Precautions for Trouble DiagnosisNKS004PA
CAUTION:

Never apply 7.0 V or more to the measurement terminal.

Use a tester with open terminal voltage of 7.0 V or less.

Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when
checking the harness.
Precautions for Harness RepairNKS004PB

Solder the repaired area and wrap tape around the soldered
area.
NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).

Bypass connection is never allowed at the repaired area.
NOTE:
Bypass connection may cause CAN communication error. The
spliced wire becomes separated and the characteristics of
twisted line are lost.

Replace the applicable harness as an assembly if error is detected on the shield lines of CAN communi-
cation line.

TROUBLE DIAGNOSISPFP:00004
Condition of Error DetectionNKS004PE
“U1000” or “U1001” is indicated on SELF-DIAG RESULTS on CONSULT-III if CAN communication signal is
not transmitted or received between units for 2 seconds or more.
CAN COMMUNICATION SYSTEM ERROR

CAN communication line open (CAN-H, CAN-L, or both)

CAN communication line short (ground, between CAN communication lines, other harnesses)

Error of CAN communication control circuit of the unit connected to CAN communication line
WHEN INDICATED “U1000” OR “U1001” IS INDICATED EVEN THOUGH CAN COMMUNICA-
TION SYSTEM IS NORMAL

Removal/installation of parts: Error may be detected when removing and installing CAN communication
unit and related parts while turning the ignition switch ON. (A DTC except for CAN communication may be
detected.)

Fuse blown out (removed): CAN communication of the unit may cease.

Voltage drop: Error may be detected if voltage drops due to discharged battery when turning the ignition
switch ON (Depending on the control unit which carries out CAN communication).

Error may be detected if the power supply circuit of the control unit, which carries out CAN communica-
tion, malfunctions (Depending on the control unit which carries out CAN communication).

Error may be detected if reprogramming is not completed normally.
NOTE:
CAN communication system is normal if “U1000” or “U1001” is indicated on SELF-DIAG RESULTS of CON-
SULT-III under the above conditions. Erase the memory of the self-diagnosis of each unit.

INSPECTION OF VEHICLE CONDITION

Check whether or not “U1000” or “U1001” is indicated on “SELF-DIAG RESULTS” by CONSULT-III.
NOTE:
Root cause cannot be detected using the procedure in this section if “U1000” or “U1001” is not indicated.

Check whether the symptom is reproduced or not.
NOTE:

Never turn the ignition switch OFF or disconnect the battery cable while the reproducing the error. The
error may temporarily correct itself, making it difficult to determine the root cause.

The procedures for present errors differ from the procedures for past errors. Refer to LAN-25,
"DETECT THE ROOT CAUSE" .

PRECAUTIONS
Revision: 2006 November2007 350Z
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
NKS004PP
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.
Precautions for Battery ServiceNKS0053P
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
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 for Trouble DiagnosisNKS004PR
CAUTION:

Never apply 7.0 V or more to the measurement terminal.

Use a tester with open terminal voltage of 7.0 V or less.

Turn the ignition switch OFF and disconnect the battery cable from the negative terminal when
checking the harness.
Precautions for Harness RepairNKS004PS

Solder the repaired area and wrap tape around the soldered
area.
NOTE:
A fray of twisted lines must be within 110 mm (4.33 in).
