OPERATION INSPECTION
7.
CHECK WITH TEMPERATURE SETTING LOWERED
1.
Operate compressor.
2.
Operate temperature control dial (driver side) to lower the set temperature to 18.0
°
C.
3.
Check that cool air blows from the air outlets.
Is the inspection result normal?
YES
>> GO TO 8.
NO

Warm up engine to the normal operating temperature.
2.
Operate temperature control dial (driver side) to raise the set temperature to 32.0
°
C.
3.
Check that warm air blows from the air outlets.

YES
>> GO TO 9.
NO
>> GO TO 10.
9.
CHECK AUTO MODE
1.
Press AUTO switch and check that AUTO” indicator turns ON.
2.
Operate temperature control dial (driver side) to check that fan speed or air outlet changes (the air outlet
or fan speed varies depending on the ambient temperature, in-vehicle temperature, set temperature, and
etc.).

Temperature Setting Trimmer
INFOID:0000000010432192
DESCRIPTION
If the temperature felt by the customer is different from the air flow temperature controlled by the temperature
setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature setting.
HOW TO SET
With CONSULT
Perform “TEMP SET CORRECT” of HVAC work support item.
NOTE:
• When
−

C is corrected on the temperature setting set as 25.0
°
C the temperature controlled by A/C auto
amp. is 25.0

C and the temperature becomes lower than the temperature setting.
• A/C auto amp. stores the setting at the time 1 minute after the ignition switch turns OFF.
• When the battery cable is disconnected from the negative terminal or when the battery voltage is 10 V or
less, the setting for the difference between the set temperature and control temperature is set to the value
stored 1 minute after most recent ignition switch OFF status.
Inlet Port Memory Function (REC)
INFOID:0000000010432193
DESCRIPTION
• If the ignition switch is turned to the OFF position while the INTAKE switch is set to ON (recirculation), “Per-
form the memory” or “Do not perform the memory” of INTAKE switch ON (recirculation) condition can be
selected.
• If “Perform the memory” was set, the INTAKE switch will be ON (recirculation) when turning the ignition
switch to the ON position again.
• If “Do not perform the memory” was set, the air inlets will be controlled automatically when turning the igni-
tion switch to the ON position again.
HOW TO SET
With CONSULT
Perform the “REC MEMORY SET” of HVAC work support item.
NOTE:
• A/C auto amp. stores the setting at the time 1 minute after the ignition switch turns OFF.

SYSTEM SETTING
• When the battery cable is disconnected from the negative terminal or when the battery voltage is 10 V or
less, the setting for the difference between the set temperature and control temperature is set to the value
stored 1 minute after most recent ignition switch OFF status.
Inlet Port Memory Function (FRE)
INFOID:0000000010432194
DESCRIPTION
• If the ignition switch is turned to the OFF position while the INTAKE switch is set to OFF (fresh air intake),
“Perform the memory” or “Do not perform the memory” of INTAKE switch OFF (fresh air intake) condition can
be selected.
• If “Perform the memory” was set, the INTAKE switch will be OFF (fresh air intake) when turning the ignition
switch to the ON position again.
• If “Do not perform the memory” was set, the air inlets will be controlled automatically when turning the igni-
tion switch to the ON position again.
HOW TO SET
With CONSULT
Perform the “FRE MEMORY SET” of HVAC work support item.
NOTE:
• A/C auto amp. stores the setting at the time 1 minute after the ignition switch turns OFF.
• When the battery cable is disconnected from the negative terminal or when the battery voltage is 10 V or
less, the setting for the difference between the set temperature and control temperature is set to the value
stored 1 minute after most recent ignition switch OFF status.
Setting of Target Evaporator Temperature Upper Limit Value
INFOID:0000000010432195
DESCRIPTION
Setting of upper limit value of target evaporator temperature can be changed. Control characteristic of com-
pressor control (refrigerant discharge amount control) changes according to change of the setting, and then
operation ratio of compressor and refrigerant discharge amount are changed. According to change of the set-
ting, control characteristic focusing on the fuel consumption can be adjusted to control characteristic focusing
on the cooling capacity.
HOW TO SET
With CONSULT
Perform “TARGET EVAPORATOR TEMP UPPER LIMIT SETTING” in “WORK SUPPORT” mode of “HVAC”
using CONSULT.
