Observe the following precautions to ensure safe and proper
servicing. These precautions are not described in each indi-
vidual section.
Precaution for Supplemental Restraint System
(SRS) ``AIR BAG'' and ``SEAT BELT
PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and
``SEAT BELT PRE-TENSIONER'' used along with a seat belt, helps
to reduce the risk or severity of injury to the driver and front pas-
senger in a frontal collision. The SRS system composition which is
available to NISSAN MODEL Y61 is as follows (The composition
varies according to the destination.):
Driver air bag module (located in the center of the steering wheel),
front passenger air bag module (located on the instrument panel on
passenger side), seat belt pre-tensioner, a diagnosis sensor unit,
warning lamp, wiring harness and spiral cable.
Information necessary to service the system safely is included in
theRS sectionof 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 in¯ation, all main-
tenance must be performed by an authorized NISSAN
dealer.
+Improper maintenance, including incorrect removal and
installation of the SRS, can lead to personal injury caused
by unintentional activation of the system. For removal of
Spiral Cable and Air Bag Module, see the RS section.
+Do not use electrical test equipment on any circuit related
to the SRS unless instructed to in this Service Manual.
Spiral cable and wiring harnesses are covered with yellow
insulation either just before the harness connectors or for
the complete harness are related to the SRS.

SMJ connector. Refer to GI-16.
V7Optional splice+The open circle shows that the splice is optional depending on vehicle application.
V8Splice+The shaded circle shows that the splice is always on the vehicle.
V9Page crossing+This arrow shows that the circuit continues to an adjacent page.
+The A will match with the A on the preceding or next page.
V10Common connector+The dotted lines between terminals show that these terminals are part of the same
connector.
V11Option abbreviation+This shows that the circuit is optional depending on vehicle application.
V12Relay+This shows an internal representation of the relay. For details, refer to EL section
(``STANDARDIZED RELAY'').
V13Connectors+This shows that the connector is connected to the body or a terminal with bolt or
nut.
V14Wire color+This shows a code for the color of the wire.
B = Black BR = Brown
W = White OR = Orange
R = Red P = Pink
G = Green PU = Purple
L = Blue GY = Gray
Y = Yellow SB = Sky Blue
LG = Light Green CH = Dark Brown
DG = Dark Green
When the wire color is striped, the base color is given ®rst, followed by the stripe
color as shown below:
Example: L/W = Blue with White Stripe
V15Option description+This shows a description of the option abbreviation used on the page.
V16Switch+This shows that continuity exists between terminals 1 and 2 when the switch is in
the A position. Continuity exists between terminals 1 and 3 when the switch is in
the B position.
V17Assembly parts+Connector terminal in component shows that it is a harness incorporated assem-
bly.
V18Cell code+This identi®es each page of the wiring diagram by section, system and wiring dia-
gram page number.

Number Item Description
V19Current ¯ow arrow+Arrow indicates electric current ¯ow, especially where the direction of standard
¯ow (vertically downward or horizontally from left to right) is difficult to follow.
+A double arrow ``bÐ
c'' shows that current can ¯ow in either direction depending
on circuit operation.
V20System branch+This shows that the system branches to another system identi®ed by cell code
(section and system).
V21Page crossing+This arrow shows that the circuit continues to another page identi®ed by cell code.
+The C will match with the C on another page within the system other than the
next or preceding pages.
V22Shielded line+The line enclosed by broken line circle shows shield wire.
V23Component box in wave
line+This shows that another part of the component is also shown on another page
(indicated by wave line) within the system.
V24Component name+This shows the name of a component.
V25Connector number+This shows the connector number.
+The letter shows which harness the connector is located in.
Example:M: main harness. For detail and to locate the connector, refer to EL sec-
tion (``Main Harness'', ``HARNESS LAYOUT''). A coordinate grid is included for
complex harnesses to aid in locating connectors.
V26Ground (GND)+The line spliced and grounded under wire color shows that ground line is spliced
at the grounded connector.
V27Ground (GND)+This shows the ground connection.
V28Connector views+This area shows the connector faces of the components in the wiring diagram on
the page.
V29Common component+Connectors enclosed in broken line show that these connectors belong to the
same component.
V30Connector color+This shows a code for the color of the connector. For code meaning, refer to wire

+ignition switch is ``OFF'',
+doors, hood and trunk lid/back door are closed,
+pedals are not depressed, and
+parking brake is released.

DETECTABLE LINES AND NON-DETECTABLE LINES
In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
+A line with regular weight (wider line) represents a ``detectable
line for DTC (Diagnostic Trouble Code)''. A ``detectable line for
DTC'' is a circuit in which ECM (Engine Control Module) can
detect its malfunctions with the on board diagnostic system.
+A line with less weight (thinner line) represents a ``non-detect-
able line for DTC''. A ``non-detectable line for DTC'' is a circuit
in which ECM cannot detect its malfunctions with the on board
diagnostic system.
