speed-sensitive. That is, at different
engine speeds, and depending upon belt tension,
belts can develop unusual noises that are often
mistaken for mechanical problems within the
compressor.ADJUSTMENT
1. Select a quiet area for testing. Duplicate
conditions as much as possible. Switch
compressor on and off several times to clearly
identify compressor noise. To duplicate high
ambient conditions (high head pressure),
restrict air flow through condenser. Install
manifold gauge set to make sure discharge
pressure doesn’t exceed 2,070 kPa.
2. Tighten all compressor mounting bolts, clutch
mounting bolt, and compressor drive belt.
Check to assure clutch coil is tight (no rotation
or wobble).
3. Check refrigerant hoses for rubbing or
interference that can cause unusual noises.
4. Check refrigerant charge. (See “Charging
System”.)
5. Recheck compressor noise as in Step 1.
6. If noise still exists, loosen compressor mounting
bolts and retorque. Repeat Step 1.
7. If noise continues, replace compressor and
repeat Step 1.
