Operate the temperature control switch (driver side) and lower the temperature setting to 18
°
C (60
°
F).
3.
Check that the cool air blows from the outlets.
Is the inspection result normal?
YES
>> GO TO 7.
NO
>> Insufficient cooling:
HAC-88, "Inspection procedure"
.
7.
CHECK WITH TEMPERATURE SETTING RAISED
1.
Operate the temperature control switch (driver side) and raise the temperature setting to 32
°
C (90
°
F) after
warming up the engine.
2.
Check that the warm air blows from the outlets.
Is the inspection result normal?
YES
>> GO TO 8.
NO
>> Insufficient heating:
HAC-91, "Inspection procedure"
8.
CHECK LEFT AND RIGHT VENTILATION TEMPERATURE SEPARATELY CONTROL SYSTEM FUNC-
TION
1.
Press the DUAL switch, and then check that “DUAL” is shown on the display.
2.
Operate the temperature control switch (driver side). Check that the discharge air temperature (driver
side) changes.
3.
Operate the temperature control switch (passenger side). Check that the discharge air temperature (pas-
senger side) changes.
4.
Press the DUAL switch, and then check that the temperature setting (LH/RH) is unified to the driver side
temperature setting.
Is the inspection result normal?
YES
>> GO TO 9.
NO
>> Refer to
HAC-87, "Diagnosis Chart By Symptom"
and perform the appropriate diagnosis.
9.
CHECK AUTO MODE
1.
Press the AUTO switch, and then check that “AUTO” is shown on the display.
2.
Operate the temperature control switch (driver side). Check that the fan speed or outlet changes (the dis-
charge air temperature or fan speed varies depending on the ambient temperature, in-vehicle tempera-
ture, and temperature setting).
Is the inspection result normal?
YES
>> GO TO 10.
NO
>> Refer to
HAC-87, "Diagnosis Chart By Symptom"
and perform the appropriate diagnosis.

2.
Operate the temperature control switch (driver side). Check that the fan speed or outlet changes (the dis-
charge air temperature or fan speed varies depending on the ambient temperature, in-vehicle tempera-
ture, and temperature setting).

and perform the appropriate diagnosis.
Temperature Setting Trimmer
INFOID:0000000003846292
DESCRIPTION
If the temperature felt by the customer is different than 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
Using CONSULT-III, perform “TEMP SET CORRECT” on “WORK SUPPORT” of HVAC.
NOTE:
• When the temperature setting is set to 25.0
°
C (77
°
F) and
−
3.0
°
C (
−
6
°
F), the temperature controlled by A/C
auto amp. is 25.0
°
C (77
°
F)
−
3.0
°
C (6
°
F) = 22.0
°
C (71
°
F) and the temperature becomes lower than the tem-
perature setting.
• When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10
V or less, trimmer operation is canceled. Temperature set becomes that of initial condition.
Foot Position Setting Trimmer
INFOID:0000000003846293
DESCRIPTION
In the FOOT mode, the air blowing to the DEF can be turned ON/OFF.
HOW TO SET
Using CONSULT-III, perform “BLOW SET” on “WORK SUPPORT” of HVAC.

Inlet Port Memory Function (FRE)
INFOID:0000000003846294
DESCRIPTION
• If the ignition switch is turned to the OFF position while the FRE switch is set to ON (fresh air intake), “Per-
form the memory” or “Do not perform the memory” of the FRE switch ON (fresh air intake) condition can be
selected.
• If “Perform the memory” was set, the FRE switch will be ON (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
Using CONSULT-III, perform “FRE MEMORY SET” on “WORK SUPPORT” of HVAC.
NOTE:
When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10 V
or less, the setting of the FRE switch memory function may be cancelled.
Inlet Port Memory Function (REC)
INFOID:0000000003846295
DESCRIPTION
• If the ignition switch is turned to the OFF position while the REC switch is set to ON (recirculation), “Perform
the memory” or “Do not perform the memory” of the REC switch ON (recirculation) condition can be
selected.
• If “Perform the memory” was set, the REC 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
Using CONSULT-III, perform “REC MEMORY SET” on “WORK SUPPORT” of HVAC.
NOTE:
When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10 V
or less, the setting of the REC switch memory function may be cancelled.
