SHIFT-UP INDICATOR

Shift-up indicator can be used when shifting up at a constant
engine speed from any gear while driving. It becomes a guide
for shift-up timing.

Shift-up indicator flashes approximately 500 rpm before reach-
ing the engine speed set. It illuminates when reaching the
engine speed set.
Shift-up engine speed can be set by the shift-up indicator setting
mode on trip computer. Refer to DI-29, "
Shift-up Indicator Setting
Mode" .
NOTE:

There may be a time lag between the shift-up indicator illumina-
tion and the tachometer indication.

If the battery cable is disconnected, the set engine speed becomes 7,000 rpm.

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.

Self-Diagnosis Mode of Triple MeterNKS0006L
SELF-DIAGNOSIS FUNCTION
Triple meter operation can be checked with self-diagnosis mode of combination meter.
OPERATION PROCEDURE
1. While pressing the odo/trip meter switch, turn ignition switch ON.
2. Make sure that the trip meter displays “0000.0”.
3. Press the odo/trip meter switch at least 3 times (within 7 seconds after the ignition switch is turned ON).
4. All the segments on the trip computer illuminate. At this time, the triple meter is turned to self-diagnosis
mode.
NOTE:
If any of the segments is not displayed, replace triple meter.
5. Press the odo/trip meter switch. voltmeter and oil pressure
gauge should indicate as shown in the figure while pressing odo/
trip meter switch.
NOTE:
If voltmeter or oil pressure gauge is not activated, replace triple
meter.

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" .
