System DescriptionEKS00I05
UNIFIED METER CONTROL UNIT
Speedometer, odo/trip meter, tachometer and fuel gauge are controlled by the unified meter control unit,
which is built into the combination meter.
Warning and indicator lamps are controlled by signals drawn from the CAN communication system, BCM
(body control module), and components connected directly to the combination meter.
Odo/trip meter and A/T indicator (with A/T) or CVT indicator (with CVT) segments can be checked in self-
diagnosis mode.
Meters/gauges can be checked in self-diagnosis mode.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
through 10A fuse [No. 13, located in the fuse block (J/B)]
to combination meter terminal 27.
With the ignition switch in the ON or START position, power is supplied
through 10A fuse [No. 14, located in the fuse block (J/B)]
to combination meter terminal 28.
Ground is supplied
to combination meter terminals 21, 22 and 23

through grounds M57 and M61.
SPEEDOMETER
With ABS
The ABS actuator and electric unit (control unit) provides a vehicle speed signal to the combination meter via
CAN communication lines.
Without ABS or CVT
The vehicle speed sensor provides a vehicle speed signal to the combination meter for speedometer indica-
tion.
With CVT, Without ABS
The TCM provides a vehicle speed signal to the combination meter via CAN communication lines.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm). The ECM provides an engine speed
signal to combination meter via CAN communication lines.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by the unified meter control unit and a variable resistor signal supplied
to combination meter terminal 24
through fuel level sensor unit and fuel pump terminal 5
through fuel level sensor unit and fuel pump terminal 2
from combination meter terminal 6.
ODO/TRIP METER
The vehicle speed signal and the memory signals from the meter memory circuit are processed by the combi-
nation meter and the mileage is displayed.
How to Change the Display
Refer to Owner's Manual for odo/trip meter operating instructions.
CAN COMMUNICATION SYSTEM DESCRIPTION
Refer to LAN-4, "SYSTEM DESCRIPTION" .
