PRECAUTIONPFP:00011
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
BKS001TD
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:

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.

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) each turn ON-OFF every 10 ms.
2. Sleep status
–When BCM is in sleep status, transistors of OUTPUT 1 stop the output, and BCM enters low power mode.
OUTPUT 2- 5 send out ON signal every 60 ms, and accept only input from lighting switch (except turn sig-
nal switch) system.
CAN Communication System DescriptionBKS001TH
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-board multi-
plex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected 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.

How to Perform Trouble DiagnosesBKS001TN
1. Confirm the symptoms and customer complaint.
2. Understand operation description and function description. Refer to WW-4, "
System Description" .
3. Perform the Preliminary Check. Refer to WW-18, "
Preliminary Check" .
4. Check symptom and repair or replace the cause of malfunction.
5. Does the front wiper and washer operate normally? If YES, GO TO 6. If NO, GO TO 4.
6. INSPECTION END
Preliminary CheckBKS001TO
CHECK POWER SUPPLY AND GROUND CIRCUIT
1. CHECK FUSES AND FUSIBLE LINK
Check for blown fuses and fusible link.
Refer to WW-11, "Wiring Diagram — WIPER —" .
OK or NG
OK >> GO TO 2
NG >> If fuse or fusible link is blown, be sure to eliminate cause of malfunction before installing new fuse
or fusible link. Refer to PG-3, "
POWER SUPPLY ROUTING CIRCUIT" .
2. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect BCM connectors.
3. Check voltage between BCM harness connector and ground.
OK or NG
OK >> GO TO 3.
NG >> Repair harness or connector.
