DESCRIPTION

• The combination meter retrieves the information required for controlling the operations of the information

display from BCM with the CAN communication lines.

• The combination meter incorporates a trip computer that displays the information according to the signal

received from various units.

MAINTENANCE

The remaining distance from the set maintenance distance is displayed.

OIL LEVEL

The combination meter displays it judged with the oil level signal received from the oil level sensor.

CLOCK

Clock displays the time measured in the combination meter.

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 and electric unit (control unit) via CAN communication.

• The combination meter indicates the average fuel consumption calculated by the signal received.
• The average fuel consumption displayed on the information display is uploaded at approximately 30-second

intervals.

AVERAGE VEHICLE SPEED

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

unit) with the CAN communication line.

• The combination meter indicates the average vehicle speed according to the vehicle speed signal received

and the time measured in the combination meter.

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

intervals.

TRAVEL TIME

Control Outline

Measures the driving time (ignition switch ON time) in the combination meter and displays it.

Control Outline

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

unit) with the CAN communication line.

• The combination meter indicates the travel distance calculated by the vehicle speed signal received.

POSSIBLE DRIVING DISTANCE

• Combination meter receives the fuel consumption signals from ECM and the vehicle speed signals from

ABS actuator and electric unit (control unit) with the CAN communication line.

• Combination meter calculates the possible driving distance from the signals through CAN communication

line and the fuel level signals from the fuel level sensor to display.

AMBIENT AIR TEMPERATURE

• The combination meter indicates the ambient temperature calculated by the OAT sensor signal received

from the OAT sensor.

• The indicated temperature is corrected by the ignition switch signal, the OAT sensor detection temperature,

and the vehicle speed signal. It does not increase if the vehicle speed is less than 20 km/h (12.4 MPH).

• It switches the ambient temperature to the blinking display when the ambient temperature 3

°

C (37

°

F) or less

continues for 20 seconds or more (road ice warning).

Correction Process (Ignition Switch OFF

→

ON)

The OAT sensor detection temperature is not displayed in real time if all of the following conditions are fulfilled. The indicated
temperature before the ignition switch OFF is displayed.

• The ignition switch OFF time is less than 3.5 hours.
• The OAT sensor detection temperature is higher than the indicated temperature before the ignition switch

OFF.

Correction Process (Ignition Switch ON)

Perform the following correction if the OAT sensor detection temperature is higher than the indicated temperature when the vehi-
cle speed is 20 km/h (12.4 MPH) or more.

• Shorten the update time of the indicated temperature according to the increase of the vehicle speed.

DIAGNOSIS SYSTEM (METER)

Diagnosis Description

INFOID:0000000000892285

ON BOARD DIAGNOSIS

The combination meter can be checked on the following items with the on board diagnosis function.
• Check the segment of information display
• Check the operations of speedometer and tachometer
• Check error code
• Check the warning lamp/indicator lamp for illumination

START-UP PROCEDURE OF ON BOARD DIAGNOSIS

1.

Turn the ignition switch ON.

2.

Turn the ignition switch OFF after setting the display to trip A or

B with the

switch (1).

3.

Turn the ignition switch to ON while pressing the

switch.

4.

Press the

switch at least 3 times (within 7 seconds after the

ignition switch is turned ON).

5.

The combination meter self-diagnosis mode starts.

6.

Press the

switch to go to the next step.

NOTE:
Check the combination meter power supply and the ground circuit if the on board diagnosis does not start.
Refer to

MWI-28, "COMBINATION METER : Diagnosis Procedure"

.
