ECO INDICATOR : System Description

INFOID:0000000010122395

SYSTEM DIAGRAM

DESCRIPTION

• The following ECO drive levels can be checked on the ECO indicator of upper meter:

- Instant ECO drive level

- Cumulative ECO drive level

• VCM sends the signals below to the combination meter via CAN communication:

- Instant ECO indicator signal

- ECO tree signal

• The combination meter sends the signals it received via CAN communication from VCM to the upper meter.

• Based on the signals received via the communication line, the upper meter indicates the ECO drive level on

the ECO indicator.

Instant ECO indicator

Indicates the instantaneous ECO drive 
level based on the driving conditions.

Instant ECO indicator signal

ECO tree

Totals the instantaneous ECO drive lev-
els and indicates the cumulative ECO 
drive level during driving (from power 
switch READY to OFF).

ECO tree signal

< SYSTEM DESCRIPTION >

SYSTEM

• The cumulative instant ECO indicator (1) results are displayed in

the ECO tree (2).

• When all ECO tree (2) segments are ON, ECO tree (3) turns ON

(all segments) and ECO tree (2) turns OFF.

• The cumulative instant ECO indicator (1) results are again dis-

played in the ECO tree (2).

• When all ECO tree (2) segments are ON, ECO tree (4), ECO tree

(5), and ECO tree (6) turn ON in sequence.

• Based on the signals received via CAN communication from VCM,

the combination meter displays the driving range on the driving

range display (1). 

Driving Range Display Pattern

NOTE:

• If the power switch is turned from OFF to READY, the value that is last received is displayed.

• The driving range is updated approximately every 0.06 mile (100 m) of driving.

OUTSIDE AIR TEMPERATURE DISPLAY
OUTSIDE AIR TEMPERATURE DISPLAY : System Description

INFOID:0000000010122397

SYSTEM DIAGRAM

DESCRIPTION

• VCM transmits a ambient sensor signal to the combination meter via CAN communication.

• ABS actuator and electric unit (control unit) transmits a vehicle speed signal to the combination meter via

CAN communication.

• The combination meter calculates the outside air temperature based on the signals received from VCM and

ABS actuator and electric unit (control unit) via CAN communication.

• The combination meter sends the calculated outside air temperature signal to the upper meter via the com-

munications line.

SYSTEM

• The upper meter indicates the outside air temperature according to the outside air temperature signal

received from the combination meter by means of communication line.

• For outside temp (Alert), refer to 

MWI-35, "INFORMATION DISPLAY : System Description"

.

NOTE:

• The indicated temperature is corrected based on a power switch signal, ambient temperature detected by

the ambient sensor, and vehicle speed signal. The indicated temperature is not raised under vehicle speed

less than 20 km/h (12 MPH).

• The ambient sensor input value that is displayed on “Data Monitor” of CONSULT is the value before the cor-

rection. It may not match the indicated temperature on the outside air temperature display.

• Depending on motor heat or heat on the road surfaces, an ambient temperature may be indicated higher

than actual one.

SYSTEM DIAGRAM

DESCRIPTION

• Time for timer charge and A/C-Heater Timer (Climate Ctrl. Timer) can be set from the information display

setting screen. 

• The combination meter transmits the (manually set) clock signal to VCM via CAN communication and com-

pensates the VCM current time. 

Timer Charge Function

• Timer charge stop time can be set on the settings screen of the information display. For the setting method,

refer to 

MWI-35, "INFORMATION DISPLAY : System Description"

.

• After the power switch is turned OFF, VCM starts at a set charge start time. (The time of the timer function is

controlled by VCM.) 

• VCM starts, and then charge starts. For details of the charging function, refer to 

EVC-51, "LI-ION BATTERY

CHARGE CONTROL : System Description"

.

• Charge is completed. 

A/C-Heater Timer (Climate Ctrl. Timer) Function 

• Estimated time of departure can be set on the settings screen of the information display. For the setting

method, refer to
