PRECAUTIONS
[CAN]
[PCARNE] CAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT A
BELT PRE-TENSIONER"
NKS000N5
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 air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
C
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.
G
Precautions for Battery Service
NKS000N6
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interference between the window edge and the vehicle when the door is opened/closed. During normal operation, the H window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic window function will not work with the battery disconnected.
Precautions When Using CONSULT-II
I
NKS000N7
When connecting CONSULT-II to data link connector, connect them through CONSULT-II CONVERTER.
CAUTION:
J
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
CHECK POINTS FOR USING CONSULT-II
LAN
1. Has CONSULT-II been used without connecting CONSULT-II CONVERTER on this vehicle?
If YES, GO TO 2.
If NO, GO TO 5.
L
2. Is there any indication other than indications relating to CAN communication system in the self-diagnosis
results?
If YES, GO TO 3.
M
If NO, GO TO 4.
3. Based on self-diagnosis results unrelated to CAN communication, carry out the inspection.
4. Malfunctions may be detected in self-diagnosis depending on control units carrying out CAN communication. Therefore, erase the self-diagnosis results.
5. Diagnose CAN communication system. Refer to LAN-5, "TROUBLE DIAGNOSES WORK FLOW" .
Precautions For Trouble Diagnosis
CAN SYSTEM
NKS000N8
q Do not apply voltage of 7.0 V or higher to the measurement terminals.
q Use the tester with its open terminal voltage being 7.0 V or less.
q Be sure to turn ignition switch OFF and disconnect the battery cable from the negative terminal before checking the circuit.

PRECAUTIONS Precautions For Harness Repair
CAN SYSTEM q Solder the repaired parts, and wrap with tape. [Frays of twisted
line must be within 110 mm (4.33 in).]
q Do not perform bypass wire connections for the repair parts. (The spliced wire will become separated and the characteristics of twisted line will be lost.)

When Displaying CAN Communication System Errors
WHEN A MALFUNCTION IS DETECTED BY CAN COMMUNICATION SYSTEM q CAN communication line is open. (CAN H, CAN L, or both) q CAN communication line is shorted. (Ground, between CAN lines, or other harnesses) q The areas related to CAN communication of unit is malfunctioning.

WHEN A MALFUNCTION IS DETECTED EXCEPT CAN COMMUNICATION SYSTEM
C
q Removal and installation of parts: When the units that perform CAN communication or the sensors related
to CAN communication are removed and installed, malfunction may be detected (or DTC other than CAN
communication may be detected).
D
q Fuse blown out (removed): CAN communication of the unit may be stopped at such time.
q Low voltage: If the voltage decreases because of battery discharge when IGN is ON, malfunction may be
detected by self-diagnosis according to the units.

CAN COMMUNICATION System Description

A
NKS000ND
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. Many elec- B 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.
