PRECAUTION

PRECAUTIONS

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

INFOID:0000000009161036

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.

Precaution for Battery Service

INFOID:0000000009161037

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000009161038

When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc to prevent damage to
windshield.

Precautions For Xenon Headlamp Service

INFOID:0000000009161039

WARNING:

Comply with the following warnings to prevent any serious accident.

PIIB3706J

Revision: 2012 November

2014 GT-R

EC-20

< PRECAUTION >

[VR38]

PRECAUTIONS

• Disconnect the battery cable (negative terminal) or the power supply fuse before installing, remov-

ing, or touching the xenon headlamp (bulb included). The xenon headlamp contains high-voltage
generated parts.

• Never work with wet hands.
• Check the xenon headlamp ON-OFF status after assembling it to the vehicle. Never turn the xenon

headlamp ON in other conditions. Connect the power supply to the vehicle-side connector.
(Turning it ON outside the lamp case may cause fire or visual impairments.)

• Never touch the bulb glass immediately after turning it OFF. It is extremely hot.

CAUTION:

Comply with the following cautions to prevent any error and malfunction.
• Install the xenon bulb securely. (Insufficient bulb socket installation may melt the bulb, the connec-

tor, the housing, etc. by high-voltage leakage or corona discharge.)

• Never perform HID circuit inspection with a tester.
• Never touch the xenon bulb glass with hands. Never put oil and grease on it.
• Dispose of the used xenon bulb after packing it in thick vinyl without breaking it.
• Never wipe out dirt and contamination with organic solvent (thinner, gasoline, etc.).

On Board Diagnostic (OBD) System of Engine and Transmission

INFOID:0000000009161040

The ECM has 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 disconnect the negative battery cable before any repair

or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will
cause the MIL to illuminate.

• Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will

cause the MIL to illuminate due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)

• Certain systems and components, especially those related to OBD, may use a new style slide-lock-

ing type harness connector. For description and how to disconnect, refer to

GI-34, "Control Units

and Electrical Parts"

• Be sure to route and secure the harnesses properly after work. The interference of the harness with

a bracket, etc. may cause the MIL to illuminate due to the short circuit.

• Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube

may cause the MIL to illuminate due to the malfunction of the EVAP system or fuel injection system,
etc.

• Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM and

TCM (Transmission control module) before returning the vehicle to the customer.

General Precautions

INFOID:0000000009161041

• After finishing servicing, check that all the tools and waste are stored in a customary place.
• Always use a 12 volt battery as power source.
• Never attempt to disconnect battery cables while engine is

running.

• Before connecting or disconnecting the ECM harness con-

nector, turn ignition switch OFF and disconnect negative bat-
tery cable. Failure to do so may damage the ECM because
battery voltage is applied to ECM even if ignition switch is
turned OFF.

• Before removing parts, turn ignition switch OFF and then dis-

connect battery ground cable.

SEF289H

Revision: 2012 November

2014 GT-R

PRECAUTIONS

EC-21

< PRECAUTION >

[VR38]

• Never disassemble ECM.
• If a battery cable is disconnected, the memory will return to

the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slightly when the terminal is dis-
connected. However, this is not an indication of a malfunc-
tion. Never replace parts because of a slight variation.

• If the battery is disconnected, the following emission-related

diagnostic information will be lost within 24 hours.

- Diagnostic trouble codes
- 1st trip diagnostic trouble codes
- Freeze frame data
- 1st trip freeze frame data
- System readiness test (SRT) codes
- Test values
• When connecting ECM harness connector (A), fasten (B) it

securely with a lever as far as it will go as shown in the figure.

• When connecting or disconnecting pin connectors into or

from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.

• Securely connect ECM harness connectors.

A poor connection can cause an extremely high (surge) volt-
age to develop in coil and condenser, thus resulting in dam-
age to ICs.

• Keep engine control system harness at least 0.1 m (0.3 ft)

away from adjacent harness, to prevent engine control sys-
tem malfunctions due to receiving external noise, degraded
operation of ICs, etc.

• Keep engine control system parts and harness dry.
• Before replacing ECM, perform ECM Terminals and Reference

Value inspection and make sure ECM functions properly.

• Handle mass air flow sensor carefully to avoid damage.
• Never clean mass air flow sensor with any type of detergent.
• Never disassemble electric throttle control actuator.
• Even a slight leak in the air intake system can cause serious

incidents.

• Never shock or jar the camshaft position sensor (PHASE),

crankshaft position sensor (POS).

Special Cautions to Ensure the Safe Disposal of Sodium-filled Exhaust Valves

INFOID:0000000009162806

Handling and disposal of sodium-filled exhaust valves requires spe-
cial care and consideration. Under conditions such as breakage with
subsequent contact with water, metal sodium which lines the inner
portion of exhaust valve will react violently, forming sodium hydrox-
ide and hydrogen which may result in an explosion. Sodium-filled
exhaust valve is identified on the top of its stem as shown in illustra-
tion.

DEALER DISPOSAL INSTRUCTIONS

CAUTION:

• Use approved shatter-resistant eye protection when performing this procedure.
• Perform this and all subsequent disposal work procedures in an open room, away from flammable

liquids. Keep a fire extinguisher, rated at least 10 ABC, in close proximity to the work area.

• Be sure to wear rubber gloves when performing the following operations.
• Make sure the resultant (high alkalinity) waste water does not contact your skin. If the waste water

does contact you, wash the contacted area immediately with large quantities of water.

• Dealers should check their respective state and local regulations concerning any chemical treatment

or waste water discharge permits which may be required to dispose of the resultant (high alkalinity)
waste water.

< PRECAUTION >

PRECAUTIONS

Clamp valve stem in a vice.

The valve has a specially-hardened surface. To cut through it,
first remove a half-round section, approximately 30 mm (1.18 in)
long using air-powered grinder until black color is removed and
silver color appears.

Use hacksaw to cut through approximately half the diameter of
valve stem. Make the serration at a point 40 mm (1.57 in) from
the end of valve stem.

Cover the serrated end of the valve with a large shop towel (A).
Strike the valve face end with a hammer, separating it into two
pieces.

Fill a bucket (such as a 20 oil can) with at least 10 (2-1/4
lmp gal) of water. Carefully place the alreadycut (serrated)
valves into the water one-at-a-time using a set of large tweezers
and quickly move away at least 2.7 m (9 ft).

The valves should be placed in a standing position as shown in
the illustration to allow complete reaction. After the bubbling
action has subsided, additional valves can be placed into the
bucket allowing each subsequent chemical reaction to subside.
However, no more than 8 valves should be placed in the same
10 (2-1/4 lmp gal) amount of water. The complete chemical
reaction may take as long as 4 to 5 hours. Remove the valves
using a set of large tweezers after the chemical reaction has
stopped. Afterwards, valves can be disposed as ordinary scrap.
