PRECAUTIONS
[LAN] PFP:00001
A
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS006SI
The Supplemental Restraint System such as "AIR BAG" and "SEAT BELT PRE-TENSIONER", used along B
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 C
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: D
q 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. E
q 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. F
q 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.

IVMS (LAN)
[LAN]
IVMS (LAN) PFP:28491
Overall Description EKS001PD
OUTLINE
The In-Vehicle Multiplexing System, IVMS (LAN system), consists of a BCM (Body Control Module) and four
LCUs (Local Control Units). Some switches and electrical loads are connected to each LCU. Some electrical
systems are directly connected to the BCM. Control of each LCU (which is provided by a switch and electrical
load), is accomplished by the BCM, via multiplex data lines (A-1, A-2 or A-3) connected between them.
BCM (BODY CONTROL MODULE)
The BCM, which is a master unit of the IVMS (LAN), consists of microprocessor, memory and communication
LSI sections and has communication and control functions. It receives data signals from the LCUs and sends
electrical load data signals to them.
LCU (LOCAL CONTROL UNIT)
The LCUs, which are slave units of the BCM, have only a communication function and consist of communica-
tion LSI and input-output interface circuits. They receive data signals from the BCM, control the ON/OFF oper-
ations of electrical loads and the sleep operation, as well as send switch signals to the BCM.
CONTROLLED SYSTEMS
The IVMS controls several body-electrical systems. The systems included in the IVMS are as follows:
q Power window system (Refer to GW-16, "POWER WINDOW SYSTEM" .)
q Power door lock system (Refer to BL-19, "POWER DOOR LOCK SYSTEM" .)
q Remote keyless entry system (Refer to BL-53, "REMOTE KEYLESS ENTRY SYSTEM" .)
q Vehicle security (Theft warning) system (Refer to BL-155, "VEHICLE SECURITY (THEFT WARNING)
SYSTEM" .)
q Reverse interlock door mirror system (Refer to GW-81, "REVERSE INTERLOCK DOOR MIRROR SYS-
TEM" .)
q Interior room lamp (Refer to LT-115, "INTERIOR ROOM LAMP" .)
q Step lamp (Refer to LT-143, "STEP LAMP" .)
q Illumination (Refer to LT-165, "ILLUMINATION" .)
q Automatic drive positioner (Refer to SE-13, "AUTOMATIC DRIVE POSITIONER" .)
q Auto light (Refer to LT-6, "HEADLAMP (FOR USA)" .)
q Door warning lamp (Refer to DI-30, "WARNING LAMPS" .)
q Ignition key warning chime (Refer to DI-55, "WARNING CHIME" .)
q Light warning chime (Refer to DI-55, "WARNING CHIME" .)
q Seat belt warning chime (Refer to DI-55, "WARNING CHIME" .)
q Front wiper and washer system (Refer to WW-4, "FRONT WIPER AND WASHER SYSTEM (WITH RAIN
SENSOR)" .)
q Rear window defogger (Refer to GW-61, "REAR WINDOW DEFOGGER" .)
q Trouble diagnosis system
