GENERAL DESCRIPTION

OPERATION
.
CONDENSER FAN AND RADIATOR FAN
CONTROL
The ECU judges the required revolution speed of
radiator fan motor and condenser fan motor using
the input signals transmitted from A/C switch, output
shaft speed sensor and engine coolant temperature
sensor. The ECU activates the fan control relays to
drive the radiator fan motor and condenser fan
motor.
.
COMPRESSOR CONTROL
When operating the air conditioning switch
The air thermo sensor, which senses the temper-
ature of the air flowing out of the evaporator,
deactivates the compressor at 3
C (37.4F) or
below.
The dual pressure switch turns OFF when the
refrigerant pressure becomes excessively high or
low, thus protecting the compressor circuit (See
Table below).
When the air thermo sensor is activated, and the
ignition switch, blower switch, and air condition-
ing switch are ON, the A/C compressor clutch
relay is energized.
When operating the mode selection dial
The air conditioning will work when the mode
selection dial is set to the "Defroster" or
"Defroster/foot" position, or the temperature con-
trol dial is set to the "MAX A/C" position. In other
dial positions, when the air conditioning switch is
turned on, the air conditioning will work.
A/C Compressor Clutch Relay ON Conditions
Ignition switch (IG2) ONNOTE: A/C compressor clutch relay is
de-energized when any one switch, sensor
or control unit shown on the left turns off.
NOTE: The components marked by

communicate with the ECU. If the air thermo
sensor detects a temperature of 3
C
(37.4
F), the A/C-ECU will turn off the A/C
compressor clutch relay. Blower switch ON

REMOVAL SERVICE POINTS
.
<> FLEXIBLE SUCTION HOSE AND LIQUID
PIPE A 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 hose and condenser assembly nipples.
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.
.
<> 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.
