[POWER DISTRIBUTION SYSTEM]

HIGH FLASHER OPERATION

BCM detects the turn signal lamp circuit status by the current value.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.

FAIL-SAFE CONTROL BY RAIN SENSOR MALFUNCTION

• BCM judges the rain sensor serial link error by the rain sensor serial link condition and detects the rain sen-

sor malfunction by rain sensor malfunction signal.

• When BCM detects the rain sensor serial link error or the rain sensor malfunction while front wiper AUTO

operation, BCM operates a fail-safe control.

NOTE:
If rain sensor malfunction is detected when ignition switch is turned OFF

⇒

ON and front wiper switch is INT/

AUTO position, BCM operates a fail-safe control.

REAR WIPER MOTOR PROTECTION

BCM detects the rear wiper stopping position according to the rear wiper stop position signal.
When the rear wiper stop position signal does not change for more than 5 seconds while driving the rear
wiper, BCM stops power supply to protect the rear wiper motor.

Condition of cancellation

More than 1 minute is passed after the rear wiper stop.

PRECAUTION

PRECAUTIONS

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

INFOID:0000000004757477

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 AIRBAG” and “SEAT BELT” of 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/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 the “SRS AIRBAG”.

• 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

When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors while ignition switch is
ON or engine is running, never use air or electric power tools or strike near the sensor(s) with a hammer.
Heavy vibration may activate the sensor(s), deploy the airbag(s), possibly cause serious injury.
When using air or electric power tools or hammers, always turn OFF ignition switch, disconnect the battery,
and wait 3 minutes or more before performing any service.

Precaution Necessary for Steering Wheel Rotation after Battery Disconnect

INFOID:0000000004757478

NOTE:
• Before removing and installing any control units, first turn the push-button ignition switch to the LOCK posi-

tion, then disconnect both battery cables.

• After finishing work, confirm that all control unit connectors are connected properly, then re-connect both

battery cables.

• Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

If a DTC is detected, perform trouble diagnosis according to self-diagnosis results.

This vehicle is equipped with a push-button ignition switch and a steering lock unit.
If the battery is disconnected or discharged, the steering wheel will lock and cannot be turned.
If turning the steering wheel is required with the battery disconnected or discharged, follow the procedure
below before starting the repair operation.

OPERATION PROCEDURE

Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.

Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)

Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.

Perform the necessary repair operation.

When the repair work is completed, re-connect both battery cables. With the brake pedal released, turn
the push-button ignition switch from ACC position to ON position, then to LOCK position. (The steering
wheel will lock when the push-button ignition switch is turned to LOCK position.)

Perform self-diagnosis check of all control units using CONSULT-III.

SYMPTOM DIAGNOSIS

PUSH-BUTTON IGNITION SWITCH DOES NOT OPERATE

Description

INFOID:0000000004757291

Check that vehicle is under the condition shown in “Conditions of vehicle” before starting diagnosis, and check
each symptom.
NOTE:
The engine start function, door lock function, power distribution system, and NATS-IVIS/NVIS in the Intelligent
Key system are closely related to each other regarding control. The vehicle security function can operate only
when the door lock and power distribution system are operating normally.

Conditions of Vehicle (Operating Conditions)

With Intelligent Key system

• “ENGINE START BY I-KEY” in “WORK SUPPORT” is ON when setting on CONSULT-III.
• Intelligent Key is not inserted in key slot.
• One or more of Intelligent Keys with registered Intelligent Key ID is in the vehicle.

Without Intelligent Key system

Registered keyfob is into the key slot.

Diagnosis Procedure

INFOID:0000000004757292

INSPECTION START

Check the vehicle type.

Which is the type?

With Intelligent Key system>>GO TO 2.
Without Intelligent Key system>>GO TO 4.

PERFORM WORK SUPPORT

Perform “INSIDE ANT DIAGNOSIS” on Work Support of “INTELLIGENT KEY”.
Refer to

DLK-61, "INTELLIGENT KEY : CONSULT-III Function (BCM - INTELLIGENT KEY)"

>> GO TO 3.

PERFORM SELF-DIAGNOSTIC RESULT

Perform Self-Diagnostic Result of “BCM”.
Is DTC detected?

YES

>> Refer to

(instrument center),

(console) or

(trunk room).

>> GO TO 4.

CHECK PUSH-BUTTON IGNITION SWITCH

Check push-button ignition switch.
Refer to

PCS-66, "Component Function Check"

Is the operation normal?

YES

>> GO TO 5.

>> Repair or replace malfunctioning parts.

CONFIRM THE OPERATION

Confirm the operation again.
Is the inspection normal?

YES

>> Check intermittent incident. Refer to
