CONTROL OUTLINE
The combination meter reads the fuel level sensor signal from the fuel level sensor unit and indicates the fuel
level to the fuel gauge.
REFUEL CONTROL
The combination meter accelerates the fuel gauge segment if the all conditions listed below are met, or the
ignition switch is ON from OFF.
 Ignition switch is ON position.
 The vehicle is not moving.
 The fuel level change by 15 (3 - 1/4 lmp gal) or more.

DESCRIPTION
The combination meter incorporates a trip computer that displays the warning / information according to the
information received from various units.
PARKING BRAKE RELEASE WARNING
The combination meter indicates the parking brake release warning judged by the vehicle speed signal
received from the ABS actuator and electric unit (control unit) via CAN communication and the parking brake
switch signal from the parking brake switch.
Warning operation condition
Parking brake release warning is judged if all of the following conditions are fulfilled.
 Vehicle speed is 7 km/h (4.3 MPH) or higher
 Parking brake switch ON
D. Front bumper (left back) E. Engine room (LH) F. Behind the combination meter
G. Lower left side of rear seat
Unit Description
Combination meterControls the meter illumination according to the position light request signal transmitted from BCM
via CAN communication and the signal from illumination control switch integrated with the combi-
nation meter.
BCM Transmits the position light request signal to the combination meter via CAN communication.

METER SYSTEM
LOW FUEL WARNING
The combination meter indicates the low fuel warning judged by the fuel level sensor signal received from the
fuel level sensor unit.
Warning operation condition
 Fuel level: Approx. 11 (2 - 2/5 Imp gal) or less
DOOR/TRUNK OPEN WARNING
 The combination meter indicates the door open warning judged by each door switch signal received from the
BCM via CAN communication line.
 The combination meter indicates the trunk open warning judged by trunk switch signal received from the
BCM via CAN communication line.
INSTANTANEOUS FUEL CONSUMPTION
 The combination meter receives the fuel consumption monitor signal from the ECM and the vehicle speed
signal from the ABS actuator and electric unit (control unit) via CAN communication.
 The combination meter calculates instantaneous fuel consumption according to the fuel consumption moni-
tor signal and the vehicle speed signal received via CAN communication.
AVERAGE FUEL CONSUMPTION
 The combination meter receives the fuel consumption monitor signal from the ECM and the vehicle speed
signal from the ABS actuator and electric unit (control unit) via CAN communication.
 The combination meter calculates the average fuel consumption according to the fuel consumption monitor
signal and the vehicle speed signal received via CAN communication.
 The average fuel consumption displayed on the information display is uploaded in 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 miles) of driving.
AVERAGE VEHICLE SPEED
 The combination meter receives the vehicle speed signal from the ABS actuator and electric unit (control
unit) via CAN communication.
 Measures the time while the ignition switch is ON through the combination meter.
 The combination meter the average vehicle speed according to the above signals.
 The average vehicle speed displayed on the information display is uploaded in 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 miles) of driving.
TRAVEL TIME
Measures the time while the ignition switch is ON through the combination meter.
TRAVEL DISTANCE
 The combination meter receives the vehicle speed signal from the ABS actuator and electric unit (control
unit) via CAN communication.
 The combination meter calculates the vehicle distance according to the vehicle speed signal. The vehicle
distance is displayed.
POSSIBLE DRIVING DISTANCE
The combination meter 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 transmitted
from the fuel level sensor.
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 refueling with the ignition switch ON. Refer to MWI-
124, "INFORMATION DISPLAY : Description".
AMBIENT AIR TEMPERATURE
 The combination meter receives the ambient sensor signal from the ambient sensor.
 The combination meter calculates the ambient temperature according to the ambient sensor signal.
 The indicated temperature does not increase if the vehicle speed is less than 20 km/h (12 MPH).
