HFC-134a (R-134a) Service Tool and Equipment Never mix HFC-134a (R-134a) refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/
or its lubricant.
 Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/
lubricant.
 Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
 Never use adapters that convert one size fitting to another: refrigerant/lubricant contamination occurs and
compressor malfunction may result.

FLUORESCENT LEAK DETECTOR
FLUORESCENT LEAK DETECTOR
InspectionINFOID:0000000003795981
CHECKING SYSTEM FOR LEAKAGES USING THE FLUORESCENT LEAK DETECTOR
1. Check A/C system for leakages using the UV lamp and safety goggles (SST: J-42220) in a low sunlight
area (area without windows preferable). Illuminate all components, fittings and lines. The dye appears as
a bright green/yellow area at the point of leakage. Fluorescent dye observed at the evaporator drain open-
ing indicates an evaporator core assembly (tubes, core or expansion valve) leakage.
2. Use an adjustable mirror or wipe the area with a clean shop rag or cloth, with the UV lamp for dye residue
if the suspected area is difficult to see.
3. Remove any residual dye using dye cleaner (SST: J-43872) to prevent future misdiagnosis after the leak-
age is repaired.
4. Perform a system performance check and verify the leakage repair with an approved electrical leak detec-
tor.
NOTE:
Other gases in the work area or substances on the A/C components, for example, anti-freeze, windshield
washer fluid, solvents and lubricants, may falsely trigger the leak detector. Make sure the surfaces to be
checked are clean.
Clean with a dry cloth or blow off with shop air.
Do not allow the sensor tip of the detector to contact with any substance. This may also cause false readings
and may damage the detector.
DYE INJECTION
(This procedure is only necessary when recharging the system or when the compressor has seized and was
replaced.)
1. Check A/C system static (at rest) pressure. Pressure must be at least 345 kPa (3.45 bar, 3.52 kg/cm
2, 50
psi).
2. Pour one bottle (1/4 ounce / 7.4 cc) of the A/C refrigerant dye into the injector tool (SST: J-41459).
3. Connect the injector tool to the A/C low-pressure side service valve.
4. Start the engine. Then switch A/C ON.
5. Inject one bottle (1/4 ounce / 7.4 cc) of fluorescent dye through the low-pressure service valve using dye
injector tool (SST: J-41459) (refer to the manufacture’s operating instructions) when the A/C operating
(compressor running).
6. Disconnect the injector tool from the service valve with the engine still running.
CAUTION:
Be careful when replacing the A/C system or a component, pour the dye directly into the open sys-
tem connection and proceed with the service procedures.
7. Operate the A/C system for a minimum of 20 minutes to mix the dye with the system oil. Depending on the
leakage size, operating conditions and location of the leakage, it may take from minutes to days for the
dye to penetrate a leakage and become visible.
8. Attach a blue label if necessary.

4.CHECK INTAKE AIR
1. Press the REC switch. REC indicator is turned ON.
2. Press the FRE switch. FRE indicator is turned ON.
3. Listen for the intake door position change. (Slight change of blower sound can be heard.)
NOTE:
Confirm that the compressor clutch is engaged (sound or visual inspection) and the intake door position is at
the FRE when the DEF is selected.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Intake door system malfunction: HAC-64, "
Diagnosis Procedure".
5.CHECK A/C SWITCH
1. Press the A/C switch.
2. The A/C switch indicator is turned ON.
Confirm that the compressor clutch engages (sound or visual inspection).
Is the inspection result normal?
YES >> GO TO 6.
NO >> Magnet clutch system malfunction: HAC-72, "
Diagnosis Procedure".
6.CHECK WITH TEMPERATURE SETTING LOWERED
1. Operate the compressor.
2. Operate the temperature control switch (driver side) and lower the temperature setting to 18°C (60°F).
3. Check that the cool air blows from the outlets.
Is the inspection result normal?

ture, and temperature setting).
Is the inspection result normal?
YES >> GO TO 10.
NO >> Refer to HAC-87, "
Diagnosis Chart By Symptom" and perform the appropriate diagnosis.

B2630, B2631 SUNLOAD SENSOR
DescriptionINFOID:0000000003846340
COMPONENT DESCRIPTION
Sunload Sensor
 The sunload sensor (1) is located on the driver’s side speaker
grille.
 It detects sunload entering through windshield by means of a
photo diode. The sensor converts the sunload into a current value
which is then input into the A/C auto amp.
Sunload Sensor Circuit
SUNLOAD INPUT PROCESS
The A/C auto amp. also equips a processing circuit which averages the variations in detected sunload over a
period of time. This prevents drastic swings in the air temperature control system operation due to small or
quick variations in detected sunload.
For example, consider driving along a road bordered by an occasional group of large trees. The sunload
detected by the sunload sensor varies whenever the trees obstruct the sunlight. The processing circuit aver-
ages the detected sunload over a period of time, so that the (insignificant) effect of the trees momentarily
obstructing the sunlight does not cause any change in the air temperature control system operation. On the
other hand, shortly after entering a long tunnel, the system recognizes the change in sunload, and the system
reacts accordingly.
