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.

TRANSIT MODE CANCEL OPERATION

Description

INFOID:0000000007805629

• BCM is in transit mode if turn signal indicator on combination meter turns ON for 1 minute when ignition

switch is turned from OFF to ON.

• In this case, cancel operation must be performed.
NOTE:
Do not cancel transit mode during storage of the vehicle. Always cancel transit mode before delivery of the
vehicle to customer.

Work Procedure

TRANSIT MODE CANCEL OPERATION

Turn ignition switch OFF.

Turn and hold front wiper switch to HI, and then operate turn signal switch to RH or LH.

>> GO TO 2.

TRANSIT MODE CANCEL CHECK

Turn front wiper switch and turn signal switch OFF.

Turn ignition switch ON.

Check that turn signal indicator on combination meter does not turn ON.

• 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.

• 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-

• BCM operates as follows and judges the status of the combination switch.
- INPUT 1 - 5 outputs the voltage waveforms of 5 systems simultaneously.
- It operates the transistor on OUTPUT side in the following order: OUTPUT 5

→

- The voltage waveform of INPUT corresponding to the formed circuit changes according to the operation of

the transistor on OUTPUT side if any (1 or more) switches are ON.

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