HAC-81, "Configuration List"

.

CAUTION:

• Thoroughly read and understand the vehicle specification. Incorrect settings may result in abnormal

control of ECU.

• Make sure to select “SETTING” even if the indicated configuration of brand new A/C auto amp. is

Temperature Setting Trimmer

INFOID:0000000010121970

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” in “Work support” of “HVAC”. 

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 12V battery cable is disconnected from the negative terminal or when the 12V battery voltage

becomes 10 V or less, the setting of the difference between the set temperature and control temperature

may be cancelled. 

Inlet Port Memory Function (REC)

INFOID:0000000010121971

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” is set, the intake switch is ON (recirculation) when turning the ignition switch to the

ON position again.
