AIR CONDITIONER CONTROL
AIR CONDITIONER CONTROL
PFP:27500
DescriptionEJS006B0
The front air control provides automatic regulation of the vehicle's interior temperature. The system is based
on the driver's and passenger's selected “set temperature”, regardless of the outside temperature changes.
This is done by utilizing a microcomputer, also referred to as the front air control, which receives input signals
from the following six sensors:
lAmbient sensor
lIn-vehicle sensor
lIntake sensor
lOptical sensor (one sensor for driver and passenger side)
lPBR (Position Balanced Resistor).
lVehicle speed sensor
The front air control uses these signals (including the set temperature) to automatically control:
lOutlet air volume
lAir temperature
lAir distribution
The front air control is used to select:
lOutlet air volume
lAir temperature/distribution
OperationEJS006B1
AIR MIX DOORS CONTROL
The air mix doors are automatically controlled so that in-vehicle temperature is maintained at a predetermined
value by the temperature setting, ambient temperature, in-vehicle temperature and amount of sunload.
BLOWER SPEED CONTROL
Blower speed is automatically controlled by the temperature setting, ambient temperature, in-vehicle tempera-
ture, intake temperature, amount of sunload and air mix door position.
When AUTO switch is pressed, the blower motor starts to gradually increase air flow volume (if required).
When engine coolant temperature is low, the blower motor operation is delayed to prevent cool air from flow-
ing.
INTAKE DOOR CONTROL
The intake door is automatically controlled by the temperature setting, ambient temperature, in-vehicle tem-
perature, intake temperature, amount of sunload and the ON-OFF operation of the compressor.
MODE DOOR CONTROL
The mode door is automatically controlled by the temperature setting, ambient temperature, in-vehicle temper-
ature, intake temperature and amount of sunload.
DEFROSTER DOOR CONTROL
The defroster door is controlled by: Turning the defroster dial to front defroster.

ATC-112
TROUBLE DIAGNOSIS
Optical Sensor Circuit
EJS006BY
COMPONENT DESCRIPTION
The optical sensor is located in the center of the defroster 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 front air control.
OPTICAL INPUT PROCESS
The front air control includes a processing circuit which averages the variations in detected sunload over a
period of time. This prevents adjustments in the ATC 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 optical sensor will vary 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 ATC system operation. On the other hand, shortly
after entering a long tunnel, the system will recognize the change in sunload, and the system will react accord-
ingly.
DIAGNOSTIC PROCEDURE FOR SUNLOAD SENSOR
SYMPTOM: Sunload sensor circuit is open or shorted. (44 or 46 is
indicated on front air control as a result of conducting self-diagnosis).
1.CHECK CIRCUIT CONTINUITY BETWEEN SUNLOAD SENSOR AND FRONT AIR CONTROL
1. Turn ignition switch OFF.
2. Disconnect front air control connector and sunload sensor con-
nector.
3. Check continuity between sunload sensor harness connector
M63 terminal 1 and 2 and front air control harness connector
M61 terminal 29 and 37.
4. Check continuity between sunload sensor harness connector
M63 terminal 1 and 2 and ground.
OK or NG
OK >> GO TO 2.
NG >> Repair harness or connector.

REFRIGERANT LINES
CAUTION:
Replace the O-rings on the A/C low-pressure flexible A/C hose and the high-pressure A/C pipe with
new ones. Apply compressor oil to the O-rings for installation.
Removal and Installation for Expansion ValveEJS006CZ
REMOVAL
1. Discharge the refrigerant. Refer toATC-138, "HFC-134a (R-134a) Service Procedure".
2. Remove the heater and cooling unit assembly. Refer toATC-126, "
REMOVAL".
3. Remove the heater core and evaporator pipes grommet.
4. Remove the expansion valve.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
lReplace the O-rings on then expansion valve and the A/C refrigerant pipes with new ones, then
apply compressor oil to them for installation.
lAfter charging refrigerant, check for leaks.
Checking for Refrigerant LeaksEJS006D1
Perform a visual inspection of all refrigeration parts, fittings, hoses and components for signs of A/C lubricant
leakage, damage and corrosion. A/C lubricant leakage may indicate an area of refrigerant leakage. Allow
extra inspection time in these areas when using either an electronic refrigerant leak detector or fluorescent
dye leak detector.
If dye is observed, confirm the leak with an electronic refrigerant leak detector. It is possible a prior leak was
repaired and not properly cleaned.
When searching for leaks, do not stop when one leak is found but continue to check for additional leaks at all
system components and connections.
When searching for refrigerant leaks using an electronic leak detector, move the probe along the suspected
leak area at 1 to 2 inches per second and no further than 1/4 inch from the component.
CAUTION:
Moving the electronic leak detector probe slower and closer to the suspected leak area will improve
the chances of finding a leak.
Checking System for Leaks Using the Fluorescent Leak DetectorEJS006D2
1. Check A/C system for leaks 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 will appear 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) leak.
2. If the suspected area is difficult to see, use an adjustable mirror or wipe the area with a clean shop rag or
cloth, with the UV lamp for dye residue.
3. After the leak is repaired, remove any residual dye using dye cleaner [SST: J-43872] to prevent future mis-
diagnosis.
4. Perform a system performance check and verify the leak repair with an approved electronic refrigerant
leak detector.
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.
Cleanwithadryclothorblowoffwithshopair.
Do not allow the sensor tip of the detector to contact with any substance. This can also cause false readings
and may damage the detector.Expansion valve bolts : 4 N·m (0.41 kg-m, 35 in-lb)
