registered with the vehicle's garage door opener. After registration, the vehicle's garage door opener can mimic
the signal of the transmitter systems and the original transmitters of each transmitter system are not needed.
1.RESISTER TRANSMITTER CODE
HINT:
The vehicle's garage door opener records transmitter codes for systems such as garage doors, gates,
entry gates, door locks, home lighting systems, security systems or other transmitter code based
systems.
The garage door opener is built into the dome lamp No. 1. If replacing the dome lamp No. 1,
transmitter codes for any systems previously registered in the garage door opener must be re-
registered.
a. Re-register systems in the garage door opener registration mode.
HINT:
3 transmitter codes can be registered with the garage door opener, one transmitter code for
each of the 3 garage door opener switches.
Disconnecting the battery will not erase the transmitter codes registered with the garage door
opener.
An attempt to overwrite a previously registered transmitter code with a new system's
transmitter code may fail. In these situations, the previously registered transmitter code will
not be erased.
1. Select a
garage door opener switch for transmitter code registration.

2.INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
a. This is a method in which trouble is located by using a manifold gauge set. Read the manifold
gauge pressure when these conditions are established.
Test conditions:
Temperature at the air inlet with the switch set at RECIRC is 30 to 35°C (86 to 95°F)
Engine is running at 2,000 rpm
Blower speed control switch is at "HI"
Temperature control dial is at "COOL"
HINT:
It should be noted that the gauge indications may vary slightly due to ambient temperature
conditions.
1. Normally functioning refrigeration system
Gauge reading:
Low pressure side: 0.15 to 0.25 MPa (1.5 to 2.5 kgf/cm
2 )
High pressure side: 1.37 to 1.57 MPa (14 to 16 kgf/cm
2 )

35.ADJUST WATER VALVE CONTROL CABLE
a. Turn the ignition switch to the ON position.
b. Disconnect the control cable.
c. Set the temperature control switch to "MAX. COOL".
d. Set the water valve lever to the "COOL" position, connect the control cable and lock the clamp.
HINT:
Lock the clamp while lightly pushing the outer cable in the direction shown in Fig. 67
by an arrow.

Installation is in the reverse order of removal.

INSPECTION
1.INSPECT REAR BLOWER MOTOR CIRCUIT (See REAR BLOWER MOTOR CIRCUIT
)
2.EXHAUST DAMPER CONTROL SERVOMOTOR CIRCUIT (See EXHAUST DAMPER
CONTROL SERVOMOTOR CIRCUIT )
3.INSPECT REAR MAGNETIC VALVE CIRCUIT (See REAR MAGNETIC VALVE CIRCUIT
)
4.INSPECT SMOKE SENSOR CIRCUIT (See SMOKE SENSOR CIRCUIT
)
5.INSPECT EVAPORATOR SUB-ASSY (REAR)
a. Check the evaporator sub-assy (rear) fins for blockage.
If the fins are clogged, clean them with compressed air.
b. Check the fitting for cracks or scratches.
If necessary, repair or replace.
6.INSPECT COOLING BOX LAMP SUB-ASSY
a. Connect positive (+) lead to terminal 1 and negative (-) lead to terminal 2.
b. Check that the cooling box lamp sub-assy comes on.
If coolin
g box light does not come on, replace the cooling box lamp sub-assy.
