SPEEDOMETER
ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C amp.
with CAN communication line. After unified meter and A/C amp. received the vehicle speed signal, it changes
the signal to 8 pulse signal and provides the 8 pulse signal to the combination meter for the speedometer.
TACHOMETER
The tachometer indicates engine speed in revolutions per minute (rpm).
ECM provides an engine speed signal to unified meter and A/C amp. with CAN communication line. Unified
meter and A/C amp. provides an engine speed signal to combination meter for tachometer with communica-
tion line between unified meter and A/C amp. and combination meter.
LOW WATER TEMPERATURE INDICATOR LAMP, HIGH WATER TEMPERATURE WARNING
LAMP
ECM converts water temperature signal from water temperature sensor into data and transmits the data to uni-
fied meter and A/C amp. with CAN communication line. Unified meter and A/C amp. transmit the received
water temperature signal to the combination meter with communication line between unified meter and A/C
amp. and combination meter. Combination meter turns on/off low water temperature indicator lamp or high
water temperature warning lamp through the received water temperature signal.
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 36

through the fuel level sensor unit and fuel pump terminals 5 and 2

to unified meter and A/C amp. terminal 28 for the fuel gauge.
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.

OK >> GO TO 4.
NG >> Check battery power supply of combinatiom meter and ground circuit.
4. CHECK COMBINATION METER CIRCUIT
Check indication of each meter/gauge in self-diagnosis mode.
OK or NG
OK >> GO TO 5
NG >> Replace combination meter.
5. CHECK LOW-FUEL WARNING LAMP ILLUMINATION
While checking low-fuel warning lamp check, confirm illumination of low-fuel warning lamp.
Does low
-fuel warning lamp illuminate (while not pushing odo/trip meter switch)?
YES >> GO TO 6.
NO >> Replace combination meter.
Condition of odo/trip meter switch Low-fuel warning lamp
