DUAL A/C

LCD panel <DUAL A/C>

The following heater controller has been adopted.

• To enhance luxurious appearance and conven-

ience, a liquid crystal display panel has been 
adopted.

• A white character LCD is adopted in order to pro-

vide a better visibility.

• Ergonomic layout of the control panel allows the 

driver to check the current status without less eye 
movement.

• The smoke-shaded LCD screen provides a luxury 

image.

AIR CONDITIONER CONTROL SYSTEM

M2551002800033

General

The air conditioner system with following features 
has been adopted.

• If the heater fan runs at higher stage, the recircu-

lation ratio of heated air will be increased, thus 
improving heating performance.

• The heating performance is enhanced by 

increasing air volume.

• The heating performance is enhanced by restrict-

ing minimum air volume at low ambient tempera-
ture (-5

°C or less).

• The interior temperature sensor can measure 

temperature more precisely due to better sealing 
around it. This improves the response and com-
fort of the automatic air conditioner.

CUSTOMIZATION FUNCTION

CONTROL

FORCED DEF CONTROL

When air outlet position is switched to DEF, A/C is 
automatically turned ON, and outside/inside air 
selection damper is set to the fresh air position to 
quickly defrost the windshield screen.

MAX COOL, MAX HOT CONTROL 

When the set temperature is at MAX COOL (15

°C) or 

at MAX HOT (29

°C) with the air outlet and air volume 

at the AUTO positions, the following controls are 
made automatically by the A/C-ECU.

NOTE: "*" indicates that when the automatic control 
is not cancelled using the customise function, the 
manual operation is disabled.

IDLE-UP CONTROL 

A/C-ECU and the engine-ECU communicate with 
each other through the CAN communication. The 
idle-up speed of the engine is controlled in two steps 
depending on the A/C load to secure the air cooling 
performance during summer and to enhance fuel 
economy in seasons with moderate temperature.

DETECTION CONTROL FOR 
REFRIGERANT LEAKS 

A/C-ECU determines if the refrigerant amount is less 
than specified or refrigerant pressure is abnormal by 
using the ambient temperature (ambient temperature 
sensor to measure refrigerant inflation rate) and 
refrigerant pressure (measured by the A/C pressure 
sensor). When refrigerant amount or refrigerant pres-
sure is judged abnormal, the compressor is cut-off to 
protect the A/C system.

PROTECTION CONTROL AT AIR BAG 
DEPLOYMENT (DURING COLLISION)

When the air bag deployment is detected, the A/C 
system is stopped.

COMMUNICATION

A/C-ECU performs the signal transmission and 
reception with each ECU via CAN (Controller Area 
Network)*. 

NOTE: *: For details of CAN communication, refer to 
GROUP 54C 

−

 Controller Area Network .

DIAGNOSTIC FUNCTION

A/C-ECU has the following functions for easier sys-
tem checks.

• DIAGNOSTIC FUNCTION

• Service data output

• Actuator test

NOTE: For each item, refer to the Workshop Manual.

CUSTOMIZATION FUNCTION

M2551003000018

By operating the M.U.T.-III ETACS system, the fol-
lowing functions can be customised. The pro-
grammed information is held even when the battery 
is disconnected.
