Precautions For Refrigerant System ServiceINFOID:0000000012430712
GENERAL REFRIGERANT PRECAUTION
WARNING:
• Do not breathe A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat.
Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. Venti-
late work area before resuming service if accidental system discharge occurs. Additional health and
safety information may be obtained fr om refrigerant and oil manufacturers.
• Do not release refrigerant into the air. Use ap proved recovery/recycling recharging equipment to
capture the refrigerant each time an air conditioning system is discharged.
• Wear always eye and hand protection (goggles and gloves) when working with any refrigerant or air
conditioning system.
• Do not store or heat refrigerant containers above 52 °C (126° F).
• Do not heat a refrigerant container with an open fl ame. Place the bottom of the container in a pail of
warm water if container warming is required.
• Do not intentionally drop, puncture, or incinerate refrigerant containers.
• Keep refrigerant away from open flames. Pois onous gas is produced if refrigerant burns.
• Refrigerant displaces oxygen, therefore be certain to work in well ventilated areas to prevent suffo- cation.
• Do not pressure test or leakage test HFC-134a (R- 134a) service equipment and/or vehicle air condi-
tioning systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a)
have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause
injury or property damage. Additional health and safety information may be obtained from refriger-
ant manufacturers.
WORKING WITH HFC-134a (R-134a)
CAUTION:
• CFC-12 (R-12) refrigerant and HFC-134a (R-134a) re frigerant are not compatible. These refrigerants
must never be mixed, even in the smallest amount s. Compressor malfunction is likely occur if the
refrigerants are mixed.
• Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components.
Compressor malfunction is likely to occur if oil other than that specified is used.
• The specified HFC-134a (R-134a) oi l rapidly absorbs moisture from the atmosphere. The following
handling precautions must be observed:
- Cap (seal) immediately the component to minimize the entry of mo isture from the atmosphere when
removing refrigerant components from a vehicle.
- Do not remove the caps (unseal) unti l just before connecting the components when installing refrig-
erant components to a vehicle. Connect all refr igerant loop components as quickly as possible to
minimize the entry of moisture into system.
- Use only the specified oil from a sealed container. Reseal immediately containers of oil. Oil becomes
moisture saturated and should no t be used without proper sealing.
- Do not allow oil (A/C System Oil Type: DH-PR) to come in contact with styrene foam parts. Damage
may result.
REFRIGERANT CONNECTION
A new type refrigerant connection has been introduced to al l refrigerant lines except the following location.
• Expansion valve to evaporator
• Refrigerant pressure sensor to liquid tank
WARNING:
Check that all refrigerant is disch arged into the recycling equipment and the pressure in the system is
less than atmospheric pressure. Then gradually loo sen the discharge side hose fitting and remove it.
CAUTION:
Observe the following when replacing or cleaning refrigerant cycle components.

• When the compressor is removed, store it in th e same way as it is when mounted on the vehicle.
Failure to do so will cause oil to enter the low-pressure chamber.
• Use always a torque wrench and a b ack-up wrench when connecting tubes.
• Plug immediately all openings to prevent entry of dust and mois ture after disconnecting tubes.
• Connect the pipes at the final stag e of the operation when installing an air conditioner in the vehicle.
Do not remove the seal caps of pipes and other comp onents until just before required for connec-
tion.
• Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.
• Remove thoroughly moisture from the refriger ation system before charging the refrigerant.
• Replace always used O-rings.
• Apply oil to the O-rings shown in illustrations wh en connecting tubes. Be careful not to apply oil to
threaded portion.
• O-ring must be closely attached to the groove portion of tube.
• Be careful not to damage O-ring and tube when replacing the O-ring.
• Connect tube until a click can be heard. Then tighten the nut or bolt by hand. Check that the O-ring is
installed to tube correctly.
• Perform leak test and make sure there are no leaks from connections after connecting lines. Discon-
nect that line and replace the O-ring when the refrigerant leak point is found. Then tighten connec-
tions of seal seat to the specified torque.
COMPRESSOR
CAUTION:
• Plug all openings to prevent moisture and foreign matter from entering.
• When the compressor is removed, store it in the same way as it is when mounted on the vehicle.
• Follow “MAINTENANCE OF OIL LEVEL” exactly when replacing or repairing compressor. Refer to HA-22, "
Description".
• Keep friction surfaces between clutch and pulley clean . Wipe them off by using a clean waste cloth
moistened with solvent if the su rfaces are contaminated with oil.
• Turn the compressor shaft by hand more than fi ve turns in both directions after compressor service
operation. This equally distribut es oil inside the compressor. Let the engine idle and operate the
compressor for one hour after the compressor is installed.
• After replacing the compressor magnet clutch, appl y voltage to the new clutch to check for normal
operation.
LEAK DETECTION DYE
CAUTION:
• The A/C system contains a fluorescent leak detect ion dye used for locating refrigerant leaks. An
ultraviolet (UV) lamp is required to il luminate the dye when inspecting for leaks.
• Always wear fluorescence enhancing UV safety goggles to protect eyes and enhance the visibility of
the fluorescent dye. Name : A/C System Oil Type: DH-PR

< PRECAUTION >[MANUAL AIR CONDITIONING]
PRECAUTIONS
• The fluorescent leak detection dye is not a replacem
ent for an electronic leak detector. The fluores-
cent leak detection dye should be u sed in conjunction with an electronic leak detector to pin-point
refrigerant leaks.
• Read and follow all manufacture’s operating inst ructions and precautions prior to performing the
work for the purpose of safet y and customer’s satisfaction.
• A compressor shaft seal should not necessarily be repaired becau se of dye seepage. The compres-
sor shaft seal should only be repaired after conf irming the leak with an electronic leak detector.
• Always remove any remaining dye from the leak area after repairs are completed to avoid a misdiag-
nosis during a future service.
• Do not allow dye to come into contact with painted body panels or interior components. Clean imme- diately with the approved dye cl eaner if dye is spilled. Fluorescent dye left on a surface for an
extended period of time cannot be removed.
• Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.).
• Do not use more than one refrigerant dye bottle [1/4 ounce (7.4 cc)] per A/C system.
• Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use
HFC-134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system, or CFC-12 (R-12) leak detection
dye in HFC-134a (R-134a) A/C system, or A/C system damage may result.
• The fluorescent properties of the dye remains fo r three or more years unless a compressor malfunc-
tion occurs.
NOTE: Identification
• Vehicles with factory installed fluorescent dye have a green label.
• Vehicles without factory installed fluorescent dye have a blue label.
Service EquipmentINFOID:0000000012430713
RECOVERY/RECYCLING RECHARGING EQUIPMENT
Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance. Do not
introduce any refrigerant other than that specified into the machine.
ELECTRICAL LEAK DETECTOR
Be certain to follow the manufacturer’s instruct ions for tester operation and tester maintenance.
VACUUM PUMP
The oil contained inside the vacuum pump is not compatible with the
specified oil for HFC-134a (R-134a) A/C systems. The vent side of
the vacuum pump is exposed to atmospheric pressure. Vacuum
pump oil may migrate out of the pump into the service hose. This is
possible when the pump is switc hed OFF after evacuation (vacuum-
ing) and hose is connected to it.
To prevent this migration, use a manual valve placed near the hose-
to-pump connection, as per the following.
• Vacuum pumps usually have a manual isolator valve as part of the pump. Close this valve to isolat e the service hose from the pump.
• Use a hose equipped with a manual shut-off valve near the pump
end for pumps without an isolator. Close the valve to isolate the
hose from the pump.
• Disconnect the hose from the pump if the hose has an automatic
shut-off valve. As long as the hose is connected, the valve is open
and lubricating oil may migrate.
Some one-way valves open when vacuum is applied and close
under no vacuum condition. Such valves may restrict the pump’s
ability to pull a deep vacuum and are not recommended.

Be certain that the gauge face indicates HFC-134a or R-134a. Be
sure the gauge set has 1/2 ″-16 ACME threaded connections for ser-
vice hoses. Confirm the set has been used only with refrigerant
HFC-134a (R-134a) and specified oils.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe) . All hoses must be equipped with
positive shut-off devices (either manual or automatic) near the end of
the hoses opposite to the manifold gauge.
SERVICE COUPLERS
Do not attempt to connect HFC-134a (R-134a) service couplers to
the CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers
do not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied oils have been used with the scale. The hose fitting must be 1/
2 ″-16 ACME if the scale controls refrigerant flow electronically.
CHARGING CYLINDER
Using a charging cylinder is not re commended. Refrigerant may be vented into air from cylinder’s top valve
when filling the cylinder with refrigerant. Also, the accura cy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.

1. ECM The ECM sends a compressor ON request to the IPDM E/R based on the status of engine
operation and load as well as refrigerant pressure information. If all the conditions are met for
A/C operation, the ECM transmits the compressor ON request to the IPDM E/R.
2. IPDM E/R A/C relay is integrated in IPDM E/R. IPDM
E/R operates A/C relay when receiving A/C com-
pressor request signal from ECM via CAN communication line.
3. A/C compressor Vaporized refrigerant is drawn into the A/C compressor from the evaporator, where it is com-
pressed to a high pressure, high temperature vapor. The hot, compressed vapor is then dis-
charged to the condenser.
4. Refrigerant pressure sensor Refer to EC-27, "
Refrigerant Pressure Sensor".

No. Component Description
1. BCM The BCM receives the fan ON and A/C ON signals from the front air control and sends a com-
pressor ON request to the ECM.
2. Fuse Block (J/B) Located in the passenger compartment, behind the left lower IP, the Fuse Block (J/B) con-
tains the front blower motor relay and several fuses required for the air conditioner control
system.
3. Blower relay The blower relay controls the flow of current to fuse 20, 21 and 22 in the Fuse Block (J/B).
The relay is connected directly to ground, and is energized when the ignition switch is in the
ON or START position.
4. Front blower motor The front blower motor varies the speed at which the air flows through the ventilation system.
5. Front blower motor resistor Ground for the blower is supplied through blower resistor and the blower speed switch. As
the switch is moved from position 1 through 4, more current is allowed to flow through the
motor, for a higher speed. This is because less resistors are in the path as the switch is
moved to a higher position. When the switch is on the highest position, all resistors are by-
passed.
6. Thermo control amp. Thermo control amp. is composed of thermistor and amplifier. When the A/C switch signal is
received from the front air control, the thermo control amp. transmits the A/C ON signal to the
BCM according to evaporator fin temperature. When the thermistor detecting temperature of
the air that passes through evaporator is extremely low, the thermo control amp. sends the
A/C OFF signal to BCM, and stops the compressor.
7. Front air control The front air control controls the operation of the A/C and heating system.
