COMBINATION METERSPFP:24814
System DescriptionNKS002ZC
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.

Odo/trip meter, shift position indicator and ICC system display segments can be checked in self-diagnosis
mode.

Meters/gauges can be checked in self-diagnosis mode.
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. 19, located in the fuse block (J/B)]

to combination meter terminal 8, and

to unified meter and A/C amp. terminal 21.
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 7,

through 10A fuse [No. 12, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 22.
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 4,

through 15A fuse [No. 10, located in the fuse block (J/B)], and

through 15A fuse [No. 11, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 46.
Ground is supplied

to combination meter terminals 5, 6 and 15

through grounds M35, M45 and M85,

to unified meter and A/C amp. terminals 29 and 30

through grounds M35, M45 and M85.

FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.

Unified meter and A/C amp. reads a resistor signal from fuel level sensor.
Signal is supplied
–from unified meter and A/C amp. terminal 36
–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 28 for the fuel gauge.

Unified meter and A/C amp. provides a fuel level signal to combination meter with communication line.

Combination meter indicates the approximate fuel level according to the fuel level signal.
ODO/TRIP METER

ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C
amp. with CAN communication.

Unified meter and A/C amp. converts the vehicle speed signal to the 8-pulse signal, and outputs the vehi-
cle speed signal (8-pulse) to combination meter.

Combination meter uses the vehicle speed signal (8-pulse) to calculate the mileage, and displays it.
How to Change The Display For Odo/trip Meter
Switch modes with following procedure.

When trip transfer switch is pressed, trip meter display changes.

If trip reset switch is pressed for 1 second or more while “trip A”
is displayed, only “trip A” is reset.
NOTE:
The record of the odo meter is kept even if the battery cable is dis-
connected. The record of the trip meter is erased when the battery
cable is disconnected.
