SPEEDOMETER
The speedometer indicates the vehicle speed.
ABS actuator and electric unit (control unit) converses a pulse signal from wheel sensor to vehicle speed
signal, and transmit vehicle speed signal to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. transmits vehicle speed signal to combination meter with communication line.
Combination meter converses vehicle speed signal to the angle signal, and commands to speedometer.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM converses a signal from crankshaft position sensor to engine speed signal, and transmits to unified
meter and A/C amp. with CAN communication.
Unified meter and A/C amp. transmits engine speed signal to combination meter with communication line.
Combination meter converses engine speed signal to the angle signal, and commands to tachometer.
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM converses a signal from engine coolant temperature sensor to engine coolant temperature signal,
and transmits to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. transmits engine coolant temperature signal to combination meter with com-
munication line.
Combination meter converses engine coolant temperature signal to the angle signal, and commands to
water temperature gauge.

FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable ground signal supplied
from unified meter and A/C amp. terminal 58
through the fuel level sensor unit and fuel pump (main) terminals 5 and 2, and
through the fuel level sensor unit (sub) terminals 2 and 1
to unified meter and A/C amp. terminal 42.
Unified meter and A/C amp. provides a fuel level signal to combination meter for fuel gauge with communica-
tion line between unified meter and A/C amp. and combination meter.
ODO/TRIP METER
ABS actuator and electric unit (control unit) converses a pulse signal from wheel sensor to vehicle speed
signal, and transmits vehicle speed signal to unified meter and A/C amp. with CAN communication.
Unified meter and A/C amp. converses vehicle speed signal to 8 pulse signal, and transmits to combina-
tion meter.
Combination meter processes the 8 pulse signal and the memory signals from the meter memory circuit.
Then the mileage is displayed.
How to Change The Display For Odo/trip Meter
Operating the odo/trip meter switch allows switching the mode in the following order.
The odo/trip meter display switching and trip display resetting
can be identified by the time from pressing the odo/trip meter
switch (1) to releasing it.
When resetting with “trip A” displayed, only “trip A” display is
reset. (The same way for “trip B”.)

METER ILLUMINATION CONTROL
Meter illumination* is controlled by the unified meter control unit.
Ring illumination under normal operation and engine start excitement function can be turned ON/OFF with
pressing meter illumination control switch for more than 1 second.
*: Illumination for ring, meter face, pointer, dot matrix LCD and odo/trip meter
Daytime Mode
Meter illumination is adjusted to 5 steps by meter illumination control
switch (1) in daytime mode.
Nighttime Mode
Combination meter is transferred to nighttime mode with position light request signal from BCM with CAN
communication.
Meter illumination is adjusted to 16 steps by illumination control
switch (1) in nighttime. Refer to LT- 2 9 3 , "
ILLUMINATION" .
Driver Welcome Function
Ring illumination gradually turns ON when a driver gets in the vehicle with intelligent key and closes the driver
side door.
NOTE:
Ring illumination gradually turns OFF when not turning the ignition switch ON at a certain period of time.
Engine Start Excitement Function
Combination meter detects the engine start when input engine speed signal at first. Pointers of speed meter
and tachometer sweep and ring illumination gradually turns ON when combination meter detects the engine
start. Then, combination meter starts the normal control.
NOTE:
Water temperature gauge and fuel gauge do not function.
Engine start excitement function can be turned ON/OFF with pressing meter illumination control switch for
more than 1 second.
