System Description

INFOID:0000000001328710

For system operation information, refer to Owner's Manual.

INTEGRATED 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 communication. It

performs 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 control unit receives door switch signals from the BCM with CAN communication, and displays a

warning on the screen when driving over the set speed with a door half-shut.

• 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 val-
ues on the screen.

• The images displayed on the monitor screen contain display control unit-generated RGB images.
• The display control unit controls image switching and image quality adjustments by communications with the

display.

• Display control unit draws a status of the audio and air conditioner,

a TRIP screen, a FUEL ECONOMY screen, etc., and transmits the
image signals to the display screen.

• It receives operation signals of audio and air conditioner from A/C

and AV switch, and transmits the operation signal of audio to the
audio unit via the communication line and transmits the operation
signal of air conditioner to the meter and A/C amp. via CAN com-
munication.

DISPLAY

• Images on the display include RGB image such as map screen.
• Display control unit controls images on the display.

A/C AND AV SWITCH

• A/C and AV switch, an integrated combination of audio and air con-

ditioner switches, are adopted.

• Operation signal of audio is transmitted to the audio unit through

display control unit with the communication line. Operation signal
of air conditioner is transmitted to meter and A/C amp. through dis-
play control unit with CAN communication.
