PRECAUTION

PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000009751906

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 AIR BAG” and “SEAT BELT” of this
Service Manual.

WARNING:

Always observe the following items for preventing accidental activation.
• To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in

the event of a collision that would result in air bag inflation, all maintenance must be performed by
an authorized NISSAN/INFINITI 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 “SRS AIR BAG”.

• Never use electrical test equipment on any circuit related to the SRS unless instructed to in this Ser-

vice Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or harness
connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

Always observe the following items for preventing accidental activation.
• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag System sensors with the

ignition ON or engine running, never use air or electric power tools or strike near the sensor(s) with
a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
serious injury.

• When using air or electric power tools or hammers, always switch the ignition OFF, disconnect the

battery, and wait at least 3 minutes before performing any service.

IGNITION RELAY MALFUNCTION DETECTION FUNCTION

• IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it. 
• IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation

coil circuit.

• If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to

alert the user to the ignition relay malfunction when the ignition switch is turned OFF.

FRONT WIPER PROTECTION FUNCTION

IPDM E/R detects front wiper stop position by a front wiper stop position signal.
When a front wiper stop position signal is in the conditions listed below, IPDM E/R stops power supply to wiper
after repeating a front wiper 10 seconds activation and 20 seconds stop.

NOTE:
This operation status can be confirmed on the IPDM E/R “Data Monitor” that displays “BLOCK” for the item
“WIP PROT” while the wiper is stopped.

STARTER MOTOR PROTECTION FUNCTION

IPDM E/R turns OFF the starter control relay to protect the starter motor when the starter control relay remains
active for 90 seconds.

Fail-safe operation

Headlamp

• Turns ON the headlamp low relay when the ignition switch is turned ON
• Turns OFF the headlamp low relay when the ignition switch is turned OFF
• Headlamp high relay OFF

• Parking lamp
• License plate lamp
• Illumination
• Tail  lamp
• Side marker lamp

• Turns ON the tail lamp relay when the ignition switch is turned ON
• Turns OFF the tail lamp relay when the ignition switch is turned OFF

Front wiper motor

• The status just before activation of fail-safe control is maintained until the ignition switch is turned OFF while 

the front wiper is operating at LO or HI speed.

• The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-safe control is activated 

while the front wiper is set in the INT mode and the front wiper motor is operating.

• Returns automatically wiper to stop position when ignition switch is turned ON if fail-safe control is activated 

while front wiper motor is operated and wiper stop in the other position than stop position.

• The status is held at service position if the fail-safe control is activated while the service position function is 

operating.
