Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The
composition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of 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-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision),
wiring harness, warning lamp (one of components of air bags for a frontal collision).
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 inflation, all maintenance should be per-
formed by an authorized NISSAN 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 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 covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions
+Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to
prevent the internal parts from becoming contaminated by dirt or other foreign matter.
+Disassembly should be done in a clean work area.
+Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could inter-
fere with the operation of the transmission.
+Place disassembled parts in order for easier and proper assembly.
+All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection
or reassembly.
+Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.
+It is very important to perform functional tests whenever they are indicated.
+The valve body contains precision parts and requires extreme care when parts are removed and ser-
viced. Place removed parts in a parts rack in order to replace them in correct positions and sequences.
Care will also prevent springs and small parts from becoming scattered or lost.
+Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
+Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, and to hold bearings and washers in place during assembly. Do not use grease.

DIAGNOSTIC PROCEDURES FOR SYMPTOMS
AT-1097

Self-diagnosis
FUNCTION
+When a problem occurs in the ABS, the warning lamp on the
instrument panel comes on. To start the self-diagnostic
results mode, ground the self-diagnostic (check) terminal
located on ªData Link Connectorº. The location of the mal-
function is indicated by the warning lamp flashing.
+While DIFF-LOCK is on, anti-lock warning light flashes.
SELF-DIAGNOSIS PROCEDURE
Turn off DIFF-LOCK switch.
Drive vehicle over 30 km/h (19 MPH) for
at least one minute.
Turn ignition switch ªOFFº.
Ground terminal ª9º of ªData link connec-
torº with a suitable harness.
Turn ignition switch ªONº while ground-
ing terminal ª9º.
Do not depress brake pedal.
After 3.0 seconds, the warning lamp
starts flashing to indicate the malfunction
code No. (See NOTE.)
Verify the location of the malfunction
with the malfunction code chart. Refer to
the original Service Manual. Then make
the necessary repairs following the diag-
nostic procedures.
After the malfunctions are repaired,
erase the malfunction codes stored in
the control unit. Refer to the original Ser-
vice Manual.
Rerun the self-diagnostic results mode to
verify that the malfunction codes have
been erased.
Disconnect the check terminal from the
ground. The self-diagnostic results mode
is now complete.NOTE: The indication terminates
after five minutes.
However, when the ignition
switch is turned from
ªOFFº to ªONº, the indica-
tion starts flashing again.

PRECAUTIONS AND PREPARATIONZD30DDTi
EC-1005

Installation
+Install the injection tubes, referring to the markings made
during removal.
+Install the injection tubes in the order of No. 3, No. 4, No. 1,
and No. 2.
Injection nozzle oil seal
Removal
Using a tool such as a flat-bladed screwdriver, pry the flange of
the seal, then remove it.
Installation
After the injection nozzle assembly is installed, push the seal
from the cylinder head side until it contacts the flange.
+Replace the oil seal with new one when the injection
nozzle assembly is removed. (It is not necessary to
replace the oil seal when only injection tubes are
removed.)
Spill tube
Installation
+After the spill tube is installed, check the airtightness of
the spill tube.
+After the bolts are tightened, the joint of the spill tube gasket
might be broken. However, this will not affect function.
Injection nozzle assembly
Removal
1. Remove the nozzle support, then pull out the injection nozzle
assembly by turning it clockwise/counterclockwise.
2. Using a tool such as a flat-head screwdriver, remove the
copper washer inside the cylinder head.
CAUTION:
Do not disassemble the injection nozzle.
Installation
1. Insert the nozzle gasket to the cylinder head hole.
2. Attach the O-ring to the mounting groove of the nozzle side,
then insert it in the cylinder head.
TEST AND ADJUSTMENT
WARNING:
When using nozzle tester, be careful not to allow diesel fuel
sprayed from nozzle to contact your hands or body, and
make sure your eyes are properly protected with goggles.

2. Change the diagnostic test mode from Mode II to Mode I by using the data link connector. (See
EC-1035.)
The emission related diagnostic information in the ECM can be erased by changing the diagnostic test mode.
+If the battery is disconnected, the emission-related diagnostic information will be lost after
approx. 24 hours.
+Erasing the emission-related diagnostic information using CONSULT-II is easier and quicker than
switching the diagnostic test mode using the data link connector.
NATS (Nissan Anti-Theft System)
+If the security indicator lights up with the ignition switch
in the ªONº position or ªNATS MALFUNCTIONº is dis-
played on ªSELF-DIAG RESULTSº screen, perform self-
diagnostic results mode with CONSULT-II using NATS
program card. Refer to ªNATS (Nissan Anti-Theft Sys-
tem)º in EL section.
+Confirm no self-diagnostic results of NATS is displayed
before touching ªERASEº in ªSELF-DIAG RESULTSº
mode with CONSULT-II.
+When replacing ECM, initialization of NATS system and
registration of all NATS ignition key IDs must be carried
out with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle
owner. Regarding the procedures of NATS initialization
and NATS ignition key ID registration, refer to CON-
SULT-II operation manual, NATS.
Malfunction Indicator (MI)
DESCRIPTION
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON
without the engine running. This is a bulb check.
+If the MI does not light up, refer to EL section (ªWARNING
LAMPS AND CHIMEº) or see EC-1276.
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.
If MI illuminates or blinks irregularly after starting engine,
water may have accumulated in fuel filter. Drain water from
fuel filter. Refer to MA section.
