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

INFOID:0000000006247768

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

Instruction.

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 Instruction. 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 Necessary for Steering Wheel Rotation After Battery Disconnect

INFOID:0000000008191796

NOTE:

• This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

TEM).

• Remove and install all control units after disconnecting both battery cables with the ignition knob in the

″

LOCK

″

position.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-

anism is adopted on the key cylinder.

For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and

steering wheel rotation will become impossible.

If steering wheel rotation is required when battery power is interrupted, follow the procedure below before

starting the repair operation.

OPERATION PROCEDURE

1. Connect both battery cables.

NOTE:

Supply power using jumper cables if battery is discharged.

2. Use the Intelligent Key or mechanical key to turn the ignition switch to the

″

ACC

″

position. At this time, the

steering lock will be released.

3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be

rotated.

PRECAUTIONS

4. Perform the necessary repair operation.
5. When the repair work is completed, return the ignition switch to the

″

LOCK

″

position before connecting

the battery cables. (At this time, the steering lock mechanism will engage.)

6. Perform a self-diagnosis check of all control units using CONSULT-III.

Precautions for Trouble Diagnosis

INFOID:0000000006247769

CAUTION:

• Never apply 7.0 V or more to the measurement terminal.

• Use a tester with open terminal voltage of 7.0 V or less.

• Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when

checking the harness.

Precautions for Harness Repair

INFOID:0000000006247770

• Solder the repaired area and wrap tape around the soldered area.

NOTE:

A fray of twisted lines must be within 110 mm (4.33 in).

• Bypass connection is never allowed at the repaired area.

NOTE:

Bypass connection may cause CAN communication error. The

spliced wire becomes separated and the characteristics of twisted

line are lost.

• Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communica-

tion line.
