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.

OUTLINE

• BCM (Body Control Module) controls the various electrical components. It inputs the information required to

the control from CAN communication and the signal received from each switch and sensor.

• BCM has combination switch reading function for reading the operation status of combination switches (light,

turn signal, wiper and washer) in addition to a function for controlling the operation of various electrical com-
ponents. It also has the signal transmission function as the passed point of signal and the power saving con-
trol function that reduces the power consumption with the ignition switch OFF.

• BCM is equipped with the diagnosis function that performs the diagnosis with CONSULT and various set-

tings.

BODY CONTROL SYSTEM : Fail-safe

INFOID:0000000007835261

FAIL-SAFE CONTROL BY DTC

BCM performs fail-safe control when any DTC are detected.

REAR WIPER MOTOR PROTECTION

BCM detects the rear wiper stopping position according to the rear wiper stop position signal.
When the rear wiper stop position signal does not change for more than 5 seconds while driving the rear
wiper, BCM stops power supply to protect the rear wiper motor.

Condition of cancellation

More than 1 minute is passed after the rear wiper stop.

Turn rear wiper switch OFF.

Operate the rear wiper switch or rear washer switch.

FAIL-SAFE CONTROL OF COMBINATION SWITCH READING FUNCTION CAUSED BY LOW
POWER SUPPLY VOLTAGE

If voltage of battery power supply lower, BCM maintains combination switch reading to the status when input
voltage is less than approximately 9 V.

COMBINATION SWITCH READING FUNCTION

Description

• BCM reads the status of the combination switch at 10 ms interval normally.

NOTE:
BCM reads the status of the combination switch at 60 ms interval when BCM is controlled at low power con-
sumption control mode.

• BCM operates as follows and judges the status of the combination switch.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 1

→

5, and outputs

voltage waveform.

- The voltage waveform of OUTPUT corresponding to the formed circuit is input into the interface on INPUT

side if any (1 or more) switches are ON.

- It reads this change of the voltage as the status signal of the combination switch.
