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.

How to Change The Display
Pressing the odo/trip meter switch toggles the display mode in the following order.

The odo/trip meter display mode toggling and trip display resetting can be identified by the time elapsed
from pressing the odo/trip meter switch to releasing it.

When resetting with “trip A” displayed, only “trip A” is reset. (The “trip B” functions in the same way.)
NOTE:
The record of the odo meter is kept even if the battery cable is disconnected. The record of the trip meter is
erased when the battery cable is disconnected.
ILLUMINATION CONTROL
Daytime Mode
When ignition switch is turned ON, combination meter and triple meter illumination is turned ON by unified
meter control unit.
Nighttime Mode

Unified meter control unit is transferred to nighttime mode, with ignition switch turned ON and position
light request signal from BCM with CAN communication.

When in nighttime mode, trip computer switch, and illumination control switch illumination turns ON by
unified meter control unit. Each illumination is controlled by unified meter control unit.

Each illumination can be adjusted to 16 step by illumination con-
trol switch in nighttime mode.
NOTE:
For further details of illumination circuit, refer to LT- 1 5 6 , "

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.

Self-Diagnosis Mode of Combination MeterNKS0005Z
SELF-DIAGNOSIS FUNCTION

Odo/trip meter segment and A/T indicator segment operation can be checked in self-diagnosis mode.

Meters/gauges can be checked in self-diagnosis mode.
OPERATION PROCEDURE
1. Turn ignition switch ON, and switch the odo/trip meter to “trip A” or “trip B”.
NOTE:
If the diagnosis function is activated with “trip A” displayed, the mileage on “trip A” will indicate “0000.0”,
but the actual trip mileage will be retained. (The “trip B” functions in the same way.)
2. Turn ignition switch OFF.
3. While pressing the odo/trip meter switch, turn ignition switch ON again.
4. Make sure that the trip meter displays “0000.0”.
5. Press the odo/trip meter switch at least 3 times (within 7 seconds after the ignition switch is turned ON).
6. All the segments on the odo/trip meter and A/T indicator illuminate, and simultaneously the low-fuel warn-
ing lamp indicator illuminates. At this time, the unified meter control unit is turned to diagnosis mode.
NOTE:

Check combination meter power supply and ground circuit when self-diagnosis mode of combination
meter does not start. Replace combination meter if normal.

If any of the segments is not displayed, replace combination meter.
7. Press the odo/trip meter switch. Each meter/gauge should indi-
cate as shown in the figure while pressing odo/trip meter switch.
(At this time, the low-fuel warning lamp goes off).
NOTE:
If any of the meter/gauge is not activated, replace combination
meter.

When the ignition switch is turned ON, the display scrolls all the modes. And then shows the mode chosen
before the ignition switch is turned OFF.

Trip computer is operated by the trip computer switch.

Trip computer receives a switch signal from combination meter
through the unified meter and A/C amp. with communication
line.
The mode of the trip computer is the following.

Vehicle speed

Ambient air temperature

DTE (distance to empty)

Average fuel consumption

Average vehicle speed

Trip time

Trip distance

St op watc h

Shift-up indicator setting mode
How to Change/ Reset the Displayed Mode

The displayed mode can be selected in the following order by momentarily pressing the trip computer
mode switch.

speed → Trip time and trip distance → Stopwatch → Shift-up indicator setting

Holding the trip computer setting switch for more than 1 second resets the displayed mode (Average fuel
consumption, average vehicle speed, trip time, trip distance or stopwatch).
