PRECAUTION

PRECAUTIONS

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

INFOID:0000000008463009

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.

Service Procedure Precautions for Models with a Pop-up Roll Bar

INFOID:0000000008463010

WARNING:

Always observe the following items for preventing accidental activation.
• Risk of passenger injury or death may increase if the pop-up roll bar does not deploy during a roll

over collision. In order to reduce the chance of an incident where the pop-up roll bar is inoperative,
all maintenance must be performed by a NISSAN or INFINITI dealer.

• Before removing and installing the pop-up roll bar component parts and harness, always turn the

ignition switch OFF, disconnect the battery negative terminal, and wait for 3 minutes or more. (The
purpose of this operation is to discharge electricity that is accumulated in the auxiliary power supply
circuit in the air bag diagnosis sensor unit.)

• When repairing, removing, and installing a pop-up roll bar, always refer to SRS AIR BAG and SRS

AIR BAG CONTROL warnings in the Service Manual.

Precaution for Battery Service

INFOID:0000000008463011

Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.

FRONT WIPER BASIC OPERATION

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the front wiper request signal to IPDM E/R with CAN communication depending on each

operating condition of the front wiper.

• IPDM E/R turns ON/OFF the integrated front wiper relay and the front wiper high relay according to the front

wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation.

FRONT WIPER LO OPERATION

• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the

front wiper LO operating condition.

Front wiper LO operating condition

- Ignition switch ON
- Front wiper switch LO or front wiper switch MIST (while pressing)
• IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).

FRONT WIPER HI OPERATION

• BCM transmits the front wiper request signal (HI) to IPDM E/R with CAN communication according to the

front wiper HI operating condition.

Front wiper HI operating condition

- Ignition switch ON
- Front wiper switch HI
• IPDM E/R turns ON the integrated front wiper relay and the front wiper high relay according to the front wiper

SYSTEM

FRONT WIPER INT OPERATION

• BCM transmits the front wiper request signal (INT) to IPDM E/R with CAN communication depending on the

front wiper INT operating condition and intermittent operation delay interval according to the wiper intermit-
tent dial position.

Front wiper INT operating condition

- Ignition switch ON
- Front wiper switch INT
• IPDM E/R turns ON the integrated front wiper relay so that the front wiper is operated only once according to

the front wiper request signal (INT).

• BCM detects stop position/except stop position of the front wiper motor according to the front wiper stop

position signal received from IPDM E/R with CAN communication.

• BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval.

NOTE:
Factory setting of the front wiper intermittent operation is the operation without vehicle speed. Front wiper
intermittent operation can be set to the operation with vehicle speed by CONSULT. Refer to 

WW-11, "WIPER :

CONSULT Function - WIPER"

.

Front wiper intermittent operation with vehicle speed

• BCM calculates the intermittent operation delay interval from the following
- Vehicle speed signal (received from the combination meter with CAN communication)
- Wiper intermittent dial position

*: When without vehicle speed setting

FRONT WIPER AUTO STOP OPERATION

• BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF.
• IPDM E/R detects the front wiper stop position signal from the front wiper motor and detects the front wiper

motor position (stop position/except stop position).

• When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper

motor returns to the stop position.

NOTE:
• BCM stops the transmitting of the front wiper request signal when the ignition switch is OFF.
• IPDM E/R turns the front wiper relay OFF when the ignition switch is OFF.

FRONT WIPER OPERATION LINKED WITH WASHER

• BCM transmits the front wiper request signal (LO) to IPDM E/R with CAN communication according to the

washer linked operating condition of the front wiper.

• BCM transmits the front wiper request signal (LO) so that the front wiper operates approximately 2 times

when the front washer switch OFF is detected.

Washer linked operating condition of front wiper

- Ignition switch ON
- Front washer switch ON (0.4 second or more)
• IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
• The washer pump is grounded through the combination switch with the washer switch ON.

FRONT WIPER AND WASHER SYSTEM : Fail-Safe

INFOID:0000000008463018

When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN
communication recovers normally, it also returns to normal control.

If No CAN Communication Is Available With BCM

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.

Control part

Fail-safe operation

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.
