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.

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.

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,
