SYSTEM INITIALIZATION

Initialize the system if any of the following work has been done.
• Electric power supply to power window switch or motor is interrupted by blown fuse or disconnecting battery

cable, etc.

• Removal and installation of the regulator assembly.
• Removal and installation of the motor from the regulator assembly.
• Removal and installation of the harness connector of the power window switch.
• Removal and installation of the door glass.
• Removal and installation of the front door glass run.
• Disconnection and connection of the minus terminal of the battery.

Initialization

Follow the steps below after installing each component to the vehicle.

Disconnect the minus terminal of battery or disconnect power window switch harness connector tempo-
rarily. Then reconnect after at least 1 minute.

Turn ignition switch ON.

Operate power window switch to fully open the window.

Draw fully the power window switch in the up direction (auto close position) and hold. Continue holding
the switch even when window is completely closed and then release after more than 3 seconds.

Inspect the anti-pinch system function.
NOTE:
Initialization may be cancelled with continuous opening and closing operation. In this case, initialize the
system.

FRONT DOOR GLASS

GW-19

< ON-VEHICLE REPAIR >

Fully open the door glass.

Place a wooden piece (wooden hammer handle, etc.) at near fully closed position.

Perform fully closing operation with auto up switch.

• Check that the glass reverses without pinching the wooden piece, is lowered approximately 150 mm (5.906

in) or for more than 3 seconds and then stops.

• The glass should not be raised with power window main switch operated while it is reversing or lowering.

CAUTION:

• Be careful not to be pinched.
• Check that the auto up function is normal before the inspection following the system initialization.

FITTING INSPECTION

• Check that the glass is fit securely into the sash groove.
• Lower the glass slightly [approximately 10 to 20 mm (0.394 to 0.787 in)], and check that the clearance to the

sash is parallel. Loosen the regulator mounting bolts, guide rail mounting bolts, and glass and guide rail
mounting bolts to correct the glass position if the clearance between the glass and sash is not parallel.

System Diagram

INFOID:0000000003072948

System Description

INFOID:0000000003072949

REFRIGERANT CYCLE

Refrigerant Flow

The refrigerant flows from the compressor, through the condenser with a liquid tank, through the evaporator,
and then back to the compressor. The refrigerant evaporation in the evaporator is controlled by an externally
equalized expansion valve, located at dash panels.

Freeze Protection

To prevent the evaporator from freezing up, the evaporator air temperature is monitored, and the voltage sig-
nal to the A/C auto amp. turns the A/C relay OFF and stops the compressor.

REFRIGERANT SYSTEM PROTECTION

Refrigerant Pressure Sensor

The refrigerant system is protected against excessively high or low-pressures by the refrigerant pressure sen-
sor, located on the liquid tank. The refrigerant pressure sensor detects the pressure inside the refrigerant line
and sends the voltage signal to the ECM if the system pressure rises above, or falls below the specifications.
ECM turns the A/C relay OFF and stops the compressor when pressure on the high-pressure side detected by
the refrigerant pressure sensor is over approximately 3,119 kPa (31.8 kg/cm

, 452 psi) or below approximately

118 kPa (1.2 kg/cm

, 17 psi).

Pressure Relief Valve

The refrigerant system is also protected by a pressure relief valve, located in the rear head of the compressor.
The release port on the pressure relief valve automatically opens and releases refrigerant into the atmosphere
when the pressure of the refrigerant in the system increases to an unusual level [more than 3,600 kPa (36.7
kg/cm

, 522 psi)].

Component

Description

Compressor

Intakes, compresses, and discharges refrigerant, to circulate refrigerant inside the refrigerant cycle.

Condenser

Cools refrigerant discharged from compressor, and transforms it to liquid refrigerant.

Liquid tank

Eliminates foreign material in refrigerant, and temporarily stores liquid refrigerant.

Refrigerant pressure sensor

Refer to

EC-463, "Description"

Evaporator

The mist form liquid refrigerant transforms to gas through evaporation by the air conveyed from the
blower motor. The air is cooled by the heat from evaporation.

Expansion valve

Transforms high-pressure liquid refrigerant to mist form from low-pressure liquid refrigerant by the
drawing function.

Blower motor

Takes in air from the vehicle or fresh outside air, provides it forcedly pushes it into to the air condi-
tioner, and circulates it inside the vehicle.
