• The combination meter inputs the information required to control the operation of information display by

using the communication signals and others from each unit.

• The combination meter integrates the drive computer function, and performs the warning display/information

display by using the signals received from each unit, sensor, and switch.

• When the enter switch signal or select switch signal is received, the combination meter can check, change

screens, perform setting, or reset the warning, indication, information, and setting on the information display.

INSTANTANEOUS FUEL CONSUMPTION

Control Outline

• The combination meter receives the fuel consumption monitor signal from ECM and the vehicle speed signal

from the ABS actuator control unit via CAN communication.

• Based on the fuel consumption monitor signal and vehicle speed signal that are received via CAN communi-

cation, the combination meter calculates the instantaneous fuel consumption, and displays the result.

VEHICLE SPEED

Control Outline

• The combination meter receives the vehicle speed signal from the ABS actuator and electric unit (control

unit) via CAN communication.

• Based on the vehicle speed signal received via CAN communication, the combination meter displays the

vehicle speed.

CRUISE CONTROL SYSTEM STATUS

Control Outline

• The combination meter receives the ASCD status signal from ECM via CAN communication.
• Based on the ASCD status signal received via CAN communication, the combination meter displays the

CRUISE control system setting status.
NOTE:
When the CRUISE control system is OFF, the CRUISE control system status is not displayed.

AVERAGE FUEL CONSUMPTION

Control Outline

• The combination meter receives the fuel consumption monitor signal from ECM and the vehicle speed signal

from the ABS actuator control unit via CAN communication.

• Based on the fuel consumption monitor signal and vehicle speed signal that are received via CAN communi-

cation, the combination meter calculates the average fuel consumption, and displays the result.

• The average fuel consumption displayed on the information display is updated at approximately 30-second

intervals.

NOTE:
“

−−−−

” is displayed for approximately 30 seconds just after the reset operation and after the ignition switch is

OFF

→

ON. It is displayed simultaneously until the vehicle is driven approximately 500 m (0.3 mile).

AVERAGE VEHICLE SPEED

Control Outline

• The combination meter receives the vehicle speed signal from the ABS actuator and electric unit (control

unit) via CAN communication.

• Based on the vehicle speed signal received via CAN communication and on the travel time measured in

combination meter, the combination meter calculates the average vehicle speed, and displays the result.

• The average vehicle speed displayed on the information display is updated at approximately 30-second

intervals.

NOTE:
“

−−−−

” is displayed for 30 seconds just after the reset operation and after the ignition switch is OFF

→

ON. It is

displayed simultaneously until the vehicle is driven approximately 500 m (0.3 mile).

TRAVEL TIME

Control Outline

The combination meter measures and displays travel time (ignition switch ON time).

TRAVEL DISTANCE

Control Outline

MWI-28

< SYSTEM DESCRIPTION >

METER SYSTEM

The combination meter receives the vehicle speed signal from the ABS actuator and electric unit (control unit)
via CAN communication, then calculates and displays the travel distance.

POSSIBLE DRIVING DISTANCE

Control Outline

• The combination meter receives the fuel consumption monitor signal from ECM and the vehicle speed signal

from the ABS actuator control unit via CAN communication.

• Based on the signal received via CAN communication and on the fuel level sensor signal received from the

fuel level sensor unit, the combination meter calculates the possible driving distance, and displays the result.

NOTE:
• “

−−−−

” is displayed for 30 seconds after the ignition switch is OFF

→

ON. It is displayed simultaneously until

the vehicle is driven approximately 500 m (0.3 mile).

• The indicated values may not match each other when refueling with the ignition switch ON. Refer to

MWI-16,

"FUEL GAUGE : System Description"

.

AMBIENT AIR TEMPERATURE

• Combination meter calculates outside air temperature based on the signal received from ambient sensor,

and displays the result on information display.

• Combination meter corrects the indicated temperature using ignition switch signal, ambient sensor signal

and vehicle speed signal.

Correction Process (Right after ignition switch is turned ON)

The detected temperature by ambient sensor is displayed when the vehicle enters in both of the following con-
dition.
• When the detected temperature is higher than the indicated temperature on information display.
• When the duration of ignition switch OFF to ON is long.
The last indicated temperature is displayed when the vehicle enters in either of the following conditions.
• When the detected temperature by ambient sensor is lower than the indicated temperature on information

display.

• When the duration of ignition switch OFF to ON is short.

Correction Process (When the ignition switch is ON)

The detected temperature by ambient sensor is displayed under the following condition.
• When the detected temperature is lower than the indicated temperature on information display.
The indicated temperature is not updated under the following condition.
• When the detected temperature by ambient sensor is higher than the indicated temperature on information

display [at a speed of 20 km/h (12 MPH) or less].

The indicated temperature on information display rises slowly to reach the detected temperature by ambient
sensor under the following condition.
• When the detected temperature is higher than the indicated temperature on information display [at a speed

of more than 20 km/h (12 MPH)].

The indicated temperature on information display rises to reach the detected temperature by ambient sensor
under the following condition.
• When the detected temperature is higher than the indicated temperature on information display [while driv-

ing a certain period of time at a speed of more than 20 km/h (12 MPH)].

NOTE:
• “

−−−−

” is displayed for 2.5 seconds right after ignition switch is turned ON.

• If a battery or combination meter is removed and installed, the detected temperature by ambient sensor is

displayed, right after ignition switch is turned ON.

• The indicated temperature may be higher than the actual temperature because of heat radiation from engine

or reflection of heat on road surface.

METER SYSTEM

When the following conditions are satisfied, the combination meter reads the resistance value of oil level sen-
sor, and displays the oil level on the information display. The combination meter does not read the oil level
sensor resistance value within 5 minutes after the previous reading of oil level sensor resistance value by the
combination meter.
1.

Turn the ignition switch OFF.

2.

Wait for 5 minutes or more, then open the driver door.
