PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951697
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service t he system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 performed by
an authorized NISSAN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipm ent on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Un it or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or el ectric power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three mi nutes before performing any service.
Precaution for Procedure without Cowl Top CoverINFOID:0000000009464173
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.
Precaution for TCM and Tran saxle Assembly ReplacementINFOID:0000000009464174
CAUTION:
• To replace TCM, refer to TM-282, "Description"
.
• To replace transaxle assembly, refer to TM-283, "Description"

On Board Diagnosis (OBD) System of CVT and EngineINFOID:0000000009464176
The TCM and ECM have an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to
warn the driver of a malfunction causing emission deterioration.
CAUTION:
• Be sure to turn the ignition switch OFF and di sconnect the battery cable from the negative terminal
before any repair or inspection work. The open/s hort circuit of related switches, sensors, solenoid
valves, etc. will cause the MIL to light up.
• Be sure to connect and lock the connectors secure ly after work. A loose (unlocked) connector will
cause the MIL to light up due to an open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
• Be sure to route and secure the harnesses properly after work. Interference of the harness with a
bracket, etc. may cause the MIL to light up due to a short circuit.
• Be sure to connect rubber tubes properly afte r work. A misconnected or disconnected rubber tube
may cause the MIL to light up due to a malfunction of the EGR system or fuel injection system, etc.
• Be sure to erase the unnecessary malfunction informa tion (repairs completed) from the TCM and
ECM before returning the vehicle to the customer.
Removal and Installation Proc edure for CVT Unit ConnectorINFOID:0000000009464177
REMOVAL
• Rotate bayonet ring counterclockwise. Pull out CVT unit har-
ness connector upward and remove it.
INSTALLATION
1. Align marking on CVT unit harness connector terminal with marking on bayonet ring. Insert CVT unit harness connector.

COMPONENT PARTS
• The primary speed sensor generates an ON-OFF pulse
signal according to the rotating body speed. TCM
judges the rotating body speed from the pulse signal.
CVT CONTROL SYSTEM : Output Speed SensorINFOID:0000000009464184
• The output speed sensor is installed to back side of transaxle.
• The output speed sensor detects final gear speed.
• The output speed sensor generates the ON-OFF pulse (short waveform) in proportion to the rotating body
speed which is “The higher the rotating body speed is, t he faster the change cycle is”. The TCM judges the
rotating speed from the changing cycle of this pulse signal.
CVT CONTROL SYSTEM : Input Speed SensorINFOID:0000000009464185
• The input speed sensor is installed to the front side of transaxle case.
• The input speed sensor detects input shaft speed.

• The CVT fluid temperature sensor detects CVT fluid temperature in oil pan.
• The fluid temperature sensor uses a thermistor, and changes the signal voltage by converting changes in the
CVT fluid temperature to a resistance value. TCM eval uates the CVT fluid temperature from the signal volt-
age value.

COMPONENT PARTS
• When pressure is applied to the ceramic device in
the primary pressure sensor, the ceramic device is
deformed, resulting in voltage change. TCM evaluates the primary pressure from its voltage change. Voltage
is increased along with pressure increase.
CVT CONTROL SYSTEM : Secondary Pressure SensorINFOID:0000000009464188
• The secondary pressure sensor is installed to control valve.
• The secondary pressure sensor detects the pressure applied to the secondary pulley.
• When pressure is applied to the metal diaphragm in the secondary pressure sensor, the metal diaphragm is
deformed, resulting in voltage change. TCM evaluates the secondary pressure from its voltage change. Volt-
age is increased along with pressure increase.
CVT CONTROL SYSTEM : Primary Pressure Solenoid ValveINFOID:0000000009464189
• The primary pressure solenoid valve is installed to control valve.
• The primary pressure solenoid valve controls the prim ary reducing valve. For information about the primary
reducing valve, refer to TM-229, "TRANSAXLE : Component Description"
.
• The primary pressure solenoid valve uses the linear solenoid valve [N/H (normal high) type].
NOTE:
• The principle of the linear solenoid valve utilizes the fa ct that the force pressing on the valve spool installed
inside the coil increases nearly in proportion to the current . This allows it to produce a fluid pressure that is
proportional to this pressing force.
• The N/H (normal high) produces hydraulic control when the coil is not energized.
CVT CONTROL SYSTEM : Secondary Pressure Solenoid ValveINFOID:0000000009464190
• The secondary pressure solenoid valve is installed to control valve.
• The secondary pressure solenoid valve controls t he secondary reducing valve. For information about the
secondary reducing valve, refer to TM-229, "TRANSAXLE : Component Description"

• CVT detects the vehicle driving status from switc hes, sensors and signals, and controls the vehicle so that
the optimum shift position and shift timing may always be achieved. It also controls the vehicle to reduce
shift and lockup shock, etc.
• Receives input signals from switches and sensors.
• Sends the output signal necessary for operation of so lenoid valves, and evaluates the line pressure, shift
timing, lockup operation, engine brake performance, etc.
• If a malfunction occurs on the electric system, activa te the fail-safe mode only to drive the vehicle.
LIST OF CONTROL ITEMS AND INPUT/OUTPUT
*: If these input/output signals show errors, TCM activates the fail-safe function.
CVT CONTROL SYSTEM : Fail-safeINFOID:0000000009464205
TCM has a fail-safe mode. The mode functions so that operation can be continued even if the signal circuit of
the main electronically controlled input/output parts is damaged.
If the vehicle shows following behaviors including “poor acceleration”, a malfunction of the applicable system
is detected by TCM and the vehicle may be in a fail-s afe mode. At this time, check the DTC code and perform
inspection and repair according to the malfunction diagnosis procedures.
