CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to “sleep mode”, potentiall y causing a discharged battery and a no-start condition.
NOTE:
This vehicle is diagnosed using the CONSULT-III plus.
• When CONSULT is connected with a data link connector equipped on the vehicle side, it will communicate with the control unit
equipped in the vehicle and then enable various kinds of diagnos-
tic tests.
• Refer to “CONSULT-III plus Operation Manual” for more informa- tion.

PRECAUTIONS
Be certain that the gauge face indicates R-134a or 134a. Make sure
the gauge set has 1/2 ″-16 ACME threaded connections for service
hoses. Confirm the set has been used only with refrigerant HFC-
134a (R-134a) along with specified oil.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or aut omatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Do not attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC134a (R-134a) and specified
oils have been used with the scale. If the scale controls refrigerant
flow electronically, the hose fitting must be 1/2”-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder's top valve
when filling the cylinder with refrigerant. Also, the accu racy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.

1. Before connecting recovery/recycling equipment to vehicle, check recovery/recycling equipment gauges.
No refrigerant pressure should be displayed. If NG, recover refrigerant from equipment lines.
2. Connect recovery/recycling equipment to vehicle. Confi rm refrigerant purity in supply tank using recovery/
recycling equipment and refrigerant identifier. If NG, refer to HA-3, "Precaution for Working with HFC-134a
(R-134a)".
3. Confirm refrigerant purity in vehi cle A/C system using recovery/recycling equipment and refrigerant identi-
fier. If NG, refer to HA-3, "Precaution for Working with HFC-134a (R-134a)"
.
4. Discharge refrigerant into the refrigerant recove ry/recycling equipment. Measure oil discharged into the
recovery/recycling equipment.
Replace liquid tank 5 (0.2, 0.2)

OPERATION
AUTO switchTurns the switch indicator lamp and "AUTO" indicator on the display ON, and then front air condition-
ing system becomes the following state.
• Air inlet: Automatic control
• Air outlet: Automatic control
• Blower fan: Automatic control
• Compressor: ON
Defroster switch Turns defroster mode (swi
tch indicator) between ON ⇔ OFF each time.
When defroster switch is pressed while front air conditioning system is in the ON position.
• When defroster mode is turned ON, front air conditioning system becomes the following state.
- Air inlet: Fresh air intake
- Air outlet: DEF
- Blower fan: Automatic control (If fan speed other than AUTO is selected before pressing defroster
switch, fan speed is manual control.)
- Compressor: ON
• When defroster mode is turned OFF, front air conditioning system state returns to the previous state
before defroster mode is selected. But, the following state is continued.
- Air inlet: Fresh air intake
- Compressor: ON
When defroster switch is pressed while front air conditioning system is in the OFF position.
• When defroster mode is turned ON, front air conditioning system becomes the following state.
- Air inlet: Fresh air intake
- Air outlet: Defroster
- Blower fan: Automatic control
- Compressor: ON
• When defroster mode is turned OFF, entire front air conditioning system is set to auto mode.
NOTE:
When defroster mode turns ON while front air conditioning system is in automatic control (“AUTO” is
indicated), automatic control is released (“AUTO” turns OFF).
DUAL switch • Turns left and right ventilation temperature control (switch indicator) between ON
⇔ OFF each
time.
• When DUAL switch indicator is ON, the driver side and passenger side temperatures can each be
set independently.
• When DUAL switch indicator is OFF, the driver side outlet and setting temperature is applied to both sides.
• Left and right ventilation temperature control is cancelled by turning the DEF mode ON.
NOTE:
When front air conditioning system is in the OFF position, left and right ventilation temperature control
can be selected only while front air conditioning system state (when MODE switch is pressed) is in-
dicated on the display.
Fan switch (UP/DOWN) Blower fan speed is manually controlled with these switches. Seven speeds are available for manual
control (as shown on the display screen).
NOTE:
• When fan switch is pressed while front air conditioning system is in OFF, front air conditioning sys- tem is activated. (Compressor control state returns to the previous state before front air condition-
ing system OFF.)
• When fan switch is pressed while front air conditioning system is in automatic control (“AUTO” is indicated), automatic control is released (“AUTO” turns OFF).
A/C switch Compressor control (switch in
dicator) changes between ON ⇔ OFF each time this switch is pressed
while front blower motor is operated.
NOTE:
• A/C switch cannot be turned ON when front blower motor is OFF.
• A/C switch cannot be turned OFF when air outlet is D/F or DEF.
• Air inlet changes to fresh air intake when A/C switch is turned OFF while air inlet is set to recircu- lation.
MODE switch Selects air outlet sequentially from VENT
⇒ B/L ⇒ FOOT ⇒ D/F ⇒ VENT each time.
NOTE:
• When front air conditioning system is in the OFF position, air outlet can be selected.
• When MODE switch is pressed while front air conditioning system is in automatic control (“AUTO” is indicated), automatic control is released (“AUTO” turns OFF).
ON/OFF switch • Turns front air conditioning system ON/OFF.
• When front air conditioning system turns OFF, air inlet and air outlet become the automatic control.

NOTE:
When front air conditioning system is in the OFF position, air inlet can be selected.
Recirculation switch Air inlet changes to reci
rculation (REC) when this switch is pressed.
• Recirculation switch indicator ON: Recirculation
• Recirculation switch indicator OFF: Fresh air intake
NOTE:
• When front air conditioning system is in the OFF position, air inlet can be selected.
• When MODE switch and DEF switch is in the D/F or DEF position, air inlet cannot be selected to recirculation (REC).
Temperature control dial
(Driver side) Setting temperature is selected using this dial within a range between 18
°C (60 °F) and 32 °C (90 °F)
at a rate of 0.5 °C (1.0 °F) per adjustment.
NOTE:
When air conditioning system is OFF, setting temperature can be selected only while air conditioning
system status screen [only when MODE switch (driver side) is pressed] is indicated on display.
Temperature control dial
(Passenger side) • Outlet air flow temperature of passenger side can be changed without changing outlet air flow tem-
perature of driver side.
• Setting temperature is selected using this dial within a range between 18 °C (60 °F) and 32 °C (90 °F)
at a rate of 0.5 °C (1.0 °F) per adjustment.
NOTE:
• When air conditioning system is OFF, setting temperature can be selected only while air condition-
ing system status screen [only when MODE switch (passenger side) is pressed] is indicated on dis-
play.
• When DEF mode is ON, temperature control dial (passenger side) is inoperative.
