PRECAUTIONS

PFP:00001

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT 
BELT PRE-TENSIONER”

NKS001VF

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 and SB section of this Service Man-
ual.

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 per-
formed by an authorized NISSAN/INFINITI dealer.

Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.

BCM (BODY CONTROL MODULE)

PFP:284B2

System Description

NKS001VG

BCM (Body Control Module) controls the operation of various electrical units installed on the vehicle.

BCM FUNCTION

BCM has combination switch reading function for reading the operation of combination switches (light, wiper
washer, turn signal) in addition to a function for controlling the operation of various electrical components. Also
it has an interface function allowing it to receive signals from the unified meter and A/C amp., and send signals
to ECM using CAN communication.

COMBINATION SWITCH READING FUNCTION
Description

BCM reads combination switch (lighting switch, wiper switch) status, and controls various electrical com-
ponent according to the results.

BCM reads information of a maximum of 20 switches by combining 5 output terminals (OUTPUT 1-5) and
5 input terminals (INPUT 1-5).

Operation Description

BCM activates transistors of output terminals (OUTPUT 1-5) periodically, and allows current to flow in
turn.

If any (1 or more) switches are turned ON, circuit of output terminals (OUTPUT 1-5) and input terminals
(INPUT 1-5) becomes active.

At this time, transistors of output terminals (OUTPUT 1-5) are activated to allow current to flow. When volt-
age of input terminals (INPUT 1-5) corresponding to that switch changes, interface in BCM detects volt-
age change, and BCM determines that switch is ON.

BCM (BODY CONTROL MODULE)

Revision: 2006 July

Operation Table of BCM and Combination Switches

BCM reads operation status of combination switch using combinations shown in table below.

NOTE:
Headlamp has a dual system switch.

Sample Operation: (When Lighting Switch 1ST Position Turned ON)

When lighting switch 1ST position is turned ON, contact in combination switch turns ON. At this time if
OUTPUT 4 transistor is activated, BCM detects that voltage changes in INPUT 5.

When OUTPUT 4 transistor is ON, BCM detects that voltage changes in INPUT 5, and judges that lighting
switch 1ST position is ON. Then BCM sends tail lamp ON signal to IPDM E/R using CAN communication.

When OUTPUT 4 transistor is activated again, BCM detects that voltage changes in INPUT 5, and recog-
nizes that lighting switch 1ST position is continuously ON.

NOTE:
Each OUTPUT terminal transistor is activated at 10 ms intervals. Therefore after switch is turned ON,
electrical loads are activated with time delay. But this time delay is so short that it cannot be detected by
human senses.

Operation Mode

Combination switch reading function has operation modes shown below.

1.

Normal status
When BCM is not in sleep status, OUTPUT terminals (1-5) send out ON signal every 10 ms.

2.

Sleep status
When BCM is in sleep status, transistors of OUTPUT 1 and 5 stop the output, and BCM enters low power
mode. Mean while OUTPUT 2, 3, and 4 send out ON signal every 60 ms, and accept input from lighting
switch system.

CAN COMMUNICATION CONTROL

CAN communication allows a high rate of information transmission through the two communication lines (CAN
L line, CAN H line) connecting the various control units in the system. Each control unit transmits/receives
data but selectively reads required data only. For details of signals that are transmitted/received by BCM via
CAN communication, refer to 

LAN-49, "CAN System Specification Chart"

 .

BCM (BODY CONTROL MODULE)

Revision: 2006 July

BCM STATUS CONTROL

BCM changes its status depending on the operation status in order to save power consumption.

1.

CAN communication status

With ignition switch ON, CAN communicates with other control units normally.

Control by BCM is being operated properly.

When ignition switch is OFF, switching to sleep mode is possible.

Even when ignition switch is OFF, if CAN communication with IPDM E/R and combination meter is
active, CAN communication status is active.

2.

Sleep transient status

This status shuts down CAN communication when ignition switch is turned OFF.

It transmits sleep request signal to IPDM E/R and combination meter.

2 seconds after CAN communication of all control units stops, sleep transient status is switched to CAN
communication inactive status.

3.

CAN communication inactive status

With ignition switch OFF, CAN communication is not active.

With ignition switch OFF, control performed only by BCM is active.

3 seconds after CAN communication of all control units stops, CAN communication inactive status is
switched to sleep status.

4.

Sleep status

BCM is activated with low power mode.

CAN communication is not active.

When CAN communication operation is detected, it switches to CAN communication status.

When a state of the following switches changes, it switches to CAN communication state.

Key switch

Hazard switch

Door lock/unlock switch

Front door switch (driver side, passenger side)

Rear door switch (LH, RH)

Back door opener switch

Combination switch (passing, lighting switch 1ST position, front fog lamp)

Key fob (lock/unlock signal)

Key cylinder switch

When control performed only by BCM is required by switch, it shifts to CAN communication inactive
mode.

Operation mode of combination switch reading function is changed.
