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.

UNIFIED METER AND A/C AMP
Revision: 2006 November2007 350Z
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionNKS0006X
DESCRIPTION

For the unified meter and A/C amp., the signal required for con-
trolling the combination meter and triple meter are integrated in
the A/C auto amp.

Unified meter and A/C amp. corresponds a CONSULT-III func-
tion (self-diagnosis results, CAN diagnosis support monitor and
data monitor).
COMBINATION METER CONTROL FUNCTION

Unified meter and A/C amp. receives necessary information for combination meter from each unit.

Unified meter and A/C amp. converses with the combination meter transmits a signal through with com-
munication line (TX, RX) between unified meter and A/C amp. and combination meter.
Input/output signals between unified meter and A/C amp. and combination meter.
NOTE:
Combination meter performs fail-safe operation when unified meter and A/C amp. communication is malfunctioning. Refer to DI-7,
"FAIL-SAFE" .
