PRECAUTION

PRECAUTIONS

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

INFOID:0000000009760534

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 SR 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 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 the SR 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 har-

ness connectors.

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

WARNING:

• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion ON or engine running, DO NOT 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 three minutes before performing any service.

Precaution for Procedure without Cowl Top Cover

INFOID:0000000009020566

When performing the procedure after removing cowl top cover, cover

the lower end of windshield with urethane, etc to prevent damage to

windshield.

On Board Diagnostic (OBD) System of Engine and CVT

INFOID:0000000009020567

The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) 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 MI to light up.

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

cause the MI to light up 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

PG-53, "Description"

PIIB3706J

PRECAUTIONS

EC-9

< PRECAUTION >

[HR16DE]

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

a bracket, etc. may cause the MI to light up due to the short circuit.

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

may cause the MI to light up due to the malfunction of the 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:0000000009020568

• Always use a 12 volt battery as power source.

• Do not 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.

• Do not 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. So,

engine operation can vary slightly in this case. However, this

is not an indication of a malfunction. Do not 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 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 10 cm (4 in) away

from adjacent harness, to prevent engine control system mal-

functions due to receiving external noise, degraded operation

of ICs, etc.

• Keep engine control system parts and harness dry.
