Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER" EKS0085Y
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. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
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.
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.
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.

System Description EKS00EKU
The headlamp operation is controlled by the lighting switch which built into the combination switch, BCM and H
IPDM E/R (intelligent power distribution module engine room). Headlamp low relay, headlamp LH and RH
relays are built into IPDM E/R.BCM read combination switch condition. refer to LT-212, "System Description" .
OUTLINE I
Power is supplied at all times
q through 40A fusible link (letter J , located in the fuse and fusible link box),
J
q to BCM (body control module) terminals 74 and 79
q through 20A fuse (No.52, located in the IPDM E/R),
q to IPDM E/R LT
q through 10A fuse [No. 8, located in the fuse block (J/B)].
q to combination meter terminal 27
q to headlamp high LH relay, located in the IPDM E/R, and L
q to headlamp high RH relay, located in the IPDM E/R, and
q to headlamp low relay, located in the IPDM E/R.
With the ignition switch in the ON or START position, power is supplied M
q through 10A fuse [No. 4, located in the fuse block (J/B)],
q to BCM (body control module) terminal 24
q through 10A fuse [No. 2, located in the fuse block (J/B)],
q to combination meter terminal 28
q to IPDM E/R.
Ground is supplied
q to BCM (body control module) terminal 2 and 70
q to combination meter terminals 21, 22 and 23
q through body grounds M19 and M20, and
q to IPDM E/R terminals 3 and 54
q through body grounds E25 (CR engine models), E26 and E40.
Low Beam Operation
When the lighting switch is turned to 2ND position and placed in LOW position, BCM reads combination switch
condition (refer to LT-212, "System Description" ). And BCM sends low beam request signal to IPDM E/R with
LT-7
HEADLAMP -CONVENTIONAL TYPE-
CAN communication line. Then IPDM E/R turns on headlamp low relay. With headlamp low relay is energized,
power is supplied.
q through 15A fuse (No. 39, located in the IPDM E/R)
q through terminal 50 of the IPDM E/R
q to terminal 1 of headlamp LH, and
q through 15A fuse (No. 40, located in the IPDM E/R)
q through terminal 48 of the IPDM E/R
q to terminal 1 of headlamp RH.
Ground is supplied
q to terminal 3 of each headlamp
q through body grounds E25 (CR engine models), E26 and E40.
With power and ground supplied, low beam headlamps will illuminate.
High Beam Operation/Flash-to-Pass Operation
With the lighting switch is turned to 2ND position and placed in HIGH or PASS position, BCM reads combina-
tion switch condition (refer to LT-212, "System Description" ). And BCM sends high beam request signal to
IPDM E/R and combination meter with CAN communication line. Then IPDM E/R turns on headlamp high
relay LH and RH. With headlamp high relays are energized, power is supplied.
q through 10A fuse (No. 34, located in the IPDM E/R)
q through terminal 47 of the IPDM E/R
q to terminal 2 of headlamp LH, and
q through 10A fuse (No. 33, located in the IPDM E/R)
q through terminal 46 of the IPDM E/R
q to terminal 2 of headlamp RH.
Ground is supplied
q to terminal 3 of each headlamp
q through body grounds E25 (CR engine models), E26 and E40.
With power and ground supplied, the high beam headlamps will illuminate.
When combination meter receives high beam request signal from BCM across the CAN communication lines,
combination meter will illuminate high beam indicator.
COMBINATION SWITCH READING FUNCTION
Refer to LT-212, "System Description" .
EXTERIOR LAMP BATTERY SAVER CONTROL
When the headlamp is activated, The headlamps are turned OFF when the door is opened.
FAIL-SAFE FUNCTION
When CAN communication with other control units is impossible, IPDM E/R performs fail-safe control. If the
fail-safe system is operating, headlamps illuminate with low beam when the ignition switch is turned from OFF
to ON and headlamps are turned off when the ignition switch is turn from ON to OFF. During the fail-safe sys-
tem is activated, headlamps will not respond to combination switch no matter what position it is turned to.
Once the CAN communication is back online with the system, fail-safe controls will be deactivated and
headlamp behavior is back to the normal phase. (Refer to PG-20, "FAIL-SAFE FUNCTION" )

CAN Communication EKS00ERC
SYSTEM DESCRIPTION A
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicles are equipped with many electronic control units and each control unit shares information and links B
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
