TRANSIT MODE
• Transit mode inhibits battery power consumption during transportation or storage of the vehicle.
• BCM is set to transit mode before delivery.
• In transit mode, remote keyless entry function, headlamp ON/OFF function, theft warning alarm function,
and other BCM control functions do not operate normally.
• Therefore, cancel operation must be performed so that the vehicle is used in normal status.
• For transit mode cancel operation, refer to
NOTE:
Do not cancel transit mode during storage of the vehicle. Always cancel transit mode before delivery of the
vehicle to customer.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000007576690
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.

• BCM (Body Control Module) controls various electrical components.It receives the information required from
CAN communication and the signals received from each switch and sensor.
• BCM has a combination switch reading function for reading the status of combination switches (light, turn
signal, wiper and washer) in addition to functions for controlling the operation of various electrical compo-
nents. It also has a signal transmission function, for other systems, and a power consumption control func-
tion that reduces the power consumption with the ignition switch OFF.
• BCM is equipped with a diagnosis function that operates with CONSULT and allows for various settings to
be changed.

BODY CONTROL SYSTEM : Fail-safe
INFOID:0000000007576694
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 auto stop signal.
When the rear wiper auto stop signal does not change more than 5 seconds while driving the rear wiper, BCM
stops power supply to protect the rear wiper motor.
Condition of cancellation
1.
Pass more than 1 minute after the rear wiper stop.
2.
Turn rear wiper switch OFF.
3.
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.
NOTE:
When voltage of battery power supply is approximately 9 V or more, combination switch reading function
returns to normal operation.

• 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
→
2
→
3
→
4
→
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.
Operation Example
In the following operation example, the combination of the status signals of the combination switch is replaced
as follows: INPUT 1 - 5 to “1 - 5” and OUTPUT 1 - 5 to “A - E”.
Example 1: When a switch (TAIL LAMP switch) is turned ON

• The circuit between OUTPUT 4 and INPUT 5 is formed when the TAIL LAMP switch is turned ON.
• BCM detects the combination switch status signal “5D” when the signal of OUTPUT 4 is input to INPUT 5.
• BCM judges that the TAIL LAMP switch is ON when the signal “5D” is detected.
Example 2: When some switches (TURN RH switch, TAIL LAMP switch) are turned ON
• The circuits between OUTPUT 1 and INPUT 5 and between OUTPUT 4 and INPUT 5 are formed when the
TURN RH switch and TAIL LAMP switch are turned ON.
• BCM detects the combination switch status signal “5AD” when the signals of OUTPUT 1 and OUTPUT 4 are
input to INPUT 5.
• BCM judges that the TURN RH switch and TAIL LAMP switch are ON when the signal “5AD” is detected.
WIPER INTERMITTENT DIAL POSITION
BCM judges the wiper intermittent dial 1 - 7 by the status of INT VOLUME 1, 2 and 3 switches.

POWER CONSUMPTION CONTROL SYSTEM : System Description
INFOID:0000000007576700
OUTLINE
• BCM incorporates a power saving control function that reduces the power consumption according to the
vehicle status.
• BCM switches the status (control mode) by itself with the power saving control function. It performs the sleep
request to each unit (IPDM E/R, combination meter and multi control unit) that operates with the ignition
switch OFF.
Normal mode (wake-up)
- CAN communication is normally performed with other units
- Each control with BCM is operating properly
CAN communication sleep mode (CAN sleep)
- CAN transmission is stopped
- Control with BCM only is operating
Low power consumption mode (BCM sleep)
- Low power consumption control is active
- CAN transmission is stopped
LOW POWER CONSUMPTION CONTROL WITH BCM
BCM reduces the power consumption with the following operation in the low power consumption mode.
• The reading interval of the each switches changes from 10 ms interval to 60 ms interval.
Sleep mode activation
• BCM receives the sleep-ready signal (ready) from IPDM E/R and combination meter via CAN communica-
tion.
• BCM transmits the sleep wake up signal (sleep) to each unit when all of the CAN sleep conditions are ful-
filled.
• Each unit stops the transmission of CAN communication with the sleep wake up signal. BCM is in CAN com-
munication sleep mode.
• BCM is in the low power consumption mode and perform the low power consumption control when all of the
BCM sleep conditions are fulfilled with CAN sleep condition.
