INTEGRATED DISPLAY SYSTEMPFP:28090
System DescriptionBKS0021Y
For system operation information, refer to Owner's Manual.
INTEGRATED DISPLAY SYSTEM

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

The display 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.
Component DescriptionBKS002D1
DISPLAY UNIT

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 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 unit through the CAN communication, and then the oper-
ating state of the air conditioner system is displayed in the
screen.
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 unit with the communication line.

Operation signal of air conditioner system is transmitted to uni-
fied meter and A/C amp. through display unit with CAN commu-
nication.

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.

Prior to performing trouble diagnosis, make sure there are no corresponding description in the “Example of
Symptoms Possible No Malfunction”. Refer to AV- 111 , "
Example of Symptoms Possible No Malfunction" .
A/C and AV Switch Self-Diagnosis FunctionBKS00280
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.

Continuity of the switches by sounding the buzzer when pressing the rear audio control 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.)
