When installing fluid cooler tube to transaxle assembly, assem-
ble the part with the tube aligned with the rib. 

When installing transaxle to the engine, attach the fixing bolts in
accordance with the following standard.

Align the positions of tightening nuts for drive plate with those of
the torque converter, and temporarily tighten the nuts. Then,
tighten the nuts with the specified torque.

CAUTION:

Do not reuse O-ring and copper washers.

When turning crankshaft, turn it clockwise as viewed
from the front of the engine.

When tightening the tightening nuts for the torque con-
verter after fixing the crankshaft pulley bolts, be sure to
confirm the tightening torque of the crankshaft pulley mounting bolts. Refer to 

EM-68, "INSTAL-

LATION"

 .

 After converter is installed to drive plate, rotate crankshaft several turns and check to be sure
that transaxle rotates freely without binding.

Install crankshaft position sensor (POS) sensor. Refer to 

EM-29, "Removal and Installation"

 .

After completing installation, check for fluid leakage, fluid level, and the positions of CVT. Refer to 

CVT-15,

"Checking CVT Fluid"

 , 

CVT-201, "Adjustment of CVT Position"

 , 

CVT-202, "Checking of CVT Position"

 .

When replacing the CVT assembly, erase EEP ROM in TCM. Refer to 

CVT-9, "Precautions for TCM and

CVT Assembly Replacement"

 .

PRECAUTION 

PFP:00011

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

NKS001RY

The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Man-
ual.

WARNING:

To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

PFP:24814

System Description

NKS001S0

UNIFIED METER CONTROL UNIT

Speedometer, odo/trip meter, tachometer, fuel gauge and water temperature gauge are controlled by the
unified meter control unit, which is built into the combination meter. Unified meter control unit receives sig-
nals from unified meter and A/C amp.

Warning lamp and indicator lamp of combination meter are controlled by signals drawn from the unified
meter and A/C amp.

Digital meter is adopted for odo/trip meter.

Odo/trip meter and CVT indicator segments can be checked in self-diagnosis mode.

Meters/gauges can be checked in self-diagnosis mode.

POWER SUPPLY AND GROUND CIRCUIT

Power is supplied at all times

through 10A fuse [No. 19, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 21,

through 10A fuse [No. 21, located in the fuse block (J/B)]

to combination meter terminal 21.

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 combination meter terminal 20,

through 10A fuse [No. 12, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 22.

With the ignition switch in the ON position, power is supplied

through 15A fuse [No. 10, located in the fuse block (J/B)], and

through 15A fuse [No. 11, located in the fuse block (J/B)]

to unified meter and A/C amp. terminal 46.

Ground is supplied

to combination meter terminals 22, 23 and 24

through grounds M14 and M78,

to unified meter and A/C amp. terminals 29 and 30

through grounds M14 and M78.

SPEEDOMETER

The speedometer indicates the vehicle speed.

ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C
amp. with CAN communication.

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 indicates the vehicle speed according to vehicle speed signal (8-pulse) signal.

TACHOMETER

The tachometer indicates engine speed in revolutions per minute (rpm).

ECM provides engine speed signal to unified meter and A/C amp. with CAN communication.

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

The water temperature gauge indicates the engine coolant temperature.

ECM provides engine coolant temperature signal to unified meter and A/C amp. with CAN communica-
tion.

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

The fuel gauge indicates the approximate fuel level in the fuel tank.

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 the fuel level sensor unit and fuel pump (main) terminals 5 and 7

through the fuel level sensor unit (sub), and

through the fuel level sensor unit and fuel pump (main) terminals 6 and 2

to unified meter and A/C amp. terminal 28 for the fuel gauge.

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 the fuel level signal.

ODO/TRIP METER

ABS actuator and electric unit (control unit) provides a vehicle speed signal to the unified meter and A/C
amp. with CAN communication.

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 For Odo/trip Meter 

Depressing the odo/trip meter switch toggles the mode in the following order.

The odo/trip meter display mode toggling and trip display reset-
ting can be identified by the amount of time that elapses from
pressing the odo/trip meter switch (1) to releasing it.

When resetting with “trip A” displayed, only “trip A” display is
reset.

NOTE:
The record of the odo meter is kept even if the battery cable is dis-
connected. The record of the trip meter is erased when the battery
cable is disconnected.

COMBINATION METER ILLUMINATION CONTROL
Daytime Mode

When ignition switch is turned ON, combination 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 nighttime mode, illumination control switch (1) illumination
turns ON by unified meter control unit. Each illumination is con-
trolled by unified meter control unit.

Each illumination can be adjusted to 16 step by illumination con-
trol switch (1) in nighttime mode.

NOTE:
For further details of illumination circuit, refer to
