• The unified meter and A/C amp. receives the vehicle speed signal from the ABS actuator and electric unit

(control unit) via CAN communication line.

• Measures the time during the ignition switch ON with the unified meter and A/C amp.
• The unified meter and A/C amp. calculates the average vehicle speed according to the above signals. These

signals are transmitted to the combination meter with the communication line.

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

intervals.

NOTE:
When turning ON the ignition switch after triggering a reset or removing/installing the battery, “

−−−−

” is indi-

cated until 30 seconds/500 m (0.31 mile) of driving.

TRAVEL TIME

Measures the time during the ignition switch ON with the unified meter and A/C amp, and transmits it to the
combination meter by means of communication line.

TRAVEL DISTANCE

• The unified meter and A/C amp. transmits the vehicle speed signal from ABS actuator and electric unit (con-

trol unit) to the combination meter.

• The combination meter calculates the vehicle distance according to the vehicle speed signal. The vehicle

distance is displayed.

POSSIBLE DRIVING DISTANCE

The unified meter and A/C amp. calculates possible driving distance according to the vehicle speed signal and
fuel consumption monitor signal transmitted via CAN communication and the fuel level sensor signal transmit-
ted from the fuel level sensor. These signals are transmitted to the combination meter with the communication
line.
NOTE:
• When turning ON the ignition switch after removing/installing the battery, “

−−−−

” is indicated until 30 sec-

onds.

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

MWI-143, "INFORMATION DISPLAY : Description"

.

AMBIENT AIR TEMPERATURE

• The unified meter and A/C amp. receives the ambient sensor signal from the ambient sensor.
• The unified meter and A/C amp. calculates the ambient temperature according to the ambient sensor signal,

and transmits it to the combination meter.

• The indicated temperature does not increase if the vehicle speed is less than 20 km/h (12 MPH).
NOTE:
• The ambient sensor input value that is displayed on “Data Monitor” of CONSULT-III is the value before the

correction. It may not match the indicated temperature on the information display.

• Ambient temperature may be indicated higher than an actual temperature, depending on heat in the engine,

a road surface temperature, and so on.
