WARNING:

• Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait 3 minutes

or more.

• Before disconnecting the air bag sensor unit harness connector, be sure to disconnect the each har-

ness connector of the air bag module and pre-tensioner seat belt to prevent air bag deployment by
static electricity and pre-tensioner seat belt operation.

• Never use the air tools or electric tools for servicing.
• When replacing the air bag diagnosis sensor unit, always check with the parts department for the lat-

est parts information. Installing an incorrect air bag diagnosis sensor unit may or may not cause the
air bag warning lamp to illuminate and may cause incorrect deployment of the supplemental air bags
and seat belt pre-tensioners in a collision resulting in serious personal injury or death.

REMOVAL

Always check the air bag diagnosis sensor unit ECU discriminated number (identification number) using
CONSULT-III.

Disconnect the each connector of all air bag modules and pre-tensioner seat belts.

Remove the instrument lower cover (LH and RH). Refer to

IP-20, "Exploded View"

Remove the rear foot duct 1 (LH and RH). Refer to

VTL-123, "REAR FOOT DUCT 1 : Exploded View"

Remove the instrument stay LH. Refer to

IP-20, "Exploded View"

Remove the front console bracket. Refer to

IP-20, "Exploded View"

Disconnect the diagnosis sensor unit harness connectors.

CAUTION:

• Never use the old fixing bolts after removal, replace with the new fixing bolts.
• If malfunction is detected by the air bag warning lamp, after repair or replacement of the malfunc-

tioning parts, reset the memory using self-diagnosis or CONSULT-III. Refer to

SRC-17, "Diagnosis

Description"

• After the work is completed, check that no system malfunction is detected by air bag warning lamp.
• After replacing the air bag diagnosis sensor unit, confirm using CONSULT-III that the ECU discrimi-

nated number (identification number) of the new replacement air bag sensor unit matches the ECU
discriminated number (identification number) of the replaced (old) air bag diagnosis sensor unit.

NOTE:
If the ECU discriminated number of the new replacement air bag diagnosis sensor unit differs from the ECU
discriminated number of the replaced air bag diagnosis sensor unit, reconfirm the parts information and verify
that the correct air bag diagnosis sensor unit was installed.

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

INFOID:0000000006842801

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI dealer.

• Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal

injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric 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 3 minutes before performing any service.

Service Notice or Precautions for Steering System

INFOID:0000000006257697

• In case of removing steering gear assembly, make the final tightening with grounded and unloaded vehicle

condition, and then check wheel alignment.

• Observe the following precautions when disassembling.
- Before disassembly, thoroughly clean the outside of the unit.
- Disassembly should be done in a clean work area. It is important to prevent the internal parts from becoming

contaminated by dirt or other foreign matter.

- For easier and proper assembly, place disassembled parts in order on a parts rack.
- Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere with

their operation.

- Never reuse non-reusable parts.
- Before assembling, apply the specified grease to the directed parts.

Heated Steering Wheel

INFOID:0000000006842408

The heated steering wheel is activated by the power supply from the heated steering wheel relay.
Furthermore, the heated steering wheel incorporates a heating element and a thermostat to control heated
steering wheel temperatures.
• Heating element: Heat is generated by the passage of an electric current.
• Thermostat: ON/OFF operation of power supply at a certain temperature.

Heated Steering Wheel Switch

INFOID:0000000006842409

• Controls the heated steering wheel relay and operates the heated steering wheel system.

The heated steering wheel switch incorporates a timer and turns OFF the heated steering wheel relay when
operating time reaches a certain time.

- Timer: ON/OFF operation of the heated steering wheel relay at a certain time.
• Turns the indicator lamp ON when the system is activated.

Heated Steering Wheel Relay

INFOID:0000000006842410

System Description (Heated Steering Wheel)

INFOID:0000000006842411

The heated steering wheel switch controls the heated steering wheel relay. When the heated steering wheel
switch is turned on, the heated steering wheel relay is energized and the heated steering wheel system will
operate. The heated steering wheel system will turn off when the heated steering wheel temperature reaches
approximately 30

C (86

F). Heated steering wheel system operation can also be canceled by pressing the

heated steering wheel switch again. In addition, the heated steering wheel switch incorporates a timer and
turns OFF the heated steering wheel relay to exit the heated steering wheel system when the operating time
reaches a certain time.
NOTE:
If the surface temperature of the steering wheel is below 20

C (68

F), the system will heat the steering wheel

and cycle off and on to maintain a temperature above 20

C (68

F). The indicator lamp will remain on as long

as the system is on. Push the switch again to turn the heated steering wheel system off manually. The indica-
tor lamp will go off.
