Present Error — Open Circuit —
Identify the error circuit using information from the “SELECT SYSTEM” and “CAN DIAG SUPPORT MNTR”
screens.
1. SELECT SYSTEM: Check the items indicated in “SELECT SYSTEM”. Draw a line on the diagnosis sheet
to indicate the error circuit.
NOTE:
CAN communication line has no error if units other than Diag on CAN units are indicated. An error may be
on the power supply of the control unit, DDL1 line or DDL2 line.
a. “TRANSMISSION” which is Diag on CAN unit, is not indicated on “SELECT SYSTEM” screen. This indi-
cates that DLC is not receiving a signal from TCM. Draw a line to indicate an error between DLC and TCM
(line 1-a in the figure).
NOTE:

Diag on CAN units are not indicated on the “SELECT SYSTEM” screen when the CAN line between
Diag on CAN unit and the data link connector is open.

For a description of Diag on CAN, refer to LAN-6, "Diag on CAN" .

PRECAUTIONS
Revision: June 20062007 Versa
PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
UKS005VK
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.
WAR NIN G:

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 When Using CONSULT-IIUKS005YD
Use CONSULT-II CONVERTER when connecting CONSULT-II to data link connector.
CAUTION:
CAN communication does not function properly if CONSULT-II is used without connecting CONSULT-II
CONVERTER.
Precautions for Trouble DiagnosisUKS005YE
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 RepairUKS005YF

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).
