A/C AND AV SWITCH SYSTEM
Refer to Owner′s Manual for A/C and AV switch operating instructions.
Using the A/C and AV switch at the center of the instrument panel, the controls of the following systems are
centralized:

Integrated display system (Drive computer, setting screen, etc.)

Auto A/C system

Audio system
PRECAUTION OF LCD MONITOR

In order to use LED for backlight of a display, by interior temperature, brightness may change. In low tem-
perature, the refreshing rate of the picture also becomes low because of the low response of the LCD
monitor. When the interior becomes warm, however, the LCD recovers the normal display.

Backlight sometimes flickers or darkens according to the wearing out of LCD and the number of times
switched ON and OFF. In this case, display unit should be replaced. (Exchange only of backlight is impos-
sible.)
POWER SUPPLY AND GROUND
Power is supplied at all times

through 15A fuse (No. 32, located in fuse and fusible link box)

to audio unit terminal 6

to display unit terminal 1 and

to A/C and AV switch terminal 1.
When ignition switch is in ACC or ON position, power is supplied

through 10A fuse [No. 6, located in fuse block (J/B)]

to unified meter and A/C amp. terminal 35

to audio unit terminal 10

to display unit terminal 2 and

to A/C and AV switch terminal 2.
When ignition switch is in ON or START position, power is supplied

through 10A fuse [No. 12, located in fuse block (J/B)]

to unified meter and A/C amp. terminal 22 and

to display unit terminal 3.
Ground is supplied

to unified meter and A/C amp. terminals 29, 30

to display unit terminals 6 and 15 and

to A/C and AV switch terminal 5

through body grounds M35, M45 and M85.
Ground is supplied through the case of the audio unit.

Panic Alarm Operation
When key switch is OFF (when ignition key is not inserted in key cylinder), BCM turns on and off horn and
headlamp intermittently with input of PANIC ALARM signal from key fob.
The alarm automatically turns off after 25 seconds or when BCM receives any signal from key fob.
Panic alarm operation mode can be changed using “PANIC ALARM SET” mode in “WORK SUPPORT”.
Refer to BL-68, "
Work Support" .
For detailed description, refer to BL-186, "
VEHICLE SECURITY (THEFT WARNING) SYSTEM" .
Keyless Power Window Down (Open) Operation
When key fob unlock switch is turned ON with ignition switch OFF, and key fob unlock switch is detected to be
on continuously for 3 seconds, the driver's door and passenger's door power windows are simultaneously
opened.
Power window is operated to open and the operation continues as long as the key fob unlock switch is
pressed.
Keyless power window down operation mode can be changed using “PW DOWN SET” mode in “WORK SUP-
PORT”. Refer to BL-68, "
Work Support"
Room Lamp and Ignition Key Ring Illumination Operation
When the following conditions come:

condition of interior lamp switch is DOOR position;

door switch OFF (when all the doors are closed);
Remote keyless entry system turns on interior lamp (for 30 seconds) with input of UNLOCK signal from key
fob. For detailed description, refer to LT- 1 5 9 , "
INTERIOR ROOM LAMP" .
CAN Communication System DescriptionAIS004MC
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

accepted, a door lock or door unlock request signal is sent to BCM via CAN communication to lock/unlock
the door.

When door lock/unlock is performed using Intelligent Key remote controller button operation, operation
confirmation is conducted by making hazard lamps flash and Intelligent Key warning buzzer sound.
OPERATION CONDITION
Door lock/unlock operation is necessary for all doors close.
Map Lamp And Keyhole Illumination Function
When the following conditions come:

condition of map lamp switch is DOOR position;

door switch OFF (when all the doors are closed);
Remote control button of Intelligent Key turns on interior lamp (for 30 seconds) with input of UNLOCK signal
from Intelligent Key.
Panic Alarm Function
When key switch is OFF and ignition knob is not pushed (when mechanical key is not inserted in ignition
knob), BCM turns ON and OFF horn and headlamp intermittently with input of PANIC ALARM signal from
Intelligent Key. The alarm automatically turns off after 25 seconds or when Intelligent Key unit receives any
signal from Intelligent Key.
Panic alarm operation mode can be changed using “WORK SUPPORT” mode in “PANIC ALARM DELAY”.
Refer to BL-120, "
WORK SUPPORT" .
Remote Control Power Window Down (Open) Operation
When Intelligent Key unlock switch is turned ON with ignition switch OFF, and Intelligent Key unlock switch is
detected to be on continuously for 3 seconds, the driver's door and passenger's door power windows are
simultaneously opened.
Power window is operated to open and the operation continues as long as the Intelligent Key unlock switch is
pressed.
Remote control power window down operation mode can be changed using “P/W DOWN DELAY” mode in
“WORK SUPPORT”. Refer to BL-120, "
WORK SUPPORT" .
Key Reminder Function
As an operation verification function, when doors are locked or unlocked using Intelligent Key remote control-
ler button operation, hazard lamps flash and horn sounds.
ENGINE STARTUP FUNCTION
Operation Description

When ignition knob is pressed, Intelligent Key unit sends request signal from inside key antenna, key-ID
verification is conducted with Intelligent Key using two-way communication, and if verification is success-
ful, an ignition rotation prohibition latch release signal is sent to steering lock unit. Steering lock unit
releases ignition knob rotation prohibition latch. (Ignition knob can now be turned.)

When it becomes possible to rotate the ignition knob, “KEY” warning lamp in combination meter lights up
green to notify driver that ignition knob can be turned.
NOTE:
When it becomes impossible to rotate the ignition knob, “KEY” warning lamp in combination meter lights
up red.

When key-ID verification is successful and ignition knob switch is in the ON state, Intelligent Key unit uses
CAN communication to send engine start permission signal to BCM.

When BCM receives engine start permission signal, it uses CAN communication to sent starter request
signal to IPDM E/R so that the engine will start when ignition knob is rotated to START position.
Operation Range
Engine can be started when Intelligent Key is in the vehicle. However, sometimes engine might not start when
Intelligent Key is on instrument panel, rear parcel shelf, or in glove box.
