UNIFIED METER CONTROL UNIT
Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.
Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.
Digital meter is adopted for odo/trip meter.
NOTE:
The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter
is erased when the battery cable is disconnected.
Dot matrix LCD is adopted to display “push engine starter”, “A/T position” and “ICC system* ”.
Odo/trip meter and dot matrix LCD segments can be checked in self-diagnosis mode.
Meters/gauges can be checked in self-diagnosis mode.
*: With ICC system
UNIFIED METER AND A/C AMP.
Refer to DI-28, "COMBINATION METER CONTROL FUNCTION" in “UNIFIED METER AND A/C AMP”.
POWER SUPPLY AND GROUND CIRCUIT
Power is supplied at all times
through 10A fuse [No. 21, located in the fuse block (J/B)]
to combination meter terminal 23,
through 10A fuse [No. 19, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 54.
With the ignition switch in the ACC or ON position, power is supplied
through 10A fuse [No. 6, located in the fuse block (J/B)],
to combination meter terminal 2, and
to unified meter and A/C amp. terminal 41.
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 12,
through 10A fuse [No. 12, located in the fuse block (J/B)]
to unified meter and A/C amp. terminal 53.
Ground is supplied
to combination meter terminals 9, 10 and 11
to unified meter and A/C amp. terminals 55 and 71
through grounds M16 and M70.

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”.)
