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.

PRECAUTION
PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000003826050
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.
Precaution Necessary for Steering Wheel Rotation after Battery Disconnect
INFOID:0000000003826051
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
1. Connect both battery cables.
NOTE:
Supply power using jumper cables if battery is discharged.
2. Turn the push-button ignition switch to ACC position.
(At this time, the steering lock will be released.)
3. Disconnect both battery cables. The steering lock will remain released with both battery cables discon-
nected and the steering wheel can be turned.
4. Perform the necessary repair operation.
5. 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.)
6. Perform self-diagnosis check of all control units using CONSULT-III.

SUNROOF
System DescriptionINFOID:0000000003812845
DESCRIPTION
 Sunroof motor assembly and sunshade motor assembly operate with the power supplied from BCM while
ignition switch is ON or retained power is operating.
 Sunroof motor assembly receives an operation signal from sunroof switch, and sends the signal to sunshade
motor by communication line.
 Sunroof motor assembly and sunshade motor assembly receive a vehicle speed signal from combination
meter, and control the sunroof motor and sunshade motor torque during high speed operation.
 The sunroof switch can be operated in the directions of push, open (1st, 2nd) and close (1st, 2nd). It can
operate the sunroof and sunshade by one switch.
OPERATION DESCRIPTION
The sunroof and sunshade operate as per the following by operating the sunroof switch operation.
JMKIA2654GB
(1) PUSH = Tilt up and down.
(2) OPEN: 1st= The sunshade opens during the 1st slide. The sunroof
opens during the 2nd slide.
(3) OPEN: 2nd = The sunshade opens, and then the sunroof opens.
(4) CLOSE: 1st= The sunroof closes during the 1st slide. The sunshade
closes during the 2nd slide.
(5) CLOSE: 2nd =The sunroof closes, and then the sunshade closes.

PAUTO OPERATION
The sunroof or sunshade operates automatically to the fully-open or fully-closes position by operating the sun-
roof switch to the OPEN (2nd) or CLOSE (2nd) position.
RETAINED POWER OPERATION
Retained power operation is an additional power supply function that enables sunroof system to operate for 45
seconds after ignition switch is turned OFF.

ANTI-PINCH FUNCTION
CAUTION:
There are some small distances immediately before the closed position which cannot be detected.
 The CPU of sunroof motor assembly monitors the sunroof condition using the signals from sunroof motor.
When sunroof motor assembly detects an interruption during auto operation (close or tilt down operation),
sunroof motor will tilt up or open [150 mm (5.91 in) or more] sunroof.
 The CPU of sunshade motor assembly monitors the sunshade condition using the signals from sunshade
motor. When sunshade motor assembly detects an interruption during auto close operation, sunshade motor
will open [150 mm (5.91 in) or more] sunshade.

Freeze Frame Data
The BCM records the following condition at the moment a particular DTC is detected.
 Vehicle Speed

 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.
