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.

OPERATION DESCRIPTION

• BCM detects that the rear window defogger switch turns ON while ignition switch is ON, and then transmits

the rear window defogger control signal to IPDM E/R via CAN communication for approximately 15 minutes.

• IPDM E/R turns rear window defogger relay ON when it receives rear window defogger control signal.

relay turns ON.

• When rear window defogger is activated, indicator lamp on rear window defogger switch turns ON.
*: For models with door mirror defogger.

TIMER FUNCTION

• BCM transmits rear window defogger control signal to IPDM E/R for approximately 15 minutes when rear

window defogger switch is turns ON while ignition switch is ON. Then, IPDM E/R activates rear window
defogger and door mirror defogger*.

• The timer is cancelled if the rear window defogger switch is pressed again during timer operation. BCM

stops the output of rear window defogger control signal. The same action occurs during timer operation if the
ignition switch is OFF.

INFOID:0000000007808996

AUTO ACTIVE TEST

Description

In auto active test mode, the IPDM E/R sends a drive signal to the following systems to check their operation.
• Rear window defogger
• Front wiper motor
• Parking lamp
• License plate lamp
• Tail lamp
• Side marker lamp
• Front fog lamp
• Headlamp (LO, HI)
• A/C compressor (magnet clutch)
• Cooling fan

Operation Procedure

CAUTION:

Wiper arm interferes with food when wiper is operated while wiper arm is in the raised position.
Always perform auto active test without setting wiper arm in the raised position. Always pour water on
front windshield glass in advance to auto active test so that damage on front windshield glass surface
is prevented.

Turn the ignition switch OFF.

Turn the ignition switch ON, and within 20 seconds, press the driver door switch 10 times. Then turn the
ignition switch OFF.

CAUTION:

Close passenger door.

Turn the ignition switch ON within 10 seconds. After that the horn sounds once and the auto active test
starts.

CAUTION:

Engine starts when ignition switch is turned ON while brake pedal is depressed.

After a series of the following operations is repeated 3 times, auto active test is completed.

NOTE:
• When auto active test mode has to be cancelled halfway through test, turn the ignition switch OFF.
• When auto active test is not activated, door switch may be the cause. Check door switch. Refer to
