INTERIOR TEMPERATURE SENSOR CHECK
When the resistance between the sensor terminals is mea-
sured under two or more temperature conditions, the resis-
tance should approximately satisfy the illustrated values.
NOTE:
The temperature conditions when checking should not
exceed the range shown in the diagram.
.
PHOTO SENSOR CHECK
1. Connect diagnostic tool , and check the data list of the
photo sensor. (Refer to P.55-133)
2. Check that the displayed value changes when you cover
the photo sensor with your hands.

AMBIENT AIR TEMPERATURE SENSOR CHECK
The ambient air temperature sensor should be checked
without removing it from bumper. If the sensor is removed,
damage will occur to clip rendering it unserviceable.
Measure the resistance between the sensor terminals under at
least two temperatures. The resistance values should meet the
values shown.
NOTE: The temperature should be within the shown range.

REMOVAL SERVICE POINTS
.
<<A>> FLEXIBLE SUCTION HOSE AND FLEXIBLE
DISCHARGE HOSE DISCONNECTION
As the compressor oil and receiver are highly moisture
absorbent, use a non-porous material to plug the hose and
nipples.
To prevent the entry of dust or other foreign bodies, plug the
dismantled hoses and compressor nipples.
.
<<B>> COMPRESSOR REMOVAL
Take care not to spill any compressor oil when removing the
compressor.
INSTALLATION SERVICE POINT
.
>>A<< FLEXIBLE SUCTION HOSE CONNECTION
To prevent mis-alignment of suction hose to bracket use the
folowing assembly procedure.
1. Insert hoseconnector into compressor and hand start bolt.
2. Assemble P-clip to hose and suction hose bracket. Tighten
bolt.
3. Tighten bolt between compressor and hose connector.
.
>>B<< COMPRESSOR INSTALLATION
If a new compressor is installed, first adjust the amount of oil
according to the procedures described below, and then install
the compressor.
1. Measure the amount (X ml) of oil within the removed
compressor.
2. Drain (from the new compressor) the amount of oil
calculated according to the following formula, and then
install the new compressor.
New compressor oil amount = 140 ml
140 ml
X ml = Y ml
NOTE: Y ml indicates the amount of oil in the refrigerant line,
the condenser, the evaporator, etc.
NOTE: When replacing the following parts at the same times as
the compressor, subtract the rated oil amount of each part from
Y ml and discharge from the new compressor.
Compressor oil: ND Oil 8
Quantity:
Evaporator: 40 ml
Condenser: 40 ml
Receiver: 40 ml

COMPRESSOR AIR CONDITIONING
COMPRESSOR CLUTCH OPERATION CHECK
Connect the compressor connector terminal to the battery posi-
tive (+) terminal and ground the battery’s negative (-) terminal
to the compressor unit. At that time, the air conditioning com-
pressor clutch should make a definite operating sound.
.
AIR GAP ADJUSTMENT
Check whether or not the air gap of the clutch is within the stan-
dard value.
Standard value:
0.35
0.60mm
NOTE: If there is a deviation of the air gap from the standard
value, assess the operation of the clutch and replace the com-
pressor assembly as required.

INSTALLATION SERVICE POINT
.
>>A<< DRYER REMOVAL PROCEDURE
1. Remove the condenser assembly from the vehicle to access
the modulator.
2. Remove the modulator cap using a14 mm hexagon wrench.
3. Remove the desiccant bag from the modulator.
Do not remove the desiccant bag from the plastic bag until
just before inserting it into the modulator.
.
<<B>> DRYER REPLACEMENT PROCEDURE
1. Fit the desiccant bag with the welded portion facing the
bottom of the modulator towards the screw-thread end.
2. Add 40 ml of ND Oil 8 into system to balance the oil
removed from the system.
3. Tighten the cap to the required torque.
2.9
1.0 Nm
Because the plastic cap has a large, 14 mm hex socket, it
is susceptible to generating excessive torque. Therefore,
be careful not to damage the crown portion of the cap.
