CHECK AUTO MODE

1. Press AUTO switch.

2. Operate temperature control switch to check that fan speed or air outlet changes (the air outlet or fan

speed varies depending on the ambient temperature, in-vehicle temperature (rear side), set temperature,

and etc.).

Is the inspection result normal?

YES

>> Inspection End.

NO

>> GO TO 7.

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-46, "DTC Index"

 and perform the appropriate diagnosis.

NO

>> Refer to 

HAC-146, "Diagnosis Chart By Symptom"

 and perform the appropriate diagnosis.

FRONT AUTOMATIC AIR CONDITIONING SYSTEM
FRONT AUTOMATIC AIR CONDITIONING SYSTEM : Temperature Setting Trimmer 
(Front)

INFOID:0000000009176810

DESCRIPTION

If the temperature felt by the customer is different from the front air flow temperature controlled by the temper-

ature setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature set-

ting.

HOW TO SET

With CONSULT

Perform “TEMP SET CORRECT” of HVAC work support item. 

NOTE:

• When 

−3.0°C (−6°F) is corrected on the temperature setting set as 25.0°C (77°F) the temperature controlled

by A/C auto amp. is 25.0

°C (77°F) −3.0°C (−6°F) = 22.0°C (72°F) and the temperature becomes lower than

the temperature setting. 

• When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10

V or less, the setting of the difference between the set temperature and control temperature may be can-

celled. 

FRONT AUTOMATIC AIR CONDITIONING SYSTEM : Foot Position Setting Trimmer

INFOID:0000000009176811

DESCRIPTION

In FOOT mode, the air blowing to DEF can change ON/OFF. 

HOW TO SET

With CONSULT

Perform the “BLOW SET” of HVAC work support item.

FRONT AUTOMATIC AIR CONDITIONING SYSTEM : Inlet Port Memory Function 
(FRE)

INFOID:0000000009176812

DESCRIPTION

• If the ignition switch is turned to the OFF position while the intake switch is set to OFF (fresh air intake), “Per-

form 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:

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 memory function may be cancelled. 

FRONT AUTOMATIC AIR CONDITIONING SYSTEM : Inlet Port Memory Function 
(REC)

INFOID:0000000009176813

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:

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 memory function may be cancelled.

SYSTEM SETTING

If the temperature felt by the customer is different from the rear air flow temperature controlled by the temper-

ature setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature set-

ting. 

HOW TO SET

With CONSULT

Perform “REAR TEMP SET CORRECT” of HVAC work support item. 

NOTE:

• When 

−3.0°C (−6°F) is corrected on the temperature setting set as 25.0°C (77°F) the temperature controlled

by A/C auto amp. is 25.0

°C (77°F) −3.0°C (−6°F) = 22.0°C (72°F) and the temperature becomes lower than
