System Description

The multi display unit receives necessary information for controlling the following functions from the respective units via CAN communication.
- D-MODE function
- Information display/setting
- Air conditioner adjustment function. Refer to "SYSTEM DESCRIPTION ".
The multi display unit transmits the status of user-selected D-MODE (NORMAL, SPORT, or ECO) to the TCM (CVT models), ECM (M/T models), EPS control unit and A/C auto amp. For the D-MODE functions, refer to "SYSTEM DESCRIPTION ".
TCM transmits to ECM the D-MODE status (NORMAL, SPORT, or ECO) received from the multi display unit (CVT models).
ECM (M/T models) and EPS control unit receives the D-MODE status (NORMAL, SPORT, or ECO) from the multi display unit.
The A/C auto amp. receives the air conditioner switch operation signal, ECO mode signal, and ECO mode switch signal from the multi display unit.
The multi display unit integrates a diagnosis function that allows a diagnosis by CONSULT.

Display/operation restrictions

To secure safety, some functions are not allowed for user operation during driving.
The functions subject to the display/operation restriction are as follows.

Function		Condition	Control content
ECO information (Fuel Economy Record)	Daily Reset, Weekly Reset, Reset at Start, and Manual Reset	Driving	Cannot be operated (Reset, scroll)
ECO information (Fuel Economy Record)	Daily Reset, and Weekly Reset	When no time is set	Fuel consumption history is not displayed (Warning message appears)
SET UP		Driving	Item selection and setting are not available No display

Driving status judgment criterion

The driving status is judged from the vehicle speed signal received from the combination meter via CAN communication. The driving status is displayed on the multi display unit and operation restrictions are applied as necessary.
