CAUTION:
After disconnecting the CONSULT vehicle interface (VI) from the data link connector, the ignition must
be cycled OFF → ON (for at least 5 seconds) → OFF. If this step is not performed, the BCM may not go
to ”sleep mode”, potentially causing a di scharged battery and a no-start condition.

RELIEF OIL PRESSURE
CAUTION:
Make sure that belt tension is normal be fore starting the following procedure.
1. Connect the Tool between oil pump discharge connector and high-pressure hose. Bleed air from the hydraulic circuit while
opening valve fully. Refer to ST-30, "Air Bleeding Hydraulic Sys-
tem".
2. Start engine. Run engine until power steering fluid temperature reaches 50 ° - 80 °C (122 ° - 176 °F).
CAUTION:
• Leave the valve of the hydraulic pressure gauge fully open while starting and ru nning engine. If engine is
started with the valve closed, th e hydraulic pressure in oil
pump goes up to the relief pressure along with unusual
increase of fluid temperature.
• Be sure to keep hose clear of belts and other parts when engine is started.
3. Fully close the Tool valve with engine at idle and measure the relief oil pressure.
CAUTION:
Do not keep valve closed for 10 seconds or longer.
4. Open the valve slowly after measuring. Replace oil pump if the relief oil pressure is outside the standard.
5. After inspection, disconnect the Tool from hydraul ic circuit, then add fluid and bleed air. Refer to ST-30,
"Air Bleeding Hydraulic System".

PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951730
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.
Service Notice and Precautions for Hydrau lic Pump Electric Power Steering System
INFOID:0000000009460340
• Check each tire for proper air pressure and size. Refer to WT-60, "Tire".
• Verify that the steering system components are G enuine NISSAN parts and have been installed properly.
• Check the steering column for loose mounting bolts.
• Check the steering gear assembly for loose mounting bolts. Check the inner sockets and outer sockets for
damage or wear. Inspect the boots and seals for leakage of power steering fluid.
• Verify proper wheel alignment. Refer to FSU-7, "Inspection and Adjustment"
.
• Check for any damage, wear, or modification to the suspension and body that would result in increased
weight or an improper wheelarch height. Refer to FSU-26, "Wheelarch Height (Unladen*
1)".
• Check for proper battery voltage.
• Verify that all power steering pump assembly connections are clean and fully seated.
• Verify that only Genuine NISSAN E-PSF is used. Use of any power steering fluid other than Genuine NIS-
SAN E-PSF will prevent the power st eering system from proper operation.
• An audible high pitch noise may be heard from the engine compartment when the steering wheel is oper-
ated, particularly at low speeds such as a parking lot maneuver. This condition is not a malfunction, rather
normal system operation. Steering at low speeds or parking lot maneuvers demands higher hydraulic assis-
tance, resulting in larger power st eering pump load and increased system noise.
• The power steering pump is electrically controlled by the power steering control module.
• Before connecting or disconnecting the power steeri ng control module harness connectors, turn ignition
switch “OFF” and disconnect battery ground cable. Batter y voltage is applied to power steering control mod-
ule even if ignition switch is turned “OFF”.

COMPONENT PARTS
*: These components are included in control valve assembly.
CVT CONTROL SYSTEM : TCMINFOID:0000000009463963
• The vehicle driving status is judged based on the signals
from the sensors, switches, and other control units,
and the optimal transaxle control is performed.
• For TCM control items, refer to TM-30, "CVT CONTROL SYSTEM : System Description"
.
CVT CONTROL SYSTEM : Transmission Range SwitchINFOID:0000000009463964
• The transmission range switch is installed to upper part of transaxle case.
• The transmission range switch detects the selector lever position.
CVT CONTROL SYSTEM : Primary Speed SensorINFOID:0000000009463965
• The primary speed sensor is installed to side cover of transaxle.
• The primary speed sensor detects primary pulley speed.
• The primary speed sensor generates an ON-OFF pulse signal according to the rotating body speed. TCM

COMPONENT PARTS
• 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.
CVT CONTROL SYSTEM : Primary Pressure SensorINFOID:0000000009463969
• The primary pressure sensor is installed to control valve.
• The primary pressure sensor detects the pressure applied to the primary pulley.
• 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:0000000009463970
• The secondary pressure sensor is installed to control valve.
• The secondary pressure sensor detects the pressure applied to the secondary pulley.
