°

C.

3.

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.).

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> GO TO 10.

10.

CHECK SELF-DIAGNOSIS WITH ON BOARD DIAGNOSIS SYSTEM

1.

Perform self-diagnosis with on board diagnosis.

2.

Check that any whether malfunction result is detected.

Is any malfunction result detected?

YES

>> Refer to 

HAC-45, "Diagnosis Description"

 and perform the appropriate diagnosis.

NO

>> GO TO 11.

11.

CHECK SELF-DIAGNOSIS WITH CONSULT

1.

Perform self-diagnosis with CONSULT.

2.

Check that any DTC is detected.

Is any DTC detected?

YES

>> Refer to 

HAC-53, "DTC Index"

, and perform the appropriate diagnosis.

NO

>> GO TO 12.

12.

CHECK FAIL-SAFE ACTIVATION

Check that symptom is applied to the fail-safe activation. Refer to 

HAC-53, "Fail-safe"

.

>> Refer to 

HAC-121, "Symptom Table"

, and perform the appropriate diagnosis.

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 

−

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.
