[INTEGRATED CONTROL SYSTEM]

Fuel ECO display characteristic

G-Force

The G-FORCE gauge displays the decel G level and side G level in
3 grades respectively, which are calculated based on the decel G
sensor signal and side G sensor signal received from the ABS actu-
ator and electric unit (control unit) via CAN communication.

Drive Information

The travel time, average speed, and mileage are displayed as fol-
lows.
• Travel time: Displays the time calculated by the multi display unit.
• Average speed: Calculated from the odometer signal and vehicle

speed signal received from the combination meter via CAN com-
munication.

• Mileage: Calculated from the odometer signal and vehicle speed

signal received from the combination meter via CAN communica-
tion.

ECO Information

The fuel economy record is calculated from the fuel consumption
monitor signal received from ECM via CAN communication and the
vehicle speed signal received from the combination meter via CAN
communication.

• The engine torque, engine power, boost, and instantaneous fuel consumption are provided for information

purposes only. They are not intended to prompt the driver to adjust driving style. The readings may be
slightly delayed relative to the actual vehicle behaviors. This is not a malfunction.

• The voltmeter reading cannot be used as an indicator for battery replacement because it indicates the input

voltage to the multi display unit, not the battery voltage.

• The SET UP screen are viewable and operable only while the vehicle is stopped.
• The ECO information screen is operable only while the vehicle is stopped.
• If no time setting is performed, the daily and weekly fuel consumption history data are not displayed.
• The readings may differ from the actual values depending on driving conditions.

DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000007578006

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-board mul-
tiplex communication line with high data communication speed and excellent error detection ability. A modern
vehicle is equipped with many ECUs, and each control unit shares information and links with other control
units during operation (not independent). In CAN communication, 2 control units are connected with 2 commu-
nication lines (CAN-L-line and CAN-H-line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
Refer to

LAN-28, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"

for details of the

communication signal.
