Revision: 2006 November2007 350Z
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 , "
ILLUMINA-
TION" .

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.

TRIP COMPUTER
Function
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.
–Vehicle speed → Ambient air temperature → DTE → Average fuel consumption and average vehicle
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).
NOTE:
When the ambient air temperature warning, the tire pressure warning, and the DTE warning, match warning
conditions at the same time, the display automatically displays the ambient air temperature warning.
Vehicle Speed

Trip computer receives vehicle speed signal from combination meter through the unified meter and A/C
amp. with communication line.

Trip computer displays the vehicle speed according to vehicle speed signal.
Ambient Air Temperature

Unified meter and A/C amp. reads ambient air temperature signal from ambient air temperature sensor.
Signal is supplied
–from unified meter and A/C amp. terminal 39
–through ambient sensor terminal 1 and 2
–to unified meter and A/C amp. terminal 49.

Trip computer receives ambient air temperature signal from the unified meter and A/C amp. with commu-
nication line.

Trip computer displays ambient air temperature according to ambient air temperature signal.
NOTE:

Indication range is between −30 and 55 °C (−22 and 131 °F).

When ambient air temperature is less than −30 °C (−22 °F) or more than 55 °C (131 °F), the display
shows “--”.

When ambient air temperature is less than 3 °C (37 °F) continuously, the display shows “ICY” as warning.
At more than 4 °C (39 °F) the display stops showing “ICY”.

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:

reconnected. In this case, with the sensor connected, disconnect
and reconnect the battery, then the correct temperature will be dis-
played.Refer to ATC-92, "
