TACHOMETER
ECM provides engine speed signal to unified meter and A/C amp. with CAN communication line.
Unified meter and A/C amp. transmits engine speed signal to combination meter with communication line.
Combination meter indicates the engine speed according to engine speed signal.
WATER TEMPERATURE GAUGE
ECM provides engine coolant temperature signal to unified meter and A/C amp. with CAN communication
line.
Unified meter and A/C amp. transmits engine coolant temperature signal to combination meter with com-
munication line.
Combination meter indicates the engine coolant temperature according to engine coolant temperature
signal.
FUEL GAUGE
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 fuel level sensor unit and fuel pump (main) terminals 5 and 2, and
–through fuel level sensor unit (sub) terminals 2 and 1
–to unified meter and A/C amp. terminal 28.
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 fuel level signal.
ODO/TRIP METER
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 uses the vehicle speed signal (8-pulse) to calculate the mileage, and displays it.

TRIPLE METERS
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.
