COMBINATION METERSPFP:24814
System DescriptionNKS0005S
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 a
signals 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 and A/T indicator 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-44, "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 24.
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 23.
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 14.
Ground is supplied

to combination meter terminals 10, 11 and 12

through body grounds M30 and M66.
SPEEDOMETER

VDC/TCS/ABS control unit [with VDC] or ABS actuator and electric unit (control unit) [without VDC] pro-
vides a vehicle speed signal to the unified meter and A/C amp. with CAN communication line.

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 indicates the vehicle speed according to vehicle speed signal (8-pulse).

Revision: 2006 November2007 350Z
TRIPLE METERSPFP:24845
System DescriptionNKS0006F
TRIPLE METER

Oil pressure gauge and voltmeter are controlled by the triple
meter.

Trip computer is controlled by the signals from the unified meter
and A/C amp.

Triple meter operation can be checked with self-diagnosis mode
of combination meter.
UNIFIED METER AND A/C AMP.
Refer to DI-45, "TRIPLE 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 triple meter terminal 2.
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 triple meter terminal 3.
Ground is supplied

to triple meter terminal 1

through grounds M30 and M66.
VOLTMETER
When ignition switch is turned to the ON position, the voltmeter indicates the battery voltage.
OIL PRESSURE GAUGE
With the ignition switch in the ON or START position, power is supplied

through triple meter terminal 9

to oil pressure sensor terminal 1.
Ground is supplied

to triple meter terminal 7

through oil pressure sensor terminal 3.
And triple meter reads oil pressure signal from oil pressure sensor

from oil pressure sensor terminal 2

to triple meter terminal 8.
NOTE:

Triple meter judges an oil pressure condition by oil pressure signal, and transmits oil pressure warning
lamp signal to combination meter through unified meter and A/C amp. with communication line.

Oil pressure gauge is not designed to indicate the low oil level. Use the oil level gauge to check the oil
level.
