Juke F15 (2012 year). Service Repair Manual — part 9

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.

The vehicle may be equipped with a passenger air bag deactivation switch. The switch is designed to turn off
the passenger air bag so that a rear-facing child restraint can be used in the front passenger seat, since no
rear seat exists where a rear-facing child restraint can be placed. The switch is located in the center of the
instrument panel, near the ashtray. When the switch is turned to the ON position, the passenger air bag is
enabled and could inflate for certain types of collision. When the switch is turned to the OFF position, the pas-
senger air bag is disabled and does not inflate. A passenger air bag OFF indicator on the instrument panel illu-
minates when the passenger air bag is switched OFF. The driver air bag always remains enabled and is not
affected by the passenger air bag deactivation switch.

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 “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.

• The vehicle may be equipped with a passenger air bag deactivation switch which can be operated by

the customer. When the passenger air bag is switched OFF, the passenger air bag is disabled and
does not inflate. When the passenger air bag is switched ON, the passenger air bag is enabled and
could inflate for certain types of collision. After SRS maintenance or repair, check that the passenger
air bag deactivation switch is in the same position (ON or OFF) as when the vehicle arrived for ser-
vice.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• 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 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-III 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-
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.

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 VOLUME DIAL POSITION

BCM judges the wiper volume dial 1 - 7 by the status of WIP VOLUME 1, 2 and 3 switches.

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 display 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.

A/C ON signal

• A/C auto amp. (Auto A/C)
• A/C control (Manual A/C)

ECM (CAN)

Input A/C ON signal (automatic

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.

Sleep condition

Wake-up operation

• BCM transmits sleep wake up signal (wake up) to each unit when any condition listed below is established,

and then goes into normal mode from low power consumption mode.

• Each unit starts transmissions with CAN communication by receiving sleep wake up signals. Each unit trans-

mit wake up signals to BCM with CAN communication to convey the start of CAN communication.
