PRECAUTIONS

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

INFOID:0000000009745227

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. Information necessary to service the system safely is included in the SR and SB section of

this Service Instruction.

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

Instruction. 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.

Handling for Adhesive and Primer

INFOID:0000000009725689

• Do not use an adhesive which is past its usable date. Shelf life of this product is limited to six months after

the date of manufacture. Carefully adhere to the expiration or manufacture date printed on the box.

• Keep primers and adhesive in a cool, dry place. Ideally, they should be stored in a refrigerator.

• Open the seal of the primer and adhesive just before application. Discard the remainder.

• Before application, be sure to shake the primer container to stir the contents. If any floating material is found,

do not use it.

• If any primer or adhesive contacts the skin, wipe it off with gasoline or equivalent and wash the skin with

soap.

• When using primer and adhesive, always observe the precautions in the instruction instruction.

Component

Description

AV control unit

2

• AV control unit transmits A/C switch operation signal to the BCM via CAN communication line.

BCM

• Operates the rear window defogger relay with the operation of rear window defogger switch.
• Performs the timer control of rear window defogger.

A/C auto amp

1

• Transmits rear window defogger switch ON signal to the BCM.
• Turns the indicator lamp ON when detecting the operation of rear window defogger.

Rear window defogger relay

• Operates the rear window defogger and the door mirror defogger with the control signal from 

BCM.

A/C switch assembly

1

 (rear 

window defogger switch)

• Transmits rear window defogger switch ON signal.
• Turns the indicator lamp ON when detecting the operation of rear window defogger.

A/C and AV switch assembly

2

 

(rear window defogger switch)

• Transmits rear window defogger switch ON signal.
• Turns the indicator lamp ON when detecting the operation of rear window defogger.

Rear window defogger

• Heats the heating wire with the power supply from the rear window defogger relay to prevent 

the rear window from fogging up.

Door mirror defogger

3

• Heats the heating wire with the power supply from the rear window defogger relay to prevent 

the door mirror from fogging up.

System Description

INFOID:0000000009175549

Operation Description

• When rear window defogger switch is turned ON while ignition switch is ON, the rear window defogger

switch signal is transmitted to the BCM.

• BCM turns rear window defogger relay ON when rear window defogger switch signal is received.

• Rear window defogger and door mirror defogger are supplied with power and operate when rear window

defogger relay turns ON.

• Rear window defogger ON is displayed when signal is received.

• For vehicles with base audio system, A/C auto amp. transmits rear window defogger control signal to A/C

switch assembly when rear window defogger operates.

• For vehicles without base audio system, BCM transmits rear window defogger control signal to AV control

unit and A/C and AV switch assembly via CAN communication when rear window defogger operates.

Timer function

• BCM turns rear window defogger relay ON for approximately 15 minutes when rear window defogger switch

is turned ON while ignition switch is ON. It makes rear window defogger and door mirror defogger (with door

mirror defogger) operate.

• Timer is canceled after pressing rear window defogger switch again during timer operation. Then BCM turns

rear window defogger relay OFF. The same reaction also occurs during timer operation, if the ignition switch

is turned OFF.
