A/C and AV Switch Self-Diagnosis FunctionBKS0022A
Performing self-diagnosis makes it possible to check operation of A/C and AV switch indicator (LED) and other
switches.
STARTING THE SELF-DIAGNOSIS MODE
1. Turn ignition switch OFF.
2. With three switches (DEF, REC/FRE and MODE) pressed simul-
taneously, turn the ignition switch to ACC.
DIAGNOSIS FUNCTION
The following are checked:

All the indicators (LED) in the A/C and AV switch.

Continuity of the switches by sounding the buzzer when pressing the A/C and AV switch.
NOTE:

Indicators (LED) of REC/FRE switch change to “FRE” → “REC” → “FRE” every time the REC/FRE switch
is pressed. (These two do not turn on at the same time.)

Impossible to check rear window defogger switch operation (No beep sound even under normal status).
EXITING THE SELF-DIAGNOSIS MODE

Turn ignition switch OFF.

INTEGRATED COLOR DISPLAY SYSTEMPFP:28090
System DescriptionBKS0027J
For system operation information, refer to Owner's Manual.
INTEGRATED COLOR DISPLAY SYSTEM

Each control unit that comprises the system is connected with a communication circuit. It transmits/
receives data signals including request signals and response signals, and controls the system.

The display control unit transmits/receives data signals to/from each control unit with CAN communica-
tion. It performs an arithmetical operation on fuel information values by using data obtained from the con-
trol units, and then displays the calculated values on the screen.

The display control unit receives vehicle speed signals that are transmitted from the unified meter and A/
C amp., performs an arithmetical operation on drive information values, and then displays the calculated
values on the screen.

The images displayed on the monitor screen contain display control unit-generated RGB images, and rear
view images transmitted from the rear view camera control unit.

The display control unit controls image switching and image quality adjustments by communications with
the display.
REAR VIEW MONITOR

A rear view monitor was set to vehicle, which can check rearward on screen when backing up the vehicle.

For easier recognition of the vehicle width and the distance to the objects, the guide lines of distances and
rear are combined with the rear view image.

Image quality of the rear view image and of the RGB image can be adjusted separately.

INTEGRATED COLOR DISPLAY SYSTEM

Component DescriptionBKS0027K
DISPLAY CONTROL UNIT

Display control unit draws a status of the audio system and air
conditioner system, a TRIP screen, a FUEL ECONOMY screen,
etc., and transmits the image signals to the display screen.

It receives operation signals of audio system and air conditioner
system from A/C and AV switch, and transmits the operation sig-
nal of audio system to the audio unit through the communication
line and transmits the operation signal of air conditioner system
to the unified meter and A/C amp. through CAN communication.

Display signal from audio unit is transmitted to display control
unit through the communication line, and then the operating
state of the audio system is displayed in the screen.

Display signal from unified meter and A/C amp. is transmitted to
display control unit through the CAN communication, and then the operating state of the air conditioner
system is displayed in the screen.
DISPLAY

Images on the display include RGB image and rear view image
displayed when setting the select lever to R range.

Display control unit controls images on the display.
A/C AND AV SWITCH

A/C and AV switch, an integrated combination of audio system
and air conditioner system switches, are adopted.

Operation signal of audio system is transmitted to the audio unit
through display control unit with the communication line.

Operation signal of air conditioner system is transmitted to uni-
fied meter and A/C amp. through display control unit with CAN
communication.
REAR VIEW CAMERA

Rear view camera transmits rear view image signals to the dis-
play screen through the rear view camera control unit, when
reverse signal is input.

The rear view image is a mirror image reversed left and right
that is the same as seeing rear side with a room mirror.
