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

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.

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".

SELF-DIAGNOSIS MODE
 Information display LCD segment operation can be checked in self-diagnosis mode.
 Meters/gauges can be checked in self-diagnosis mode.
OPERATION PROCEDURE
1. Turn ignition switch ON, and switch the trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with “trip A” displayed, the mileage on “trip A” is reset to “0000.0”.
(The same way for “trip B”.)
2. Turn ignition switch OFF.
3. While pressing the trip reset switch (1), turn ignition switch ON
again.
4. Make sure that the trip meter displays “0000.0”.
5. Press the trip reset switch at least 3 times. (Within 7 seconds
after the ignition switch is turned ON.)
6. The unified meter control unit is turned to self-diagnosis mode.
 The segment dots of the information display LCD (1) blink
alternately.
 Water temperature gauge and fuel gauge return to zero, simul-
taneously.
NOTE:
 Check combination meter power supply and ground circuit when the self-diagnosis mode of the combi-
nation meter does not start. Replace combination meter if abnormal.
 If any of the segments are not displayed, replace combination meter.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000003792552
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detectability. Many
electronic control units are equipped onto vehicles, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with two communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with
less wiring. Each control unit transmits/receives data but selectively reads required data only.

How to Use CAN Communication Signal Chart".
