Supplemental Restraint System (SRS) “AIR
BAG”
NMEC0653
The Supplemental Restraint System such as “AIR BAG” 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 S15 is as follows:
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), a diagnosis
sensor unit, warning lamp, wiring harness and spiral cable.
Information necessary to service the system safely is included in the RS section of this Service Instruction.
WARNING:
I
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.
I
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.
I
Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Instruction. SRS wiring harnesses can be identified with yellow harness connector.
Precautions for On Board Diagnostic (OBD)
System of Engine
NMEC0003
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
I
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 MIL to light up.
I
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MIL to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
I
Be sure to route and secure the harnesses properly after work. The interference of the harness with
a bracket, etc. may cause the MIL to light up due to the short circuit.
I
Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM before
returning the vehicle to the customer.
