Supplemental Restraint System (SRS) ªAIR
BAGº
The Supplemental Restraint System such as ªAIR BAGº 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 composi-
tion which is available to NISSAN MODEL D22 is as follows (The composition varies according to the desti-
nation and optional equipment.):
Driver air bag module (located in the center of the steering wheel), a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof D22 Service Manual
Supplement VI.
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 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. SRS wiring harnesses can be identified by yellow harness connector.

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
NEEC0002The 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 in a frontal collision.
The SRS system composition which is available to NISSAN MODEL D22 is as follows (The composition var-
ies according to the destination and optional equipment.):
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 inflation, all maintenance must be performed
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. SRS wiring harnesses can be identified by yellow harness connector.
Precautions for On Board Diagnostic (OBD)
System of Engine
NEEC0003The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver
of a malfunction causing emission deterioration.
CAUTION:
+Be sure to turn the ignition switch OFF and disconnect the negative battery terminal before any
repair or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc.
will cause the MI to light up.
+Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
+Certain systems and components, especially those related to OBD, may use a new style slide-
locking type harness connector.
For description and how to disconnect, refer to EL section, ªHARNESS CONNECTORº.
+Be sure to route and secure the harnesses properly after work. The interference of the harness with
a bracket, etc. may cause the MI to light up due to the short circuit.
+Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to the malfunction of the fuel injection system, etc.
+Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM before
returning the vehicle to the customer.

Basic Multiport Fuel Injection SystemNEEC0014S02The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
time the valve remains open (injection pulse duration). The amount of fuel injected is a program value in the
ECM memory. The program value is preset by engine operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from both the camshaft position sensor and the mass air
flow sensor.
Various Fuel Injection Increase/Decrease CompensationNEEC0014S03In addition, the amount of fuel injected is compensated to improve engine performance under various oper-
ating conditions as listed below.

+When starting the engine
+During acceleration
+Hot-engine operation
+High-load, high-speed operation

System DescriptionNEEC0016S02This system improves engine operation when the air conditioner is used.
Under the following conditions, the air conditioner is turned off.
+When the accelerator pedal is fully depressed.
+When cranking the engine.
+When the engine coolant temperature becomes excessively high.
+When operating power steering and air conditioner during low engine speed or when fully releasing accel-
erator pedal.
+When engine speed is excessively low.

If the engine speed is above 3,000 rpm with no load, (for example, in Neutral and engine speed over 3,000
rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies based on engine speed.
Fuel cut will operate until the engine speed reaches 1,500 rpm, then fuel cut is cancelled.
